Lebec, Frazier Park, Pine Mountain Club, CA (Monday, April 16, 2018 at 9.40 a.m.)—Thanks to the caller who confirmed that according to the USGS “shake map” the location of the 3.8M quake at about 9:37 a.m. this morning is on the Wheeler Ridge Fault, which runs roughly perpendicular to and west of the San Andreas Fault.

Jeff Zimmerman from Neenach also writes that the Western Antelope Valley felt a jolt and heard rattled windows.

Lebec, Frazier Park, Pine Mountain Club, CA (Monday, April 16, 2018 at 9.40 a.m.)—The 3.8 magnitude quake was recorded at 9:36:48 a.m. by U.S. Geological Survey as 9.3 miles (15km) northwest of Grapevine (at the base of the foothills which is the start of the stretch of Interstate 5 often referred to as “the Grapevine”). The earthquake originated at a depth of about 7.7km according to USGS.  Just up the coast, 9 km north northeast of Alum Rock, CA, a 3.9 magnitude quake hit at 9:39:26 a.m., originating at a depth of 8.3 km. See the USGS map on this page. The blue dot is the Grapevine quake. [UPDATED: an anonymous caller just asked us to check the location of the quake, and said it was not on the San Andreas, but rather the Wheeler Ridge Fault. We are checking to confirm.]

In Lebec, resident John Delmos called The Mountain Enterprise (661.245.3794) to alert us to what he experienced: “It was a real short jolt. It felt like something rolling, like a vibration for a few seconds. Almost like a sonic boom, but sharper and you could feel it. It went bam! And then it was over, just like that.” Delmos did not mention any damage.

Lebec, Frazier Park, Pine Mountain Club, CA (Monday, April 16, 2018 at 9.40 a.m.)— A 3.8 magnitude earthquake originating 15 kilometers northwest of Grapevine was felt in the Mountain Communities at about 9:37 a.m.

Windows rattled in the Pine Mountain community and Frazier Park, but no damage has been reported yet. We will report more details as they are available.
