Call her a nerd, but earthquake scientist Judith Hubbard loves geology, and she is not afraid to admit it.
Geology is all around us, evident to those who care to look, like...
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
In 2014 and 2015, the Structural Geology group at EOS conducted seismic reflection acquisition in Nepal across the Main Frontal Thrust to constrain its geometry and kinematics.
The Longmen Shan mountain range, site of the devastating 12 May 2008 Wenchuan (Mw7.9) earthquake, defines the eastern margin of the Himalayan orogen and exhibits greater topographic relief than anywhere else in the Tibetan plateau.
The 2008 Mw7.9 Wenchuan earthquake ruptured an imbricate thrust system in the Longmenshan range, which forms the eastern boundary of the Tibetan Plateau.
The Ventura Avenue anticline is one of the fastest uplifting structures in southern California, rising at ∼5 mm/yr. We use well data and seismic reflection profiles to show that the anticline is underlain by the Ventura fault, which extends to...
The goal of our research is to understand the geometries and activities of faults in the Longmenshan and Sichuan basin in order to assess the regional seismic hazard.
This project aims to study the MFT and its associated fault splays by acquiring a densely-spaced set of high-resolution seismic reflection profiles across the fault tip in order to assess the geometry and kinematics of the fault.
