think i can remember at least 2 reported for this area. know at least one was in the mid 80's. had a cat that was acting strange then. i felt that one, just slightly it was about coffee break time.

this is strange, as i just emailed someone who posts at synergy board and sometimes glp. TIEMPE. i had questioned if she saw anything for new madrid area as i live here, and both my pups acting sorta strange. thanks for the update.

After the freak IL quake on the 28th, I thought that this was strange. I have studied the New Madrid extensivly and many geologist belive that it is over-due. The quakes in Illinois and Ohio are not "technically" on the New Madrid Fault system, but data on the fault is very limited. With the exception of a few magnitude 5's on the system in the past 200 years, there is very little data to map the various appendages of the fault. When I first discovered the Cleveland quake, it made me think of a prediction that I recently heard about the great lakes emtying into the gulf due to a massive quake.

starky's right.
I grew up outside Cleveland and sometime during second grade (85-86 or so) we had a minor, but feelable earthquake.

This is an aticle posted on another board from 1994. I had no idea that there were known faults in that area.

Researchers warn of earthquake
-- For immediate release

Researchers warn Southern Ontario may face earthquakes

WATERLOO, Ont. -- If a controversial theory put forth by a team of researchers studying seismic activity in Lake Ontario proves correct, Southern Ontario is more earthquake- prone than was previously believed.

..and I remember the two mentioned above, I think one was in the mid 80's and the other was in the early 90's. I seem to remember reports at those times saying the quakes were due to action along the New Madrid fault that lies either right near or under the Mississippi.

There is a very good web site available that allows you to see if there are any KNOWN faults in your area. Click on the "Map-Based" link for fastest access.

It's not perfect - it only shows KNOWN faults, and you will notice that there are none shown in the Cleveland area.
