At 11:10 in the morning on November 28, 2005, the active lava delta at East Lae'apuki began to fall into the ocean. This was not a catastrophic collapse, with the entire 34-acre delta going at once, but instead occurred in a piece-meal fashion over a period of just less than 5 hours.

East Lae'apuki Lava Delta Collapse (November 28, 2005)
At 11:10 in the morning on November 28, 2005, the lava delta at the East Lae'apuki ocean entry, on Hawai'i's southeastern coast, began to collapse into the ocean. This was not a catastrophic failure with the entire 34-acre delta going at once, but instead occurred in a piece-meal fashion over a period of just less than 5 hours.

Mount St. Helens' Crater Glacier's response to lava dome growth
From 2005 to 2010, the U.S. Geological Survey-Cascades Volcano Observatory operated a remote camera on the northwest flank of Mount St. Helens. Looking into the crater, the camera captured hourly photographs of volcanic dome growth during the 2004-2008 eruption.

Mount St. Helens: Instrumentation and Dome Growth, Sept 2005-Feb 2006
Events that occurred in the crater during the 2004–2008 eruption were recorded by a network of seven remote, telemetered digital single-lens reflex (DSLR) cameras installed on the crater floor and rim. The resulting time lapse images constitute a valuable and visually compelling record of dome growth and the resulting response of Crater Glacier.

Grizzly Bear Claws and Licks Camera
Grizzly bear paws and licks one of our remote cameras and eventually pushes it off the tree. The camera container had a screw top lid that moves as the bear paws at it; the camera was not damaged (Make sure you have your sound on for this).

Grizzly Under Barbed Wire
Grizzly bear goes under barbed wire into a hair snag station, sniffs scent lure pile, and leaves. DNA analysis of hair deposited on the barbs identifies the bear for a study of bear population size.

Lava Pond Spattering and Overflow at the MLK Vent
(May 10, 2005, 16:20:29 to 18:30:29) After the collapse of the main spatter cone at the MLK vent (see movies "Spatter cone collapse at the MLK vent"), a small lava pond was visible within the new pit. At times, the level of the lava pond rose abruptly, overflowing the rim of the pit.

Pond Overflow at MLK Vent (May 10, 2005)
After the collapse of the main spatter cone at the Martin Luther King (MLK) vent on May 2, 2005, a small lava pond was visible within the new pit. Over the following weeks, the level of the lava pond often changed abruptly, resulting in overflows and spattering along the edge of the pond.

Spatter Cone Collapse at MLK Vent
(May 2, 2005, 02:30:28 to 07:30:37) The spatter cone collapse described in the movie below was also recorded by a time-lapse camera on the west flank of the Pu‘u ‘Ō‘ō cone. This camera was located about 70 meters from the MLK vent and recorded two pulses of lava effusion from the vent before collapse.
