An explosion at 3:13am from the vent in Halema`uma`u ejected hot particles about a hundred yards above the vent rim, and several tens of yards above the Halema`uma`u Overlook. This Quicktime movie (shown at x2 speed) shows the event captured by a low-light camera in the HVO observation tower.

movie shows a view into the Halema`uma`u vent cavity with a thermal camera. To the naked eye, the vent is entirely obscured by thick fume, but the thermal camera can 'see' through much of this and provide views of the cavity interior. These views show four puffing holes on the floor of the cavity. North is to the right.

movie shows two degassing holes on the floor of the Halema`uma`u cavity. Lava is just below the rim of the two holes, creating frequent spattering which falls around their rims. Within the larger of the two (on the right), lava can be seen vigorously sloshing. For scale, these openings are about 10 yards wide.

The December 2004 Indian Ocean Tsunami was one of the deadliest natural disasters of modern history, killing over 225,000 people. As a result of this catastrophe, the U.S. Geological Survey has partnered with the international community to create an Indian Ocean Tsunami Warning System (IOTWS).

This film presents a summary of the natural hazards of Hong Kong. Such natural hazards include earthquakes, typhoons, tsunamis, and landslides.

This film presents a summary of the natural hazards and resources of Thailand. It explores the different types of hazards that Thailand needs to be prepared for: flooding, drought, storm surges, earthquakes, and tsunamis. This film also presents the Thai Meteorological Department that monitors and reports earthquake and tsunami activity.

This film depicts the effects of the Wenchuan Earthquake in China on May 12, 2008. This was filmed May 23-26, 2008 in Sichuan by Yingying Huang. The film captures the devastation of the Wenchuan Earthquake as experienced by the local population, as well as effects on the buildings and monuments.

movie shows a recent instance of the Halema`uma`u changing from its typical white to a dusty brown. The brown plume events are normally associated with collapses of the cavity walls.

movie shows a view into the Thanksgiving Eve Breakout (TEB) lava tube, thanks to a skylight (a hole in the roof of the tube). The lava stream, which is about two yards below the skylight, is moving swiftly downhill (the video is shown at actual speed), towards the Waikupanaha ocean entry.

This four minute short movie depicts the hatching of a Mojave Desert Tortoise. This is the continuation of a sixty million year process for this threatened species. One of the surprising moments in the movie is when the hatchling tumbles from its shell and is propped up by its yolk.

movie shows the new gas vent which opened yesterday on the floor of the cavity in Halema`uma`u. Following this reawakening, very faint glow was observed last night for the first time since July 4

The ongoing eruption in Halema'uma'u Crater at the summit of Kilauea Volcano has experienced several significant interruptions in activity since it began in March 2008. The latest disruption began on June 30, 2009, when a large collapse of the vent rim dumped rubble onto the lava surface and dramatically reduced gas emissions.

Status of efforts to restore the Salton Sea

movie shows the lava surface deep within the Halema`uma`u cavity. The lava surface is relatively sluggish, with little movement and only one spattering source.

movie shows a source of minor spattering at the margin of the ponded lava surface within the Halema`uma`u cavity. Weak sloshing of the lava surface can be seen around the spattering source.

movie shows the lava surface within the cavity at Halema`uma`u. Keeping an eye on the lower left portion of the screen, one can see a large rock impacting the lava surface. This impact appears to trigger degassing and overturning that migrates across a large portion of the lava surface.

movie shows activity of the lava surface deep within the Halema`uma`u cavity. The crusted lava surface is moving slowly from northeast to southwest, with occasional bursts of spatter from the margins and cracks.
