Another 2.8 aftershock was felt 5 min ago. A list of all felt aftershocks larger than M2.5 can be found in the list below this article.

Update 13:58 UTC (6:58 local time)
USGS has downgraded the aftershock to Magnitude 3.8.

Update 13:51 UTC (6:51 local time)
A rather strong aftershock of magnitude 3.9 was felt few minutes ago. This followed an rather intense sequence of minor aftershocks. Another M2.8 quake was detected just one minute later

A moderate M4.2 earthquake was felt in most parts of the Los Angeles area on thursday. The quake was centered in San Fernando, abour 32 kilometers north of Los Angeles. Although the quake occurred in a shallow depth of only 8 kilometers, no damage is expected!

The epicenter was located very close to the epicenter of the Northridge quake 1994, but likely originated from another fault. USGS calculated a strike-slip focal mechanism.

Several minor aftershocks have been detected within the first minutes, some of them weakly felt in the direct vicinity of the epicenter.
