International Seismological Datacenter. An Algorithm for Associating Reported Arrivals to a Global Seismic Network into Groups Defining Seismic Events

摘要

The term event entry is introduced for any combination of three kinematical observations (arrival times, slownesses or azimuths) and the completeness of the algorithm is assured by the testing of all event entries. However, restrictions in the complete search are needed to avoid unacceptable computer times. These restrictions are based on the principle that the observations defining a new event must all have full evidential value. This means that the defining observations of the new event are not allowed to be predicted by another event. The decision rules used are based on statistical confidence intervals.
