Media Advisory: Earthquake Country Alliance at USGS
Members of the news media are invited to attend the next Earthquake Country Alliance - Bay Area Regional Workshop to be held at the U.S. Geological Survey in Menlo Park on May 23. ECA workshops are educational and informational opportunities to learn more about the latest in earthquake science, preparedness, and mitigation, as well as to arrange interviews with subject matter experts.
Enormous Caribbean Waves Before 1492
Geologists have discovered evidence that unusual seas detached living corals from a Caribbean reef and scattered them far inland, as boulders, during the last centuries before Columbus arrived. The new findings will reinforce precautions against coastal hazards, Caribbean tsunami specialists said.
Photo Opportunity: Scientists Prepare for Seismic Study in East Bay
MEDIA ADVISORY: Faculty and students from California State University, East Bay, U.S. Geological Survey scientists, and community volunteers are conducting an experiment to visualize the subsurface in and around the Hayward Fault and measure how the ground in different neighborhoods responds to earthquake shaking.

Rodgers Creek Fault Traced through Santa Rosa
For the first time, scientists at the U.S. Geological Survey have mapped the active surface trace of the Rodgers Creek Fault through the central part of the northern California city of Santa Rosa. Urban development has, until now, obscured its exact location.
Media Advisory and Photo Op: USGS Employees Get Ready to “Drop, Cover, and Hold On!” in the Great ShakeOut
MENLO PARK, Calif. — U.S. Geological Survey employees in Menlo Park, Calif. will participate in an earthquake safety drill, and test their emergency response plan as part of the Great ShakeOut on Oct. 15, an annual day of action to practice how to protect yourself from an earthquake.
Megathrust Quake Faults Weaker and Less Stressed than Thought
MENLO PARK, Calif. — Some of the inner workings of Earth’s subduction zones and their “megathrust” faults are revealed in a paper published today in the journal “Science.” U.S. Geological Survey scientist Jeanne Hardebeck calculated the frictional strength of subduction zone faults worldwide, and the stresses they are under.
Media Advisory: Yes, Humans Really Are Causing Earthquakes — Public Lecture
The earthquake rate has dramatically increased in the central United States in the last six years. Oklahoma had more magnitude 3 or greater earthquakes in 2014 than California.
Researchers Test Smartphones for Earthquake Warning
MENLO PARK, Calif.— Smartphones and other personal electronic devices could, in regions where they are in widespread use, function as early warning systems for large earthquakes according to newly reported research.
Earthquake Sensor Installed in New Bay Area Soccer Stadium
Where better to install a new earthquake sensor than in the new home of the San Jose Earthquakes Major League Soccer team?
Coping with Earthquakes Induced by Fluid Injection
MENLO PARK, Calif.— A paper published today in Science provides a case for increasing transparency and data collection to enable strategies for mitigating the effects of human-induced earthquakes caused by wastewater injection associated with oil and gas production in the United States.
