The epicenter was located 2.7 km (1.7 miles) N of Fletcher (population 0), 29 km (18 miles) WSW of Hawthorne (population 3 200), 92.2 km (57.3 miles) SE of Gardnerville Ranchos (population 11 312), 112.3 km (69.8 miles) ESE of South Lake Tahoe (population 21 403), and 114.8 km (71.4 miles) SE of Carson City (population 55 274), Nevada.
There are about 31 222 people living within 100 km (62 miles).
EMSC estimates there are about 5.5 million people living in the felt area.
USGS issued a green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.
Overall, the population in this region resides in structures that are resistant to earthquake shaking, though some vulnerable structures exist.
Recent earthquakes in this area have caused secondary hazards such as landslides and liquefaction that might have contributed to losses.
The Mineral County Sheriff’s Department in Hawthorne, Nevada, near the epicenter, has not had any reports of injury or damage, CBS reported. The office says the quakes apparently set off burglar alarms at two businesses, and caused a rock slide that did not block a nearby highway.
A boulder rolled onto a roadway in Hawthorne, KTVN reported.
This region was hit by a string of minor earthquakes in July 2016 and March, April and May 2011.
