There was just a 3.8 to 4.2 earthquake in north central Indiana, about 180 miles from me. That would put it right above Solitaire's territory and near Kokomo.

I didn't feel the wave here.

Quakes are rare in this area, as the strata beneath us is mostly thick Silurian and Devonian limestone, still very flat after hundreds of millions of years. But occasionally, in limestone - which is subject to Karst effects that create subterranian caverns because of water seepage - collapses down there do occur and create small quakes. But not usually so high on the Richter scale. This one was probably associated with a fault below the limestone sediments.

I lived on fault lines for 30 years and I don't miss the quakes we had so frequently in Long Beach. My house was a little over a mile from the Newport-Inglewood fault which last shifted in 1933 and killed around 100 people there.
