they can occur only in water.
they can occur in water and on land.
we can predict them.
underwater landslides can cause them.
dam failures can cause them.

They can occur only in water.

We can predict them.

Underwater landslides can cause them.

Explanation:

A tsunami is the result of abrupt tectonic processes in oceanic areas. When an interaction occurs between two tectonic plates, causing a high intensity earthquake in a marine relief, the result is the formation of a large wave, the tsunames. This is the main cause of this kind of natural disaster. The others are rare, and consist of falling asteroids in the water and eruptions of marine volcanoes. There are software capable of identifying tsunami formation. This is a work of geologists. For example, Japan's tsunami was forecast in 2011, but there were still many deaths.

They can occur only in water

Underwater landslides can cause them

dam failures can cause them

Explanation:

It is basically referring to where they form and not what they can hit, so they can not occur on land. Underwater landslides and dam failures create a giant ripple effect. Tsunamis are just massive ripples in water.
