Balloon fleet senses earthquakes from stratosphere

A new study in AGU's Geophysical Research Letters reports on the first detection of a large, distant earthquake in a network of balloon-bound pressure sensors in the stratosphere. The technique could one day be applied on ...

Understanding earthquakes triggered by wastewater injection

Since 2009, many central U.S. residents have faced increasing earthquake activity. Research has suggested that these tremors are linked to wastewater injection into deep wells by oil and gas companies. However, the precise ...

New model may improve Bay Area seismic hazard maps

The Santa Cruz Mountains define the geography of the Bay Area south of San Francisco, protecting the peninsula from the Pacific Ocean's cold marine layer and forming the region's notorious microclimates. The range also represents ...

Ridgecrest shows how earthquakes damage Earth's crust

In July 2019, a series of earthquakes including two major shocks of magnitude 6.4 and 7.1 a day apart struck near Ridgecrest, CA, between Los Angeles and Las Vegas. For local residents, it was a violent interruption to the ...

Comparing machine learning models for earthquake detection

Machine learning is transforming data-heavy fields across the sciences, and seismology is no exception. Several machine learning methods have emerged for earthquake detection, phase identification, and phase picking. However, ...

Using sparse data to predict lab quakes

A machine-learning approach developed for sparse data reliably predicts fault slip in laboratory earthquakes and could be key to predicting fault slip and potentially earthquakes in the field. The research by a Los Alamos ...

New type of earthquake discovered

A Canadian-German research team have documented a new type of earthquake in an injection environment in British Columbia, Canada. Unlike conventional earthquakes of the same magnitude, they are slower and last longer. The ...
