Animation Showing Spatial and Temporal Variations of Seismic Velocity on Kyushu Island (VIDEO)
Caption
The time variation of seismic velocity within 30 days time window relative to the averaged pre-earthquake value are displayed. Warm colors indicate regions where seismic velocity was decreased. During the 2016 earthquake, seismic velocity around the seismogenic Hinagu-Futagawa fault system and Mount Aso decreased greatly. Cold colors indicate regions where seismic velocity was increased. Seismic velocity at Mount Aso recovered rapidly and was faster than the pre-earthquake velocity after the eruption. The date described above shows the central date within the 30-day window. Black circles are Hi-net stations.
