LAKE PILLSBURY – Another 3.0 earthquake was reported in the Lake Pillsbury area early Saturday morning.

The quake, centered 8 miles west northwest of Lake Pillsbury, occurred at 6:28 a.m. at a depth of less than a mile, according to the US Geological Survey.

That's the third earthquake of 3.0 magnitude or greater to occur in the area this week, and the sixth this month, according to US Geological Survey records.

April has been an active month seismically for the Pillsbury area. In all, about 90 quakes of various sizes have occurred near Lake Pillsbury over the last few weeks, US Geological Survey records show.

The largest quake to take place in the Pillsbury area this month – a 4.8 magnitude – occurred April 18. US Geological Survey seismologist David Oppenheimer said that quake was the largest to hit Pillsbury in about 30 years.

Oppenheimer said this latest series of Pillsbury earthquakes – which have all been centered close to the same area – are occurring along an unnamed fault.
