LA shook at 11:42:15 today according to the official record from the U.S. Geological Survey. But according to [a report of] Twitter activity today (by the tweetip site) it happened 43 seconds earlier at 11:41:32 (adjusted for time zone).

That Twitter routinely breaks news fastest is often discussed, notably in the wake of the May quake in China.
Today the AP’s wire posted news of the earthquake 9 minutes after it happened. 9 minutes is fast. Negative :43 is amazing.
(Yeah, yeah. I know. It’s explainable as an accounting error in twitter’s api or tweetip’s processing. But the point remains that twitter is always on the scene.)
