Two Recent Earthquakes Shake California

QuakeFinder is reviewing data from its stations close to two recent earthquakes in California. A magnitude 4.5 quake struck at 10:33pm PDT on Monday, Oct. 14 near our Concord station and the second, a magnitude 4.8 was felt only 14 hours later at 12:42pm on Tuesday, Oct. 15 near our Pinnacles station. Both stations were successfully recording magnetic field data during the earthquakes and in the days leading up to them.

QuakeFinder is studying the magnetic field, searching for reliable pre-seismic signals with the ultimate goal of building an earthquake forecasting system. The data from these quakes will help us better understand the behavior of the magnetic field and further isolate earth-sourced magnetic signatures.
