Summary:

The moment magnitude (MW) 6.5 Monte Cristo Range earthquake occurred 56 km west of Tonopah, Nevada on May 15th, 2020, at about 4AM PDT. The Monte Cristo Range, where the earthquake epicenter was situated, is located in western Nevada and lies along the east of Highway US 95, an important highway connecting northern and southern Nevada. The earthquake epicenter was located in the Walker Lane, a seismically active zone along the California-Nevada border. The reported faulting mechanism was strike-slip in shallow crust. This report summarizes the preliminary findings by the NSF-sponsored Geotechnical Extreme Events Reconnaissance (GEER) team which visited the Monte Cristo Range area. The GEER team was mobilized to the epicentral region 3 weeks after the main event, and the area of interest was decided based on findings by other advance teams from United States Geological Survey (USGS), Nevada Bureau of Mines and Geology and the University of Nevada – Reno (NBMG/UNR) and California Geological Survey (CGS) which had pointed out some interesting ground failure patterns in the Columbus Marsh area west of US 95.
