M 6.2 - 9 km SW of Aspen Springs, California

Maximum observed Modified Mercalli Intensity (MMI) VI

It was difficult to differentiate the effects of this earthquake from those caused by the shocks on May 25. It was felt over a similar area, however, and four people were injured. Minor damage was reported in several towns in the area. Landslides and falling rocks were common in Yosemite National Park. Old U.S. Highway 395, east of Mammoth Lakes, was closed because of severe cracks. Felt from Eureka and Las Vegas, Nevada, in the east to La Honda (San Mateo County) and Los Angeles on the coast. Many aftershocks were felt in the Mammoth Lakes area.
