Warm summers and short winters are thawing permafrost in the Siberian tundra, causing soil erosion. As a result, the 800 meter wide Batagaika crater continues to expand.
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.

- Glacier Numerology – The how big, how long, how thick, how much, how often, of glacier science.
- Glacier Photography – While a picture may be worth a thousand words, a collection of images may tell a complete forensic story.

This video clip shows spattering along the south margin of the summit lava lake. Note the large slab of crust migrating into the spatter site, where it is consumed. Unfortunately, wind noise masks much of the spattering sound in this video.

The USGS and its cooperators have installed debris-flow monitoring equipment in the largest drainage basin at Chalk Cliffs, CO. Data collection at this site supports research on the hydrologic factors that control debris-flow initiation, entrainment, and flow dynamics.

Pähoehoe breakouts remain active on the coastal plain, a short distance from the base of the pali. Typical breakout activity was observed today. This video clip, shown at x30 speed, highlights the erratic nature of pähoehoe advance, and the process of inflation beneath the crust.

The Kamokuna ocean entry remains active. Several parallel cracks cross the delta, suggesting sagaing and instability at the front of the delta.

This movie shows a sequence of 8 time-lapse photos—one photo per day from July 6 to July 13, 2017—of the lava delta at Kīlauea Volcano's Kamokuna ocean entry. The sequence shows the front of the delta subsiding, and cracks running parallel to the coast widening, over the 8-day time period.

Mountain lions, desert bighorn sheep, mule deer, and a variety of other wildlife live on and pass through the Nevada National Security Site each day. It’s a highly restricted area that is free of hunting and has surprisingly pristine areas.This 22-minute program highlights an extraordinary study on how mountain lions interact with their prey.
