This morning (2/21/2020) at 5:42 am, a small earthquake struck the Castaic area north of Los Angeles. Just looking at the maps, it seems near the San Gabriel Fault but it is a somewhat complex area. It was also a very deep earthquake as they go, 18.1 km. Shaking was felt in a wide area but wasn’t very strong.
