Debris flow in Glenwood Canyon during the summer of 2021. This event followed the 2020 Grizzly Creek Fire in Glenwood Canyon, Colorado. 

Interstate 70 in Glenwood Canyon, Colorado. In the summer of 2021, travelers in Colorado's Glenwood Canyon were safely evacuated before massive debris flows buried highways and destroyed bridges, thanks to a debris flow warning system developed in part by the U.S. Geological Survey.

Seismicity of Hawaii: earthquakes M>5 from the 1840-1899, 1900-1959, 1960-2019 catalogs shown separately. While earthquake activity remains high today, it seems to have decreased over the past 60 years, which could be related to less volcanic activity at Mauna Loa.

Landsat 9 is the latest in a prestigious line of satellites that have been watching our planet for nearly 50 years. They have monitored changes on land and made that information freely available to users around the world.

To adapt to rising sea levels, coastal wetlands can migrate landward at the expense of adjacent freshwater wetlands and upland ecosystems, but migration can be hindered by natural and anthropogenic barriers. This photo shows marsh migration constrained by topographic and urban barriers in southern California.

USGS gaging station on the Kenduskeag Stream near Bangor, Maine, station 01037000. This station is downstream of Six Mile Falls, a popular spot during the Kenduskeag Canoe Race.

Landsat's thermal and infrared bands also expose the Caldor fire's advancing edge at night time. This image is from August 29, 201, 15 days after ignition.

The Caldor Fire in California started on August 14, 2021 and quickly spread in high winds. The fire expanded toward the Lake Tahoe area as residents evacuated. Landsat image was captured on August 21, the 8th day. Landsat 8's near-infrared and shortwave infrared bands reveal active fire, burn scars, and smoke.

Dixie Fire The Dixie Fire has become the largest single fire in California's recorded history. State fire officials don't list it at the top, however. The record is held by the massive August Complex Fire of 2020 which burned over one million acres. The term "complex" is used when multiple fires in the same area ignite separately.
