An earthquake of magnitude 4.6 in Northern California awakened residents with a jolt early Thursday, with many saying they felt their homes shake for a few seconds in a 161-kilometre stretch, including San Francisco. Boulder Creek, which has about 5,000 people, is about 105 kilometres southeast of San Francisco. Residents as far north as Petaluma, about 64 kilometres north of San Francisco, also said they felt it. Some residents said they were first awakened by earthquake alerts on their phone, then felt their beds and windows shake. The area east of San Francisco has experienced earthquake swarms - when multiple small magnitude earthquakes strike over a short period of time - for decades, according to seismology experts.
