Massive Alaska megatsunami was second largest ever recorded
A nearly 500-meter-tall megatsunami— the second largest ever recorded—struck Alaska's Tracy Arm Fjord last summer, triggered by a 64-million-cubic-meter rock slide linked to climate-driven glacier melt. Scientists warn such events are becoming far more frequent, and cruise companies have suspended visits to the fjord after the early morning incident narrowly avoided casualties involving tourist ships.
