More than three million people were killed in earthquakes in the last century alone.
All of the largest earthquakes on Earth during the 20th century occurred within the Pacific Rim.

Large Earthquakes That Are Expected To Happen In the Near Future



ALASKAN EARTHQUAKES: Each year Alaska has about 5,000 earthquakes, including 1,000 that measure above a magnitude of 3.5. Of the 10 strongest earthquakes ever recorded in the world, three were in Alaska, including the March 27, 1964, Good Friday earthquake, with a magnitude of 9.2. Alaska typically sees half a dozen quakes each year above magnitude 6.

CALIFORNIA - Los Angeles faces three times more earthquake damage each year than any other U.S. city and the West Coast bears a whopping 84 percent of all quake-related financial losses in the U.S.

CANADA - As many as 1,000 earthquakes-mostly below magnitude 3 -- occur in Canada every year. The most active regions are the western and southwestern regions of British Columbia, including Vancouver Island and the Queen Charlotte Islands, which are struck more than 200 times a year. However, eastern Canada has also been hit by major quakes, and experts cannot rule out a major earthquake hitting Toronto, Ottawa, or Montreal. The area immediately west of Vancouver, in British Columbia, is considered one of the most vulnerable in the country. It's here in the Juan de Fuca Strait that two tectonic plates- the North American Plate and the Juan de Fuca Plate-rub against each other. The North American Plate is gradually sliding underneath its neighbour; as it does, pressure builds along the plate boundary. Eventually, scientists say, this will cause "subduction earthquake," an incredibly powerful quake that may measure 9 on the Richter scale. Based on geological evidence in the region, it's believed that such quakes strike every 300 to 500 years. However, hundreds of minor earthquakes occur every year in the same region.

CENTRAL AMERICA - Jan 2001 - El Salvador is the scene of the 18th major earthquake in Central America since 1990.
In Central America significant earthquakes occur at the rate of two a year.
Major earthquakes in recent decades in Central America -
Jan. 13, 2001: El Salvador coast; magnitude 7.6; death toll uncertain.
Oct. 10, 1986: San Salvador, El Salvador; magnitude 7.5; about 1,500 killed.
Feb. 4, 1976: Guatemala; magnitude 7.5; 22,778 killed.
Dec. 23, 1972: Managua, Nicaragua; magnitude 6.2; 10,000 killed.

HAWAII - Earthquakes in Hawai`i are closely linked to volcanism. Thousands of earthquakes occur every year beneath the Island of Hawai`i.

INDIA - Most of the major earthquakes to rock India occur along what is known as the Himalayan Alpine Belt, where the piece of the earth's crust known as the Indian plate collides with the Eurasian plate, producing the world"s highest mountain range. Earthquakes measuring eight or above on the Richter scale occur in that area with a frequency of about once every 20 to 30 years.

IRAN - Experts say a major earthquake in the sprawling capital of Tehran is overdue - and at least one local professor says when it comes, it could kill 1.4 million people and wreck 60 percent of the city.

JAPAN - Earthquake activity increased in 2000.
