The waves of energy from an earthquake create a "whiplash" effect in buildings, with damage being much more concentrated where the "whip" energy of the earthquake, reverses itself - "cracking".

That was the sort of thing I was thinking, maybe involving some kind of harmonics in the building and the frequency of the earthquake waves.

I like to tell visitors to DC that that's the high-water mark from the flood.

Monterey Bay: When I was a kid I worked at the Boardwalk on the beach. Tourists from all over the world would show up and often would point across the bay at Big Sur which sort of rises up abruptly from the end of the Monterey peninsula and ask, "what's that?"

I'd always tell them "Hawaii". Many believed me.
