Next Big Midwest Quake Poll

[mrslinarcos]

Would be interested in what all of you think will occur next in the Midwest? A 7 up with Wabash Valley Fault or an 8 from the New Madrid Fault. Thank you for your kind input.

The New Madrid would be my guess for a big quake and if it was 7.0 or larger it would be a disaster for a large area of the Midwest.

Wabash, only because I was always told to expect the unexpected, they've been talking about New Madrid foever it seems, I never hear much about the other.

And the reason no one heard much about the Wabash Valley Basin, was because it's waking up. I figure it's been in wake up mode since '87. I've been hearing from some friends of mine telling me that the quakes we had here last month was due to the wettest winter season. I don't know if that could be a huge contributor to the quakes.

Wow, this is 50/50, so I guess the odds of being correct are better than the 2008 hurricane poll.




I thought the Indiana/Illinois activity may just be an extension of the New Madrid zone anyway.


How about adding that feature in Eastern Kansas, and whatever produced the earthquake near Charleston, SC about 200 years ago.

As to the split on the poll, I'm not doubting the feelings of those who participated. I will in the next poll put in those areas as you requested. I think the reason why the poll was pretty much split, is
because it's been so long since the area has been hit with an above 7.0 on the scale. It would be rather odd if one set off the other, even though most seismologists think things like that can't happen. The plates below say otherwise.
