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 …

Charles Richter's observation that'only fools and charlatans predict earthquakes,'reflects the
fact that despite more than 100 years of effort, seismologists remain unable to do so with …

GPS instruments are noninertial and directly measure displacements with respect to a global
reference frame, while inertial sensors are affected by systematic offsets—primarily tilting …

Abstract The 2015 Mw8. 3 Illapel, Chile earthquake is the latest megathrust event on the
central segment of that subduction zone. It generated strong ground motions and a large (up …

Subduction zone earthquakes result in some of the most devastating natural hazards on
Earth. Knowledge of where great (moment magnitude M≥ 8) subduction zone earthquakes …

Rapid and reliable estimation of large earthquake magnitude (above 8) is key to mitigating
the risks associated with strong shaking and tsunamis. Standard early warning systems …

Rapid near‐source earthquake source modeling relying only on strong motion data is
limited by instrumental offsets and magnitude saturation, adversely affecting subsequent …

The combination of GPS and strong‐motion data to estimate seismogeodetic waveforms
creates a data set that is sensitive to the entire spectrum of ground displacement and the full …

To contribute to tsunami early warning systems, we investigated the currently achievable
speed of tsunami inundation simulations on a parallel computer as well as the benefits of …

Natural hazards including earthquakes, volcanic eruptions, and tsunamis have been
significant threats to humans throughout recorded history. Global navigation satellite …
