The Global Centroid Moment Tensor (GCMT) is a seismological and geophysical database of locations and source parameters for globally recorded earthquakes larger than magnitude 5.0. GCMT's primary goals are determination of moment tensors for major earthquakes globally and quick dissemination of results.
IRIS programs contributed to scholarly research, education, earthquake hazard mitigation, and the verification of a Comprehensive Nuclear-Test-Ban Treaty. Support for IRIS came from the National Science Foundation, other federal agencies, universities, and private foundations. IRIS supported five major components: The Data Management Center ...
The main scientific goal of the centre is the definitive compilation of earthquake information and the readings on which they are based. Collection of reports of earthquake effects is also an important part of its operation and the Centre recomputes the location and occurrence time of earthquakes worldwide, making use of all available information.
QuakeSim is a NASA project for modeling earthquake fault systems.It was started in 2001 with NASA funding as a follow-up to the General Earthquake Models (GEM) initiative. The multi-scale nature of earthquakes requires integrating data types and models to fully simulate and understand the earthquake process.
The list incorporates high-quality earthquake source (i.e., origin time, location and earthquake magnitude) and fatality information from several sources. Earthquake locations are taken from the Centennial Catalog [1] and the updated Engdahl, van der Hilst and Buland earthquake catalog, [2] which is complete to December
Version 1.2 is the latest stable version QuakeML. Schemas and other documentation for version 1.2 can be found here. This is the version that is used in results of event queries to International Federation of Digital Seismograph Networks (FDSN) web services and is supported by data centers around the world, such as the European Seismic Portal.
The USGS informs authorities, emergency responders, the media, and the public, both domestic and worldwide, about significant earthquakes. It maintains long-term archives of earthquake data for scientific and engineering research. It also conducts and supports research on long-term seismic hazards.
According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
