AB: A combined inversion of gravity changes, height, and radial displacements, which were measured in the period between 2000 and 2002 at Merapi volcano, Java, Indonesia, provides the possibility for the detection of potential magma/pressure sources which might be responsible for the temporal displacement and gravity changes. The combined inversion technique is based on the Navier-Stokes equation that couples elastic and gravitational effects in a mathematical halfspace. The most reliable sources found (both magma and pressure) are the results of global optimization using genetic algorithm techniques.
