While some landslides rapidly disintegrate others may stay as coherent blocks. Recently, it has been proposed that submarine landslides could also be characterized by very slow (creeping) deformation. The Tuaheni landslide complex off the east coast of New Zealand may acts as key site for investigating such slow-slipping landslides.
During research cruise TAN1404 (13.04.-08.05.2014) with the New Zealand research vessel Tangaroa, scientist from the Kiel University and the GEOMAR Helmholtz Centre for Ocean Research Kiel collected a 3D-seismic dataset covering parts of the slide complex by means of the so-called P-cable.
The results collected by Felix Gross as part of the project funded by the German Research Foundation (DFG) are the basis for scientists to better assess the dynamics of submarine landslides and their hazard potential. The work is the basis for follow-up work, which looks at the dynamics of submarine landslides in the context of national and international research.
