Izmit (Kocaeli) Turkey Earthquake, August 17 1999. Set 1, Coastal Effects
Guzelyali is a small fishing harbor on the south shore of Izmit Bay. The harbor is located behind a breakwater. According to reports, a leading depression wave was followed by a tsunami overtopping the seawall in the back of the harbor, causing small boats to lose their mooring lines. When the sea wall was measured, a height of 1.25 m was obtained for the tsunami. The entire harbor was covered with a 2.5 cm to 15 cm (1-6 inch) thick layer of oil that may have come from the large refinery fire across Izmit Bay.A tsunami flooded this collapsed building east of Guzelyali. Subsidence along the shoreline made the piers and moorings unsafe. Tsunami data collectors had to approach the shore by boat to take measurements of tsunami runup. Partially submerged trees are visible in the left background.
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.
