| Abstract | : | The spectral-element method (SEM) has been applied to simulate seismic wave propagation in 2D tentative geological model of Geothermal Area in Tiris, East Java Indonesia. We used 2-D model with 36 km x 5 km dimensions and discretized into 720 × 80 rectangular elements (mesh). We computed 8000 time steps with a sampling interval of 0.001 s using 10 Hz Ricker wavelet. The snapshots of seismic wave propagation along Tiris 2D geological model illustrate that SEM could accurately modeling seismic wave propagation. The seismic event that triggers a vibration in rock layers not only depend on the characteristics of the seismic earthquake source parameters and seismic wave propagation media, but also influenced by geometry of the media, such as topography and geological setting. The influence of ground topography, difference media, and structural geology were demonstrated by different time of wave arrival and different amplitudes. Therefore, SEM could be applied as preliminary study in geothermal exploration |
