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

<p>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.</p> <p>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 (&#39;vertical_Z&#39;), eastwards (&#39;horizontal_E&#39;), and northwards (&#39;horizontal_N&#39;).</p> <p>The respective source position is stored in &#39;source.txt&#39; and the measurement positions in &#39;stations.txt&#39;. The &#39;traces&#39;-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&nbsp; (m) | North s_Y (m) | Vertical s_Z (m)| East v_X&nbsp; (m/s) | North v_Y (m/s) | Vertical v_Z (m/s)</p> <p>Sampling frequency: 100Hz</p>
