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. |
