FILE - Mount Susitna, which is also known as Sleeping Lady, is shown Friday, April 16, 2021, on the other side of Cook Inlet from downtown Anchorage, Alaska. Researchers have concluded there is a "rare but real risk" that an earthquake-produced tsunami could inundate parts of coastal Anchorage under certain conditions, a newspaper reported, a shift from the prior understanding of the risk posed to Alaska's largest city.
