From: Discriminating non-seismic long-period pulses and noise to improve earthquake source inversion
SWIFT inversion results affected by non-seismic pulses. a Map showing source locations and focal mechanisms of automatic and manual CMT solutions for an earthquake at 11:44 (UTC) on February 25, 2014. b Waveform fits between synthetic and observed displacement seismograms based on the automatic CMT solution. The three-component seismograms recorded at station LUBP were contaminated by non-seismic pulses. Note that the amplitude scales for these seismograms (2 × 10−2 m) are different from those for the other stations (2 × 10−4 m). c Waveform fits between synthetic and observed displacement seismograms based on the manual CMT solution in which the seismograms containing non-seismic pulses recorded at LUBP were discarded
