Geodesy, the oldest science, has become an important discipline in the geosciences, in
large part by enhancing Global Positioning System (GPS) capabilities over the last 35 years …

The discovery of slow-slip phenomena has revolutionized our understanding of how faults
accommodate relative plate motions. Faults were previously thought to relieve stress either …

Slow earthquakes represent an important conundrum in earthquake physics. While regular
earthquakes are catastrophic events with rupture velocities governed by elastic wave speed …

Much of the world's known gold has been derived from arrays of quartz veins. The veins
formed during periods of mountain building that occurred as long as 3 billion years ago …

Nonvolcanic tremor is observed in close association with geodetically observed slow-slip
events in subduction zones. Accumulating evidence points to these events as members of a …

Many types of hydrothermal ore deposits form at overpressured conditions during high fluid
flux through fault zones in the continental seismogenic regime. These include many …

Advances in observational, laboratory, and modeling techniques open the way to the
development of physical models of the seismic cycle with potentially predictive power. To …

Detection of low magnitude event is critical and challenging in seismology. We develop a
new method, named the match and locate (M&L) method, for small event detection. The M&L …

We report on laboratory experiments designed to investigate the influence of pore pressure
oscillations on the effective permeability of fractured rock. Berea sandstone samples were …

The passage of radiating seismic waves generates transient stresses in the Earth's crust that
can trigger slip on faults far away from the original earthquake source. The triggered fault …
