Increasing Mega-Tsunami Danger for Four States in the US, Experts Alert

Buzzline

Recent geological research indicates that Alaska, Hawaii, Washington, and Oregon face an escalating threat from a mega-tsunami caused by the Cascadia Subduction Zone. Experts warn that a potential rupture could generate waves reaching up to 1,000 feet, impacting US shorelines with merely a 15-minute alert. The last significant full-margin earthquake occurred in 1700, and government officials predict a 1-in-3 likelihood of a rupture occurring within the next 50 years. Here’s what every household along the coast should be aware of right now.

00:00A new analysis is putting four U.S. states

00:02directly in the line of a potential mega-tsunami.

00:05And scientists say the risk is rising.

00:08Researchers studying the Cascadia subduction zone

00:11now believe a future rupture could send 1,000-foot waves

00:15crashing toward Alaska, Hawaii, Washington, and Oregon.

00:19The geological pressure has been building for over 320 years.

00:23The last full-margin quake hit in 1700.

00:26Geologists warn coastal communities

00:28have just 15 minutes between the shaking and the wall of water.

00:32Seattle, Portland, and parts of the Hawaiian Islands

00:36could see waves taller than the Space Needle.

00:42for the first time in over a decade.

00:44Millions of Americans live within the inundation zone,

00:47and most have no idea.

00:49Federal officials say the probability of a Cascadia rupture

00:52in the next 50 years is roughly one in three.

00:55When it hits, there will be no second chance to learn the route.
