Hi gang!
Just talked to son in Indiana today, for first time since the earthquake (about a month ago?) He just noticed that some shingles around his chimney appear pushed up and thinks, perhaps, the quake might have caused movement of the chimney. He said the morning of the quake, he woke from a very sound sleep because it sounded like someone trying to break in, kind of like the thumping of a washing machine when the load isn't balanced. Wow! I've been through some very mild ones, but nothing like that. He has full basement, with wide fireplace in basement, so it is probably pretty sturdy. On end of house. Can a chimney like that move that much without cracking? he hasn't looked real close, but is very good about taking care of the house and does lots of his own work.
The only quakes I have experienced didn't make a sound, other than knick-knacks rattling on the shelf or dishes on the dinner table. Do quakes make a sound like that without structural sounds? Eek!
