Following a 5.4 earthquake that dealt most of its damage to people's Facebook status updates ("Jim is: EARTHQUAKE!"), it was only natural to wonder how the tremor might have affected the city's old, its infirm, and its Big Brother 10 residents. Fortunately, the Hollywood Reporter can help us out on at least one of those fronts: its video update reveals that the Big Brother houseguests bypassed the "Is that a truck? Oh, wait..." stage experienced by most Los Angelenos, instead rushing out into the backyard to doff their clothes and trade "Omigawds." Video after the jump.

Even the brave souls at E!'s Sunset Tan were not immune to the quake, though they faced it with their clothes already off:

"Sunset Tan" sales rep and cast member Holly Huddleston was stuck in a tanning booth when things started to vibrate during an FHM photo shoot promoting the E! series.

"I was in nothing but a bra and panties and wearing these high heels when everything started shaking," Huddleston said. "I kind of stopped and looked around to see if it was just me, if I was the one shaking or if I was just positioned funny.

Satisfied that the shaking was due to natural causes and not a few too many Stoli/Red Bulls, Huddleston went back to work, bravely illustrating the (paraphrased) axiom that "a woman can do any earthquake a man can, she just has to do it backwards, in high heels, while a photographer grouses, 'Can someone keep those nipples iced up?'"
