Geocache Description:


Desert cache along a decent dirt road (bumpy) that any vehicle with a little extra clearence could make. With that said, cars would not be advised and watch out as the road conditions can change anytime. At the cache location there is a pull out to park off of the main dirt road. Watch your step as the rocks can be loose and the the regular desert critters are out there. 

 This cache is placed just over 1.5 miles from the epicenter of the 6.5 earthquake that struck on May 15th. Its the biggest Nevada quake in over 60 years. There have been quakes in the 7 magnitude range in a few areas of the Nevada. One not to far from this area of the state. If you look to the SE you'll be looking towards the Epicenter. The aftershocks have been happening along the fault directly under your feet all the way to the hills to your NW. Looks like the ruptured fault is running around 34kms long, i will update when the official study is over. With that in mind, if you see USGS or government trucks out here please let them complete their field work and do not poke around any equipment you see out this way. They have deployed seismographs and some other motion sensors in the area. 

Below is the current words from the USGS offical earthquake page https://earthquake.usgs.gov/earthquakes/eventpage/nn00725272/executive

The May 15, 2020 M 6.5 earthquake 56 km west f Tonopah, Nevada, occurred as the result of strike slip faulting in the shallow crust of the North America plate. Preliminary focal mechanism solutions for the event, which describe the style of faulting in an earthquake, indicate slip likely occurred on a steeply dipping fault striking either east-west (left-lateral) or north-south (right-lateral). This earthquake occurred within the Walker Lane, an active zone of seismicity roughly aligned with the California-Nevada border. Tectonically, the Walker Lane accommodates up to 25% of the North America:Pacific Plate motion, with the remainder mostly accommodated on the San Andreas fault system.

About two dozen M5+ earthquakes have occurred within 100 km of this event over the past 50 years, mostly to the west and south. Two M6+ events have occurred over the same region in the past century – a M 6.5 earthquake 40 km to the northwest in January 1934, and a M 6.8 event 50 km to the north in December 1932. Both of these earthquakes caused severe local shaking (MMI VIII); the 1932 earthquake is documented to have caused damage in the sparsely populated surrounding region. As of 12:00 UTC, 6 M4+ aftershocks have occurred since the M 6.5 earthquake, extending over a region about 30 km to the west of the mainshock.
