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 …

With the gradual development of and improvement in earthquake early warning systems
(EEWS), more accurate real-time seismic intensity measurements (IMs) methods are needed …

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 …

The 26 August 2012 Brawley seismic swarm of hundreds of events ranging from M1. 4 to
M5. 5 in the Salton Trough, California provides a unique data set to investigate a new …

The scaling of rupture properties with magnitude is of critical importance to earthquake early
warning systems that rely on source characterization using limited snapshots of waveform …

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

Scenario ruptures and ground motion simulation are important tools for studies of expected
earthquake and tsunami hazards during future events. This is particularly important for large …

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 …

ABSTRACT A prototype earthquake early warning (EEW) system is currently in development
in the Pacific Northwest. We have taken a two‐stage approach to EEW:(1) detection and …

Displacement waveforms derived from Global Navigation Satellite System (GNSS) data
have become more commonly used by seismologists in the past 15 yrs. Unlike strong …
