Jascha Polet @CPPGeophysicsA few little foreshocks and already several aftershocks to M4.5 quake near Pleasant Hill. Based on early aftershock alignment and mechanism, looks like right lateral strike slip (not surprising) near Calaveras and Concord fault zones. https://earthquake.usgs.gov/earthquakes/map pic.twitter.com/Lvkc1rrLYFShow this thread1 reply 1 retweet 4 likesShow this thread
