Talking about natural disaster, an earthquake is one of the worst natural disasters that could ever happen in a country. The damaged and the lost can break every citizen who had experienced facing the earthquake. The strength or the magnitude of an earthquake is measured by a unit called Richter scale. The device to measure it is called as seismometer. In today’s article, you will find out 10 largest earthquake ever recorded with the biggest magnitude ever happened.
An earthquake happens when there are two blocks of the earth unexpectedly slip through one another. The surface when the blocks slip is called as fault plane or fault. Meanwhile, the location below the surface of the earth where theearthquake happens is called as hypocenter. And the location directly above the hypocenter on the earth’s surface is called as epicenter. Usually earthquakes have foreshocks that mean larger earthquake happens in the same place as the smaller earthquakes. The main earthquake which is the largest one is called as main shock. It is always followed by aftershocks. Aftershocks can continue even for weeks, months and years after the main shock happened. The duration of them depends on the size of the main shock.
The largest earthquake ever recorded
Can you guess which country has the largest earthquake ever recorded? It happened in southern Chile on May 22nd, 1960. The earthquake had a magnitude of 9.5 which documented by the US Geology Survey. This largest earthquakeis well-known as the Great Chilean Earthquake or the 1960 Valdivia Earthquake since the location happened near Valdivia. According from the US Geological Survey, this earthquake is the largest earthquake ever recorded of the 20thcentury.
Local damage from Tsunamis and Ground Motion
The government of the Chilean stated that more than 2,000,000 people were homeless because this greatest natural disaster. Most of the deaths and damage were also caused by the series of tsunamis because of this earthquake. The giant waves swept everything nearby coastal area right after the earthquake happened. They swept all buildings and homes and also drowned many people without warning.
The damage because of tsunami
Tsunami is one of the several earthquakes that had killed big amount of people in the distant locations. It is generated by the earthquake itself that could travel across the Pacific Ocean with the speed more than 200 miles per hour. The damage cause by the tsunami can sweep all buildings even skyscraper, boats and people since the waves can be up to 18 feet high.
