Join USGS researchers Jason Chaytor and Kira Mizell as they virtually participate in a NOAA Ocean Exploration expedition to the depths of the North Atlantic.

The eruption in Halema`uma`u crater, at the summit of Kilauea, is no longer active. The lava lake that was active between December 2020 and May 2021 remains solidified at the surface. A routine summit overflight observed no signs of residual incandescence in cracks, and only a diffuse gas plume rising from the northern portion of the lake.
 

Yellowstone Volcano Observatory scientist-in-charge Mike Poland provides the YVO monthly update from the rim of Yellowstone’s Grand Canyon. The V-shaped gorge tells an amazing geologic story. About half a million years ago, a large rhyolite lava flow erupted. Over time, hot water and gases heated by the magma chamber rose through faults in the lava flow.

This video shows a typical day on Mauna Loa, captured from a new webcam looking south towards the volcano. The field of view covers the summit region and much of the Northeast Rift Zone.

The area of active surface lava has diminished over the past month in Halema`uma`u crater, at the summit of Kilauea. Today, active surface lava was limited to a small pond, about 20 meters (yards) long. The pond surface was normally covered with a stationary crust, but occasionally resurfaced. This video shows crustal foundering during a resurfacing event.

The lava lake in Halemaʻumaʻu crater, at the summit of Kīlauea, remains active but has diminished in area and vigor over the past month. This thermal timelapse sequence shows the changes in the lake activity over the past month. In mid-April the area of active surface lava in the lake was approximately 7.5 acres (3 hectares).

Jon Major, scientist-in-charge of the USGS Cascades Volcano Observatory, provides an overview of the major volcano hazards in the Cascades, the function and responsibilities of the Cascades Volcano Observatory, and a brief synopsis of what's been going on at Mount Baker, Glacier Peak, Mount Rainier, Mount Adams, Mount St.

It's May, the snow is melting and the roads are mostly open, so it's time for geologists, geophysicist and geochemists to head into Yellowstone to start projects they have been planning for the last several months. Next week, a field team will deploy a temporary GPS network to help “densify” the network of continuous GPS stations already in place.

The 1980 eruption of Mount St. Helens was monumental in so many different ways. It had a huge impact on the geography of southwestern Washington, ash affected many people, lives were lost, and lessons were learned. The eruption also led to the creation of the USGS Cascades Volcano Observatory in Vancouver, Washington.

The lava lake in Halema‘uma‘u Crater, at the summit of Kīlauea Volcano, remains active. This video is shown at 30x speed and shows the lava supplying the lake from the western fissure, with scattered crustal foundering across the lake surface.

Hawaiian Volcano Observatory geologists conducted a routine helicopter overflight of the lava lake in Halema‘uma‘u Crater, at the summit of Kīlauea. Active surface lava remains limited to a small area in the western portion of the lake, with the eastern portion solidified at the surface.

Hawaiian Volcano Observatory geologists visited the east rim of Halema‘uma‘u Crater to make observations of Kīlauea's summit lava lake and survey the eastern portion of the crater. This video compilation shows different aspects of the lake activity in the western portion of the crater. 

This video shows the inlet along the western margin of the lava lake in Halema‘uma‘u Crater, at the summit of Kīlauea. The lava stream was moving slowly but steadily, and was emerging beneath a portion of crust attached to the lake margin. The video is shown at 10x speed.
 

KPcam webcam on the flank of Mauna Loa looks south towards the summit of Kīlauea to monitor the gas plume from the active lava lake. This time-lapse video shows a typical day for the summit plume. Clear views in the night and morning show the low, ground-hugging plume carried to the southwest by the tradewinds.
