About:
This website displays near-real-time, machine-learning based, double-difference
hypocenter locations for earthquakes recorded by the Ocean Observatories Initiative (OOI) cabled OBS array at Axial Seamount. The continuous waveform data is processed using machine-learning methods for detection, phase arrival-time picking, and association. New events are then located relative to a high-resolution background (base) catalog using waveform cross-correlation and double-differences. For more details see here.
Precursory mixed frequency earthquakes (MFEs; blue squares in figure), lava flow events, and whale calls are also monitored, using unsupervised ML.
This web site is updated every 10 minutes.
