VENTURA (CBSLA) — For a second day in a row, a series of small earthquakes Friday jolted Ventura starting in the early morning hours and lasting into mid-afternoon.
A magnitude-3 quake was recorded just before 2 p.m. near Ventura, hours after more than at least four small quakes rattled the area – one of which was a magnitude-3.5 earthquake that struck about 4 miles west of Ventura at about 4:10 a.m. Friday.
Shaking was felt in Oxnard, Port Hueneme, Oak View, Santa Paula and Carpinteria in Santa Barbara County, according to the U.S. Geological Survey.
That quake was followed by a 2.9 and a 3.6 that struck at the same time at 5:29 a.m., less than a mile from each other, and a 3.2 that hit at 5:37 a.m. just a little closer to Ventura.
Friday’s quake swarm struck in the same area that was hit by a swarm of earthquakes Thursday. The two biggest of that swarm, a 3.3 and a 3.4, struck at about 5 a.m.
There were no reports of injury or damage.
The quakes are believed to be part of a swarm of 70 quake events that began at 4 p.m. Thursday with a M0.9 temblor, according to earthquake expert Dr. Lucy Jones.
The current Ventura swarm started at 4 pm 11/6 with a M0.9 event.
So far the swarm has had 70 events, with 5 events of M>3.2, and largest M3.6. One interpretation is that this is occurring on an unmapped NNW striking tear fault in the upper block of the Ventura fault. pic.twitter.com/jlZVsnvjMM

Swarms of earthquakes are common and is unlikely to be followed by a bigger temblor, Jones added.
