Skip to comments.Chileans worry over string of 300 quakes in north

"The situation is out of the ordinary. There's a mix of a string of tremors and their aftershocks that make things more complex to evaluate," Mario Pardo, deputy head of the Universidad de Chile seismology center, told the local newspaper La Tercera. "We can't rule out a larger quake."
The last recorded big quake to hit the northern area around Iquique was a devastating magnitude-8.3 in 1877. It unleashed a 24-meter-high (nearly 80-foot-high) tsunami, causing major damage along the Chile-Peru coast and fatalities as far away as Hawaii and Japan.
"The latest string of quakes is noteworthy because the last one happened in this seismic zone more than 130 years ago," said Paulina Gonzalez, an expert on seismic analysis at the Universidad de Santiago. "It's a zone where quakes should happen more often, and they haven't in a very long time."
Chile's worrisome seismic activity can be traced to just off the country's 4,000-kilometer (2,500-mile) Pacific coast, where the Nazca tectonic plate plunges beneath the South American plate, pushing the towering Andes cordillera to ever-higher altitudes. The 2010 quake released so much energy it shortened the Earth's day slightly by changing the planet's rotation.

I never thought much about quakes very much, even though I spent most of my life next to the New Madrid fault.
Since the big mag. 8 quake, early this year, here in the Philippines, I now know to keep abreast of quakes on a daily basis.
There are a number of quakes most every day, even though we do not feel them.
One can sign up for the USGS notifications that cover the world.
Drill Baby, Drill!
One of the commenters had a great line.
“It’s Bush’s FAULT”.
I hate ‘em. Glad that you came through that 8 pointer okay.
(Have never felt one that big, and hope I never do!)
Must be caused by all the fracking going on down there!
I think the quakes down there are being caused by the fracking going on up here...I say we blame Bush
