Tsunamis, like most natural disasters, are beyond human control. There are, however, a number of techniques that can minimize the harmful effects of tsunamis to the physical environment including built structures and to individuals and communities. Accompanied by an effective warning system, thoughtful design and strong community organization can reduce harm from Tsunamis and other natural disasters. Mitigation and prevention through: site strategies community development ecology. Avoid Inundation Areas: Site Buildings or infrastructure away from hazard area or locate on a high point. Slow Water: Forests, ditches, slopes, or berms can slow down waves and filter out debris.

The energy released from an earthquake can be up to 10, times more powerful than the first atomic bomb. Its side-effects can be:. Shaking of the ground caused by the passage of seismic waves , especially surface waves near the epicentre of the earthquake are responsible for the most damage during an earthquake. The intensity of ground shaking depends on:. When an earthquake event occurs, ground rupture is only where the fault zone moves. Those constructions built adjacent to the fault will survive while structures built across these zones will collapse. Avalanches, landslides, slumps and rock slides are triggered by ground shaking.
Case Study on Recent Tsunami
On the heels of a strong economy and shifting attitudes about workplace loyalty, the country experienced high rates of job switching in recent years. Amid mass layoffs, lockdowns, and uncertainty, many people are staying in their positions—thankful to have a job. Quit rates reached their lowest level in nine years in April , according to the Society of Human Resources Management.
A mystery surrounding one of the most destructive tsunamis of the 20 th Century just got more puzzling as a seafloor search failed to reveal the smoking gun scientists expected to find. On April Fools Day in an earthquake off the coast of the Aleutian Islands in Alaska spawned a series of waves known as a tsunami. One wave as high as a story building hit locally. Others raced across the Pacific, killing dozens and leaving a trail of destruction that stretched to California and even South America.
