A massive landslide in Alaska triggered the second-highest tsunami ever recorded, sending water and debris 1,580 feet up a mountainside. The disaster was preceded by several warning signs, including rapid glacier retreat, heavy rainfall, and thousands of tiny seismic tremors. As glaciers retreat, similar disasters could become a growing danger in mountainous coastal regions.
