Standards of the DS Bulletin

To assure and maintain the highest quality and the standard for parametric data exchange , DS Bulletin procedure follows the IASPEI standards and requirements as implemented at International Seismological Centre (ISC) data flow and processing pipe-line and criteria for parametric seismic data review. The above standards are guaranteed by the actual data flow and processing managed through SEISAN (http://seisan.info/) and Seiscomp4 ( https://www.seiscomp.de/), strictly following the IASPEI Phase data format (http://www.isc.ac.uk/standards/phases/) and Magnitude standards (http://www.isc.ac.uk/standards/magnitudes/), as described in the following references:

Parametric seismic data formats used by DS (IGEO) are Nordic, QuakeXML and ASCII.

NORDIC format was one of the first attempts to create a more complete format for data exchange and processing. The initiative came from the need to exchange and store data in Nordic countries and the so called Nordic format was agreed upon among the 5 Nordic countries. The format later became the standard format used in the SEISAN database and processing system and is now widely used.
QuakeML is a flexible, extensible and modular XML representation of seismological data. The full documentation may be found at https://quake.ethz.ch/quakeml/.
ASCII stands for the "American Standard Code for Information Interchange".
It was designed in the early 60's, as a standard character set for computers and electronic devices.
ASCII is a 7-bit character set containing 128 characters.
It contains the numbers from 0-9, the upper and lower case English letters from A to Z, and some special characters.
The character sets used in modern computers, in HTML, and on the Internet, are all based on ASCII.
