Figure 4
Comparison between the recorded (left panels) and the modeled (right panels) waveforms at seismic stations for July (top panels) and August (bottom panels) eruptions. Only stations with clear signals (SNR > 10 dB) are displayed (50 and 38 stations for the July and August eruptions, respectively). Station names, distances and azimuths are specified to the left. Waveforms are time-shifted using a constant celerity of 300 m/s. Vertical red bars are onset times of dominant arrival at each station used for the localization (Figs. 4 and 5), performed on the recorded waveforms band-pass filtered between 0.5 and 2 Hz. To ease the comparison between data and simulation, picks are reported on the modeled waveforms (right). A good agreement beween the predicted and observed arrival times, but also shapes and durations is observed.
