Prof Christopher George NewhallI'll be helping to build the volcanology research group here at NTU, with close links to researchers and practitioners in neighboring volcanic countries. Our main focus will be eruption forecasting, and understanding magmatic plumbing and processes toward that goal. We'll be developing new tools for forecasting -- new research insights, new equipment, and WOVOdat, a new database of worldwide volcanic unrest among them. Since volcano research needs to start on real volcanoes, and Singapore doesn't have any, we plan "laboratory volcano" projects in the Philippines and Indonesia that will decipher eruptive history and current/future unrest, and also serve as a test ground for new tools. My own research will emphasize the ways by which magma degasses ("loses its fizz"), ways in which magma interacts with groundwater, and "epidemiological" mining of WOVOdat. Our work needs small, low-power, inexpensive, and unobtrusive (hard for passerbys to see) power and radio telemetry for remote stations on volcanoes. We need innovative new ways to "see" stress conditions, magmatic gas pressures, and groundwater pore pressures inside volcanoes, and more robust, cheaper ways for continuous, multi-species volcanic gas monitoring. And we need to improve real-time detection and characterization of ash clouds that threaten aviation, and fragility curves of damage to aircraft from various concentrations and exposure to ash. The closeness to nature, camaraderie, and both intellectual and physical challenges of working on volcanoes are infectious! Join us! I welcome students and collaborators from various disciplines who are interested to apply their insights to problems of volcano monitoring, volcanic behavior, and risk mitigation. Please contact me with your volcano questions and interests!

Prof Kerry Edward SiehMy principal research interest is earthquake geology, which uses geological layers and landforms to understand the geometries of active faults, the earthquakes they generate, and the crustal structure their movements produce. My early work on the San Andreas fault led to the discovery of how often and how regularly it produces large earthquakes in southern California. More recently, my students and colleagues and I investigated Taiwan's multitude of active faults and figured out how their earthquakes are creating that mountainous island. We are currently exploring the earthquake geology of Myanmar (Burma). Our principal current research interest is the subductionmegathrust that produced the devastating giant Sumatran earthquakes and Indian Ocean tsunamis of 2004 and 2005. That research suggests that the megathrust is poised to produce yet another giant earthquake in western Sumatra. I am also now involved in creation of the Earth Observatory of Singapore, which aims to conduct basic and applied research related to earthquake, tsunami, volcanic, and climate hazards.
