The geologic features and seismic activity in the Himalayas and Pacific Northwest could mean those areas are primed for major earthquakes.
Scientists have known for some time that India is subducting under Asia, and have recently begun studying the complexity of this volatile collision zone in greater detail, particularly the fault that separates the two plates, the Main Himalayan Thrust (MHT).
“What we’re observing doesn’t bear on where we are in the earthquake cycle, but it has implications in predicting earthquake magnitude,” says Warren Caldwell, a geophysics doctoral student at Stanford University. “From our imaging, the ramp location is a bit farther north than has been previously observed, which would create a larger rupture width and a larger magnitude earthquake.”
