  3. How an Earthquake is a occurs An Earthquake can occur when two plates slide past each other or collide against each other.80% of earthquakes occur near The Pacific Ocean. The area around The Pacific Ocean is commonly known as the “Pacific Ring of Fire”.The place where an earthquake occurs under ground is known as the Focus.The Epicentre is the area on land where the Earthquake occurs the closer you are to the epicentre the bigger the damage you should except.Sometimes small earthquakes occur these are called Tremors.

  4. The Japanese Earthquake 2011 The Japenese Earthquake of 2011 also known as the Great East Japenese Earthquake occurred on the 11th March 2011 off the coast of Tohoku off the coast of Japan at approx 14:46 JST (Japan Standerd Time) was the most powerful Earhquake to ever hit Japan and it was in the top 5 most powerful earthquakes of all time messuring 9.0 on the magniutde scale.The earthquake also caused a large tsunami as one of there thousand aftershocks.The Earthquake lasted 6 minutes but devastated the whole world.

  5. Nuclear Power Plant Due to the Earthquake a large tsunami occurred after the earthquake causing many nuclear disasters in the local powerplant Fukushima.This affected many residents near by causing thousands of people to evacuate. Many electrical generators were taken down, and at least three nuclear reactors suffered explosions due to hydrogen gas that had built up within their outer containment buildings after cooling system failure.

  6. Devastation • Unfortunatly after these attacks 15,878 died,6,126 injured and 2,713 missing many were also left homeless.Japans National Police Agency said on April 3rd 2011,that 45,700 buildings were destroyed and 144,300 were damaged by the earthquake or the tsunami . 24- 25 million tons of debree were left after these disasters.

  7. Richter Scale The Richter magnitude scale(often shortened to Richter Scale) is one of a number of ways that have been developed to assign a single number to quantify the energy contained in an earthquake. The scale is a base-10 logarithmic scale. The magnitude is defined as the logarithm of the ratio of theamplitude of waves measured by a seismograph to an arbitrary small amplitude. An earthquake that measures 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0, and corresponds to a 31.6 times larger release of energy.

  8. Intresting Facts and Pictures • Speed at which the Pacific Plate is smashing into the Japanese island arc: 8.9 centimeters (3.5 inches) per year. • Years since an earthquake of this magnitude has hit the plate boundary of Japan: 1,200. • Distance that the island of Honshu appears to have moved after the quake: 2.4 meters. • Top speed of a tsunami over the open ocean: About 800 kilometers per hour.
