Can a tsunami travel over 1000 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.
Has there ever been a 100 foot tsunami?
An earthquake followed by a landslide in 1958 in Alaska’s Lituya Bay generated a wave 100 feet high, the tallest tsunami ever documented. When the wave ran ashore, it snapped trees 1,700 feet upslope. Five deaths were recorded, but property damage was minimal because there were few cities or towns nearby.
Can a tsunami go 500 mph?
In the deep ocean, tsunamis can move as fast as a jet plane, over 500 mph (800 km/h), and can cross entire oceans in less than a day. The distance between waves is the wavelength.
What is the biggest tsunami to ever hit land?
Lituya Bay, Alaska, July 9, 1958 Its over 1,700-foot wave was the largest ever recorded for a tsunami. It inundated five square miles of land and cleared hundreds of thousands of trees. Remarkably, only two fatalities occurred.
How far inland would 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.

A tsunami that reaches a height of 300 feet when it rears up at the shore, will lose energy as it travels inland. It’s all about energy. Frequency (depending on the source of the tsunami) and Amplitude (shape of ocean floor, shoreline and up-slope factors).
Why are there so many tsunamis in Europe?
Causes Most of the tsunamis that have occurred within Europe have happened in the Mediterranean Sea because in the Mediterranean Sea there are earthquakes, submarine landslide and volcanoes.
