GEOLOGY

Detailed explanation-1: -Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami. Most tsunamis are generated by shallow, great earthquakes at subductions zones. More than 80% of the world’s tsunamis occur in the Pacific along its Ring of Fire subduction zones.

Detailed explanation-2: -We can deduce that volcanoes and earthquakes are caused by tectonic plate movements, they both pose a significant danger to humans, and result in deadly secondary effects like tsunamis.

Detailed explanation-3: -Most landslides that generate tsunamis are caused by earthquakes, but other forces can cause unstable slopes to suddenly fail. Earthquakes that are not large enough to directly generate a tsunami may be large enough to cause a landslide that in turn can generate a tsunami.

Detailed explanation-4: -A tsunami is a series of enormous waves created by an underwater disturbance usually associated with earthquakes occurring below or near the ocean. Volcanic eruptions, submarine landslides, and coastal rock falls can also generate a tsunami, as can a large asteroid impacting the ocean.

Detailed explanation-5: -What is a tsunami? A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.
