Project Title: Finding tsunami-causing landslide deposits in the lakes of New ZealandRyan

Cohort: 2016/17





I studied Geography at the University of Dundee and following this, I completed an MSc in Water Hazards, Risk and Resilience at the University of Dundee in 2015. For my MSc thesis, I investigated the potential of coastal landslides in Shetland as causal mechanisms for the mid- and late-Holocene tsunamis in Shetland which have been previously identified in the stratigraphy at various locations around the Shetland Isles. My main research interests are natural hazards and geomorphology.

My PhD project aims on identifying landslide deposits in lakes in New Zealand and determine if these landslides generated tsunamis upon impact. The risk of landslide-tsunami hazard is not well known in New Zealand as currently, there is only a partial inventory of terrestrial deposits and limited investigation of submarine deposits in the lakes and fiords. Additionally, so few have been recorded/observed but there is growing concern that a rupture along the Alpine Fault will cause large numbers of landslides across New Zealand, and many may fall into lakes and generate tsunamis. These pose large risks to many waterside developments along lake shores in this rapidly developing tourist region.

The methodology will encompass a suite of marine geophysical equipment including a boat-mounted multibeam echosounder survey system to create a high resolution bathymetric map of the lake bed to identify landslide deposits. A sub-bottom profiler system will also be used to identify landslide deposits which may be buried by lacustrine sediments.
