Lake point, AK/very weak vibration (MMI II)/rattling, shaking/2-5 seconds: I noticed this mainly because my house exploded and squeaked loudly for a few seconds. It was so important that I paused what I was doing to listen more carefully. I figured it was an earthquake because there was no wind and came here to check. Bingo!
