3.4 Magnitude Earthquake in Port Hueneme

An earthquake with a preliminary magnitude of 3.5 struck 7 miles west southwest of Port Hueneme in Ventura County early Wednesday morning, the U.S. Geological Survey said.

The quake struck at 4:44 a.m. and had a depth of 0.7 miles.

Observer readers in Ventura and Oxnard reported feeling the temblor. There were no immediate reports of damage or injuries.

Interestingly, the quake comes at the same time that a volcano in Mexico erupted, 400 miles to the south of the Santa Clarita earthquake's epicenter. It was not clear other the two events are related.

The volcano had a relatively strong explosion yesterday evening at 20:31 local time. It produced a 2 km ash column and ejected incandescent fragments that landed in to up to 3.5 km distance on the eastern and southeastern flanks, igniting some bush fires on the upper slopes of the volcano.
