February 2018 Danville, California Sequence
Mon Mar 5, 7:30pm PT The earthquake swarm near Danville had continued to taper off over the past week. Since Feb 23 there have only been two earthquakes in the sequence larger than magnitude 2.0, a magnitude 2.0 on Feb 27 and a magnitude 2.5 on Mar 1. The most likely scenario looking forward is for this sequence to continue to taper off.
