Looming Giant Landslide in Alaska Could Trigger Enormous Tsunami at Any Moment

The collapse of an unstable mountain slope in Alaska could trigger a catastrophic tsunami in Harriman Fjord, scientists warn.

Rolling through Prince William Sound, which is located some 60 miles (100 kilometers) from Anchorage, this massive wall of water would threaten potentially hundreds of people at one time.

Frighteningly, this pending landslide could spawn an enormous tsunami in Harriman Fjord, which is located some 60 miles (100 kilometers) from Anchorage.

Earthquakes could possibly accelerate the rate of downslope movement of material in this case, but without knowing the rock type(s) involved, it would be difficult to assess the risk of complete and catastrophic failure.
IF the slope failed, simultaneously and completely, yes, water would be displaced and a displacement wave generated which could reach significant heights in the estuaries, threatening anyone living there and any vessels on the waterways.

But, since the situation has already been monitored for over 60 years, how soon that failure may occur, or whether the failure would continue as slow moving mass wasting remains to be seen. Considering the relative proximity to the 1964 earthquake epicenter, it is difficult to say with certainty that an earthquake would necessarily trigger a slope failure.
