Pg waves, which propagate at high frequencies through the crust, are important for tomography and explosion monitoring, and can be among the most prominent P waves observed from small seismic events. Much of what we know about Pg propagation, however

The regional seismic travel time (RSTT) model and software were developed to improve travel-time prediction accuracy by accounting for three-dimensional crust and upper mantle structure. Travel-time uncertainty estimates are used in the process of as

A function of global monitoring of nuclear explosions is the development of Earth models for predicting seismic travel times for more accurate calculation of event locations. Most monitoring agencies rely on fast, distance-dependent one-dimensional (

A fundamental component of seismic research is the use of phase arrival times, which are central to event location, Earth model development, and phase identification, as well as derived products. Hence, the accuracy of arrival times is crucial. Howev

The task of monitoring the Earth for nuclear explosions relies heavily on seismic data to detect, locate, and characterize suspected nuclear tests. Motivated by the need to locate suspected explosions as accurately and precisely as possible, we devel

Blast waves produced by 60 high-explosive detonations were recorded at short distances (few hundreds of meters); the corresponding waveforms show charge-configuration independent coda-like features (i.e., similar shapes, amplitudes, and phases) lasti

Tsunami earthquakes, events that generate larger than expected tsunami and are deficient in high frequency seismic radiation, are rare but hazardous to coastal populations. One model for these events is shallow rupture through low strength materials.

Reliable use of regional seismic phases for discrimination and magnitude estimation requires accurate corrections. Procedures that simultaneously invert for source, attenuation ( Q ), spreading, and site parameters have trade‐offs that result in la

Fisk and Phillips (2013) motivated the need to constrain trade‐offs among correction parameters for regional phase amplitudes to improve seismic discrimination and magnitude (yield) estimation. Using an empirical Green’s function approach to canc
