Earthquakes, among nature's most powerful phenomena, represent the formidable might of the Earth's inner workings. These seismic events, often characterized by tremors and surface upheavals, can result in widespread devastation, loss of life, and a cascade of disasters such as tsunamis, landslides, and fires.
Measured on the Richter scale, earthquakes' potency is gauged through magnitudes, representing the logarithm of seismic wave amplitudes recorded by seismographs. The higher the magnitude, the greater the energy released by the earthquake.
Several earthquakes across the globe have recorded staggering magnitudes, some exceeding 9 on the Richter scale. Megathrust earthquakes, with magnitudes surpassing 8 on the Richter scale, occur due to friction between tectonic plates pressing against each other, predominantly in subduction zones where oceanic plates dive beneath continental or other oceanic plates.
Here's a captivating glimpse into the top 10 largest earthquakes recorded in history, spanning from 1900 to 2024:

6. Maule Earthquake, Chile, February 27, 2010 (M 8.8)
Ranking as the sixth-largest earthquake in history, the Maule earthquake struck with a magnitude of 8.8 on the Richter scale. Unfolding off the coast of Maule, Chile, the quake endured for 3 minutes, causing widespread devastation across Chile, particularly in Concepcion, Talca, Santiago, Valparaiso, and Rancagua.
Resulting in approximately 525 fatalities, injuring 12,000 individuals, and displacing 800,000 residents, the earthquake also triggered a tsunami that struck Chile, Peru, Ecuador, Colombia, Panama, Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Mexico, Hawaii, Japan, Russia, the Philippines, and Indonesia. This tsunami claimed around 200 lives, mostly in Chile, while inducing notable Earth axis shifts and accelerating Earth's rotation.
5. Kamchatka Earthquake, Russia, November 4, 1952 (M 9.0)
The Kamchatka earthquake, registering at a magnitude of 9.0 on the Richter scale, stands as the fifth-largest earthquake in recorded history. Unfolding off the coast of Kamchatka, Russia, the quake lasted for 5 minutes, despite causing no damage or casualties on land due to its remote location.
However, the earthquake triggered a tsunami that inundated Pacific coastlines, including Hawaii, Alaska, California, Oregon, and Chile. This tsunami claimed approximately 15 lives, primarily in Hawaii, and caused significant geographical alterations, such as land uplifts or depressions up to 4 meters and the formation of new lakes.
