Tsunamis are massive sea waves that are spawned from earthquakes generated underneath the ocean at tectonic plate boundaries. Although earthquakes are known to be the main cause of tsunamis, these enormous waves can occur due to occurrences such as rapid changes in the atmospheric pressure or volcanic eruptions. These waves are formed in a series, sometimes referred to as a “wave train.” There is never just one wave when a tsunami occurs. Typically, the first wave of a tsunami is not the strongest; waves that occur later on usually hold the most power and cause the most destruction. The waves of tsunamis can reach heights of up to one hundred feet when on land. Tsunami waves cause pervasive destruction when they travel across land. Tsunamis can form in any ocean; although this is true, according to National Geographic, “most tsunamis, about 80 percent, happen within the Pacific Ocean’s ‘Ring of Fire,’ a geologically active area where tectonic shifts make volcanoes and earthquakes common” (National Geographic). Tsunamis can last from only minutes to hours long. Tsunamis are one of the most dangerous natural disasters that can occur. It is crucial for one to know the background on tsunamis and how to stay safe during these monstrous natural disasters.
The word, tsunami, translates to “harbor wave.” This word’s origin is Japanese. When an earthquake occurs on the fault lines underneath an…
