Brown plume event within the Halema`uma`u vent cavity

movie shows a brown plume event resulting from a collapse within the Halema`uma`u vent cavity. Later views into the vent cavity with a thermal camera revealed that the floor of the vent cavity—at about 200 yards below the vent rim—had fallen away, deepening the vent cavity even further.

Thermal movie showing a view inside the Halema`uma`u vent cavity

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. The 3:13am explosion originated from one of the

Explosion from the vent in Halema`uma`u

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.

Plants at Kahuku unit in Hawai‘i Volcanoes National Park

A myriad of plants can be seen from above in this photograph taken at the Kahuku Unit of Hawai‘i Volcanoes National Park. Acquired in 2009, the Kahuku Unit of Hawai‘i Volcanoes National Park has been an area that multiple USGS PIERC researchers study in, including Dr. Steven C. Hess who studies invasive

Two degassing holes on the floor of Halema`uma`u

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 first half of the movie is shown in normal mode, with the

Halema`uma`u changing of the typical white to dusty brown plume

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.

Actual speed Quicktime movie showing TEB lava stream through skylight

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.

Thermal video showing the new gas vent in Halema`uma`u cavity

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

Halema`uma`u showing the lava surface deep within the cavity850

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.

Halema`uma`u showing spattering, sloshing at the ponded lava surface

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.

Lava surface within the cavity of Halema`uma`u

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.

Eruption cloud, Anatahan Volcano

The eruption of Anatahan Volcano in the Commonwealth of the Northern Mariana Islands (CNMI) continues. It has generated much interest in the volcanologic community and among the residents of Saipan and Guam. It has, unfortunately, also generated exaggerated accounts on the Internet.

Lake Waiau, at an altitude of 3,969 m (13,020 ft) atop Mauna Kea, is the only alpine lake in the Hawaiian island chain. It is thought to have formed at the end of the last glacial retreat, which in Hawai`i was almost complete by 15,000 years ago.

Gushing breakout below Full Strawberry Moon

June 12, 2003

For the past couple of weeks, Kīlauea had presented us with a flurry of tiny earthquakes located at a shallow depth beneath the volcano's summit. The exact cause of this cataract of miniscule events is unknown, but one possibility that comes to mind is expanding gas bubbles trying to escape from the summit magma reservoir.
