Over the last day, the US Geological Survey (USGS) has detected 16 moderate tremors, all stronger than 2.5 in magnitude, in the vicinity of Tonopah Test Range in Nevada, better known as ‘Area 52.’ Both Area 52 and its more famous neighbor, Area 51, sit on a massive complex just north of Las Vegas called the Nevada Test and Training Range (NTTR).
