Towards Automated Real-Time Detection and Location of Large-Scale Landslides through Seismic Waveform Back Projection

Figure 2

The three-component, east, north, vertical (Z), seismic recordings of a landslide event at the station ELD, where broadband (left) and short-period (right) instruments are colocated. (a, b) Raw waveform data and (c, d) bandpass-filtered (1~3 Hz) broadband and short-period waveforms. (e, f) The envelopes of bandpass-filtered broadband and short-period three-component root-mean-square waveforms (section 3.1).

(a) ELD broadband: raw

(b) ELD short-period: raw

(c) ELD broadband: 1~3 Hz

(d) ELD short-period: 1~3 Hz

(e) ELD broadband: envelope

(f) ELD short-period: envelope
