Abstract

Telah dilakukan pemodelan receiver function untuk data teleseismik yang direkam oleh stasiun pengamatan gempabumi 3 komponen. Perhitungan dekonvolusi dalam perhitungan receiver function ini dilakukan dalam domain frekuensi. Pemodelan dilakukan dalam sistem MATLAB. Program dapat berjalan dengan efisien, dan waktu yang diperlukan untuk perhitungan untuk model 4 lapis adalah sekitar 1,2 detik dengan menggunakan komputer Intel Atom dengan memori 1 GB. Untuk model dengan 31 lapisan, diperlukan waktu perhitungan 1,9 detik. Efektifitas program ini memungkinkan untuk dikembangkan lebih lanjut misalnya untuk keperluan inversi.

 

Receiver function modeling for teleseismic earthquake has been implemented using MATLAB. The deconvolution process is carried out in the frequency domain for simplicity. The time required for calculating a four-layer model is about 1.2 seconds using Intel Atom 1 GB of memory. For a velocity model with 31 layers it takes 1.9 seconds using the same computer specification. The effectiveness of the program may used for other advance application especially for earth crustal inversion.
