Pardon us while we burst your San Francisco bubble for a moment: The city of Christchurch, New Zealand was tossed about by 6.0, 5.5 and 4.4-magnitude earthquakes this weekend. The three quakes are all apparently aftershocks from the 6.3 magnitude quake in February. The latest tremblers caused several documented cases of liquefaction that essentially turned solid ground in to quicksand and swallowed entire Audi Sport Utility Vehicles. Now would be an OK time to review the USGS San Francisco Liquefaction Susceptibility Map. And maybe park your car somewhere else for awhile.
