An earthquake woke many Berkeleyans shortly after 2:39 a.m. Thursday.
According to early data provided by the US Geological Service, the quake had its epicenter 13 kilometers under Claremont Avenue, just near the Claremont Hotel. Part of the Hayward fault runs along the Berkeley side of the East Bay hills. The first data from the USGS measured the quake at Magnitude 4.7. Within minutes it was downgraded to a 4.5, and by around 9 a.m. it was being reported as a 4.4.
Despite the early hour, local Twitter went momentarily crazy over the quake, many replying to Berkeleyside’s early tweet.

Epicenter looks like it was just under us (back side of Claremont hotel). Needless to say, both kids are in bed with us. That felt big!— 🏳️🌈 Lori Droste (@loridroste) January 4, 2018
.@berkeleyside Long fluttery shaky. And that subliminal sound that you sense before you hear, but you hear before you feel. Could hear the ventilation pipes up to the roof rattling. Nothing fell here. Near Ashby/Telegraph— e_phemera (@e_phemera) January 4, 2018
shake, rattled things off shelf, cat freaked out, mother nature in charge with recent full moon, high tides and uranus station…..— Andrea Mallis (@virgoinservice) January 4, 2018
