Source Spectra, Moment, and Energy for Recent Eastern Mediterranean Earthquakes: Calibration of International Monitoring System Stations

摘要

In the past several years there have been several large (M(sub w) > 7.0) earthquakes in the eastern Mediterranean region (Gulf of Aqaba, Racha, Adana, etc.), many of which have had aftershock deployments by local seismological organizations. In addition to providing ground truth data (GT << 5 km) that is used in regional location calibration and validation, the waveform data can be used to aid in calibrating regional magnitudes, seismic discriminants, and velocity structure. For small regional events (m(sub b) << 4.5), a stable, accurate magnitude is essential in the development of realistic detection threshold curves, proper magnitude and distance amplitude correction processing, formation of an M(sub s):m(sub b) discriminant, and accurate yield determination of clandestine nuclear explosions.
