List of the strongest and deadliest earthquakes

February 27, 2010

    Maule Earthquake
On February 27, 2010 a magnitude 8.8 earthquake struck Maule, Chile causing widespread damage and casualties. The quake ranks as one of the ten strongest earthquakes ever recorded and was the most powerful earthquake worldwide since the 2004 Sumatran quake that triggered the massive Indian Ocean tsunami. The Maule was the strongest earthquake to strike Chile since the magnitude 9.5 which hit Valdivia on May 22, 1960.

A tsunami warning from the Maule quake has been issued for the U.S. west coast, British Columbia, and Alaska.

Strongest earthquakes

May 22, 1960: Magnitude 9.5 earthquake killed 1,655, injured 3,000, left 2,000,00 homeless, and caused $550 million damage in southern Chile; while the ensuing tsunami caused 61 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damage in Japan; 32 dead and missing in the Philippines; and $500,000 damage to the west coast of the United States.

    Earthquake triggers decline in a frog species

    (12/03/2007) In 1999 a 7.3 earthquake struck Nantou County at the center of quake-prone Taiwan. The earthquake caused considerable damage: over 2,000 people died and just under 45,000 houses were destroyed. The quake also devastated a subpopulation of riparian frogs, Rana swinhoana, which had been under scientific study for three years prior. This devastation allowed scientists the opportunity to study the population changes in a species affected suddenly and irretrievably by natural disaster.

    China uses snake-based earthquake prediction system

    (12/27/2006) A province in southern China has come up with a unique way to predict earthquakes: snakes. According to China Daily and as reported by Reuters, the earthquake bureau in Nanning, capital of the Guangxi province, has set up a 24-hour video feed to monitor the behavior of snakes at snake farms. The scientists say that snakes are particularly sensitive to vibrations caused by impending earthquakes.

    Some earthquakes may be linked to climate change

    (06/28/2006) Scientists say melting glaciers could induce tectonic activity. The reason? As ice melts and waters runs off, tremendous amounts of weight are lifted off of Earth's crust. As the newly freed crust settles back to its original, pre-glacier shape, it can cause seismic plates to slip and stimulate volcanic activity according to research into prehistoric earthquakes and volcanic activity.

March 27, 1964: Magnitude 9.2 quake in Prince William Sound, Alaska, and ensuing tsunami killed 128 people (tsunami 113, earthquake 15) and caused about $311 million in property loss. Anchorage, about 120 kilometers northwest of the epicenter, sustained the most severe property damage.

NOTE: Some sources list an earthquake that killed 300,000 people in Calcutta, India, on October 11, 1737.
Recent studies indicate that these casualties were most likely due to a cyclone, not an earthquake.
