So, the little earthquakes are getting bigger? It means nothing. It's just the 30th anniversary of Loma Prieta. Pure coincidence.
A 4.5-magnitude quake with an epicenter in Pleasant Hill struck at 10:33 p.m. and jiggled San Francisco for a good few seconds. An initial magnitude estimate from from the USGS had it at 4.7M, but that has been downgraded.
KTVU is reporting they've gotten a lot of calls, but no reports of damage besides some pictures falling off walls in the East Bay.
This quake follows on a couple of small ones Sunday evening centered near Morgan Hill, and a 3.5M quake a week ago Saturday that was felt in SF, centered off the coast, a few miles west-southwest of Colma.
The shaker has prompted an earthquake kit warning from Scott Wiener.
And I'm not going to get into foreshocks and earthquake science, which is still in its infancy. But I'll just leave this here.

Small earthquake in San Francisco just now. Another reminder to prepare. The Big One is coming at some point. Some info: https://t.co/51EM8YqBzf

Breaking (and shaking): That was a 4.7 #earthquake, centered near Pleasant Hill in Contra Costa County, but felt all the way to San Francisco. 3 days before the 30th anniversary of Loma Prieta!
