The QuakeFinder Network
is the world’s largest installation of sensors that detect the electromagnetic effects preceding major earthquakes, and is the key to developing a reliable earthquake forecasting system.

Expansion
QuakeFinder’s research goals will be reached faster with more data. More data requires more sensors. The company is actively expanding the network to provide better coverage of the California faults and to cover more active faults around the “Ring of Fire”.

Locations
The QuakeFinder network currently includes more than 60+ sensors in California, 2 in Peru and 2 in Taiwan. Additional sensor locations are being sought; individuals, companies, and organizations located in these regions are encouraged to consider hosting a station; see the Hosting page.

Sensors
Each sensor in the QuakeFinder Network includes instrumentation to detect 3 axes of magnetic field disturbances, 2 types of ions in the air, a geophone to detect mechanical disturbances, temperature and relative humidity sensors, and associated data acquisition and transmission equipment. The sensors collect and store the data locally, and then transmit the raw data to the QF Data Center in Palo Alto, Ca.
