Earthquakes Increasing In California Region, Scientists Say
April 13, 2010
While the area has been fairly dormant in recent years, the sudden increase in activity has alarmed scientists, who are hard pressed to explain the change.
Since the beginning of 2010 there have been 70 quakes over a 4.0 magnitude. That is 40 more than there were in the whole of 2009, and it is only April.
The sudden drastic boost in number is due to an increase in seismic waves in the region, though experts are not sure what has caused it.
So far, they believe it might just be the activity picking up after a time of lying dormant, entering a new round of quakes that will become increasingly common.
Scientists say that smaller ones will happen more frequently, but larger earthquakes are sure to be seen more regularly as well.
“We would like to be able to explain it,” Caltech seismologist Kate Hutton said. “But there’s no real correlation with any cause.”
