Citizen Seismology: How to Involve the Public in Earthquake Response

Introduction Documentation of the effects of earthquakes has always been, and remains, essential in seismology. Understanding tectonic setting and seismic hazard studies requires knowledge of seismicity over long periods of time, well before the instrumental era. ese effects can be reported in historical documents, recorded on historicalContents Introduction ...237 e EMSC: Roles and Web Site ...238 Tools that Collate Earthquake Information from the Public ...239 Lessons Learned ... 244Lessons Learned from Felt Map ...245 Lessons Learned from Online Macroseismic Questionnaires ...254 Lessons Learned from Collection of Photographs and Videos ...256Discussion and Future Evolution ...257 Concluding Remarks ...258 Acknowledgment ...258 References ...259monuments, or observed in the landscape. For more recent earthquakes, field surveys are performed to better understand the distribution and nature of the damage, to calibrate historical observations, and ultimately to improve risk assessment and enhance our capacity to predict damage scenarios in future earthquakes.
