An extended reflectivity method is described by which complete seismograms for a point
source in a layered half-space can be calculated. Starting with the differential equations and …

An Introduction to Seismology, Earthquakes and Earth Structures is an introduction to
seismology and its role in the earth sciences, and is written for advanced undergraduate and …

Synthetic seismograms, computed for realistic, horizontally stratified media, are now
routinely used as an aid to seismic interpretation. This paper reviews the theoretical …

Seismic body waves that sample Earth's core are indispensable for studying the most
remote regions of the planet. Traditional core phase studies rely on well‐defined earthquake …

The Earth's solid inner core exhibits strong anisotropy,,,,, with wave velocity dependent on
the direction of propagation due to the preferential alignment of iron crystals. Variations in …

We develop an algorithm to detect and locate sources of long‐period (25–100 s) seismic
signals. Our method is based on the analysis of seismological data recorded at global …

The first part of this article gives new travel-time data for the phase PKiKP at subcritical
distances (Δ< 110°) obtained at the Warramunga array in Northern Australia. A compilation …

In this study, we analyze continuous data from all Global Seismographic Network stations
between year 2000 and 2009 and demonstrate that several body wave phases (eg, PP …

Abstract Recent work by Braun, Duvall, and LaBonte has shown that sunspots absorb
helioseismic waves. We propose that sunspot absorption causes a seismic deficit that …

PKP (BC) versus PKP (DF) differential travel times show coherent patterns of residuals
indicating aspherical structure within the Earth's inner core. Using a waveform correlation …
