Did the 8.8 Chile Quake Just Awaken The New Madrid Fault?

reply to post by TrueAmerican


Like I said earlier it could simply be that the media is focused on quakes and will report anything quake related. The following report is short but sweet. It states that the area has about 200 small quakes yearly. Still...

One just never knows.

Small earthquake shakes southeast Missouri

SIKESTON, Mo. -- The U.S. Geological Survey says a small earthquake shook southeast Missouri along the New Madrid (MAD'-rihd) Fault.

The agency says the magnitude 3.7 earthquake was detected at 1:37 p.m. Tuesday about 15 miles south-southeast of Sikeston. No damage was reported.

The temblor was felt as far away as Alton, Ill., and St. Peters, Mo., both about 150 miles north of the epicenter.

The earthquake occurred within the New Madrid Seismic Zone, which includes southeastern Missouri, northeastern Arkansas, southern Illinois and western Kentucky and Tennessee.

More than 200 small earthquakes occur within the seismic zone each year.

Well, that's still less than 1 a day. And now look:

MAP 1.6 2010/03/02 23:59:47 36.790 -89.340 8.1 4 km ( 3 mi) SSW of Anniston, MO
MAP 3.7 2010/03/02 19:37:35 36.788 -89.357 8.2 3 km ( 2 mi) ENE of East Prairie, MO

Two quakes in the same day, nearly right on top of each other. And again, very close to the epicenter of the big ones way back. Cause for alarm? Probably not yet- but I am definitely keeping an eye out for increased activity. So far at least it could be argued statistically that there has been. But time will tell.

I'm not saying it is and I'm not saying it's not.

But I was born in Cali there we had quakes practically everyday most too small to notice. I do know however that a large quake [Relatively speaking] is often followed by many after shocks.


It's still something to keep an eye on though IMO.

Picking up another quake on the New Madrid in GEE....not real big, probably in the 3.5 range...

Check the USGS...Another one just coming through

Yeah, I knew about that one before they reported it, as I saw it and tracked it down in GEE.

But I have another interesting situation. It could be that the stations on the New Madrid network picked up that Jakarta quake BEFORE the stations on the west coast, due to the distance possibly being shorter? I dunno yet, waiting on the USGS....as usual...
