    NAPA, Calif. (AP) — The largest earthquake to hit the San Francisco Bay Area in 25 years sent scores of people to hospitals, ignited fires, damaged multiple historic buildings and knocked out power to tens of thousands on Sunday. The 6.0-magnitude earthquake that struck just before 3:30 a.m. miles from Napa in California wine country was felt widely, breaking water mains, causing more than 100 gas leaks, leaving two adults and a child critically injured, damaging some of Napa Valley's famed wineries, and sending residents running out of their homes in the darkness.

    ...the study provides the strongest evidence yet that the upsurge quakes in the past decade across Central and mid-America is at least partially to be blamed on humans. More than 300 earthquakes have occurred from 2010 to 2012 compared to an average rate of 21 every year from 1967 to 2000, according to the U.S. Geological Survey. Most have ranged from 2.0 to 3.6 on the Richter scale but there have been exceptions, including a 5.6 event in central Oklahoma in November 2011 that destroyed 14 homes and injured two people.

    California's San Francisco Bay Area grew into a metropolis during the eerily quiet earthquake gap following its devastating 1906 temblor. Scientists predict a 63 percent chance of another big quake before 2032, but when the shaking starts, it may not be a single "Big One" as in 1906, according to a new study. Instead, the Bay Area could face a cluster of deadly earthquakes that deliver a series of rapid punches, researchers report today (May 19) in the Bulletin of the Seismological Society of America. ....

It’s not a question of if the San Andreas fault ruptures in Southern California, but when. […] Seismologists at the US Geological Survey have simulated the effects of the next big Californian earthquake in a program of study called ShakeOut. One of their computer models assumes that the next big event on the San Andreas fault will be magnitude 7.8, with a single event in which a rupture starts in Southern California near the Salton Sea and then shoots north along the fault to hit...

Fishermen in Japan reported a sharp uptick in oarfish sightings in March 2010 following the massive magnitude-8.8 earthquake in Chile that same month, which marked almost exactly one year before the country was devastated by its own magnitude-8.9 quake in northeast Japan.

    For decades, scientists have assumed the central portion of California’s San Andreas fault acts as a barrier that prevents a big quake in the southern part of the state from spreading to the north, and vice versa. As a result, a mega-quake that could be felt from San Diego to San Francisco was widely considered impossible. But that key fault segment might not serve as a barrier in all cases, researchers wrote Wednesday in the online edition of the journal Nature. Using a combination of laboratory measurements and computer simulations, the two scientists showed how so-called creeping segments in a...

    Geologists say Jesus, as described in the New Testament, was most likely crucified on Friday, April 3, in the year 33. The latest investigation, reported in International Geology Review, focused on earthquake activity at the Dead Sea, located 13 miles from Jerusalem. The Gospel of Matthew, Chapter 27, mentions that an earthquake coincided with the crucifixion: “And when Jesus had cried out again in a loud voice, he gave up his spirit. At that moment the curtain of the temple was torn in two from top to bottom. The earth shook, the rocks split and the tombs broke open.”
