Earthquakes occur frequently in many parts of the world. These include low and high intensity. But a new study has found that the strongest and most powerful earthquake in the world occurred in the South American country of Chile. This happened 3800 years ago.
A study by researchers from the University of Southampton in the United Kingdom has revealed information about this ancient earthquake. The epicenter was reported below the Pacific Ocean floor, however; no tsunami alert was issued. It traveled 7,500 km and reached the far coast of New Zealand. Scientists say the waves were about 20 meters high.
Earthquakes are caused by the mutual movement and splitting of the earth’s plates. The epicenter was reported below the Pacific Ocean floor, however; no tsunami alert was issued. Remains of marine life, fish and marine life have been found in the Atacama Desert. How these came to be in the desert is a question that has puzzled scientists. Scientists now believe that the tsunami may have been caused by an ancient earthquake.
Archaeologists are still struggling to gather enough evidence before reaching the final conclusions about the location of the ancient Archaeological site in Atacama, Pablon de Pica. Scientists say the tsunami was the cause. Researchers also found that the tsunami, which was the aftermath of the quake, had reached New Zealand. The tsunami’s waves caused hundreds of meters of rock to sink off the coast of New Zealand.
As a country located in the Pacific Ring of Fire, earthquakes in Chile are a continuum. In 2010, a magnitude 8.8 earthquake shook the region. As part of this, a tsunami struck and many people were killed. The epicenter was reported below the Pacific Ocean floor, however; no tsunami alert was issued. This was the 1960 Valdivian earthquake. The quake, which measured 9.4 on the Richter scale, lasted about 10 minutes. The ensuing tsunami hit the coasts of Chile, Japan, Hawaii, the Philippines, New Zealand and Australia. An estimated 6,000 people were killed in the quake. The 8.0 magnitude earthquake of 1556 in Shanxi, China, had the largest number of trees. More than eight lakh people were killed in the tragedy.
