METHOD AND SYSTEM FOR OBTAINING EARTHQUAKE PARAMETER ESTIMATES, AND EARTHQUAKE SEARCH ENGINE

摘要

Disclosed are methods and systems of rapidly determining earthquake parameters of an earthquake and related search engines. The method comprises inputting a seismogram of the earthquake, searching concurrently in pre-established historical seismogram database and theoretical seismogram database by use of an approximate nearest neighbor search method, to find a set of seismograms similar to the input seismogram according to a preset similarity condition, and determining from the set of similar seismograms one or more seismograms matched with the input seismogram, and determining the earthquake parameters from the matched seismograms. With the present invention, it is possible to search in millions of seismograms and determine parameters for an earthquake in a few second, and thus realize rapid and even real-time estimation of earthquake parameters.
