3.6-magnitude earthquake strikes a mile from Costa Mesa – and then an aftershock

A 3.6-magnitude earthquake shook parts of Orange County on Thursday afternoon, June 6, the U.S. Geological Survey reported.

The quake, at around 4:52 p.m., was centered a mile southeast of Costa Mesa, 1.4 miles east northeast of Newport Beach, and 5.6 miles west southwest of Irvine, according to the USGS.

It occurred at a depth of roughly 7.5 miles.

The epicenter appeared to be a couple of blocks from Newport Harbor High School, according to the USGS map. The school is at the border of Newport Beach and Costa Mesa.

The earthquake could be felt across the county and elsewhere. In Costa Mesa, it threw a few hard jolts, along with some rocking, that made walls groan and windows rattle.

There were no immediate reports of damage or injuries.

A 3.4 aftershock located 1.6 miles southeast of Costa Mesa followed a few minutes later. That one was 1.7 miles east northeast of Newport Beach and 5.4 miles southwest of Irvine.

It was at roughly the same depth as the initial quake.

On Wednesday afternoon, a magnitude 2.6 earthquake struck Newport Beach. That epicenter also was just southeast of Costa Mesa.

Remember that the @USGS_Quakes has a website to report what you felt and that information will be used by the scientists. Did You Feel It? https://t.co/RX5Ll05X7k

Both the M3.6 and its aftershock are up on the site
