Purpose
Abstract During the cruise SO195 researched the Tonga subduction zone at its intersection with the subducting Louisville hotspot track. The project TOTAL is an approach to understand the physical nature of a seismic gap and hence potential seismogenic asperities that may cause a major future megathrust earthquake. The EM120 was used continuously during cruise SO195. No further acquisition information have been provided by the responsible party.
