Earthquake damage along the south coast of Izmit Bay. Note the flattened building on the shore and the boat between the trees. All the windows appear to be missing on the first floor of the other buildings. Debris from the tsunami has been deposited in the trees. In Halidere, all of the boats normally on the beaches floated 30-50 meters up the streets. The measured runup here was between one and two meters. A mooring buoy was deposited in one resident's back yard. Seaweed traces were found 50 meters up a street. The residents reported that the sea level had risen two meters or more and that a beach in front of the seawall had disappeared. A road ended abruptly in the bay. Everything had subsided about two meters. Image Credit: Jose C. Borrero. University of Southern California August 17, 1999 Izmit (Kocaeli) Turkey earthquake On August 17, 1999, at 3:02 am local time (00:02 GMT) a magnitude (Mw) 7.4 earthquake occurred on the northern Anatolian fault. The epicenter was located very close to the south shore of the Bay of Izmit, an eastward extension of the Marmara Sea. The location of this earthquake and its proximity to a populous region on the Bay of Izmit contributed greatly to its damaging effects. The total estimated loss for port facilities in the region was around $200 million (US). Subsidence and slumping caused much of the coastal damage, but a tsunami was generated that also caused coastal damage and deaths. Event Data:
