Tsunami hazard at Lake Tekapo


This research mapped the Lake Tekapo lake bed and underlying lake sediments to identify past landslides into the lake and delta collapses within the lake, and modelled potential tsunamis from these landslides/delta collapses.

The research found evidence for many landslides in the lake over the past 12,000 years, which likely causes tsunamis in the lake. It concludes that an earthquake that causes significant ground shaking at Lake Tekapo could trigger multiple tsunamis in the lake.


Emergency management relevance

This research contributes to our understanding of seiche and tsunami hazards in the Mackenzie Basin lakes, specifically Lake Tekapo.
