Seismological Computing Center

Physics Today, 1963
The University of Edinburgh has received a grant of $280 700 from the US National Science Foundation to assist in establishing a seismological computing center within the University's Department of Astronomy. The NSF grant will be supplemented by £10 000 capital and £6500 recurrent from the British Treasury.

The Spectral-Element Method, Beowulf Computing, and Global Seismology

Science, 2002
The propagation of seismic waves through Earth can now be modeled accurately with the recently developed spectral-element method. This method takes into account heterogeneity in Earth models, such as three-dimensional variations of seismic wave velocity, density, and crustal thickness.

A Suite of Educational Computer Programs for Seismology

Seismological Research Letters, 2003
A set of four, public-domain, educational computer programs have been developed that assist a student in learning about earthquakes. These programs are: The programs run under Windows®. They are available at http://www.geol.binghamton.edu/faculty/jones.

Requirements Engineering for Computational Seismology Software

2013
Many seismological software applications are developed to support for instance studies of earthquake scenarios, seismic exploration surveys or hazard analysis. Most of these applications were developed in isolation with focus on algorithmic performance, and less emphasized on software’s comprehensibility and maintainability.

Origin of interactive computer graphics in seismology

The Leading Edge, 1991
Ivan Sutherland’s Sketchpad, completed in 1962 and published in 1963, is routinely cited as the first interactive‐computer system and causes Sutherland, who developed it for his doctoral dissertation at MIT, to be acknowledged by many authorities as the inventor of computer graphics.

GCLgrid: A three-dimensional geographical curvilinear grid library for computational seismology

Computers & Geosciences, 2006
We developed a general library for handling a class of objects we call geographical curvilinear grids (GCLgrids). A GCLgrid is a distorted, uniform grid that is georeferenced. The GCLgrid library is implemented in an object oriented system with methods that relate points in the grid to a geographic reference frame. A simple example is a spherical shell

Dawn of a New Era in Computational Global Seismology

Seismological Research Letters, 2001
Global seismology is a science driven by observations, and most major advances in our discipline can be linked to advances in the quality and quantity of seismic instrumentation. Normal-mode seismology was born in the early Sixties, when Caltech and UCLA seismologists identified fundamental toroidal and spheroidal modes in spectra obtained from time ...

NBW: Computational Seismology: Narrowing the Gap Between Theory and Observations

2005
Numerical solutions to the problem of seismic wave propagation, that allow simulations of complete wave fields through 3D structures, are currently revolutionizing seismology and related fields. So far - in order to calculate theoretical seismograms in the observed frequency bands - one had to resort to solution methods with severe limitations (e.g ...

The Orfeus Java Workshop: Distributed Computing in Earthquake Seismology

Seismological Research Letters, 2000
Back in May 1997 the Electronic Seismologist (ES) attended a workshop with all sorts of seismo-computer geeks and nerds discussing the future direction of seismological software development. A rambling report on this workshop (“The Electronic Seismologist goes to FISSURES”, Malone, Seism. Res. Lett. 68 (4), 1997) concluded that a new approach to future

Numerical modeling of attenuation and non linear effects in computational seismology

2020
<p>We solve elastic waves equations in 2D/3D using a fourth order in time and space finite volume method based on exact Riemann solver and wave limiters and designed particularly to capture shock waves.  We validate our code by comparing our results with spectral elements solutions (SPECFEM). </p ...
