Water displacement due to physical land movement causing an underwater wave in a ripple effect. A underwater wave is different from a regular wind driven surface wave in effect because when the underwater wave reach shallow waters it is forced up by forward motion causing a tsunami.

∙ 12y agoMost tsunamis seen these days were caused by earthquakes but one possibility is for a land-based volcano to break down and collapse, forcing large amounts of ash and debris into the water. This will cause a tsunami. Also an underwater volcano will cause a tsunami when they explode. The pressure generated will move the water.

What physical processes causes a Tsunamis?
usually and underwater volcano.
What do underwater volcanic eruptions cause?
Underwater eruptions cause tsunamis and cause lava to form and underwater ridge.
What are 3 underwater names that can cause tsunamis?
Underwater landslides, Underwater volcanic eruptions, and Underwater earthquakes
What are earthquakes tsunamis and volcano caused by?
They are all caused by the Earths The Earths Tectonic PLates. e.g When there is a crack or fracture in a tectonic plate the pressure slowley builds up until it if released. This can cause tsunamis if the plate is underwater or an earthquake if it is not.
How can volcanoes errupt under water?
The tectonic plates shifting is what causes an underwater volcano to erupt. Plate shifting is also the cause of tsunamis and earthquakes.

Why are tsunamis associated with earthquakes?
Well, earthquakes do cause tsunamis. But only underwater earthquakes. Plus, they have to be a transform plate boundary earthquake(caused by subduction).Any displacement of water will cause a tsunami. In short, some underwater earthquakes cause tsunamis.
Does underwater volcanoes cause tsunamis and later become islands?
no
Who is responsible when there is a Tsunami?
An earthquake is responsible 'cause underwater earthquakes cause tsunamis.

They are all caused by the Earths The Earths Tectonic PLates. e.g When there is a crack or fracture in a tectonic plate the pressure slowley builds up until it if released. This can cause tsunamis if the plate is underwater or an earthquake if it is not.
How can volcanoes errupt under water?
The tectonic plates shifting is what causes an underwater volcano to erupt. Plate shifting is also the cause of tsunamis and earthquakes.
What are underwater mountains caused by volcanoes?
An underwater volcano can cause pillow basalts and rare tsunamis. Underwater volcanoes are formed by hot spots in the Earth's mantle.
How are volcanoes earthquakes and tsunamis related?
A volcanic eruption can cause an earthquake and an earthquake underwater can cause a tsunami.
What are 2 ways tsusmasis are formed?
Tsunamis occur when the water in the ocean is displaced. There are several ways they can be formed. One is by underwater earthquakes, another is by underwater landslides, and a third way is by underwater volcano eruptions.
Why are tsunamis so powerful?
The events that cause tsunamis involve huge releases of energy. The main events causing tsunamis are-underwater volcanic eruption, earthquake or a landslide.
