### What is the maximum speed of a tsunami?

“The tsunami not’is did not come by itself, it dragged cars, tree trunks, houses”, explained the BNPB spokesperson, adding that in the open sea, the waves of the tsunami were able to reach a speed 800 km/h.

### How fast does a tsunami travel?

The waves of tsunami spread in the open sea at gears of several hundred km/h (180 km/h for the tsunami September 2, 1992 in Nicaragua, 800-900 km/h for the tsunami of December 26, 2004 in the Indian Ocean).

### How far does a tsunami travel?

The spatial period or wavelength is most often between 60 km (period of 10 min and depth of 1 km), typical of tsunamis non-tectonic localities, and 870 km (60 min period and 6 km depth), typical of tsunamis of tectonic origin.

### What magnitude for a tsunami?

One tsunami is caused by an underwater earthquake, ‘a d-magnitudeat least 6.5. HAS leave ‘a magnitude 8, the tsunami generated can be devastating, depending on the relief approaching the coast, the tide, the wave period…

### How fast are tsunami waves?

In deep water and offshore, the waves of tsunami waves can travel at more than 800 km/h, while not exceeding a few decimeters on the surface. However, as they approach the coast, their speed decreases.

### What is the travel time of a tsunami?

Travel time of a tsunami generated by an earthquake off the coast of Chile: each curve represents one hour travel time of the tsunami. In regions where the depth of the ocean reaches more than 6000 meters, the imperceptible waves of the tsunami can move at the speed of an airplane, approximately 900 km/hour.

### What is the Variable Depth Tsunami?

Tsunamis created by landslides or the collapse of a volcano often have shorter periods, from a few minutes to a quarter of an hour. . Fig. 4 – Propagation of the tsunami at variable depth: increase in amplitude, decrease in wavelength and speed in shallow medium.

### How high is a tsunami?

In the deep ocean, destructive tsunamis can be small – often a few centimeters to tens of centimeters high – and are never seen or felt by ships. But, when the tsunami hits the shoreline in shallow water, the wave height can increase rapidly.
