DATA
Earthquake LOD and datasets
Discover hypocenters, stations, observed waves, and strong-motion records from multiple networks through a common RDF model.
CITIZEN SEISMOLOGY NETWORK
Explore citizen-seismology observations, Earthquake LOD integrating public records from JMA, FDSN, and J-SHIS, and the shared ontology that connects them.

VOCABULARY
Access the shared vocabulary, WIDOCO specification, and Turtle source describing the meaning and relationships of the data.
OBSERVATION
Browse Citizen Seismology Network station information and previously collected observations.
Archive available: Real-time aggregation from Raspberry Pi seismometers is currently unavailable. Archived observations, station information, datasets, and LOD services remain accessible.
Citizen Seismology Network (CSN), initiated with Professor Kim at Yokohama City University, supports seismology research, education, and citizen science through compact instruments and open data.
Earthquake LOD received the Oracle Japan Award and Open Science Award at LOD Challenge 2022.
