Milford Sound faces significant tsunami risk from landslides

Research shows that Milford Sound faces a landslide tsunami risk that could create waves up to 17 meters high. This risk is estimated to be about 50 times greater than the danger posed by the 2019 Whakaari eruption. The 2019 Whakaari disaster resulted in 22 deaths and led to a halt in tourism due to safety concerns. In contrast, the potential for a similar or worse disaster at Milford Sound raises questions about future tourism in the area. Mitigating the tsunami risk may require closing Milford Sound to mass tourism, a decision that could be controversial. The situation highlights the ongoing challenges of balancing safety and tourism in New Zealand's popular destinations.
