摘要

On 17 August 1999 at 3:02 a.m. local time, the Izmit earthquake occurred on the North Anatolian Fault Zone (NAFZ) in the northwest Turkey. The surface rupture caused by the 1999 earthquake (Mw: 7.4) comprised four segments: the Goelcuek, Izmit-Sapanca and Arifiye-Akyazi segments in the west (about 90 km long) and the Goelyaka segment in the east (about 30km long). The death toll in city centres was 15,851 and reported injuries 43,953 in greater urban areas the death toll was approximately 18,000 in total and reported injuries approximately 48,000. In this study, SPOT HRV (XI and Pan) images obtained before and after the earthquake were used to estimate the area of collapse buildings in Yalova city. The pre-earthquake and post-earthquake images were geometrically corrected and classified separately. Image differences between on 06 June 1993 and 9 September 1999 SPOT HRV Pan images were used to determine changes due to earthquake damage. In addition to this, urban spatial growth ofYalova city analyzed using SPOT HRV images between 1993 and 1999. Results, which were obtained by processing satellite sensor images, compared with government office and ground data.
