Summary The International Seismological Centre (ISC) is a non-governmental, non-profit
organization with the primary mission of producing the definitive account of the Earth′ s …

A large number of fundamental-mode Love and Rayleigh wave dispersion curves were
determined from seismograms for 3330 earthquakes recorded on 258 globally distributed …

We develop a regional seismic travel-time (RSTT) model and method for use in routine
seismic analysis. The model parameterization is a global tessellation of nodes with a …

Event-pair double-difference (DD) earthquake location method, as incorporated in hypoDD,
has been widely used to improve relative earthquake locations by using event-pair …

Ground truth seismic sources and receivers are the seismologist's equivalent of the
geodesist's “benchmark.” Geodesists measure distances between benchmarks on the …

We construct a model of three‐dimensional P wave velocity structure in the crust and mantle
that is global in extent, but with detailed upper mantle heterogeneities throughout the greater …

This paper details the evolution, precision and completeness of the earthquake catalogue
compiled by the Spanish National Geographic Institute. Over 100,000 earthquakes are …

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 …

A key ingredient in understanding Earth structure is the integration of seismological
information with results from mineral physics for both the dominant radial dependence of …

Correlated travel-time errors bias both seismic location and location uncertainty estimates.
Methodologies are introduced to model travel-time correlation structures and to account for …
