Izmit Bay Tsunami Survey

Aug 22 - 26, 1999

A large Earthquake occured in Western Turkey on the Northern Anatolian Fault. Along with this earthquake, it was suspected that a tsunami also occurred along the coast of Izmit Bay, in the Sea of Marmara. A Survey team from USC went to Turkey on Saturday August 21, 1999 to investigate reports of a tsunami.

The team consisted of Dr. Ahmet Yalciner a visiting USC professor who is from Turkey, Dr. Costas Synolakis, and Jose Borrero. Joining the group on the second day were Martin Eskijian and John Freckman of the California State Lands Commision, whose interests were the effect of the earthquake and tsunami on marine oil transfer facilities..

The group was able to determine that the reports of the tsunami were true with maximum runup of 2.5 m along the northern coast of the bay and 1 to 2 m on the southern coast.
