Abstract

In studies of crustal deformation, volcanic models give valuable insights of volcanoes features and their behavior over time. DISPLACEMENT FIELD MODELING, using analytical models needs to determine the parameters of the geophysical and geological volcanic reservoir. Therefore, modelling of volcanic magma reservoir was performed by an inverse problem resolution using the displacement field obtained from geodetic observations as the boundary values of the analytical models of deformation. This modeling was performed by genetic evolutionary OPTIMIZATION algorithm for DAMAVAND VOLCANO. Also, Displacement field during the years 2000 to 2001 for campi flegrei volcano was modelled. Comparing with the previous studies, the research has demonstrated favorable results. The result of displacement field modelling of the DAMAVAND VOLCANO has shown unexpected residuals (according to the magnitude of the displacement field) in some areas. This fact indicates presence of other displacement sources in addition to the volcanic deformation source in the region. The results lead to a reduction in the volume of the volcano magma reservoir with rate of equal to 0.001, located at a depth of 5.6 km below the ground. This volume reduction causes a small displacement in the area near the volcanic source. Modelled 2D coordinate of center of the source in the Lambert projection (4831.999E, 31328.536N) km and RMSE of inversion results 2mm was achieved.
