How far inland would a tsunami go in Seattle?

There is evidence that an earthquake on the Seattle Fault that occurred around 900 AD produced a 16-foot tsunami. The National Oceanic and Atmospheric Administration (NOAA) recreated this tsunami using a model. The modelled tsunami would flood areas up to one mile inland with depths up to 5 meters.

Would a tsunami reach Seattle?

Bellingham, Olympia, Seattle, and Tacoma could see anywhere from 6 inches to 11 feet of water from a tsunami off the Washington coast. EVERETT, Wash. Part of the Snohomish River Delta between Everett and Marysville could get nearly 6 feet, and Seattle’s Harbor Island could be inundated with nearly 4 feet of water.

Is it possible for a tsunami to hit Washington State?

All marine shorelines in Washington State are vulnerable to tsunamis. The Pacific Coast, the Strait of Juan de Fuca, and Puget Sound all have geologic evidence for past tsunamis, and future tsunamis are inevitable.

Will Seattle be underwater?

Climate change is expected to accelerate rising sea levels during the next century. Central estimates indicate that Seattle will experience 10 inches of sea-level rise by 2050, and 28 inches by 2100, and 47 inches by 2150.

Will the Cascadia tsunami reach Seattle?

New tsunami hazard maps published by the Washington Geological Survey and the Washington State Department of Natural Resources (DNR) show that a large earthquake on the Cascadia subduction zone (CSZ) off the Washington coast could cause a tsunami that will not only reach the Puget Sound and Hood Canal, but will leave …

What would a 9.0 earthquake do to Seattle?

– 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.

Would Cascadia tsunami hit Seattle?

How far inland can a tsunami travel?

10 miles
Tsunamis can travel as far as 10 miles (16 km) inland, depending on the shape and slope of the shoreline. Hurricanes also drive the sea miles inward, putting people at risk. But even hurricane veterans may ignore orders to evacuate.

Is Seattle overdue for an earthquake?

According to recent studies, Washington State is 200 years overdue for a 9.7 magnitude earthquake. Experts suggest that this earthquake will occur at the Cascadia subduction zone at some point within the next 50 years. This earthquake is also expected to trigger a 100 foot tall tsunami.

How can seismologists simulate the last Cascadia earthquake?

While there are not seismological recordings of the last Cascadia earthquake, seismologists can simulate ground shaking using information about the fault and observations from other subduction zone earthquakes.

Will the next rupture of the Cascadia subduction zone spell a disaster?

The interface of the two plates is the Cascadia subduction zone, a fault that has generated magnitude-8.0+ earthquakes over intervals spanning many centuries. The Next Rupture of the Cascadia Subduction Zone Will Spell the Worst Natural Disaster in the History of North America An earthquake will destroy a sizable portion of the coastal Northwest.

What are the most dangerous earthquake zones in the Seattle area?

Discover in this article the most dangerous earthquake zones for Seattle and its area: The Cascadia Subduction Zone, the Seattle Fault and the South Whidbey Island Fault. The below map shows that Seattle and its surroundings is constantly …

What was the last major earthquake in the Pacific Northwest?

The region’s last major earthquake was in 1700, when an approximate magnitude-9.0 earthquake ruptured the full length of the fault, which extends from off the coast of Northern California to Vancouver Island in Canada. A repeat of the 1700 earthquake today would cause extensive damage throughout the Pacific Northwest.
