Tsunami generated by the earthquake with a magnitude of 9.0 on March, 11, 2011 caused a high number of casualties and significant economic loss. Planning and reconstruction studies following the 2011 Tsunami in Japan are important examples of countermeasures to be taken against tsunamis In this study, observations from two field surveys conducted after five years following the tsunami event, focusing on structural and non-structural countermeasures in addition to disaster management and creation of disaster awareness studies are presented in details, and current measures in Turkey are also discussed.


GIS-based structural performance Assessment of Sakarya City after 1999 Kocaeli-Turkey earthquake from geotechnical and earthquake engineering point of view
Yılmaz, Zeynep; Çetin, Kemal Önder; Department of Civil Engineering (2004)
The August 17, 1999 Kocaeli-Turkey Earthquake (Mw=7.4) caused severe damage to the structures and lifelines in the Marmara region. Soil liquefaction was identified as one of the major causes of this damage. The aim of this study is to determine geotechnical and earthquake engineering factors that contribute to the structural damage observed in Sakarya city after 1999 Kocaeli Earthquake. For this purpose, the results of an extensive field investigation program compiled by General Directorate of Disaster Affa...

A strong earthquake with a magnitude of 7.5 occurred near the island of Paramushir (KurilIslands) on 25 March 2020. It caused a weak tsunami in Kamchatka and the Kuril Islands.Earthquake and tsunami data from three DART buoys are discussed and compared withnumerical simulations. It is shown that the calculated and measured tsunami characteristics onthe DART buoys is in very good agreement. There are also data on the recording of thisearthquake by a laser strain-meter installed in the Sea of Japan at Shults ...
Lessons Learned from the 2011 Great East Japan Tsunami: Performance of Tsunami Countermeasures, Coastal Buildings, and Tsunami Evacuation in Japan

In 2011, Japan was hit by a tsunami that was generated by the greatest earthquake in its history. The first tsunami warning was announced 3 min after the earthquake, as is normal, but failed to estimate the actual tsunami height. Most of the structural countermeasures were not designed for the huge tsunami that was generated by the magnitude M = 9.0 earthquake; as a result, many were destroyed and did not stop the tsunami. These structures included breakwaters, seawalls, water gates, and control forests. In...
The possibility of tsunami in the Sea of Okhotsk caused by deep-focus earthquakes
Zaytsev, A. I.; Pelinovsky, E. N.; Kurkin, A. A.; Kostenko, I. S.; Yalçıner, Ahmet Cevdet (2016-03-01)
The earthquake that occurred on May 24, 2013, in the basin of the Sea of Okhotsk with a magnitude of 8.3 was the strongest in this region. We have modeled a possible tsunami caused by such an earthquake. The simulations confirm that the wave heights were sufficiently small because the earthquake epicenter depth was 640 km. We analyze the oscillations of the DART buoys in the vicinity of the earthquake source and show that they were not associated with the tsunami waves. Analysis of the available pressure ga...
Recent changes in Turkish disasters policy: A strategical reorientation?
Balamir, M (2000-06-24)
Early morning at 03:15 on the 17th of August 1999, the devastating 45 second 7.4 Richter value Marmara earthquake took more than 18,000 lives in Western Turkey, the more developed industrial heartland of the country.1 The event left 300,000 dwelling units and more than 50,000 business premises in debris, forcing a population of nearly 600,000 to seek emergency shelter. A second traumatic incidence of similar magnitude took place a step further east on the same fault line, only three months later on the 12th...
