Algorithm ATOM-3D oriented on investigation of 3D velocity structure based on 3D distribution of artificial sources and station. Below is an example of synthetic modeling for a realistic observation scheme in Canaries.
Figure 1. Locations of stations (onshore) and sources (offshore) in a real 3D seismic experiment in Canaries.
Figure 2. Result of reconstruction of Simon Bolivar synthetic model. The “true” model is shown in the upper left plot and represented by complex prisms with positive and negative anomalies which remain unchanged in all depths. The other plots are the inversion results for the depths of
0, 3 and 6 km. This test shows fairly good horizontal resolution provided by this observation scheme which allows investigating fine volcano structure.

Figure 3. Investigating vertical resolution provided in the Canaries experiment. Upper plots show the map view of the “true” model (left) and reconstruction results (right) at the depths of 0 and 5 km. Lower plots represent the synthetic model (upper) and reconstruction result (lower) in vertical section. We can see that the algorithm resolve the interface at 2 km depth beneath the onshore part. In general, the vertical resolution is lower than the horizontal one.
