Recent technological advances have revolutionized volcano monitoring by improving our ability to measure changes of a volcanic system before, during, and after an eruption. However, it remains a challenge to relate the monitoring signals to the magmatic system and processes occurring at depth.

Hence, Fidel Costa’s research group uses micro and nano-analytical techniques, thermodynamics, and kinetic models to reconstruct the plumbing system and produce a time series of magmatic events leading to eruptions. Main targets are the EOS laboratory volcanoes of Mayon and Gede-Salak.
