Spattering is common in Kīlauea Volcano's summit lava lake, and consists of many large bursting gas bubbles. The fluid nature of the lake can be seen when lava hits the wall and flows downward like syrup. The thin, flexible nature of the crust is also shown here, as the bursting gas bubbles rip and fold the thin skin on the lake.

Image of the Week: Hurricane Harvey Flooding
Hurricane Harvey dumped over 50 inches of rain near Houston, leaving extensive flooding throughout the area.
At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.

Excavating the Teton Trench September 2017 - Day 2
USGS scientists Rich Briggs, Ryan Gold, Chris DuRoss, and Jaime Delano spent September 5-21, 2017 outside of Jackson, Wyoming doing fieldwork at a site to collect paleoseismology data on a segment of the Teton Fault. This video shows the second day of the site excavation inside the flagged the boundaries set up by the group.

Shatter Ring on Kamokuna Lava Delta
A shatter ring forms and grows on the Kamokuna lava delta. This video shows repeated uplift and subsidence of the delta surface by the lava supply under the surface. This process creates a large round rubble pile, called a shatter ring.
