A scientific symposium was held in Nevada on the seismic situation in the world after the powerful tremors that occurred in Japan and Ecuador. American seismologists have gathered to assess the risks to the United States associated with the frightening calm in the Sierra Nevada Fault. The conclusions are disappointing, it does not bode well.
The director of the Seismological Laboratory of Nevada, Graham Kent, said that large earthquakes with a magnitude of up to 7 on the Richter scale occur in the Sierra Nevada fault every 30 years, but in the past 60 years not a single earthquake of this magnitude has been recorded.
In addition, tremors of magnitude 6 on the Richter scale occur in the Sierra Nevada every 10 years, but the last earthquake of this magnitude occurred in the Sierra Nevada 22 years ago.
The Sierra Nevada Fault runs along the California and Nevada borders. Starting at the southern end of Yosemite National Park and ending at Lake Tahoe. The fault is out of schedule, the absence of large earthquakes indicates the accumulation of energy in the fault, which may be splashed out by an explosion of seismic activity, expressed in earthquakes of very large - catastrophic magnitude.
