Looking back: Three years since triple tsunamis, how frontier science supported NZers return home safely sooner

Three years ago today, 5 March 2021, New Zealand experienced an extraordinary day of three large offshore earthquakes – each one triggering a tsunami threat to coastal dwellers in the North Island.

From the first quake, our geohazard monitoring centre was analysing and tracking the tsunami waves.

Visit GeoNet News to read about the frontier science that was rapidly working away to calculate how the waves would progress around the coast through time for these overlapping events and for the first time forecast when the waves would subside and people could safely return home.
