Originally listed as a pretty epic 3.9, the US Geological Survey has since downgraded Saturday morning’s tremor to a still-impressive 3.5 magnitude.  

Many of us sleep past 8:41 a.m. on a Saturday, but not today. Our collective sleep-ins and hangovers were interrupted by what the US Geological Service describes a 3.5 magnitude earthquake, according to KGO. The epicenter was listed as “3.73mi WSW of Colma, CA”

The quake was originally listed as a 3.9 magnitude quake, but the USGS quickly downgraded it to a 3.5.

No damage has been reported yet, so it preliminarily seems like we got off easy. But do prepare for aftershocks, and of course, make sure you have a disaster preparedness go-bag.
