National Geographic - Nevada Mystery Quakes (2009) Information Nevada Mystery Quakes Local scientists try to ascertain the cause of a series of worsening quakes in Reno, Nevada. Is the city on the verge of a major disaster? At the same time, Blewitt's GPS (global positioning system) instruments on top of Slide Mountain showed that the mountain had moved six millimeters [a little less than three-tenths of in inch] horizontally outward from the quakes' epicenter and eight millimeters [a little more than three-tenths of an inch] upward. The movement was too large to have been caused solely by the earthquakes. "In that range of magnitude, the earthquakes are so small that even with 1,600 events, you wouldn't expect to see anything more than a millimeter [four-hundredths of an inch] of movement on the surface," Blewitt said. "It had to be something else that was creating the earthquakes and also causing the mountain to move." |
