30 September 2008, 757pm: The 3.0 magnitude bump recently felt, by my ass, on the hardwood floor while halfheartedly watching the closing credits of a three-year-old episode of “Curb Your Enthusiasm” serves as a friendly, if not altogether unsettling, reminder: It is time for my ass to get my ass off of the floor and start making his way over to the Temple Bar for the venue’s closing party tonight. End of an era and all that. Hop to it, ass.

A strong earthquake with a preliminary magnitude of 5.4 shook large parts of Southern California, shaking a wide swath from Ventura County to San Diego.

The quake shook downtown L.A. buildings and was felt as far east as Palm Springs.

It was centered near Chino Hills, about 30 miles east of Los Angeles, the U.S. Geological Survey said.

There were no reports of major damage or injuries. But the Los Angeles Police Department reported minor structural damage at Los Angeles County-USC Medical Center.

The magnitude of the quake was originally set at 5.8. But Caltech officials downgraded it to 5.4 and said they doubted the temblor caused major structural damage. [LAT]

Were you up? Did you feel it? Details here, here and here . . .

It just shook me - bigtime! Still a bit woozy. Leave your take or any other quake-related chatter in the comments.

UPDATE: Quake has now been upgraded from a 4.5, as initially reported, to a 4.6. Definitely felt like a 4.6 to me; good to see I’m not in the wrong.
