Three relatively small earthquakes occurred on the Hayward Fault in the early hours of Saturday October 22 — all of them centered in the Claremont neighborhood of Berkeley. This follows the series of four that rattled Berkeleyans on Thursday.
The first tremblor happened at 12.06 am and was a magnitude 2.8, according to the USGS, with a depth of five miles. The epicenter was near Tunnel Road not far from where Thursday’s quakes were centered.
A 1.3-magnitude quake followed swiftly at 12:14 a.m, with its epicenter at The Plaza Drive, also in the Claremont neighborhood; and a third one, listed as 2.5 magnitude, at 12:45 a.m, was also just off Tunnel Road, between The Uplands and El Camino Real.
