Most are thrown up by undersea earthquakes associated with subduction, but they can also be triggered by major submarine mud-flows down steep slopes (turbidity flows). Major surface landslips into the sea may create surface waves causing local damage, but these diminish rapidly.
Normally undersea earthquakes causes giant waves, known as TSUNAMIS.
Tsunamis occur after an earthquake. Earthquakes that occur in the middle of the ocean can force a tsunami to make landfall.

A suitable name for a newspaper article on tsunamis could be "Unleashing the Power of Nature: Understanding Tsunamis." This title encapsulates the force and impact of tsunamis while hinting at the importance of comprehending these natural phenomena. It conveys the idea of exploring the science behind tsunamis and the need for awareness and preparedness in vulnerable regions.
Manmade causes of tsunamis can include underwater explosions, such as those caused by nuclear tests or volcanic eruptions, or underwater landslides triggered by activities like mining or construction. However, most tsunamis are caused by natural events like earthquakes or volcanic eruptions.

Gravity
Gravity is the natural force that causes rocks to fall or roll down a hill. As rocks are pulled by the force of gravity, they move downward due to the Earth's gravitational pull.
Tsunamis are primarily caused by underwater earthquakes, volcanic eruptions, or landslides which disturb the ocean floor. While weather conditions may influence the generation of tsunamis, such as in the case of typhoons or hurricanes, they are not the main cause. Human activities like underwater explosions or collapsing coastal structures can also trigger tsunamis but these are rarer occurrences compared to natural causes.
Gravity
The force of gravity causes the paperclip to fall into the tray. Gravity is the natural force that pulls objects toward the center of the Earth.
They don't have any role. Tsunamis are a natural phenomenon.
