Reciprocal SEM simulations of seismic impulse response at Piton de la Fournaise volcano

This Dataset contains synthetic seismic signals simulated using the Spectral Element Method (SEM) for the study of rockfall seismic signals at Piton de la Fournaise volcano. Synthetic signals from both a reference model with flat surface and a model with Dolomieu crater surface topography of 10m resolution are contained. The simulations were carried out reciprocally for seismometers BON, BOR, DSO and SNE, implementing surface point force in form of a 7Hz Ricker wavelet directed vertically ('vertical_Z'), eastwards ('horizontal_E'), and northwards ('horizontal_N'). The respective source position is stored in 'source.txt' and the measurement positions in 'stations.txt'. The 'traces'-folder contains a file corresponding to each station with 7 columns including simulation time t, ground displacement s and ground velocity v:<br> Time t (s) | East s_X (m) | North s_Y (m) | Vertical s_Z (m)| East v_X (m/s) | North v_Y (m/s) | Vertical v_Z (m/s) Sampling frequency: 100Hz
