Waves of this type are called Mega Tsunami. They are so great that they can reach several hundred meters in height, travel at the speed of a jet aircraft and get up to 12 miles (20 Kilometers) inland.

How far inland can a tsunami travel in Florida?
Tsunamis can travel as far as 10 miles (16 km) inland, depending on the shape and slope of the shoreline.
How far inland can a 100 ft tsunami go?
Most tsunamis are less than 10 feet high when they hit land, but they can reach more than 100 feet high. When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger. However, tsunamis can surge up to 10 miles inland.
How far inland would a 1000 foot tsunami travel?
Tsunami waves can continously flood or inundate low lying coastal areas for hours. Flooding can extend inland by 300 meters (~1000 feet) or more, covering large expanses of land with water and debris.
How far inland would a 200 foot tsunami travel?
However, while there is no indication it could happen soon (but could), there are scientifically sound reasons for concern that at some point a mega-tsunami could engulf the entire East Coast with a wave almost 200 feet high sweeping everything and everybody up to 20 miles inland.
How far inland can a mega tsunami reach?
Waves of this type are called Mega Tsunami. They are so great that they can reach several hundred meters in height, travel at the speed of a jet aircraft and get up to 12 miles (20 Kilometers) inland.
How far inland can tsunami go?
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.
How far inland did the 2004 tsunami go?
In many places, the waves reached as far as 2 km (1.2 mi) inland. Because the 1,600 km (1,000 mi) fault affected by the earthquake was in a nearly north–south orientation, the greatest strength of the tsunami waves was in an east–west direction.
What is the farthest a tsunami has Travelled?
Tsunami waves can be very long (as much as 60 miles, or 100 kilometers) and be as far as one hour apart.The Indian Ocean tsunami traveled as much as 3,000 miles (nearly 5,000 kilometers) to Africa, arriving with sufficient force to kill people and destroy property.
How far inland will the Cascadia earthquake reach?
The shaking will be felt for hundreds of miles – from the coast all the way inland to Boise, Idaho, even to the southeast toward Sacramento in California. As one section of the sea floor drops, so will the ocean water above it creating a massive tsunami that will inundate low-lying coastal communities.
How big is a mega tsunami?
States that “mega-tsunamis are defined in the literature as waves that are more than 300 ft (100 m) high, indeed, some tsunami researchers even consider mega-tsunamis to be waves more than a thousand feet (> 300 m) high.”
Can you surf a tsunami?
You can’t surf a tsunami because it doesn’t have a face.On the contrary, a tsunami wave approaching land is more like a wall of whitewater. It doesn’t stack up cleanly into a breaking wave; only a portion of the wave is able to stack up tall.
How big were the waves in the 2004 tsunami?
2004 Indian Ocean earthquake and tsunami timeline
+20 to 30 minutes: Tsunami waves more than 100 feet high pound the Banda Aceh coast, killing about 170,000 people and destroying buildings and infrastructure.
How high do you have to be to be safe from a tsunami?
100 feet
Use t hem to guide you to a safe area. If no maps or signs are available, go to an area 100 feet above sea level or two miles inland, away from the coast. If you cannot get this far, go as high as possible. Every foot inland or upwards can make a difference.

What would happen if the Cascadia subduction zone rupture?
A Tsunami is Born
When the Cascadia subduction zone ruptures, it causes part of the seafloor to move abruptly upwards. This displaces the column of water above the rupture, and the result is a tsunami: a series of waves that travel outwards in all directions from the place where the uplift occurred.
On what plate does the states of the Pacific Northwest sit atop?
Cascadia and the ‘Really Big One’
The Cascadia subduction zone is a region where two tectonic plates are colliding. The Juan de Fuca, a small oceanic plate, is being driven under the North American plate, atop which the continental U.S. sits.
Is it safe to be in the ocean during a tsunami?
Since tsunami waves cannot be seen in the open ocean, do not return to port if you are at sea and a tsunami warning has been issued. Port facilities may become damaged and hazardous with debris.Boats are safer from tsunami damage while in the deep ocean ( > 100 m) rather than moored in a harbor.
