There was a small quake when I was at 29 Stumps, we were directing live fire during a CAX (Combined Arms eXercise) and all these rocks starting falling down on us. At first I thought one of the PFCs or LCPLs was goofing around but then the ground got all shaky. The strange part is how things get completely still right after and if the exercise wasn't going on, I bet it would have been eerily quiet right after it stopped also. Its like everything had to check to make sure its back to normal before life can continue on, spooky.
Two years ago, the dogs start going nuts right before going to bed about a half hour after midnight. Then there is a loud almost indescribably noise with a simultaneous jerk, then all the alarms and sirens start going off. Find out the next morning that the cabin is a thousand yards from the epicenter of an earthquake. Others farther away said there was some shaking, but all I felt was a quick shuddering jerk.
My father slept through the big one they had in Tennessee 20 or 30 years ago. He woke up in the morning and called down to the desk and said somebody must have broken into his room during the night and vandalized it (it was before he had his coffee and he wasn't thinking). The clerk told him there had been an earthquake and many of the guests had reported room damage. Lamps were on the floor, pedestal TV turned over, and so no, he said it looked like some Frat Boys trashed his room.
