英文摘要Earthquake source characterization has been significantly speeded up in the last decade with the development of rapid inversion techniques in seismology. Among these techniques, the W-phase source inversion method quickly provides point source parameters of large earthquakes using very long period seismic waves recorded at teleseismic distances. Although the W-phase method was initially developed to work at global scale (within 20 to 30min after the origin time), faster results can be obtained when seismological data are available at regional distances (i.e., 12 degrees). In this study, we assess the use and reliability of regional W-phase source estimates in China and neighboring areas. Our implementation uses broadband records from the Chinese network supplemented by global seismological stations installed in the region. Using this data set and minor modifications to the W-phase algorithm, we show that reliable solutions can be retrieved automatically within 4 to 7min after the earthquake origin time. Moreover, the method yields stable results down to M-w=5.0 events, which is well below the size of earthquakes that are rapidly characterized using W-phase inversions at teleseismic distances.
