My First Quake
It happened this morning at approximately 1am and I slept right through the damn thing! Man am I pissed. I've been looking forward to my first earthquake for months now. Kind of like when I saw my first rattlesnake out here, only I did not miss that! LOL!
Anyway, 4.5 is not bad on the scale and the event helped me find this site: Recent Earthquakes
It comes complete with a map showing all the activity in the past 24 hours with little colored boxes of varying sizes depending on magnitude. Did you see that? No commas in that last sentence. In addition to the multi-colored boxes you can click on a box for a report such as that given regarding last nights Rumble In LA:
