1. Largest Earthquake recorded  The largest earthquake ( magnitude 9.5) of the 20th century occurred on May 22, 1960 off the coast of South Central Chile.  It generated one of the most destructive Pacific-wide tsunamis. Huge tsunami waves measuring as high as 25 meters, arrived within 10 to 15 minutes after the earthquake.  Approximately 1,655 killed, 3,000 injured, 2,000,000 homeless, and $550 million damage in southern Chile; 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.

2. 1964 Great Alaska Earthquake  On March 27, 1964, at 5:36 p.m. a great earthquake of magnitude 9.2 occurred in Prince William Sound region of Alaska.  This earthquake is the second largest earthquake ever recorded in the world.  The duration of rupture lasted approximately 4 minutes.  In the first day there were 11 aftershocks with magnitudes greater than 6.0; in the next three weeks there were 9 more. Smaller aftershocks continued for more than a year

3.  The damage totaled 300- 400 million dollars (1964 dollars).  The number of deaths from the earthquake totaled 131; 115 in Alaska and 16 in Oregon and California.  The death toll was extremely small for a quake of this magnitude due to low population density, the time of day and the fact that it was a holiday (it was Good Friday), and the type of material used to construct many buildings (wood). The Great 1964 Alaska earthquake generated catastrophic tsunami waves that devastated many towns in the Prince William Sound area of Alaska, along the Gulf of Alaska, along the West Coast of Canada and the United States, and in the Hawaiian islands. In Alaska, the tsunami height measurements varied from 6.1 m at Kodiak Island, 9.1 m at Valdez, 24.2 m at Blackstone Bay, and 27.4 m at Chenega

4. Deadliest Earthquakes January 23, 1556-China  The earthquake occurred near Huaxian, Shaanxi (formerly Shensi), China,. More than 830,000 people were killed.  Had an estimated magnitude of 8  Damage extended as far away as Taiyuan, the capital of Shanxi (formerly Shansi) and about 270 miles (430 km) northeast of the epicenter. There are felt reports as far away as Liuyang in Hunan, more than 500 miles (800 km) away.  Geological effects reported with this earthquake included ground fissures, uplift, subsidence, sandblows, liquefaction and landslides. Most towns in the damage area reported city walls collapsed, most to all houses collapsed and many of the towns reported ground fissures with water gushing out (ie. liquefaction and sandblows).

5. December 26, 2004 Off the coast of Northern Sumatra  a magnitude 9 undersea earthquake shook the sea bed off the north west coast of Sumatra. Within hours multiple tsunamis had swept across the Indian Ocean ravaging coastal regions and killing over 220,000 people.

11. Hildasan, 50, net-maker I was repairing some fishing nets in the harbour when I saw the waters rising. I'd never seen anything like it. I began to run for my life - I knew something was very wrong. The rumbling noise, the rising water, just didn't make sense. As I ran inland the sea seemed to be roaring in the background.

13. Sundar Raj, 21, fisherman I was sleeping in our boat when the sea began making a rumbling sound. I saw the water level rising. I jumped into the water and tied my boat to the wharf as the waves began lashing me from behind. I climbed on to the jetty and ran.
