A Possible Cause of Earthquakes in the Continental Interior
Release Date: JUNE 18, 2018 A new map of crustal stress across the U.S. shows that the plate interior stress is variable, with contributions from plate boundary stress, crustal collapse due to gravity, and more local and subtle changes to style, orientation, and earthquake rate.
Mountain Permafrost, Climate Change, and Rock Avalanches in Glacier Bay National Park, Alaska
Release Date: JUNE 18, 2018 We usually hear about landslides and avalanches that are caused by large amounts of rainfall, the shaking from earthquakes, or a volcanic eruption, but we may be hearing more about avalanches caused by the (seemingly innocuous) melting of ice in the coming years.
Slow-Motion Landslides
Release Date: JUNE 11, 2018 Sluggishly-moving earthflows can help us learn what controls the starting and stopping of landslides.
Landslides Can Cause More Landslides
Release Date: MAY 15, 2018 The deadliest individual landslides in the U.S. recently were in places where there had previously been a landslide. Why do landslides happen in the same place instead of on nearby slopes that appear to be just as likely, if not more likely, to slide?
The Past Holds the Key to the Future of Aftershock Forecasting
Release Date: MAY 7, 2018 The outcomes of past aftershock sequences can be used to describe the range of possibilities for a current sequence.
Untangling Faults at Depth – What Lies Beneath Panamint Valley, California?
Release Date: APRIL 30, 2018 The eastern edge of Panamint Valley,CA has two types of faults that can be seen in the near-surface geology. 150 geophones and a seismic source will help reveal the subsurface picture.
