To better understand subsurface processes associated with earthquakes and eruptions of Mount Aso, researchers investigated a very long period (VLP) seismicity dataset collected over two years. A new technique was developed to locate VLP events, and two clusters of such events were detected. Changes in the locations of VLP events were closely associated with earthquake and eruption occurrences. This method advances understanding of seismic and volcanic processes and could contribute to disaster mitigation.
