Determination of Cerro Blanco volcano deformation field using method of fundamental solutions

According to geodetic research works, surface deformation in the form of uplift or subsidence in volcanic areas is either a sign of magma moving towards the opening of the volcano (inflation) or removal of the magma source (deflation). Using the new method of fundamental solutions (MFS) in this stud...
