SPECFEM3D_GLOBE simulates global and regional (continental-scale) seismic wave propagation.

Effects due to lateral variations in compressional-wave speed, shear-wave speed, density, a 3D crustal model, ellipticity, topography and bathymetry, the oceans, rotation, and self-gravitation are all included.

The version 7.0 release offers GPU graphics card support for both OpenCL and CUDA hardware accelerators, based on an automatic source-to-source transformation library (Videau et al. 2013). It offers additional support for ADIOS file I/O formats and contains important bug fixes related to 3D topography and geographic/geocentric transformations. Seismogram file names adapt a new naming convention, with better compatibility to the seismogram specifications by the Incorporated Research Institutions for Seismology (IRIS).

An interactive visualization of earthquake seismic waves traveling through the Earth's interior and radiating outward on the surface and simultaneously being recorded on seismograms. Choose from 10 major earthquakes. Hosted by the Incorporated Research Institutions for Seismology (IRIS).

This paper describes the tectonic summaries for all magnitude 7 and larger earthquakes in the period 2000–2015, as produced by the U.S. Geological Survey National Earthquake Information Center during their routine response operations to global earthquakes. The goal of such summaries is to provide important event-specific information to the public rapidly and concisely, such that recent earthquakes can be understood within a global and regional seismotectonic framework. We compile these summaries here to provide a long-term archive for this information, and so that the variability in tectonic setting and earthquake history from region to region, and sometimes within a given region, can be more clearly understood.

This a collection of tools to run HypoDD by Felix Waldhauser. It takes event files in the QuakeML format, station data in the SEED format and waveform data in any format ObsPy can read and does all the rest. The output is one QuakeML file with the relocated events having one additional Origin node. The events that could not be relocated will not be changed.

This tutorial shows how to acquire earthquake waveforms from data centers. The data centers are used to provide SEED volumes for regional moment tensor inversion.

Our mission is to maintain an easily-accessible, well-organized, high-quality, searchable archive of earthquake data from southern California for research in seismology and earthquake engineering. Find research tools, general earthquake information, stations/instrumentation, and educational resources.
