 Quake frequency normal, scientists say
Is it just me? This story is really odd, don't you think? Has CNN now started reading sites like ours or is it just a slow news day?

Hmmmmmm


By Jim Kavanagh, CNN
STORY HIGHLIGHTS

(CNN) -- Yes, it seems as if there have been a lot of strong earthquakes this year. And no, it's not a signal that the planet is coming apart at the seams, seismologists say. :hmm

The difference this year is not the frequency or strength of earthquakes, but their occurrence in or near population centers, the scientists say.

Major earthquakes in 2010 have caused death and destruction in Haiti, Chile, Mexico and Indonesia, and smaller ones have rattled nerves elsewhere.

"Natural processes become disasters only when they interact with people," said Seth Stein, a distinguished faculty member at Northwestern University in Evanston, Illinois.

"There are lots of earthquakes every year, but most of them don't do anybody any harm. And even big earthquakes don't necessarily do anybody any harm unless a lot of people live there," said Stein, the William Deering professor of geological sciences in Northwestern's Weinberg College of Arts and Sciences.

Earthquakes the size of the magnitude 7.0 temblor that struck Haiti on January 12 occur 15 to 20 times a year, but almost all occur in oceans or sparsely populated lands, he said. :dunno

"Earthquakes of magnitude 7.0 or greater have remained fairly constant throughout this century and, according to our records, have actually seemed to decrease in recent years," the U.S. Geological Survey, which measures and tracks earthquakes all around the world, says on its Web site. :hmm

The USGS attributes our heightened awareness of earthquakes to a number of factors, including larger populations in more places, better global communication and media reporting, and a wider network of seismic detection devices.

Kurt Frankel, an assistant professor at the Georgia Institute of Technology, told CNN after the magnitude 8.8 earthquake in Chile on February 27 that there's nothing unusual going on.

"I'm sticking by my story," he said Wednesday. "It may be possible there's been a little bit higher frequency of these slightly larger earthquakes this year, but it's such a random process that there's not a connection between them."

The geologic record suggests lulls and increases in seismic activity -- at specific faults, not globally, he said.

"I really think that part of it is just our heightened sense of awareness given what happened in Haiti, with all the death and destruction there, and then the fifth-largest earthquake on record just a month later in Chile," he said.

"I would be cautious in trying to say there's an uptick in earthquake activity or anything like that."

However, he's open to scientific persuasion, noting that instruments have been measuring earthquakes for only about 100 years, "less than the blink of an eye over the geologic time scale."

"This is science, right?" he said. "We need to keep testing that hypothesis and other hypotheses, and maybe I will be wrong and my mind will change if these things keep happening." :roflmao

Yes, L2, 3,093 Eq's in California and Nevada in 7 days is " Normal" according to the experts, I have been watching this page for years, and even posted on the first time the count went over 1,000 a few weeks ago, used to be about 300 to 600 was " Normal"
So, if I used to have one drink of Scotch, in the evening, and now I am having 5 or Ten , is that still Normal? Good post L2.

NOTE: hat tip to starrmtn001 There are two threads this evening about EQ's that have been deleted from the USGS list. The 6.0 in Vanuatu is one of them. There was also a 5.1 in SoCal that was deleted, then added as a 4.4 in the Mexican side of Baja.

Now there is another EQ that appears to have been downgraded twice! See the post on the Solomon Islands quake, found here: posting.php?mode=reply&f=46&t=1257#preview
