Standards and formats
Seismic Data Formats
ISF is the IASPEI approved standard format for the exchange of parametric seismological data (hypocentres, magnitudes, phase arrivals, moment tensors, etc.). It was adopted as standard in August 2001 by IASPEI's Commission on Seismic Observation and Interpretation at the Scientific Assembly in Hanoi, Vietnam. The format is an extenstion of IMS1.0. The full documentation may be downloaded for both ISF (pdf) and IMS1.0 (pdf)
ISF 2 (IASPEI Seismic bulletin Format)
There has been a need to add a number of data types to ISF 1 for sometime, this has lead to the development of ISF 2. The format is an extension of ISF 1 as all additional data is in extensions to the existing ISF 1 formats. The changes chiefly are improved data attribution through extended station details and channel information for phases and amplitude.
The full documentation can be seen here ISF2 (pdf).
QuakeML is a flexible, extensible and modular XML representation of seismological data. The full documentation may be found at https://quake.ethz.ch/quakeml/.
GSE2.1 FormatGSE2.1 was first developed for use in the GSE's Technical Test 3 (GSETT-3), which was a trial starting on 1st January 1995 for a system of global monitoring of nuclear explosions. Based on experience during GSETT-3, a new format was developed for use with the International Monitoring System (IMS) of the Comprehensive Nuclear Test Ban Treaty.
Documentation for GSE2.1 can be found at http://www.seismo.ethz.ch/prod/autodrm/provisional_GSE2.1.pdf as part of the AutoDRM documention.
