Ever since the 1990s, IPGP has been contributing to the scientific cooperation with Indonesia, on programs dedicated to volcanic activity, more specifically on the Merapi volcano, through studies on deformations (GPS, tiltmeters, strainmeters). Since 2012, the IPGP teams from the Seismology and Volcanic Systems research departments  have been involved in the ANR- funded Domerapi project (in collaboration with  ISTerre, IPGP, LMV, ISTO, IRD, GFZ, USGS). The purpose is a better understanding of the deep and surface magmatic processes on one of the most explosive and active volcanoes in the world.  The seismology research team has set up a new permanent GNSS network on the Merapi volcano (Java island) combined with the analysis and real-time numerical modelling of the deformation source and multi-parameter stations (in collaboration with ISTerre) around the new crater formed following the major 2010 eruption. A tiltmeter prototype specially designed for strato-volcano ground coupling using shallow boreholes, has been installed on 3 sites of Merapi volcano and on one site of the Dukono volcano (North Maluku).

This worksite contributes to the development of the WebObs system through its monitoring of active volcanoes on the Indonesian Archipelago.
