The Nevada Seismological Laboratory recorded an earthquake of M = 3.6 at 7:02 AM (PDT) Friday, June 23, near Minden-Gardnerville, Nevada. Another event of M = 3.3 at 6:55 AM preceded it. The preliminary location of the larger event is 38.75N, 119.61W, just north of Topaz Lake. The depth was computed to be approximately 9 km (6 mi). Today's earthquakes occurred in the aftershock zone of a M = 6.0 earthquake on September 12, 1994 (Double Spring Flat Earthquake). We have received several felt reports from Markleeville and the Minden-Gardnerville area on today's earthquake. Due to its relatively small size, we expect no damage.
The data reported here is preliminary. For more information, contact the Nevada Seismological Laboratory, (775) 784-4975.
