A UC Riverside scientist is studying a previously unknown fault underlying the two large earthquakes that shook the town of Ridgecrest in July.

Dr. Abhijit Ghosh is an associate professor of geophysics at UCR.

On July 6, just a day after the 7.1 earthquake in Ridgecrest, Ghosh drove out to the city to install 25 seismometers in the ground.

Seismometers are instruments that measure vibrations in the ground and record them into a data log that can be used to analyze earthquakes.
