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.
The next earthquake in the Napa Valley could be much stronger than the magnitude 6 quake that shook the region in August, according to preliminary research from the University of California at Davis.
The project includes 39-story and 35-story skyscrapers that would dwarf existing buildings.
A earthquake registering a preliminary magnitude of 4.0 struck near Mammoth Lakes Sunday, according to the U.S. Geological Survey’s automated seismograph alert network.
Seismologists at the Lawrence Livermore Lab will use their supercomputers to simulate detailed ground motion from last month’s earthquake in Napa.
