Preliminary IASPEI GT reference events: bulletin search
This page is used to search the IASPEI Reference Events database to output a full event bulletin in either IASPEI Seismic Format (ISF) or as an XML stream.
About the bulletin search
Use this search to output all available data within the IASPEI Reference Events List. This includes access to the IASPEI GT location and any ISC hypocentre solution, magnitude values, phase data, etc.Output format
- ISF Bulletin:
- QuakeML:
The IASPEI Seismic Format (ISF) is a fixed format bulletin. Further information about the format, versions and links to the full documentation can be found on the ISF page.
QuakeML is an XML representation of seismological data. Data are output as an XML stream using the QuakeML XML Schema, version 1.1. QuakeML has some significant advantages in readability for computers, due to the availability of XML parsers. This output is not designed for use in a browser and will cause browsers to crash for large queries. For a complete explanation of the schema, please view the documentation on the QuakeML site.
Search region
There are four possible methods for defining a search region (rectangular, circular, global, Flinn-Engdahl region). Leaving fields blank, will automatically default to a global search. To interactively define a search region, using customised shapes, please use the interactive search page. The defined region is used to check only the prime hypocentre - secondary hypocentres within a search region will not influence the results.
Time period
This is the start and end date to search for events. Only the prime (IASPEI) hypocentre will be searched to match events.
Unknown depths
As some events have no determined depth, you may optionally choose to include events with unknown depths in the search. This will return events which match any selected depth constraint you enter as well as events with no depth.
Unknown magnitudes
As some events have no determined magnitude, you may optionally choose to include events with unknown magnitude values in the search. This will return events which match any selected magnitude constraint you enter as well as events with no magnitude value.
Magnitude type
Limit events by magnitude for specific magnitude types. Due to the large number of magnitude types and the various notation used, the selected type will search all magnitudes of that type. E.g. MB will match all body-wave magnitudes: mb, mB, MB, mb1mx, etc.
Defining phases
Defining phases are travel-times, which have been used in the computation of a hypocentre. You may optionally choose to include events where the number of defining phases for the prime hypocentre is unknown. This only applies if you have specified a minimum or maximum number of defining phases.
Only output Prime hypocentres
The Bulletin output for the IASPEI Reference Events provides the ISC solution as a secondary hypocentre for a particular event. You may optionally limit the output to only show the prime (IASPEI) hypocentres.
Output phases
This includes phase data in the output. Phase data includes any arrival-times, amplitudes, station magnitudes, flags for defining phases and travel-time residuals. The size of the output will be significantly increased by outputting phases.
Output magnitudes
This includes network magnitude data in the output.
Output weblinks
This includes any available links for the event such as a link to the full Bulletin output, a link to form a waveform request and links to the ISC Bulletin for a particular event. There are also links for each author to provide full details of the agency.
Output headers
This includes a header information in the output.
Output comments
This outputs all comments for the ISF output.
