Searching the IASPEI Ground Truth (GT) reference events
https://doi.org/10.31905/A1CMX9W7To search the IASPEI reference events, there is a standard 'Bulletin search' page. Additional search pages provide access to specific datasets within the reference events bulletin (e.g. an event catalogue or phase data).
|
Each search page has the option to define a search region using a Google Maps interface on an interactive page. |
Bulletin search
The Bulletin search may be used to output a bulletin of event data in IASPEI Seismic Format or QuakeML. These data include:- hypocentres - both the prime (preferred) origin and secondary estimates;
- magnitudes;
- phase/arrival data;
Event catalogue
Outputs a catalogue of events only showing the prime (IASPEI) hypocentre for each event. The output can either be a CSV file (one line per event) or a QuakeML stream:- only the prime (IASPEI GT) hypocentre for an event is output;
- magnitudes are also output where available.
Arrivals
Searches the IASPEI reference events for arrival (phase) data by station(s) and events. The search outputs the arrivals as either a CSV file (one arrival per line), in IMS1.0 'associated:arrivals' format, or QuakeML. Searches may limit data to only include arrivals with:- specific phase names (e.g. P, PKPdf, S etc.)
- arrival-times (N.b. amplitude data do not always have arrival-times)
- travel-time residuals (from ak135)
- time-defining phases - phases used in the computation of the prime hypocentre
- amplitudes
