Keynote from the Raffles Science Symposium
Finding Faults: Identifying Earthquake Hazards Around the World
Asst. Prof. Judith Hubbard
Division of Earth Sciences and Earth Observatory of Singapore, NTU
Many earthquakes occur on faults that have not ruptured for hundreds, or even thousands, of years. As a result, earthquakes sometimes seem unexpected, causing massive devastation in areas that are not adequately prepared. How can we identify active faults before they slip and evaluate their earthquake hazard, and why is earthquake prediction so difficult? Prof. Judith Hubbard will discuss how earth scientists use cutting-edge techniques, such as subsurface imaging, 3D visualization, geophysical modeling, and remote sensing, to better understand and forecast earthquakes in areas ranging from Sichuan, China, where a M7.9 earthquake killed 80,000 people in 2008, to Ventura, California, where she predicts that a similar magnitude earthquake may occur in the next few centuries.

About Prof. Hubbard:
Prof. Judith Hubbard studies earthquake hazards with the goal of better understanding and preparing for damaging earthquakes. She uses surface and subsurface data from a variety of sources, including satellite imagery, geological investigations, and petroleum industry seismic reflection and well data, to assess the 3D geometries and kinematics of active faults. She received her Ph.D. in 2011 from Harvard University and her B.S. in 2005 from the California Institute of Technology. She joined the faculty at the Earth Observatory of Singapore at Nanyang Technological University in September 2012, and plans to develop a field and laboratory research program that will focus on active faults in many part of Southeast Asia, including Sumatra, Bangladesh, Myanmar, and northern India.
