whole lotta shakin'

So I experienced my first earthquake the other night. Apparently, I'm right over the Western Quebec Seismic zone:

Pretty intense. The quake, which was accompanied by an eerie rumbling sound, went on for about 12-15 seconds, shaking the whole house and everything in it. No damage, but it was an odd sensation to feel the earth itself moving beneath you.
