Are We Having an Unusual Number of Earthquakes?

Nope, probably just an average year:

Folks who work at the United States Geological Survey Earthquake Center in Golden, Colo., don’t just track temblors, they also answer the public’s questions via phone and email. The number one question they’ve been getting lately: “Is this the end of the world?” according to Heidi Koontz, the center’s Public Affairs Specialist.

News of four major quakes in as many months, in Haiti, Chile, Mexico and Indonesia, has prompted a tinge of panic in some who would otherwise consider these events pure coincidence.

“I received a call from a psychiatrist who is getting an influx of patients who are really concerned about the end of days,” says Koontz, “and he wanted us to pinpoint science and provide him with links to science that would help allay the fears of some of his patients. He needed some hard facts and he said that that actually helped.”

Koontz explained to the doctor what seismologist Harley Benz explained to Fox News. That seismically speaking, this is all pretty normal.

“You can expect earthquakes in locations where we are known to have earthquakes,” explains Benz. “And in this case, in Sumatra, it's one of the most seismically active areas in the world. Likewise Chile is one of the most seismically active areas in the world.”

According to the USGS Earthquake Center website, earthquakes can also occur in clusters, which may explain why this year has been front loaded with so much activity. Statistically, the globe is on track, so far this year, to be relatively average in terms of the number of larger quakes that hit annually. An average year will produce 17 quakes with a magnitude 7.0 or greater.

Things have been pretty quiet in Southern California for the last 15 years or so. Unfortunately, we're due for some shaking.
