How is a earthquakes are formed?

Answer 1

Earthquakes don't generate tsunamis - a tsunami is caused by different atmospheric pressure systems coming together. An underwater earthquake would generate a tidal wave, which is caused by the water displaced by the earthquake.

Answer 2

Underwater earthquakes are formed when two or more tectonic plates collide at sea, causing fault lines to slide. Underwater earthquakes also cause tsunamis as they force the water to push up, creating series of small tsunamis that continue to get bigger until they hit very shallow water or land; Unless of course it continues to travel at sea without striking either of these for a long period of time and slowly die down.
Most likely like regular earthquakes. The whole earth is like divided into many many tectonics plates. And when one moves and collides with another, an earthquake is formed.

Answer 3

Earthquakes are typically caused by the movement of tectonic plates along faults in the Earth's crust. When these plates suddenly release built-up stress and energy, it creates seismic waves that shake the ground. Other causes of earthquakes include volcanic activity, landslides, or human activities such as mining or reservoir-induced seismicity.

Answer 4

same as if it happened on land. the tectonic plates move a substantial amount and then it just happeneds

Answer 5

an earthquake occurs when two tectonic plates grind against eachother to for the earth to

shake.

Answer 6

A earthquke is formed when tectonic plates slide past one another with a great amount of friction resulting in the ground shaking.

Answer 7

earthquakes are formed when the earths boundaries over lap or cross another

Answer 8

when the techtonic plates shift.
