Source process and tectonic implication of the January 20, 2007 Odaesan earthquake, South Korea

The source process for the 20th of January 2007, Mw 4.5 Odaesan earthquake in South Korea is investigated in the low- and high-frequency bands, using velocity and acceleration waveform data recorded by the Korea Meteorological Administration Seismographic Network at distances less than 70 km from the epicenter. Synthetic Green functions are adopted for the low-frequency band of 0.1–0.3 Hz by using the wave-number integration technique and the...
