Image of the Week: Batagaika Crater and the Megaslump
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.

Lava Lake at Kīlauea's Summit
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.

UAS Video, July 19, 2017, of the Mud Creek Landslide in Big Sur
The Mud Creek landslide on Big Sur coast, California, occurred on May 20, 2017. USGS Mendenhall researcher Shawn Harrison took this video from an unmanned aerial system (UAS) on July 19, 2017. USGS drone footage shows the slide from many angles.

Debris flow monitoring at Chalk Cliffs, CO (2017)
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.

Pāhoehoe Breakout
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.

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

Pāhoehoe Breakout on Coastal Plain
This video shows the recent pähoehoe breakout along the 61g lava flow on the coastal plain. The first few segments are shown at x30 speed and the final segment is a time-lapse over 10 minutes with a frame every 30 seconds

Time-lapse sequence of lava delta subsidence at ocean entry
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.

Wildlife on the Nevada National Security Site
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.

Return of the Yellowstone Grizzly Bear
Yellowstone grizzly bears inhabit federal, state, tribal, and private lands, and long-term research requires careful coordination across governmental levels.
