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

Figure 3

The raw recordings (upper row), 1~3 Hz bandpass-filtered waveforms (middle row), and time-frequency spectrum (bottom row) of a landslide (a), a typical local earthquake (b), and a typical teleseismic event (c). The color scale in the bottom row indicates the normalized amplitudes of the raw recordings.
