Seismogram “Picking Error” Experiment

Abstract

The Seismogram Picking Error From Analyst Review (SPEAR) project is looking for input from analysts with experience in picking earthquake or other seismic data. The project, begun in February 2008 as a grassroots effort among the authors' institutions, will aid the seismological community in producing more reliable results for hypocenter locations and in establishing Earth models that are more accurate. The project could develop into a continuous forum for the seismological community to better understand the errors, biases, and mental processes or steps involved in picking seismic data, and to establish standards for how to pick and assess seismic data.
