Data and Products
The CSN sensor pool produces vast amounts of raw data: each sensor samples acceleration in three axes—vertical, north/south, east/west—50 times per second, in units of about 1/4,000th of the acceleration force of gravity, totaling about 4MB/hour per hour. One thousand sensors collect 100GB/day of raw data. Many CSN sensors send a continuous data stream to cloud servers which perform various types of processing in real time, such as earthquake event detection, calculation of earthquake epicenters, and generation of peak acceleration intensity maps. CSN is also exploring how buildings respond to an earthquake, using novel real time and offline processing tools. More information and data products can be found by following the links below.
