Olancha, CA – Residents across portions of Inyo County and the Southern Sierra region experienced a light shake early Wednesday after a magnitude 3.3 earthquake struck west-southwest of Olancha. The quake was recorded at 5:18 a.m. PT, according to the U.S. Geological Survey (USGS).
According to USGS data, the earthquake occurred roughly 42 kilometers WSW of Olancha at a shallow depth of 4.3 kilometers, which often increases the likelihood that even smaller quakes are felt by people close to the epicenter. Early reports show no damage or injuries, and only a small number of “Did You Feel It?” responses had been filed as of Wednesday morning.
USGS officials noted the event is consistent with ongoing seismic activity along the Eastern Sierra and Owens Valley region, where small-to-moderate quakes are common due to complex fault interactions. The quake’s focal mechanism indicates movement consistent with local fault structures, though the exact fault involved was not immediately identified.
Residents in Inyo County, Fresno County, and remote areas along Highway 395 may have felt brief shaking. Light quakes of this magnitude typically do not cause damage but can serve as reminders of the region’s active seismic landscape.
Officials encourage residents to review emergency plans and ensure earthquake kits are stocked, especially as California continues to experience frequent low-level seismic activity. No aftershocks have been formally reported, but minor activity can occur in the hours or days following a quake.
