When tsunamis form in the open ocean they can reach speeds of 500 miles per hour, but they are very small: usually less than three feet high. When they hit shallow water as they approach a shoreline, they slow down, sometimes to less than 50 miles per hour, but build dramatically in weight because of how heavy the water is.

2nd Answereer says: In the deep open sea, tsunamis move at speeds approaching a jet aircraft (500 mph or more). As they approach the shore, they slow down. When a tsunami arrives at the shore, it usually does so as a rapidly rising tide moving at about 70 km/hour (45 mph).

Where do tsunamis mostly occur in the world?

Tsunamis mostly occur in the Pacific Ocean's "Ring of Fire," where tectonic plate movements are frequent. Countries such as Japan, Indonesia, and Chile are particularly prone to tsunamis due to their proximity to tectonic plate boundaries and underwater earthquakes.


How fast does the Pacific Ocean travel?

I belive you are talking about how much does the ocean get impacted by the gravity of the moon. Depending on the distance of the moon from earth so thats why you get tide in and tide out.


How do fast tsunamis travel in deep water?

Fast tsunamis travel in deep water because they have long wavelengths and low amplitudes, allowing them to move quickly with minimal energy loss. The speed of a tsunami is determined by the depth of the water it is traveling through, with deeper water supporting faster wave propagation. Tsunamis are not affected by surface friction in deep water, which also contributes to their fast travel speed.


How fast are tsunamis in miles per hour?

Tsunamis can travel close to the speed of sound. The most recent one traveled at about 200 mph.


Why do tsunamis go so fast?

Tsunamis can travel at high speeds, often over 500 mph, because they are generated by large underwater earthquakes or volcanic eruptions that displace a massive amount of water rapidly. This rapid displacement creates long waves that travel across the ocean at high speeds with very long wavelengths.


How fast do most tsunamis travel in the open ocean?

Most tsunamis travel at speeds of 500 to 800 kilometers per hour (approximately 310 to 500 miles per hour) in the open ocean. This high speed is comparable to that of a commercial jetliner, allowing tsunamis to cover vast distances quickly. However, their height is usually only a few feet, making them difficult to detect until they approach shallower coastal waters. As they near land, their speed decreases, but their height can increase dramatically, leading to potentially devastating impacts.


How fast does the pacific plate travel per year?

7 cm a year


4 How far and at what speeds can tsunamis travel?

One went from Krakatoa in Indonesia to England. They can move as fast as a commercial jet plane.


How fast can tsunamis get?

Tsunamis can travel as fast as jet planes over deep ocean waters, reaching speeds of up to 500-600 miles per hour (800-1000 kilometers per hour). However, as they approach shallow waters near coastlines, their speed decreases, causing the height of the wave to increase dramatically.


What happens if earthquake is under ocean?

If an earthquake occurs under the ocean, it can trigger a tsunami by displacing a large volume of water. Tsunamis are fast-moving waves that can travel great distances across the ocean and cause devastating damage when they reach the coastline. Additionally, submarine earthquakes can also pose a risk to undersea infrastructure such as cables and pipelines.


Where do tsunami's take place?

most tsunamis take place in the Pacific Ring of Fire but the can travel distances at a very fast speed so other places that are close to the ring of fire are at a risk as well


How fast does a Tsunami go?

actualy they go about 300-400 miles per hour. yeah pretty fast!^ I know that the waves from the tsunami in Japan, were travelling across the ocean at speeds of 8000km.in deep open sea, they can go 500 mph or more
