A swarm of hundreds of earthquakes in Nevada has intensified recently, prompting experts to warn people to be ready in case larger ones hit.
Starting in July, some 750 earthquakes, mostly magnitude 2.0 to 3.0, have struck a corner of the Nevada desert near the Oregon border, according to several reports. Scientists believe groundwater is slowly percolating along the faults and building up pressure, making movement on the faults much easier, the Los Angeles Times reported.
