Latest San Andreas Fault Stories
Most earthquakes occur along fault lines, which form boundaries between two tectonic plates.
Using a technique normally used for detecting weak tremors, scientists at the Georgia Institute of Technology discovered that the 2004 magnitude 6 earthquake along the Parkfield section of the San Andreas fault exhibited almost 11 times more aftershocks than previously thought.
With an average of four mini-earthquakes per day, Southern California's San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the Southern San Andreas fault, according to an article in the journal Nature Geoscience.
Scientists say many recent earthquakes might have been the aftershocks of large quakes that occurred hundreds of years ago.
Researchers at the Carnegie Institution say that they have discovered a method of measuring and monitoring geological fault lines beneath the Earthâ€™s crustâ€”a development that could significantly enhance scientistsâ€™ ability to accurately predict earthquakes.
New Zealand is the site of one of the world's youngest subduction zones, where the Pacific Plate of Earth's crust dives beneath the Australian Plate
Tremors deep within the San Andreas Fault suggest California should not become complacent about future earthquakes, a leading seismologist said. The San Andreas fault is changing down deep and it's changing down deep in places where large earthquakes have happened in the past, said Robert Nadeau, a research seismologist at the University of California, Berkeley. Seismic activity in the central part of the fault has increased in the years since the magnitude 6.5 San Simeon quake in 2003 and...
A spike in mysterious underground rumblings observed on a section of the San Andreas fault near Parkfield, California, could indicate a build-up of stress and an increased likelihood of a major earthquake.
When a swarm of hundreds of small to moderate earthquakes erupted beneath California's Salton Sea in March, sending spasms rumbling across the desert floor, it set off more than just seismometers.
