ABSTRACT
Ankara, the capital city of Turkey has been suffered by serious terrorist attack in last six months in 2015-2016 resulted 170 death and 685 injuries. These blasts produced seismic signals which were recorded by three broadband instruments; ODTU, ANTO and LOD. Analysis of the seismic signals show that, (1) the first blast could not generate enough radiated energy to analysis because of less amount explosive materials carried by two suicide bombers, (2) the second event was a massive single event caused by a car loaded bomb, (3) the third event consists of two blast with 0.3 sec time interval caused by a car bomb and the car bomb was moving north-south direction just before explosion. The results of short time Fourier analysis indicate that the energy releases focused at higher frequencies around 13-25 Hz. Even though most of energy radiated to atmosphere as the healing energy, calculating energy amount using seismic signals suggest that 1.04e+7, 4.21e+7 and 8.16e+7 joule energy radiated in crust for 10 October, 2015, 17 February, 2016 and March 13, 2016 attacks, respectively.
