1971 Sylmar quake and some 1994 Northridge quake pics






The latter started about 630A 2/9/1971; the former about 430A on 1/17/1994. Both seemed to have upward thrust motions...severely disturbing brick buildings and buildings on liquified soils. Both were about the same size. Included is a historical showing of past earthquakes...these can be seen on lower belts below the fault surface...maybe datings can go back a couple of thousand years.

That last pic was a Bell Telephone Co. truck. Two employees were in it.
