Massive ash deposits blocked the Kaiwaka Stream, which had previously drained Lake Rotomahana into Lake Tarawera. As the craters gradually refilled with water, the blockage caused Rotomahana to expand dramatically - rising 35 metre...

The 1886 eruption was the largest in New Zealand in the past 500 years and was classified as a VEI-5 event - powerful enough to reshape a region but contained enough to spare the wider country. Its legacy shaped how New Zealand understood its volcanic risks. The eruption drove ho...
