The University of Nevada Seismological Laboratory recorded an earthquake of M = 4.0 at 10:58 AM (PDT) Friday, October 8, near Scotty's Junction, Nevada. The preliminary location of the event is 37.36N, 117.11W, approximately 12 km (7 mi) NNW of Scotty's Junction. The depth was computed to be approximately 7 km (4 mi), but depth is not well determined due to lack of near recording stations. Several aftershocks have been recorded, with one measuring 3.6 in magnitude approximately one-half hour later. This location had a M = 5.7 earthquake on August 1 of this year, and thousands of aftershocks had been recorded at the Seismological Laboratory before yesterday's event.

The data reported here is preliminary. For more information, contact the Seismological Laboratory, (775) 784-4975. The free pamphlet "Earthquakes in Nevada and How to Survive Them," is available on request.
