BREAKING NEWS: 5.6 quake biggest since Loma Prieta

From the Santa Cruz Sentinel

SANTA CRUZ — A moderate earthquake rattled the region Tuesday night, startling county residents, sending moviegoers from theaters and drinkers from bars, but apparently doing little serious damage.
The 8:04 p.m. quake on the Calaveras Fault had a preliminary magnitude of 5.6, according to the U.S. Geological Survey. It was centered in the foothills about nine miles east of San Jose City Hall, and originated 5.7 miles below ground.
There were no reports of damage or injuries in Santa Clara County. Acting Santa Cruz Fire Battalion Chief Rob Young said the county checked out clean as well, though cellular and landline phone service was temporarily disrupted.
The temblor, which shook for roughly 30 seconds, was the most powerful quake to hit the San Francisco Bay Area since Loma Prieta on Oct. 17, 1989, according to the USGS. In the 6.9-magnitude quake, six people were killed locally, more than 300 were injured and an estimated 3,000 were left homeless. Damage in Santa Cruz County was estimated at close to $1 billion. Throughout the region it killed 62 people and caused $6 billion in damage.
Tuesday night’s shaker brought the 18-year-old Santa Cruz Mountains earthquake back to life for many Santa Cruz residents.
“There’s something about the month of October,” said Jeff Pappas, a bartender who ran from behind his bar at Clouds Downtown just in case the glass behind him came tumbling down. “This is the biggest one I’ve felt since Loma Prieta.”
