Beneath the surface of California, as in a boiling pot with a lid slammed, increases pressure, which may at any moment break out the monstrous earthquake. This is consistent with the new study the Scripps Institution of Oceanography.
Geologists say that Southern California has long not been a giant earthquake which could cause widespread damage.
It all depends on the Lake Salton Sea, located east of San Diego. The Salton Sea is located directly on the San Andreas Fault and covers an area of over 350 square meters. miles (906.5 km 2, approx. mixednews).

Major earthquakes affected the lake bed about every 180 years. But when the authorities began to partition off the Colorado River to reduce flooding downstream (including the Salton Sea), a moderate earthquake in the Salton stopped.
Is encouraging, is not it? Not necessarily. Seismologists believe that the construction of the dam stopped the earthquake of moderate strength, which resets the tension in the Salton.
Now, they fear that the pressure builds up, and the area could be late to the mega-quake, numbering in strength from 7.5 points to at least a hundred years.
These sobering news come just at a time when the published results of a new poll, according to which the people of California have a fear of earthquakes and other natural disasters.
Most threatening natural disasters, according to Californians
Forest fires 23%
Tsunami / tidal waves 9%
Flooding / mudflows 5%
Other / no opinion 6%
The research results were published in the scientific journal «Nature Geoscience».
