Washington is earthquake and tsunami country! Washington’s outer and inner coasts are highly vulnerable to tsunamis thanks to the presence of numerous crustal faults and the Cascadia Subduction Zone (CSZ) offshore.
How far inland would a tsunami go in Seattle?
The new models and maps show how, in some hot spots, a tsunami could cause inundation and dangerous currents in inland areas. The Port of Tacoma may see depths of 3.5 feet. Seattle’s Harbor Island could be inundated up to 4 feet.
When was the last tsunami in Seattle?
The most recent was in 1949 when the Tacoma Narrows experienced a landslide that triggered 6 to 8 foot tsunami following that year’s magnitude 7.1 earthquake. The 900 AD Seattle Fault earthquake triggered massive landslides into Lake Washington, but no evidence has been found yet that they caused tsunamis.
Is Washington under tsunami warning?
The tsunami advisory for the Washington and Oregon coasts is cancelled. No tsunami danger exists for the area. To repeat, the tsunami advisory is cancelled.
Do tsunamis happen in Seattle?
The most likely effect of a tsunami from the Pacific in Seattle would be strong currents. Tsunamis can be generated within Puget Sound by landslides or earthquakes. The most frequent cause of Puget Sound tsunamis is landslides.
Is Seattle in danger of an earthquake?
Earthquakes are the most serious hazard facing Seattle. Unlike other potentially catastrophic hazards, Seattle has had and will experience powerful earthquakes.
When was the last time a tsunami hit Washington State?
The most recent significant tsunami to reach the Washington coast happened in 1964. However, historically, tsunamis have caused great damage.
Can Puget Sound have a tsunami?
– A 9.0 magnitude subduction earthquake off the Washington coast would generate a tsunami capable of submerging not only coastal areas but also most of the Puget Sound shoreline with churning waves of seawater several feet high for up to 14 hours, says a newly released study.
Will a tsunami hit Washington?
In the meantime, Washington is still vulnerable to tsunamis resulting from earthquakes or undersea volcanic eruptions thousands of miles away. The most damaging could come from Alaska, but just last weekend the tsunami generated by the explosion of an underwater volcano in Tonga sent waves around the Pacific.
Has Seattle ever had a tsunami?
An earthquake on the Seattle Fault about 1,000 years ago produced a 16ft tsunami. The Seattle Fault, which runs through Seattle’s midsection and through Puget Sound to Bainbridge Island, caused a tsunami around 900 AD. If a tsunami like the one in 900 AD happened again it would be devastating.

Can a tsunami hit Everett WA?

Is Seattle in a tsunami zone?
The Seattle Fault is known to have had an earthquake event that directly produced a tsunami (see Atwater and others, 1992), and other crustal faults (Tacoma Fault and Darrington-Devils Mountain fault zone, for example) could produce tsunamis (Williams and others, 2000).
Is Seattle safe from tsunami?
Tsunami waves could reach Seattle in 2 hours and 20 minutes after an earthquake. Allen told Q13FOX that’s exactly why it’s not safe to leave your safe place after the first wave.
Can Seattle be hit by a tsunami?
Tsunamis generated in the Pacific Ocean off Washington’s coast will not have as great of an effect in Seattle as they will on the Pacific Coast, but low-lying areas may experience flooding, and strong currents will likely be present in Puget Sound for hours after the earthquake.
What is the largest earthquake in Seattle?
– The Seattle Fault Zone extends east-west through the middle of the city. – A Seattle Fault quake could be as large as M7.5,160 but less than M7.0 is more probable. – The most recent Seattle Fault earthquake was about 1,100 years ago; – The Seattle Fault has been active about three or four times in the past 3,000 years.
