3 Scientists feel major earthquake long overdue

Seismologists have been busy keeping track of a swarm of earthquakes south of the San Andreas Fault. Experts are of the opinion that the Fault is long overdue for a mega earthquake of 7 or more. Increased seismic activity in the vicinity of a fault is always cause for grave concern as such activity could trigger a bigger one.’

The southernmost stretch on the San Andreas Fault hasn’t ruptured since the year 1680. But according to scientists a large earthquake usually happens in the area on an average of every 150 to 200 years. This means the San Andreas Fault earthquake is long overdue.
