On July 9, 1958, an earthquake with a magnitude of 8.3 on the Richter scale rocked a small inlet in Alaska called Lituya Bay. It then caused part of a mountain at the back of the bay to collapse, creating a landslide that caused a megatsunami that flew headlong through the bay. The wave was measured to be 524 meters (about 1,742 ft) high, making it the highest wave in recorded history. In comparison, this wave was higher then any skyscraper on Earth. It swept up three boats; killed two people aboard two of the boats, but amazingly the father and son aboard the other boat both survived. They were carried above the forest, and washed back into the bay. The wave stripped hundreds of trees from up the mountains.

What was the height of the tsunami in Alaska?
the tsunami hit alaska lity bay in july 9,1958 and the tsunami was about 1,720 feet tall
Was this last tsunami caused by oil drilling?
No. There is no record of any oil company ever causing a tsunami.
Why are tsunami waves in the open ocean limited in height?
Because width doesn't matter in a tsunami. The width is typically the length of the shore. It would be extremely difficult to classify a tsunami based upon height and width when the width is simply incomparable.
Does a tsunami lose power?
no, a tsunami slows down when approaching the shore. But it gains height and actually stored its power until it reaches land.
Can a tsunami pick up sharks and throw them on land?
Inevitably some plankton and a range of littoral marine species will be washed onto land and carried inland by the force of the tsunami wave. These are frequently found inland in deposits left by tsunamis and in the geological record can be used to characterize these events in the past.
What was the biggest wave that hit or came to America?
In Lituya bay, Alaska, there is a record of a tsunami of about 524m height. And in Mexico, the Chixculub Crater, 65 million years ago, would have created immense tsunami throughout the Americas.
When does the height of a tsunami increase?
The height of a tsunami increases as it gets closer to the shoreline. It sort of "rolls" up the sea floor, pushing itself higher as it does so.

What year did the biggest tsunami occur?

What happened to the wave height of a Tsunami as it approaches a Shoreline?
it gets higher

Why doesn't a tsunami wave break?
Tsunami waves have a much longer wavelength in proportion to their height than ordinary waves do. They are often miles long.
