One of my friend has a small apartment building in Napa. 2 Hot water heaters(with earthquake straps) broke away from the supply lines and flooded the whole building. It was like that all over the area, The street buckling was the most incredible stuff. Some up to 3 feet in the air where the ground heaved together underneath the road ways and side walks. Saw some lane striping that had almost a foot shift where the fault crack moved side to side. Luckily most of the homes are on slabs so they ride out the quakes real well.
