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 aim of the Volcanic Petrology group is to conduct fundamental research on magmatic processes and rocks from active volcanoes, toward better understanding and forecasting of volcanic eruptions.
Some of our underlying research questions include
The signature and strength that distinguishes this group from others worldwide is that we focus our research on deciphering the time scales for all of these processes.
Some of our research tools include:
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.
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.
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.
