CITIZEN SEISMOLOGY NETWORK

Opening seismic observations for research and education

Explore citizen-seismology observations, Earthquake LOD integrating public records from JMA, FDSN, and J-SHIS, and the shared ontology that connects them.

Research resources

DATA

Earthquake LOD and datasets

Discover hypocenters, stations, observed waves, and strong-motion records from multiple networks through a common RDF model.

VOCABULARY

Earthquake Ontology

Access the shared vocabulary, WIDOCO specification, and Turtle source describing the meaning and relationships of the data.

OBSERVATION

Stations and CSN archive

Browse Citizen Seismology Network station information and previously collected observations.

Service status

Archive available: Real-time aggregation from Raspberry Pi seismometers is currently unavailable. Archived observations, station information, datasets, and LOD services remain accessible.

About the project

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.
