Volatiles are a key component of volcanic activity. The amount of volatiles, depth of magma storage, and ascent rate likely control the variety of eruption styles. Magmatic gases released to the atmosphere during large explosive eruptions can have significant impact on earth’s climate.... Read more

Chemical and textural zoning in crystals from volcanic rocks can be used to fingerprint the processes that lead to magma storage and eruption, but decoding the crystal record is not straightforward. In the last three years, we have developed new statistical tools and software based on... Read more

Petrological studies can inform of the processes and time scales of magma movement and ascent, and thus allow associating them with monitoring unrest signals, and thus better mitigate volcano hazards. This year we made significant progress in linking time scales and monitoring data for Kelut... Read more

Past Projects

A long-standing goal of volcanology is to forecast eruptions as accurately as possible. monitoring data allows operational short-term forecasts for getting people of harm's way, but only through understanding how the inner parts of volcanoes work can we expect to move towards science-based long...

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... Read more

Subsidiary Projects:

Chemical zoning in crystals may result from a variety of magmatic processes, and it can be interpreted as due to changes in the main intensive variables (e.g. pressure, temperature, chemical potential). Mineral zoning can, therefore, be treated as a valuable source of information about the... Read more
