Lava flows are one of the coolest (or maybe hottest!) features about volcanoes, but what would a lava flow look like if you could peel away the surface and take a peek underneath?

In the Barry Arm fjord of Alaska, repeat, high-resolution aerial and satellite data provide a unique opportunity to learn how a large bedrock landslide with a receding and thinning glacier at the toe is deforming.

Will an earthquake happen where you live? We have the resources that will let you know. Check out the video to learn more. September is National Preparedness Month.

Do you know what a “go” bag is? Does your family have a plan in case of an emergency? Check out the video to see what you can do to get yourself prepared if there were an earthquake. 

Earthquakes can affect millions of people across the United States. But do you know what causes them? This video will tell you.

September is National Preparedness Month. Learn more about the natural hazards you may face in our feature story.

The new eruption at the summit of Kīlauea volcano continues. Numerous fountains remain active on the downdropped block east of Halema‘uma‘u crater, with lava pouring west onto the crater floor.

During the morning of September 11, Hawaiian Volcano Observatory geologists conducted an overflight of the new eruption within the Kīlauea summit caldera. The eruption is occurring in the east portion of Halemaʻumaʻu crater and on the downdropped block to the east, which formed during the 2018 summit collapse.

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.

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.

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.
