Shakemaps of the Van, Turkey 2011 earthquake

The production of estimated maps of shaking after an earthquake, such as ShakeMap (Wald et al. 1999), offers an important seismological tool to guide emergency response and loss estimation for public information through emergency response networks, the Internet, and the media.

Figure 1 shows a ShakeMap based on magnitude and epicenter. The data used to produce the ShakeMap are collected by nine strong motion records around the epicenter which have located in Iran and are improved with felt intensity data of 10 places. The PGA and PGV ShakeMaps generated by IIEES are shown in Figures 2 and 3.The average value and the corresponding letter grade is displayed on the bottom left of the uncertainty map (Figure 4).
