video: We have a choice when issuing earthquake warnings: 1) issue alerts for weak shaking and potentially provide long warning times, but also send alerts for many events that do not go on to produce strong ground shaking, or 2) issue alerts only when ground shaking is expected to be damaging and risk the alerts being too late. This material relates to a paper that appeared in the 21 March 2018, issue of Science Advances, published by AAAS. The paper, by S.E. Minson at US Geological Survey in Menlo Park, Calif., and colleagues was titled, "The limits of earthquake early warning: Timeliness of ground motion estimates." view more
