How does the facility of as we speak’s earthquake evaluate to California’s greatest tremors?printed at 22:12 Greenwich Imply Time 5 December

Greater than 80% of San Francisco was destroyed following a devastating earthquake in 1906
Immediately’s earthquake off the coast of California reached a magnitude of seven.0.
This area of America is the place among the Earth’s tectonic plates meet, usually leading to friction that passes as much as floor degree.
However a 7.0 magnitude quake is not typical within the area, or for that matter, anyplace that will get frequent earthquakes. Between about 10 to fifteen earthquakes of this energy are recorded globally every year.
So how does as we speak’s tremor evaluate to a few of California’s largest earthquakes?
There have been 12 different earthquakes measuring 7.0 or higher, in line with data, external that has been recorded since 1800.
In 1994, a 6.7 quake hit Northridge, a neighbourhood within the densely populated San Fernando Valley area of Los Angeles. About 57 individuals died (this quantity is probably going increased due to individuals who had coronary heart assaults), and 1000’s have been damage. It precipitated about $20 billion of injury.
In 1906, greater than 80% of San Francisco was destroyed following a 7.9 magnitude quake, which led to widespread fires and the deaths of three,000 individuals.
There have been no fatalities or main injury recorded so removed from as we speak’s occasion.
