Last night we had an earthquake somewhere beyond Beyond Ester. In the past, I have experienced earthquakes as the ground or building swaying, sometimes a shudder that seems to emanate from underneath. But last night, the symptom was a sudden craaaccckk from the logs in the house. Earlier, it had been very windy, so when I heard the logs cracking and creaking, I took the dogs out to determine if we needed to evacuate the house, gather kitties, and head to a storm shelter. After eight years in Iowa, one of my first reactions to strange surging sounds is to find a solid shelter. But when the dogs and I opened the door to the outside, all was silent. No fiercely clanging windchimes, no madly swaying birch trees. We came back into the house, and I noticed that my alarm clock had tipped over. Some of the dishes had slid in the cabinets. Kali, the complacent and usually oblivious elder cat, was sitting up, her eyes wide. Ahhhhh... an earthquake, I thought. This morning, I mentioned my experience to my co-worker, who directed me to UAF's Geophysical Institute earthquakes info page. What a wealth of information! It looks like the earthquake we experienced was about 150 miles south of Beyond Ester. I'm curious about how the shock waves travel... do they emanate through rock like water waves? Or more like sound waves traveling through the air? Regardless, it was an interesting experience, but not one that I need to replay.

Thanks, GI!
