It looks bad!
"Parts of Lau can be seen under the orange shades which corresponds to wave heights 2-3m and above."

A first, rough estimate of #tsunami wave heights between #Tonga and #Australia.
This simulation might be an underestimation (1km resolution, unclear source mechanism -volcano collapse/landslide, 2km³)
It can not adequately reflect complex wave patterns near the coasts.
