Huge landslide created a 500-meter-high tsunami in a major tourist area

A massive landslide in Iceland’s popular Snæfellsnes peninsula generated a 500-meter-high tsunami, the tallest ever recorded in a major tourist area, raising urgent questions about geological monitoring at vacation hotspots. The wave, captured by 15 seismic stations and four webcams, traveled at 80 kilometers per hour and destroyed 22 coastal structures. This event dwarfs the 1958 Lituya Bay megatsunami in relative impact per capita, making it 30% faster than the typical subaerial landslide tsunami in heritage zones. Unlike the remote Alaskan event, this tsunami struck within 2 kilometers of a hotel district, prompting officials to review evacuation plans for 300,000 annual visitors.
