Photo and Video Chronology - Kīlauea - February 14, 2011

Release Date:

Videos showing an ashy plume rising above Halema‘uma‘u crater, collapse events, lava lake and lava flows, and sounds of the lava lake. Photo of vigorous boiling of the lava surface in Kīlauea's summit vent following vent wall and rim collapses.
 

Video showing ashy plume rising above Kīlauea's summit vent in Halema‘uma‘u crater

Video showing ashy plume rising above Kīlauea's summit vent in Halema‘uma‘u crater. The plume was the result of the collapse of a portion of the vent wall moments earlier.

Video of the lava lake in Halema‘uma‘u crater minutes after a slice of the vent wall had plunged into the lava

Movie of the lava lake in Kīlauea's summit vent in Halema‘uma‘u crater minutes after a slice of the vent wall had plunged into the lava. The lava lake is roiling violently as the recently added wall debris is digested by the lava. Slabs of rock can be seen breaking loose from the base of the overhanging vent wall and falling into the lava. The length of time it takes the rocks to reach the lava surface provides an indication of the size of the hole-it's about 150 m (492 ft) across and the rocks are falling about 60 m (197 ft).

Video of lava flows in Pu‘u ‘Ō‘ō crater from February 6-8

Movie of lava flows in Pu‘u ‘Ō‘ō crater from February 6-8. Lava has been erupting sporadically from three vents within Pu‘u ‘Ō‘ō crater-a cone on the west side of the crater floor (foreground to left), a cone on the northeast side (center frame), and from an opening on the east crater wall (background).

MP3 Sound file of lava lake activity from inside Halema‘uma‘u Crater

Sounds of lava lake activity within Kilauea Volcano's summit vent inside Halema`uma`u Crater on the afternoon of February 14, 2011. The continuous "crashing wave" noise is the sound of churning lava as gases are released from the lake surface, which is in nearly constant motion. The discontinuous sharp "pops" occur when rocks falling from the vent wall hit the lava lake surface. A very faint "clinkery" sound (like broken glass) was also produced by a small rock slide on the vent wall.

Video showing large collapses within Kīlauea

Movie showing the second 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 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.

Vigorous boiling of the lava surface in Kīlauea's summit vent

Vigorous boiling of the lava surface in Kīlauea's summit vent...

Photo of vigorous boiling of the lava surface in Kīlauea's summit vent following vent wall and rim collapses earlier in the day. The rim of the vent on the floor of Halema‘uma‘u is about 150 m (yards) across. The lava surface is about 100 m (yards) below the rim.
