EARTH Magazine: Old photos help scientists relocate 1906 San Francisco quake rupture point

Alexandria, VA – Geoscientists using every resource available to them — from bare-earth LIDAR technology to knowledge of turn-of-the-century fashion — have helped correct a 100-year-old mistake about where the San Andreas Fault rupture point was for the historic 1906 earthquake.

DOE report on U.S. Energy Sector Vulnerabilities to Climate Change and Extreme Weather

The Department of Energy updated a report as part of the Administration’s efforts to support national climate change adaptation planning and to promote energy security. The report examines the impacts of climate change and extreme weather on the U.S. energy sector and identifies activities underway to address these challenges as well as potential opportunities to enhance energy technologies.

Distant Quakes Trigger Tremors at U.S. Waste-Injection Sites

A recent study done by Columbia University and the University of Oklahoma published in the 12 July 2013 issue of Science suggests that large (magnitude 7 or above) earthquakes from all over the globe can trigger smaller quakes at waste fluid injection sites where pressure from the fluids has pushed faults close to failure. At some injection locations, a swarm of remotely triggered earthquakes appears to act as a warning sign that large earthquakes related to human activities may be imminent. Several areas in Oklahoma, Colorado, and Texas showed this correlation.
