Earthquake Ontology

Earthquake Ontology

This ontology provides common classes and properties for hypocenters, observation stations, observed waves, and strong-motion records published by JMA, FDSN, K-NET/KiK-net, and other seismic observation networks.

• Ontology specification generated by WIDOCO
• Turtle serialization
• Source repository

Policy

The external providers remain authoritative for the original records. This LOD is an RDF representation for discovery and linking. A snapshot is created for each acquisition, and stable source URIs are retained when available.
