摘要
We present a new method for location of the source of volcanic harmonic tremor, that employs the Fourier phases of an observed tremor segment recorded at various seismic stations, a condition on the inferred phase at the source, and a search location scheme. We discuss the assumptions and limitations inherent to the proposed method. As an illustration of application to real data, the method is used to locate twenty sources of harmonic tremor occurred at Popocate' petl volcano (Mexico) during the July 2006 tremor episode; the located sources agree quite well with results from other studies of seismicity in this volcano.
