I wonder if New Madrid is getting antsy, again.

Yeah, I guess a long time ago that was a big one. Hard telling what it might do
these days if it let loose with a major jolt.

There's quite a bit
of seismic activity downstate that originates with pressures bearing on
the New Madrid fault.

I didn't feel anything here. But that's probably why I'm still single.

But thanks for the head's up. I'll check the seismograph at the
Planetarium when I'm down there this weekend.
