1. XML-SEED format and its application to synthetic seismogram database Seiji Tsuboi IFREE/JAMSTEC

2. XML Representation of SEED format eXtensible Markup Language (XML) is a text-based language. XML documents use `tags’ to establish hierarchical data structure and named values. XML can be used for most of all major platforms. XML is a basic technology for networking.

3. Advantages of using XML Header structure of SEED is modular, which can be easily represented by XML. Data structure of XML is flexible, because length of any fields is not fixed. XML has its schema language –XML- Schema, which can be used for validation of XML document.

4. SEED Format Organization Control headers (formatted in ASCII) information about the volume, the station- channels, and the data Time series (binary, unformatted) seismic waveform data

7. Synthetic seismogram database Synthetic seismograms, which are accurate up to 5 sec and longer, will be calculated by Spectral-Element Method on the Earth Simulator for fully 3-D Earth model. Database will be created for all the broadband seismograph stations over the globe. Minimum magnitude of the earthquake will be chosen considering the available CPU time (currently Mw>6.5).
