Personal fitness tracker data feeds collective shake maps
The Jawbone fitness tracker company posted motion data from its users in California on August 24, 2014 to create a shake map of the 6.0 earthquake that night. The map matched that from sensors of the US Geological Survey's Shake Maps.
Fitness trackers are an example ofSapiens plurum's developing distributed sensing mechanisms. People form a sensing network around Earth. (image below is an example of a shake map of a 2010 earthquake from the California Integrated Seismic Network )
