A ferocious tsunami spawned by one of the largest earthquakes on record slammed Japan's eastern coast Friday, killing hundreds of people as it swept away ships, cars and homes while widespread fires burned out of control. Hours later, the tsunami hit Hawaii but did not cause major damage. Warnings blanketed the Pacific, putting areas on alert as far away as South America, Canada ...
An earthquake is a violent movement of the rocks in the Earth's crust. Earthquakes are usually quite brief, but may repeat over a long period of time.
There are large earthquakes and small earthquakes. Big earthquakes can take down buildings and cause death and injury. The study of earthquakes is called seismology.
When the earth moves in an earthquake, it can cause waves in the ocean, and if a wave grows large enough, it's called a "tsunami". A tsunami can cause just as much death and destruction as an earthquake. Landslides can happen, too. This is a very important part of the Earth's cycle.
Earthquakes are measured with a seismometer. The magnitude of an earthquake, and the intensity of shaking, is measured on a numerical scale. On the scale, 3 or less is scarcely noticeable, and magnitude 7 (or more) causes damage over a wide area.
The ancient Chinese also used a device that looked like a jar with dragons on the top surrounded by frogs with their mouths open. When an earthquake occurred, a ball fitted into each dragon's mouth would drop out of the dragon's mouth into the frog's. The position of the frog which received a ball indicated the direction of the earthquake.
Causes of earthquakes
Q: What is the strongest earthquake ever recorded?
A: The 1960 Valdivia earthquake or Great Chilean Earthquake (Spanish: Gran terremoto de Valdivia) of 22 May 1960 is to date the most powerful earthquake ever recorded, rating 9.5 on the moment magnitude scale. It occurred in the afternoon (19:11 GMT, 14:11 local time) and its resulting tsunami affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands in Alaska.
The Ten Strongest Earthquakes in the World
1.Chile, 22-May-1960, 9.5
2. Prince William Sound, Alaska, 28-Mar-1964, 9.2
3. Andreanof Islands, Aleutian Islands, 9-Mar-1957, 9.1
4. Kamchatka, 4-Nov-1952, 9
5. Off western coast of Sumatra, Indonesia, 26-Dec-2004, 9
6. Off the coast of Ecuador, 31-Jan-1906, 8.8
7. Rat Islands, Aleutian Islands, 4-Feb-1965, 8.7
8. Northern Sumatra, Indonesia, 28-Mar-2005,8.7
9. India-China border, 15-Aug-1950, 8.6
10. Kamchatka, 3-Feb-1923, 8.5
Surely Earthquake that hits Japan yesterday will be included in the Top 6 surpassing the record of Ecuador because it’s magnitude is 8.9..

A lot of entertainment news on Charlie Sheen of which I don't understand. One thing for sure he is no longer appearing on the TV sitcom 2 men and 1/2. ( hindi naman apektado ang mga pinoy dito dahil nakatutok sila sa Mara-Clara at Babaeng hampaslupa.)
After 25 years of EDSA People Power, it was only this year that the people of Egypt and Libya
realized that their leaders were all over-staying dictators. Hosni Mubarak just stepped down But Moamar Khadaffi or Gaddafi? Kadafi? Qaddafi? What's the correct spelling?
You say, Gaddafi, we say Qaddafi. Other variations on the leader of Libya include "Gathafi," "Kadafi," and "Gadafy," creating an unholy mess for newspaper editors.
