Damaging Sichuan earthquakes linked to fracking operations

Two moderate-sized earthquakes that struck the southern Sichuan Province of China last December and January were probably caused by nearby fracking operations, according to...

Crowdsourcing speeds up earthquake monitoring

Data produced by internet users can help to speed up the detection of earthquakes. Fast and accurate information is essential in the case of...

California’s current earthquake hiatus is an unlikely pause

There have been no major ground rupturing earthquakes along California's three highest slip rate faults in the past 100 years. A new study published...

Signs of 1906 earthquake revealed in mapping of offshore northern San...

A new high-resolution map of a poorly known section of the northern San Andreas Fault reveals signs of the 1906 San Francisco earthquake, and...

Massive earthquakes provide new insight into deep Earth

In the waning months of 2018, two of the mightiest deep earthquakes ever recorded in human history rattled the Tonga-Fiji region of the South...

Hundreds of bubble streams link biology, seismology off Washington’s coast

Off the coast of Washington, columns of bubbles rise from the seafloor, as if evidence of a sleeping dragon lying below. But these bubbles...

A new way to sense earthquakes could help improve early warning...

Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could...

Fast, simple new assessment of earthquake hazard

Geophysicists at Caltech have created a new method for determining earthquake hazards by measuring how fast energy is building up on faults in a...

Seemingly dormant geologic fault damaged famous Roman buildings 1,500 years ago
