Did you feel it?

If so - you can post the info here. The USGS wants to know.

I felt it but wasn't sure what I felt, lol. I checked it out today on the USGS site. No one else had logged that they felt it here in Charlotte. I felt it at about 6:38 am. Surely I am not the only person who felt it? My chair gently shook for maybe 3 - 4 seconds.

Small Earthquake Shakes Some In South Carolina | AHN (http://www.allheadlinenews.com/articles/7016248786?Small%20Earthquake%20Shakes%20Some%20In %20South%20Carolina - broken link)



SUMMERVILLE, S.C. (AP) - The U.S. Geological Survey says a small 3.2 magnitude earthquake has been reported in South Carolina near the coast.

Moderate tremors were felt for three to five seconds at about 6:30 a.m. Saturday. The tremors were followed by a series of weaker vibrations.

No damage or injuries were immediately reported. Some residents experiencing the earthquake reported hearing a loud explosion.

The earthquake was centered about two miles northeast of Summerville, which is about 15 miles north-northwest of Charleston.

I did not realize that loud booms accompany earthquakes til I read the articles about this earthquake. I have only felt small tremors, both here in NC and also when in California. It makes sense that there would be noises, of course, but I just never heard anyone say that! I went on several websites in SC and people were saying they heard 2 loud booms that sounded like explosions.

I think animals sense the disturbance before people - it seems from reports that they do. I wonder what it is they feel? (or maybe it is a sound at a pitch we can't hear??)

Earthquakes are series of waves that move through the ground. Imagine a pebble dropped in a pond. You see the waves moving towards you on the shore, but you can't feel them until they get to you. Humans can't hear or feel the ground waves of an earthquake anywhere as soon or well as the critters - same as a dog will bark about a car coming before a human knows its there, or howl at sirens that merely annoy us, hide under the couch before we even know the storm has arrived...etc.

If you ever have the chance to go to the Exploratorium in San Francisco, they have an "Earthquake Experience", where you stand on a "floor" and feel different levels of seismic activity, and the sounds that go with it. It can be REALLY loud! It is the earth getting broken and torn, after all.

Typically, and definitely in this case, it was a small earthquake and we're far enough away from the epicenter that we got the "small" ripples, like you would see at the edges of the pond from that dropped pebble, so we don't get the noticeable level of noise that you would hear closer to the epicenter or if it were a "major" earthquake.

Making a note . . . will definitely go to the Exploratorium next trip to San Francisco. Haven't been in a decade! Hope it won't be long b/f I head out that way.

Well, shoot. Surely I was not the only person in CLT to be up and at home. It was very gentle and I think most folks would not have even noticed it. I have been tracking earthquake activity since I got online in late 93, wh/ was not long before the Northridge earthquake hit in the Los Angeles area. So I notice such things.

Probably since it was at the coast and only a 3.2 magnitude, it did not reach all the way up here to University City. But, I was driving DS to church (he does set up and has to be there at 6.30)...so, actually, I was probably on my way back home at that time, but, one would think that there would be stop lights swaying or something.

On the USGS site, folks all the way into VA and W VA felt it.

I had a bottle of water on my desk and after the slight shaking stopped, I thought - what the heck? And then I realized it could have been an earthquake, so I glanced at my bottle of water - and sure enuff - the water was still settling down. So it was gentle, but yes, it was visible. I think it would take a whole lot to make stop lights swing, lol. This was like someone would stand behind a chair and just gently "jiggle" it.
