Accept/parse QuakeML from GEOFON to produce input for a new run
When a new event occurs, we can query the GEOFON fdsnws-event web service to get event parameters, including focal mechanism if available.
Angelo:
Peter to work with Riccardo in preparing the input which will be as simple as possible for the moment (yaml/json) including EQ Lat/Lon/Depth/Magnitude, and as soon as available the focal mechanism
This merge request does the query, parses the XML, and produces a basic Python structure. This can be easily serialised in the flavour of your choice.
For example, here is the YAML output for a large event in Greece: gfz2021eksc:
date: '2021-03-04'
focalmechanism:
- dip: 48.75643809
rake: -91.74289876

- dip: 41.27378495

strike: 329.2004058

time: 18:38:20.19439ZThere are two (dip, rake, strike) sections for the two nodal planes. The QuakeML doesn't help us decide which to use.
From here, some integration will be needed to use the YAML to drive a run of the shake map.
