East Bay residents got a jolt on Saturday morning. And then another one. And then another one. And then another one. 

Four different earthquakes hit near San Leandro, a suburban city bordering Oakland, within a 40 minute span on Saturday morning. 

The first quake struck at 9:24 a.m. with a preliminary magnitude of 3.2. Two more 3.2-magnitude jolts, separated by just 15 seconds, followed at 9:43 a.m. A 2.2 earthquake at 10:02 a.m. rounded out the quartet. The depths of the earthquakes ranged from 4.26 to 4.63 miles.

KRON4 News said that residents as far away as Martinez reported feeling the shakes. 

The quakes were not far from the Oakland Zoo, prompting one Twitter user to joke that he couldn’t tell if it was an earthquake or a “giant gorilla party.”

Another noted that the string of quakes felt like an all-too-serious April Fools joke.

There were no initial reports of injuries or major damage.
