Daftar Isi:
- It has been done analysis f-k of MERAMEX data at Yogyakarta. The purposes of this analysis are to identify shallow P-wave velocity structure in Yogyakarta that can be used to mitigation of natural disaster, especially earthquake. F-k method calculating the energy that is distributed between slowness and the propagation of earthquake wave. The wave is received at least 4 station receiver that placed at earth surface. The frequency analyzed using software Geopsy, Dinver, and Surfer. The results of f-k show that there is closure in Yogyakarta. A high vp located around CJ3 arrays station, with an average vp of 3835 m/s which is located in the northeast research area. Low vp is in the center of Yogyakarta with vp 400-1200 m/s with north-south directional. A high vs around AK2 arrays station. At this station has an average vs of 770 m/s whereas low vs located in the center of Yogyakarta with vs 150-250 m/s.
