Risk areas are located mainly around San Francisco and Los Angeles. This has been announced by a group of scientists who have gathered to assess the risk of an earthquake that exists around the San Andres fault in California.
This failure limits the peaceful plaque to the American plaque and extends from northern San Francisco to the border with Mexico.
It is estimated that the earthquake can reach a magnitude of 7.5. San Francisco and Los Angeles are heavily populated regions (5.5 million inhabitants and 12 million inhabitants respectively) and a geological accident of these characteristics can cause an incalculable disaster, both by the loss of human lives and by the loss of goods.
As an example, the earthquake that destroyed San Francisco in 1906 was of magnitude 8.3.
