    I didn't feel it here in Jersey, but when I got back to my bldgs everyone was standing outside! Some knuckle-head called 911 and told them that windows had cracked, do the fire dept came with police, evacuated everyone and found the cracks to be spider webs on the glass lol.

    This map might put things in perspective:

    Some east coast earthquakes from 1698-1997 (from http://www.geology.enr.state.nc.us)

    The green dots, and certainly the yellow dots, can be felt noticeably by people indoors if you are near the epicenter.

    Yup, got the sheep skin and everything, but I then went into the AF instead of the field and it's been just a hobby / latent passion.

    Cool! A had a professor years ago who was a geologist for the Army. Apparently, he contributed quite a bit of knowledge to help troops in the Korean War (assessing the quality of terrain).

    I grew up in SoCal and I've been throug my fair share of quakes. Just remember one thing: In California building code requires steps be taken to make sure the primary structure, in theory, can survive up-to a 5.0 quake. Such is NOT the case in Virginia. :(

    The 1994 Northridge quake was a 6.7 (which is almost an entire order of magnatude larger than this quake in VA :eek6:) and did some wicked damage to a metropolitan area that is built to deal with earthquakes. [ame=http://en.wikipedia.org/wiki/1994_Northridge_earthquake]1994 Northridge earthquake - Wikipedia, the free encyclopedia[/ame]

    It sounds like the damage is minimal and I haven't heard any reports of deaths (I hope there haven't been any) so I am thankful for that. :cool:

    This is fun. Here's the seismogram from Virginia Tech in Blacksburg, VA (z-axis). Each line records 10 minutes across, then it drops down a line. Small tremor around 2am, then it goes nuts a little before 2pm.

    Yep, felt it here in Columbus. Everyone stood up from their cubes wondering WFT was making their desks shake. Caused the water in my glass to sway a bit.

    Here is an intensity map thanks to all of you who reported what you felt to the USGS. Before modern seismometers were widely available, this is how the epicenter was located. The star is the epicenter located by seismometers.
