Broadband Ground Velocity (GRNDVEL)

Broadband Ground Velocity is the time-series seismic signal sensed by a Broadband Ocean Bottom Seismometer. These seismic signals provide a characterization of seismicity/earthquake activity along tectonic plate boundaries where two key phenomena can occur: large-magnitude subduction zone earthquakes and seismicity associated with migration of melt (magma) beneath the seafloor at underwater volcanoes.
