Yes, echoes can occur underwater. When a sound wave hits an object, such as the seabed or a submerged object, the sound wave bounces off and returns to the source, creating an echo. The depth and composition of the water, as well as the frequency of the sound wave, can affect the strength and clarity of the echo.
it measures the depth under water
Yes and a great many of the earth's volcanoes are underwater.
A really big iPhone
Yes, they do.
Repeated echoes are called reverberations. They occur when sound waves reflect off surfaces multiple times, creating a persistence of sound in a space.
Sound travels through water. Sound reflects from objects with different densities. You can listen for the echoes.
it is caused by underwater disturbance
Underwater is an adjective used for things that occur characteristically under water, which is an adverbial phrase.

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.
Well, tsunamis are the effect of an earthquake underwater. When two tectonic plates collide or rub against each other, earthquakes occur. So, when it's underwater, tons of water is rushed towards the shore, and a tsunami occurs.
it happened by an underwater megathrust earthquake in the indian ocean.
