**Résumé (en anglais)
This project is focused on Merapi, the most active volcano of Indonesia. This project provides the opportunity to investigate the transition between moderate and violent explosions related to dome growth and collapse and the longterm impacts of such an event on dome-forming type volcanoes. To reach that goal, the permanent monitoring system must be implemented with a dense multiparametric network of sensors with cutting-edge technology, making Merapi one of the best monitored volcanoes in the world. The results will have major implications for understanding magmatic processes, volcanoe monitoring, hazard assessment and risk reduction on other explosive island-arc volcanoes, such as the French volcanoes in the West Indies.
