I live in Iowa. I had just gotten up and was blearily checking HN and email - and I was swaying in my chair. I thought "Boy am I groggy; I can hardly sit upright" and some passing thoughts of incipient Parkinsons flitted through my head.

Then I read this an hour later. I guess it was an earthquake I was experiencing! A mixed blessing to be sure, but nice to know I'm not as decrepit as I thought.

Same article on AP without the signin crap: http://bigstory.ap.org/article/34f0e22aa7f94ca187d02886167f1...

Thank you. My back-button reflex to those ads and teaser text pages has never allowed me to subscribe.

Thank you.

This morning at 7:05 am CST DFW. Felt the tremor and the house let out a small creak. My wife thought someone was shaking the bed but noticed no one was there. She starts to think it was some kind of supernatural event...LOL. I told her it was the Earthquake Ghost....

It's hard to imagine what people must of thought of such an event 100's of years ago before modern day science.

I'm on a high floor of a highrise in Uptown, Dallas. The building was shaking and swaying hard enough to wake me from sleep.

All of my friends from Arkansas said they'd never move to California, like I did, because of earthquakes. Now they have tornados AND earthquakes. Looks like I made a good choice!

It will be interesting to hear to what extent fracking is to blame for this.

There are a bunch of rigs just south of the epicenter operating at a well depth of around 5-10 km deep which is how deep this quake/aftershocks were

Likely entirely to blame. If you've not been following what's happening in states which allow injection disposal of waste-water fracking, start here:

We're just about 20 miles north east of Dallas, but didn't notice it at all. Interesting that others have. I'll be curious to hear more reports about it and talk to some neighbors.
