Dear Frank,

I didn't live in this house, but my sister did.  During the Northridge
earthquake, her house lifted off the foundation and moved several feet
sideways and reutrned to earth.  Her house is located in the Silverlake of
Los Angeles (for the non-locals, it is  between Hollywood and Downtown) and
the house was built in the late teens or early twentys, two-story and
featured ship-lap siding instead of the usual stucco.  House had a partial
basement and was located near the top of the hill.  Other houses in the
area, I believe, suffered cracked brick fireplaces.  The house was declared
a total and now she and family
live in an engineered house.
