Magnitude 4.4 Earthquake Shakes the Bay Area: USGS

07 January 2018

A strong natural disaster woke up the Bay Area Thursday morning and residents took to Twitter to react.

The quake struck around 2:39 a.m. about two miles east from Berkeley, just across the bay from San Francisco, according to the U.S. Geological Survey.

He also said there were no reports of any damage or injuries.

"Looking historically at all the earthquakes that have happened in California, about 5 percent of the time earthquakes are followed by larger earthquakes", he said. The first data from the USGS measured the quake at Magnitude 4.7.

The USGS acknowledged though that the natural disaster was relatively deep for a Hayward Fault quake. It wouldn't be a big surprise if we had a big natural disaster on the Hayward Fault.

There hasn't been a major natural disaster on the Hayward Fault in over 100 years.

Interim San Francisco Mayor London Breed advised residents of the city that "there is no tsunami expected and departments are working on preliminary damage reports". It killed 30 people, caused widespread destruction and was one of the most destructive in California history.

The quake appears to have happened on the Hayward Fault which is becoming due for a large natural disaster. It's been 150 years since the last rupture. A 2003 report determined that the Hayward-Rodgers Creek fault system would produce at least a magnitude 6.7 natural disaster in the next 30 years.

The natural disaster hit the San Francisco area about 2.40am local time (11.40pm NZT) and lasted about 10 seconds, causing a "little bit of rolling motion and a sharp jolt", NBC Bay Area Chief Meteorologist Jeff Ranieri wrote on Twitter. But a video posted to Twitter showed products that had fallen from the shelves of a San Leandro Safeway store.

USGS officials said that usually older structures suffer more damage in earthquakes.
