| Zusammenfassung |
| This study is presented as a contribution to earthquake disaster mitigation studies
for selected cities in Turkey. The risk evaluations must be based on
earthquake hazard analysis and city information. To estimate the ground
motion level, data for earthquakes with a magnitude greater than 4.5 and
an epicenter location within a 100-km radius of each city were used for the
period from 1900 to 2006, as recorded at the Kandilli Observatory and
Earthquake Research Institute. Probabilistic seismic hazard analysis for each
city was carried out using Poisson probabilistic approaches. Ground motion
level was estimated as the probability of a given degree of acceleration with
a 10% exceedence rate during a 50-year time period for each city. The risk
level of each city was evaluated using the number of houses, the per-capita
income of city residents, population, and ground motion levels. The maximum
risk level obtained for the cities was taken as a reference value for
relative risk assessment, and other risk values were estimated relative to
the maximum risk level. When the selected cities were classified according to
their relative risk levels, the five most risky cities were found to be, in
descending order of risk, Istanbul, Izmir, Ankara, Bursa, and Kocaeli. |
