These pillar-like concrete benches were knocked over by the tsunami at Yalikent. Note the seaweed deposits and the grass that is turning brown from the salt water brought in by the tsunami. A leading tsunami depression wave that withdrew about 25 m was followed by a tsunami wave from the southeast with a measured runup of 1.6 meters. The septic system was flooded as the wave came in, causing a back-flushing of toilets and sinks. Several small boats were pulled out to sea, and two were lost. Wooden benches and other debris washed up on the beach. There was a permanent sea level rise relative to the small pier, indicating local subsidence of 15-20 cm. 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:
