- Seismologists and earthquake researchers
- Worth noticing
- It warns that a focal mechanism cannot distinguish the fault plane from its auxiliary plane; both candidates should be checked.
Field notes
The workflow accepts either a ComCat event or manually entered hypocentre and mechanism values, then projects both nodal-plane candidates against terrain. Users can adjust location and orientation uncertainty and choose between a full uncertainty envelope and Cronin’s seven bounding planes. The page describes outputs including a publication-style report, GeoJSON, KML, and screenshots, and says locally supplied terrain files stay on the user's computer.
