A web application for the three dimensional visualisation of earthquake hypocentres and their focal mechanisms based on the FDSN API.
The 3D earthquake explorer shows earthquakes and their focal mechanisms on a globe.
It can be deployed as a static set and does not require a backend.
The earthquakes are loaded from an FDSN Web Service endpoint directly in the browser.
It is currently accessible via the GFZ Earthquake Explorer, but endpoints can be manually specified with the url parameter.
Open the GFZ Earthquake Explorer (https://geofon.gfz-potsdam.de/eqexplorer/). Apply filters as required. Afterwards, click on the 3D button, as highlighted in the screenshot:
A new window with the 3D Earthquake Explorer will open.
If you want to include the viewer into your own application, either as direct link to the GFZ service or your own static page, add the FDSN API call as url parameter to the domain. Note that the url parameter must be encoded.

The FDSN endpoint must support the parameter includefocalmechanisms=true and deliver the principalAxes and nodalPlanes attributes (see QuakeML2.0 documentation) for the individaual events.
Run npm install followed by npm run dev. This starts a development server at http://localhost:8080 .
In case you have problems with the current node version, you can also
use the docker setup:
docker compose -f docker-compose-dev.yml build
docker compose -f docker-compose-dev.yml up -d
The app should be visible the same way on http://localhost:8080.
There are a few test that can be run with npm run test.
