The U.S. Geological Survey’s NetQuakes project is rolling out a new network of seismograph sensors that will form a denser network of readings to better measure ground motion during earthquakes. The new type of digital seismograph connects to a local network via WiFi and transmits its data direct to the USGS after an earthquake of magnitude 3 or higher. The devices are designed to be installed in private homes, businesses and public buildings, tapping into existing networks and not requiring significant bandwidth.
This passive citizen science network is rolling out in Northern California, Southern California and the Pacific Northwest. The team is looking specifically for locations near existing faults and near significant business districts. The sensors require very little maintenance.
