Another eruption at the summit of Kīlauea volcano began at 3:13 p.m. on September 10, 2023. This video, captured by the Hawaiian Volcano Observatory's B2cam on the east rim of Halemaʻumaʻu crater, shows the opening phase of the eruption. A lava fountain bursts from a degassing area in the eastern portion of Halemaʻumaʻu crater.

The B1cam, located on the east margin of the down-dropped block within Kīlauea caldera, captured the start of another eruption at the summit of Kīlauea volcano that began at 3:13 p.m. on September 10, 2023. This video shows a lava fountain bursting from a degassing area in the eastern portion of Halemaʻumaʻu crater, with the downdropped block in the foreground.

This video, captured the evening of September 10, 2023, from near the Uēkahuna overlook within Hawai'i Volcanoes National Park, shows the new eruption within Kīlauea caldera. After approximately an hour of elevated earthquake and ground deformation, the eruption began at 3:13 p.m. on September 10, 2023.

Natural hazards are unavoidable. But with proper preparedness, their impact can be reduced. The USGS and its partners work to prepare, monitor, assess, and alert people to the hazards around them. Are you ready if you're affected by a disaster?   

What geologic hazard is most likely to occur in the Yellowstone region on human timescales? The answer might not be what you think.

How debris flows erode and deposit material along their paths is difficult to determine in natural settings due to the lack of warning and the rapid pace at which they occur. Post-event field measurements or controlled flume experiments are commonly used to evaluate debris flows between the head and the distalmost deposit.

Geysers and hot springs are some of the most dynamic geologic features on the planet. They are always changing and sometimes that change happens in places where we can see and appreciate it. This has been the case on Geyser Hill, near Old Faithful, in Yellowstone National Park.

The ocean is a beautiful, dynamic, and sometimes dangerous place. Unsurprisingly, this is probably why a lot of USGS researchers spend their entire careers studying it. In celebration of National Ocean Month, we thought it would be a good time to dive in and feature ten ocean field sites you’ve got to “sea” to believe.

Old Faithful, one of the icons of Yellowstone National Park and probably the most famous geyser in the world. But how faithful is it really? That's the question we're going to tackle in this June 1, 2023 update from the Yellowstone Volcano Observatory.

A routine helicopter overflight provided aerial views of Halema‘uma‘u crater, at the summit of Kīlauea. The crater floor is covered by solidified lava erupted during the previous summit eruption, earlier this year. Inflation and seismic activity in the summit region indicate ongoing unrest.

The Washington Geological Survey works to increase public and scientific understanding of landslide hazards in Washington State. One of the ways that we do this is through use of interpretive maps, illustrations, and other types of graphics. I will show several examples of these products and will discuss some of the methods used to construct them.

The May 18, 1980, eruption of Mount St. Helens was historic and fundamentally changed how we see volcanoes. For those who lost family and friends, homes, and their livelihoods, it was an unimaginable tragedy. For others around the world, the eruption was an exciting curiosity, an experience they could share with their kids and grandkids.

May is Volcano Awareness Month in Washington State. There's no better time to learn five incredible facts about Mount St. Helens. This list is a truncated version of the popular 30 Cool Facts about Mount St. Helens (usgs.gov) poster.

May is traditionally the start of the field season and plans are underway to strengthen monitoring networks, collect data, and conduct research to better understand volcanic activity in the Yellowstone region. Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, outlines upcoming projects in this YVO monthly video update for May 1, 2023.
