The quake was felt as far away as Lancaster, Laguna Niguel, Rancho Cucamonga and Ventura, according to the USGS. The M4.0 that just happened was under Lennox, CA, near Inglewood. Very deep at 20 km, so everyone is at least 20 km away. Would have been felt by most people awake in LA. Movement was thrust, probably not on any mapped fault https://t.co/UIPbVH0kw5 — Dr. Lucy Jones (@DrLucyJones) April 5, 2021 The temblor was preceded by a pair of quakes, registering 3.3 and 2.5, by about 30 minutes.
