Overview

This team's research combines traditional geological tools, like geological maps, satellite imagery, and seismicity datasets, with data from the oil industry (seismic reflection data and wells). In addition, Judith Hubbard's team bought an Envirovibe minibuggy from Industrial Vehicle International to acquire high-resolution seismic reflection data across the tips of active faults to understand their recent deformation history and to tie deep structure to surface deformation.

Many active fault systems in Southeast Asia are barely mapped, and the region thus offers many open research problems; it is one of the best places in the world to study earthquake hazards today. Judith Hubbard's team will use quantitative fault-related folding techniques to interpret datasets at its disposal and develop realistic geometric and kinematic 3D fault models. The lab will develop local and regional 3D fault models for parts of Southeast Asia, including fault systems in the Himalayas, Myanmar and Bangladesh.
