Heller, V. (2020). THE NEED FOR A PARADIGM SHIFT IN SUBAERIAL LANDSLIDE-TSUNAMI RESEARCH. Coastal Engineering Proceedings, (36v), currents.36.


Subaerial landslide-tsunamis (SLTs) are caused by mass movements such as landslides, rock falls or glacier calving. Research into SLTs is ongoing for many decades, however, the advancement in the physical understanding and reliability of hazard assessment methods is not reflecting the number of articles published per year. It appears that a paradigm shift in SLT research is required for a genuine advancement. This article critically reviews the state-of-the-art of SLT research, highlights current limitations and introduces potential candidates to perform this needed paradigm shift.
