It lasted for 10 minutes but resulted in tsunamis that affect many regions. The epicenter of the earthquake was near Lumaco, which is approximately 570 kilometers away from Valdivia, therefore making it the most affected region. The total number of fatalities was around 5000, and the monetary loss was from US$400 million to $800 million.

2. 1964 Alaskan earthquake

The earthquake caused ground fissures, collapsing structures, and tsunamis all over Alaska. There were about 131 deaths, even though it lasted for four minutes and thirty-eight seconds. The magnitude of the earthquake was 9.2 making it the most powerful earthquake recorded in North American history.

3. 2004 Indian Ocean earthquake

The 2004 Indian Ocean earthquake, also known as the Boxing Day Tsunami occurred on 26 December. The epicenter of the earthquake was the west coast of northern Sumatra and the magnitude of the earthquake was 9.1–9.3 Mw. The earthquake led to massive tsunami waves that grew up to 30 m (100 ft) high. The tsunamis generated killed almost 227,898 people in 14 countries making it the deadliest disaster of the 21st century. 

4. 2011 Tohoku earthquake

The 2011 Tohoku earthquake that took place undersea had a magnitude of 9.0–9.1. The earthquake occurred on the off coast of Japan on Friday 11th March 2011.

The disaster resulted in severe damages from La Serena to Chillan and, also 1,000 km (620 mi) of Chile’s coastline. The amounts of deaths were quite less but, a strong foreshock had caused people to leave their homes. 

6. 1952 Severo-Kurilsk earthquake

1952 Severo-Kurilsk earthquake occurred at the coast of the Kamchatka Peninsula and has a magnitude of 9.0 Mw. The earthquake leads to massive tsunamis that affected the regions of Severo-Kurilsk, Kuril Islands, Sakhalin Oblast, Russian SFSR, and USSR.

8. 1700 Cascadia earthquake

The 1700 Cascadia earthquake which, struck the Cascadia subduction zone on January 26, had a magnitude of 8.7–9.2. The fault rupture that occurred had a length of about 1,000 kilometers. Since the earthquake took place a long time ago, there aren’t any specific details about them. Scientists continue to study such horrific events because they warn us about the threat that might take place in the future.
