The U.S. Geological Survey is reporting an earthquake with a magnitude of 2.8 has struck in Concord.
The Concord fault that shook to the tune of a 3.6 magnitude earthquake Sunday has the potential to do major damage in the East Bay.
The research out of USC suggests that a major earthquake on the San Andreas Fault could trigger large earthquakes on other nearby faults, intensifying the damage over a larger area.
Officials are considering revising tsunami hazard maps after researchers found the Ventura fault line in Southern California is much more dangerous than previously believed.
The U.S. Geological Survey says a magnitude 2.7 earthquake has struck in the north East Bay.
The U.S. Geological Survey says two magnitude 4.0-plus earthquakes have struck on the California-Mexico border.
7.0+ Magnitude Mega-Quake Possible In Berkeley Hills As Seismic Movement Links Calaveras, Hayward Faults
Seismologists now believe the Hayward Fault is actually a branch of the Calaveras Fault, meaning the faults have a much greater destructive potential in the case of a simultaneous rupture, potentially triggering a tremor stronger than the 1989 disaster.
The probability California will experience a magnitude 8 or larger earthquake in the next couple of decades has increased, according to the U.S. Geological Survey.
The U.S. Geological Survey says a 6.9 magnitude earthquake struck in the middle of the Atlantic Ocean Friday morning.
A series of four earthquakes registering a preliminary magnitude range of 1.4 to 2.0 struck near Concord Sunday afternoon and Monday, according to the U.S. Geological Survey’s automated seismograph alert network.
