U.S. Geological Survey awards $4 million grant to UC Berkeley and its research partners to ramp up ShakeAlert prototype.

Architecture and urban design chair Hitoshi Abe is designing homes that will rise from the rubble in his quake- and tsunami-damaged hometown in Japan.

Borehole seismometers will monitor faint tremors beneath the San Andreas Fault — part of UC Berkeley’s TremorScope project to determine the link between tremors and earthquakes.

Seismologists have proven that the Hayward and Calaveras faults are essentially the same system, meaning that a rupture on one could trigger a rupture on the other, producing considerably larger quakes than once thought.

Video, photos, interviews and mapping tools capture the extent of damage four years after the 2011 quake and tsunami.

New sources of information fuel both knowledge and emergency response.

Scientists at the Berkeley Seismological Laboratory were alerted moments before Sunday morning's 6.0 magnitude temblor, courtesy of the ShakeAlert earthquake early-warning system.

Sediment cores collected in 1960s for doctoral thesis have attracted renewed scrutiny for clues to Cascadia earthquakes.

Kelp Watch 2014, a project that tests kelp along the western U.S. coast for signs of radioactive seawater, has found none from the 2011 disaster.
