Correction: Not a quake but a sonic boom

What I thought was an earthquake turns out to actually have been a sonic boom caused by a meteor shower entering Earth's atmosphere.  Their velocity was great enough to create the earth-shattering sound that shook the whole Tahoe area.  I read a report in the Sacramento Bee today, and the description of what someone else felt on Sunday morning was what I also experienced.  I guess you had to be at a high altitude to feel it so strongly.  I've been up here before during meteor showers, which are truly spectacular in the black night sky above the Sierra, but none of them ever came close enough to cause a sonic boom!

Today is Shakespeare's birthday.  Happy birthday, Will!
