Last December, the Earth Observatory of Singapore (EOS) celebrated the 10th anniversary of its collaboration with the Centre for Volcanology and Geological Hazard Mitigation (CVGHM).
The development of increasingly precise geophysical monitoring tools has led to progress in the field of eruption forecasting, but predicting the size and vigor of an eruption remains a major challenge in the assessment of risks. The vast majority of active volcanoes display wide ranges in eruption styles over long and short time scales, from effusive lava flows or dome growth to explosive Strombolian, Vulcanian, or Plinian eruptions. The long term goals of my group are to shed light on the combinations of processes and physical parameters that govern the magnitudes and styles of eruptions, and to enhance our ability to interpret geophysical and geodetic monitoring signals in terms of magmatic processes.
Our main research interests, therefore, focus on:
In addition, the fact of addressing these questions may also bring elements of response to more petrology-based problems such as: How to reconcile the plutonic and volcanic record? How and where do magmas differentiate (e.g. assimilation vs. fractional crystallization)? How do the transport, accumulation, and differentiation of magma affect the formation of continental crust?

If a volcano is rumbling then we can expect an eruption, but how big will that eruption be? Currently we have little idea of how to forecast the size of future eruptions.
Sumatra hosts the volcanoes closest to Singapore and is home to some of the largest eruptions in the world. This project is the first step of a long-term effort directed towards a detailed assessment of the hazard related to Sumatran volcanoes....
We conduct a multidisciplinary study which investigates conduit and reservoir bubble dynamics through a combination of petrology, geochemistry, textural analysis, and numerical modeling.
