VIDEO: Shown at 30x speed, this video highlights changing activity on the surface of the water pond. Steam wafting above the pond shifts in the wind, and circulation of the water is evident in areas of sharp color boundaries. USGS video by M. Patrick, 09-17-2019.
VIDEO: Views of the water pond in Halema‘uma‘u on Friday, September 6, and Monday, September 9 are shown in this video. Ripples are evident on the pond, presumably due to wind moving over the water surface. No significant changes in the pond were observed over the weekend, and the water level continues to slowly rise. USGS video by M. Patrick.
This video shows a close-up of the water pond at the bottom of Halema‘uma‘u on August 13, 2019. Steaming from the water surface shows the shifting winds over the pond.

This 3D model of the Pu‘u ‘Ō‘ō crater was constructed from thermal images taken during a recent helicopter overflight. White areas show warm spots in the crater. Despite the absence of active lava in Pu‘u ‘Ō‘ō, changes at the crater have continued since magma drained from beneath it on April 30, 2018. The shape of the crater continues to change through occasional small collapses within it. The crater is now roughly 290 m (950 ft) deep.
This 3D model of Pu‘u ‘Ō‘ō's crater was created from thermal images during an overflight of the cone. The deepest portion of the crater is about 320 meters (1050 feet) below the crater floor that existed prior to April 30.
A closer view of the small cone forming on the floor of crater within fissure 8 today (Sept. 5). By this morning, bits of molten lava emitted from the cone every few seconds had built it up to an estimated height of around 3-4 m (about 10-13 ft).
During an overflight of fissure 8 this morning, HVO geologists observed low-level spattering on the new pad of lava within the cone. Slow-moving lava had just barely entered the spillway, but was not advancing down the channel.
During this morning's overflight, HVO geologists observed low levels of lava fountaining within the fissure 8 spatter cone and crusted lava in the spillway and channel downstream. The significance of this change is not yet clear. Eruptions can wax and wane or pause for days to weeks before returning to high levels of lava discharge. New outbreaks in the area of the active fissures could also occur in the near future.
This lava, erupted from fissure 8 on Kīlauea Volcano's lower East Rift Zone, shows classic pāhoehoe behavior. Exposed to the air, the surface of the flow chills to form a thin crust that can be stretched or broken apart, forming pieces of crust that are "subducted" back into the molten interior. The main sound is wind noise, but crackles can also be heard as flakes of glassy lava pop off the top of the solid crust as it stretches and moves.
During HVO's early morning helicopter overflight along the coastline, orange streams of lava were entering the ocean in the vicinity of Ahalanui. Strong trade winds were pushing the white laze plumes inland.

Listen to the sounds of rockfalls at Kīlauea Volcano's summit in this short video taken from the northeast rim of the caldera. At 2:42 p.m. HST on July 12, 2018, a collapse/explosion event at Kīlauea's summit released energy equivalent to a magnitude-5.3 earthquake. Rockfalls that occurred in Halema‘uma‘u and along the steep summit caldera walls during the event can be heard in this video.
This compilation of video from HVO's early morning overflight of Kīlauea Volcano's lower East Rift Zone shows (1) lava from fissure 8 moving through a perched channel toward the northeast, (2) the diverted channelized ‘a‘ā flow west of Kapoho Crater, and (3) a vigorous ocean entry along the southern coastline in the vicinity of Ahalanui Beach Park (Warm Ponds).
Lava oozes from a small breakout near the fissure 8 channel on Kīlauea Volcano's lower East Rift Zone. HVO field crews track the fissure 8 overflows, breakouts and lava channel behavior as conditions allow, and report information to the Hawaii County Civil Defense Agency.
In this video taken from the Leilani Estates subdivision, lava at fissure 8 pulses above the cinder cone adding fragments of lava (spatter) that build the cone higher. From fissure 8, lava flows freely over small cascades (rapids) into a well-established channel. Near the vent, lava is traveling about 24 km per hour (15 mi per hour). Lava slows to about 2 km per hour (1.5 mi per hour) near the ocean entry at Kapoho.
Aerial views of the ocean entry on Kīlauea Volcano's lower East Rift Zone on June 12, 2018, around 6:30 a.m. HST, show multiple small lava streams spilling into the ocean along the southern portion of the lava delta in Kapoho Bay.
The interaction of molten lava flowing into cool seawater causes pulsating "littoral explosions" that throw spatter (fragments of molten lava) and pieces of solidified glassy lava (black sand, Pele's hair, limu o Pele) high into the air.
Three closely spaced lava fountains at fissure 8 continue to feed a channelized flow trending north and then east to the ocean entry at Kapoho Bay. This video is from an HVO helicopter overflight of the braided lava channel this morning around 6:30 a.m. HST. Minor overflows of the channel levees have occurred at several places along the channel, but have been short-lived and do not pose an immediate threat to areas not previously covered by lava.
Video of the lava ocean entry during today's late afternoon overflight of the lower East Rift Zone. The main steam plume marks location where the primary lava channel enters the ocean.
Video of the lava fountain and flow (left) from fissure 8. Only the tallest waves of the channelized flow can be seen in the video.
Beginning on June 3, lava from fissure 8 entered the ocean at Kapoho Bay. By June 6, lava had completely filled Kapoho Bay and built a delta that now extends over a mile from shore.
This short video compilation shows conditions at Kapoho Bay during a helicopter overflight on June 4, 2018, around 6:15 a.m. HST and again around 1:38 p.m. HST.
Video from helicopter overflight of Kīlauea Volcano's lower East Rift Zone on June 4, 2018, shows lava from fissure 8 entering the ocean at Kapoho Bay. View to the north.
Video of fissure 8, as observed during a helicopter overflight on May 29, 2018, and as viewed from ground level. Fissure 8 was fountaining to heights of 200 feet at times, and feeding a lava flow that was traveling to the northeast.
Fissure 8, one of the westernmost active fissures on Kīlauea Volcano's lower East Rift Zone, reactivated during the overnight hours of May 25-26, with chaotic bursts of gas and lava spatter. A mini-spatter cone (far right) near fissure 8 was also constantly active.
This explosion at Kīlauea Volcano's summit, which occurred just after 6:00 p.m. HST on May 24, 2018, produced an ash cloud that rose to 10,000 feet above sea level. Moderate trade winds were blowing to the southwest at the time, and light ash fell in downwind locations. Earthquakes in the summit area continue at a moderate rate, as does deflation of the summit region, both of which reflect the withdrawal of magma from the summit.

Compilation of three short videos from helicopter overflights of the fissure complex, in Kīlauea Volcano's lower East Rift Zone on May 22, 2018. Fissure 22 is the dominant fissure, with lava fountaining to 50 m (about 160 ft) or more in height.
Helicopter overflight of lower East Rift Zone ocean entry and fissure complex on May 23, 2018, around 8:00 AM HST.
A blue burning flame of methane gas was observed in the cracks on Kahukai Street during the overnight hours. When lava buries plants and shrubs, methane gas is produced as a byproduct of burning vegetation. Methane gas can seep into subsurface voids and explode when heated, or as shown in this video, emerge from cracks in the ground several feet away from the lava. When ignited, the methane produces a blue flame.
A helicopter overflight of Kīlauea Volcano's lower East Rift Zone shows the interaction of lava and seawater to produce a laze plume. Laze is formed when lava enters the ocean. The interaction sends hydrochloric acid and steam with fine glass particles into the air. Laze drifts with the wind and can be a health hazard for people in the immediate vicinity of the plume, but it dissipates quickly downwind. Laze is irritating to the lungs, eyes and skin. The video also shows the rapid fragmentation
Lava spatter and splashing build cones at Fissure 22, in Kīlauea Volcano's lower East Rift Zone. This video from May 21, 2018, ~8:50 AM, HST, shows how splashing and spattering lava builds cones around fissure sites. The height of the cone at the lower fountain (to the left) is about 14 m (~45 ft). The height of the large lava fountain in the middle is about 46 m (~150 ft).
Fissure fountains feed lava flows, as shown in this overflight video of the Fissure 20 complex on May 21, 2018, around 7:20 AM, HST. The video concludes with a view of the bifurcating lava channels that merge closer to the coast (and split again before ocean entry). The white laze plume is the site of ocean entry.
Spattering and lava flow along north side of fissure 20 on May 19, 2018, at 4:00 AM HST. The flashes in the foreground are from methane bursts. Lava from the large fissure in the foreground is building a small cone. The audio is the sound of lava fountaining.

Spattering at Fissure 17 around 12:30 AM HST, on May 18, 2018. The audio is the sound generated by the jetting of magma and gases from the fissure.
Aerial view (from a helicopter) of spattering between fissures 16 and 20, Kīlauea Volcano Lower East Rift Zone, at approximately 7:30 AM HST on May 16, 2018. The audio is the sound of the helicopter.
This video shows spattering at fissure 18, Kīlauea Volcano's Lower East Rift Zone, at approximately 2:00 AM HST on May 16, 2018. The audio captures the sounds of explosions and burning vegetation.
Aerial view of fissure 17 around 4:30 p.m. HST. On the west end of the flow, intermittent percussive jetting threw spatter and lava bombs up to 500 feet above the ground. East margin of the ‘a‘ā flow was cascading into a pit or graben.
VIDEO: Fissure 16 eruption at 12:57 p.m. HST on May 12, 2018. Video by Cheryl Gansecki, University of Hawaii.
Video: Good weather provided clear views into Pu‘u ‘Ō‘ō crater. The crater floor collapsed on April 30 as magma drained to the east along the East Rift Zone. Based on a 3D model constructed from thermal images, the deepest part of the crater was 350 m (1150 ft) below the crater rim.
VIDEO: Fissure eruption on Luana Road, between Leilani and Malama, in the Leilani Estates subdivision, at 9:37 p.m. HST on May 5, 2018. Fountains reached heights of up to 100 m (about 330 feet). Video by Bruce Houghton, USGS and University of Hawaii.
Fissure 3 opened around 6:00 a.m. HST on Friday, May 4, with weak fuming from a crack on Kaupili Street. This fuming increased, as did rumbling sounds. Eventually spatter was ejected and accumulated around the fissure. Large, loud bubble bursts were common at this fissure.
Fissure 2 opened around 1:00 a.m. HST on Friday, May 4, with a small area of spattering in a residential driveway. Within an hour the spattering was more vigorous, with spatter reaching about 30 meters (100 feet). This spatter was thrown over the power lines and landed on Makamae Street.
This video shows the small fissure that opened in the Leilani Estates subdivision today around 5:00 p.m. The fissure was active until about 6:30 p.m.
On Kīlauea Volcano's summit, the Halema‘uma‘u lava lake's high standing lake level produced intermittent overflows onto the crater floor. Smaller overflows and spattering have started to build a few discontinuous levees and a spatter cone around the lake margin, shown in these video clips taken from the lakes north and northeastern margin.
Vigorous overflows from Kīlauea's summit lava lake covered a large portion of the floor of Halema‘uma‘u this morning. In this video, the view starts from the north and heads south, showing the north and east sides of Halema‘uma‘u crater. During the overflight, a large overflow was active on the north margin of the lava lake, sending a cascade of lava down the elevated lake rim.
This video shows an overview of the lake from the Halema‘uma‘u Crater rim, as well as some of the spattering that was occurring on the lake margin on Sunday, April 22.
This time-lapse image sequence taken by a time-lapse camera on the rim of Pu‘u ‘Ō‘ō's west pit, spans March 20 to April 18. The sequence, of approximately one image per day, shows the growth of the lava pond within the west pit as it developed into a perched lava pond. This sequence is looped 4 times.
Video: At 10:28 a.m. HST this morning (April 6), rock falls from the Overlook crater wall into Kīlauea Volcano's summit lava lake triggered an explosive event. This video, taken by the K2cam, shows a dark pulsing plume of ash and debris. The explosion hurled spatter (molten lava fragments) and lithic blocks (older crater wall) onto the rim at the old visitor overlook and to the southwest. This area is closed to the public due to volcanic hazards such as today's event.
This video shows typical spattering in the summit lava lake in Halema‘uma‘u Crater. Spattering is driven by the bursting of large gas bubbles. The surface crust tends to flow into the spattering sites, where the crust is shredded and sinks.
This video clip shows typical pāhoehoe breakouts on the coastal plain, as well as a small channelized ‘a‘ā flow on the pali.
A shatter ring forms and grows on the Kamokuna lava delta. This video shows repeated uplift and subsidence of the delta surface by the lava supply under the surface. This process creates a large round rubble pile, called a shatter ring. The uplift is caused by extra lava accumulating in the tube, either from more volume coming in, or from a blockage that does not allow lava to pass through easily. This extra lava needs space, and lifts the rock above it to make that space. If the rock breaks, wh
A shatter ring forms and grows on the Kamokuna lava delta. This video shows repeated uplift and subsidence of the delta surface by the lava supply under the surface. This process creates a large round rubble pile, called a shatter ring. The uplift is caused by extra lava accumulating in the tube, either from more volume coming in, or from a blockage that does not allow lava to pass through easily. If the rock breaks, which often happens around the base at the flexure point, then lava can flow ou
Spattering is common in Kīlauea Volcano's summit lava lake, and consists of many large bursting gas bubbles. The fluid nature of the lake can be seen when lava hits the wall and flows downward like syrup. The thin, flexible nature of the crust is also shown here, as the bursting gas bubbles rip and fold the thin skin on the lake. This video was taken from the rim of Halema‘uma‘u, an area that remains closed to the public due to ongoing volcanic hazards.
This video clip shows spattering along the south margin of the summit lava lake. Note the large slab of crust migrating into the spatter site, where it is consumed. Unfortunately, wind noise masks much of the spattering sound in this video.
This video clip shows Kīlauea Volcano's Kamokuna ocean entry, with the steam plume rising from the front of the lava delta. Recent flows have covered the surface of the delta with fresh lava.
This video clip shows HVO geologist Tim Orr sampling lava from an active pāhoehoe breakout on the episode 61g lava flow. The chemistry of these lava samples provides information on the magma plumbing system. Sampling has been a regular part of monitoring Kīlauea Volcano's ongoing Pu‘u ‘Ō‘ō eruption.
This video clip shows the Kamokuna ocean entry, with the laze plume blocking the view of the delta. The billowing white cloud rising from the ocean entry is a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.
VIDEO: Kīlauea Volcano's Kamokuna ocean entry. Today, the "firehose flow" could be clearly seen from the public lava viewing area, 800 meters (about one-half mile) east of the ocean entry, in Hawai‘i Volcanoes National Park.
VIDEO: The section of sea cliff above the ocean entry collapsed today at about 12:55 p.m. The sea cliff had become increasingly unstable as a large crack 5–10 m (16–33 ft) inland of the ocean entry had more than doubled in width, from 30 cm (1 ft) to 70 cm (2.5 ft), over the past several days. A video camera, which had just been set up to monitor movement of the crack near the sea cliff, captured the moment of collapse.
This video clip shows the open lava stream pouring into the ocean. Frequent littoral explosions throw bits of lava to heights of over 27 m (30 yards).
This video shows a close-up of the base of the lava stream, where ripples in the narrow sheet of lava are visible.
This video shows a wider view of the open lava stream at the ocean entry, and the frequent littoral explosions.
This video clip shows the lava stream - about 1-2 m or yards wide - pouring out of the tube into the Pacific Ocean, triggering pulsating explosions that are throwing bits of lava onto the top of the sea cliff.
This video clip of Kīlauea Volcano's summit lava lake shows spattering along the southeast margin of the lake.
This VIDEO CLIP shows a cloud of ash and spatter being thrown from the summit lava lake during today's explosive event. The images were captured by an HVO webcam located on the rim of Halema‘uma‘u Crater, just above the rockfall area. Spatter falling onto the crater rim is a reminder of the hazards that exist in this area, which has been closed since 2008.
This video clip shows typical spattering activity in Kīlauea's summit lava lake. This spattering was occurring along the eastern margin of the lake on the evening of October 5.
This video shows spattering in two locations of Kīlauea's summit lava lake. In the first segment, spattering is active in a small area in the southern portion of the lake. In the second segment, spattering on the east margin of the lake has created an overhanging ledge with dangling lava stalactites.
This video clip shows the northern portion of the lava lake, where episodic bubbling commonly occurs. The northern margin of the lake is in the upper right portion of the photo. Note how the bubbling occurs in the same general area, regardless of the movement of the crustal plates. The video is shown at 20x speed.
This video clip shows a few of the lava breakouts active on Kīlauea's coastal plain on September 20. The activity consisted of scattered pāhoehoe breakouts. The final segment in this video is shown at x20 speed.
This video clip, filmed on August 12, 2016, shows a typical pāhoehoe breakout on Kīlauea Volcano's "61g" lava flow (actual speed). Since the ongoing East Rift Zone (Pu‘u ‘Ō‘ō) eruption began in 1983, the net result of countless pāhoehoe flows like this is that 142 square kilometers (55 square miles) of federal, state, and private land on Kīlauea Volcano have been covered by lava.
Video showing a small channelized flow, as well as the skylight described above, on the breakout on the east flank of Pu‘u ‘Ō‘ō.
When large rockfalls impact the lava lake, they trigger explosive events that propel volcanic rock fragments (tephra) upward. This morning's event was vigorous enough to hurl incandescent fragments onto the rim of Halema‘uma‘u Crater, about 110 m (360 ft) above the lava lake surface. This Quicktime movie shows some of these fragments flying toward the USGS Hawaiian Volcano Observatory webcam that is perched on the rim of the crater. Rockfalls and subsequent explosive events occur with no warnin
This Quicktime movie shows the same rockfall as captured by the USGS Hawaiian Volcano Observatory webcam perched on the rim of Halema‘uma‘u Crater. Note the fragments of molten lava flying toward the camera—just one of the hazards that led to the closure of this area.
This Quicktime movie shows spattering at the margin of the summit lava lake in Halema‘uma‘u Crater. Spattering has been common at the lake, and when it occurs is easily visible from the public viewing area at Jaggar Museum. This video shows a closer view from the rim of Halema‘uma‘u, which is closed to the public due to volcanic hazards.
This Quicktime movie shows a small explosive event that occurred at 1:20pm today at the summit lava lake. A collapse of a portion of the Halema‘uma‘u Crater wall impacted the lake and triggered an explosion of spatter. Fist-size clasts were found scattered along the rim of Halema‘uma‘u Crater near the closed visitor overlook.
Quicktime movie of the rockfall and subsequent explosion at 10:20 a.m., HST, on April 28, 2015. Rocks falling into the summit lava lake generated an explosion that threw large fragments of molten lava onto the rim of Halema‘uma‘u Crater, 85 m (280 ft) above the lake. These fragments pose a significant hazard, and are one reason this area remains closed.
The lava lake in the Overlook Crater, within Halema‘uma‘u Crater at the summit of Kīlauea Volcano, has been rising over the past few days. Today the lava was as high as 14 meters (46 feet) below the Overlook crater rim. Several areas of spattering were active along the lake margin.

This Quicktime video provides an aerial view of the activity at the front of the June 27th lava flow.
This Quicktime movie shows activity at the front of the June 27th lava flow. The flow front continues to advance eastward, with lava issuing out of a ground crack and spreading through dense forest, creating thick plumes of smoke. The farthest lava this afternoon was 1.3 km (0.8 miles) from the eastern boundary of the Wao Kele o Puna forest reserve.
The Quicktime video begins with a view of the steaming ground crack, where lava is moving deep within the crack. As the view rotates west, lava can be seen on the surface burning thick forest. Finally, the camera focuses on the eastern edge of the flow, where lava is plunging into the deep ground crack. This swiftly moving stream of lava was about 2 meters (yards) wide, and was visible down to about 30 meters (100 feet) depth in the crack, where it disappeared from view.
The June 27th lava flow remains active at its leading edge, where lava is spreading out slowly into thick forest and also plunging into one of the many deep ground cracks that form Kīlauea's East Rift Zone. This Quicktime video shows the activity near the eastern edge of the flow. This swiftly moving stream of lava was about 2 meters (yards) wide, and was visible down to about 30 meters (100 feet) depth in the crack, where it disappeared from view.
This Quicktime movie shows the southern front of the June 27th lava flow from Pu‘u ‘Ō‘ō. Lava here has flowed into a deep crack on Kīlauea's East Rift Zone. The line of steam extending out from the visible flow margin at the surface is inferred to be caused by lava deep within the crack. This video also shows the lava stream beneath the flow surface, supplied by a lava tube, plunging into the crack.
Movie from a webcam positioned in the observation tower at the Hawaiian Volcano Observatory, next to Jaggar Museum, near the summit of Kīlauea, showing the July 23 explosive event. The movie images were captured at 2 frame/second, and the playback speed is 12 frames/second.
This Quicktime movie shows activity in the lava pond in the northeast portion of Pu‘u ‘Ō‘ō crater. A lava pond has been here for months, but it enlarged considerably during the June 27 breakout as the lava level in the pond dropped.
Mar 7, 2014: This Quicktime movie shows Kīlauea's summit lava lake in Halema‘uma‘u Crater. A persistent spatter source is active on the lake margin.
Mar 7, 2014: This Quicktime movie shows the lava pond in Pu‘u ‘Ō‘ō crater, which was undergoing "gas pistoning". Gas pistoning is the cyclic rise and fall of the lava surface, driven by the buildup and release of gas in the lava pond. This sequence shows the drop of the lava level, which corresponds with vigorous spattering and agitation of the pond surface.
This Quicktime movie shows a time-lapse sequence of activity at the northeast spatter cone in Pu‘u ‘Ō‘ō crater on February 9-10. Rapid fluctuations in the height of the lava pond are caused by gas pistoning, which is the gradual buildup and release of gas in the pond. Mauna Kea is visible in the upper right portion of the frame. The sequence was captured by an inexpensive time-lapse camera, whose plastic housing was warped by the extreme heat.
This Quicktime movie shows typical activity at the summit lava lake. Spattering at the summit lava lake has been common over the past several years, and today's winds provided a clear view of the primary spatter area on the lake margin. The lava lake today was about 50 m (160 ft) below the floor of Halema‘uma‘u Crater. The spattering is driven by bursting gas bubbles, with spatter thrown as high as 30 m (100 ft).
This Quicktime movie shows some of the spattering associated with the gas pistoning, in which the spattering acts as an outlet for gas accumulating in the pond. Note how the crust in the center of the pond is fluctuating. Lava pond activity and gas pistoning are common in Pu‘u ‘Ō‘ō.
This Quicktime movie shows weak gas pistoning in the lava pond on the east rim of Pu‘u ‘Ō‘ō. Gas pistoning is the cyclic buildup and release of gas within the pond, and is common in Pu‘u ‘Ō‘ō.
This Quicktime movie shows a lava pond, about 15 m (50 ft) in diameter, on the east rim of Pu‘u ‘Ō‘ō. Several small spatter sources are active on the pond margin, and release gas from within the pond. Lava pond activity like this is common in Pu‘u ‘Ō‘ō.
This short Quicktime movie shows spattering from a cone near the south rim of Pu‘u ‘Ō‘ō crater as a short lava flow is erupted.
Farther down the flank of Pu‘u ‘Ō‘ō a skylight on the Kahauale‘a flow provided a view of the flowing lava stream in the lava tube.
This Quicktime movie shows a time-lapse sequence of the lava lake captured by a thermal camera on the rim of Halema‘uma‘u crater. The sequence is shown at a speed of about 30 times actual. By viewing the sequence at this speed, spotting the upwelling area in the lake is easier than in a still photograph.
Quicktime video, taken from the east rim of Pu‘u ‘Ō‘ō crater, showing the small lava lake that is active in the northeast portion of the crater floor. Unsteady gas escape along the lake margins drives low-level spattering and undulations of the lake surface.
Video taken during today's helicopter overflight of Halema‘uma‘u, showing the active lava lake at a very high level (described in more detail in the caption above). Vigorous spattering on the lake margin emits a thick plume of gas.
Video zoomed in on the spattering at the west edge of the lava lake in the 'overlook' vent in Halema‘uma‘u.
This Quicktime movie shows the impressive spattering at the western margin of the lava lake at Halema‘uma‘u. The continuous spattering is often punctuated by bursts which throw lava onto the ledge (left portion of image), and this accumulating lava is building a spatter rampart. If you focus on the right portion of the image, you can see the slow migration of the lava lake surface crust towards the spatter source, where lava sinks back into the magmatic system.
Video showing a 6 m (20 ft) high lava cascade near the eastern base of Pu‘u ‘Ō‘ō. This is the same lava stream shown in the previous two videos. The lava stream continues on several hundred more meters (yards) before transitioning into rubbly pāhoehoe and ‘a‘ā and stalling well short of yesterday’s flow front, which is now inactive.
Video showing the main lava stream on the lower east flank of Pu‘u ‘Ō‘ō. This stream carries most of the lava—the rest splits off to the south (to the left) and flows behind the mounds at upper left. The previous video shows the section of the stream visible at upper right. The lava stream here is about 4 m (13 ft) across, 2 m (7 ft) deep, and is moving at speed of about 3 m per second (10 ft per second).
This Quicktime movie shows activity at some of the individual vents, which are each distinct in their behavior.
This Quicktime movie shows views of the numerous spattering vents during today's overflight. Spattering at each source is creating spatter cones and ramparts, and the lava issuing from the individual vents is creating a series of narrow streams which join to feed a broader flow channel.
This Quicktime movie shows a timelapse sequence taken from a thermal camera on the south rim of Pu‘u ‘Ō‘ō, beginning just before noon on August 3. Just after 2pm, the lava lake and surrounding floor abruptly drop. As the lava lake drops, solidified portions of the crater floor slide into the fluid lava. By the end of the sequence, the floor of the crater is composed of only hot rubble and inclined blocks of the pre-existing crater floor. The temperature scale is degrees Celsius.
Movie showing the fourth of five large collapses within Kīlauea's summit vent on the floor of Halema‘uma‘u. The collapse was captured by a Webcam located on the rim of Halema‘uma‘u directly above the erupting vent.

Movie of the January 21 collapse and dusty plume captured by a Webcam located in the observation tower at the Hawaiian Volcano Observatory.
Movie of the January 17 collapse and explosive eruption captured by a Webcam located on the rim of Halema‘uma‘u directly above the erupting vent.
Quicktime movie showing a close-up of spattering at the south edge of the lava lake in the vent at Halema‘uma‘u.
As the spattering shown in the previous video intensifies, the walls of the vent heat even more, causing the cracking of the rocks through thermal expansion to speed up, creating the cacophony of popping noises apparent in this video.
The level of the lava lake sometimes changes abruptly. These cycles of rise and fall, which amount to a vertical change of around 15 m (about 50 ft), are occasionally triggered by rockfalls. Here, a small collapse from the vent wall triggers degassing and a drop in the lava level.
This clip, captured by a video camera on the rim of Halema‘uma‘u to the southwest of the vent, shows a small slice of the western rim of the vent collapsing into the lava lake and includes sound.
This video, also compiled from the Webcam on the rim of Halema‘uma‘u, shows the north rim of the vent collapsing.
Video clip shot in front of the propagating fissure, showing low spattering that started moments earlier. Thick white steam from the crack in the foreground indicates that lava is about to reach the surface, and is seen doing so seconds later.
Video showing spattering from the most persistent vent of the day just west of the base of Pu‘u ‘Ō‘ō near the northeastern end of the fissure system.
