On February 23, 2017, the U.S. Geological Survey announced that it will release updated maps detailing the potential of natural and induced seismic events on March 1, 2017. The 2017 maps mark the second year that USGS has projected both natural and induced seismic risks. USGS previously stated that the best indicator of future induced seismic events in a given region is the number of induced seismic events that the region experienced in the previous 12 months. Therefore, the 2017 induced hazard map is likely to reflect recent seismic activities that USGS believes were induced by human activities such as wastewater injection, coal mining, and reservoir drawdowns.
