Detailed Description

Figure 7. Top) Screenshot of seismic data filtered between 0.005 and 0.07 Hz produced with Hydra location software (Patton and others, 2016). Duration of window is 20 minutes, the start time of each seismogram is labeled on the bottom left. The color bars represent predicted wave arrival times for an earthquake at 0 km depth using AK135 model (pink for P phases, green for S phases, purple for surface waves). OT marks the origin time. The emergent character of the signal makes it impossible to pick first arrivals accurately and thus impossible to locate using traditional seismic processing.
