This is an analysis on what is known to be the largest earthquake and biggest tsunami ever to hit Japan on March 11, 2011. The earthquake and tsunami Japans coast lies in ruins after the earthquake hit followed by the tsunami picking up everything in its path like cars, houses, and warehouses. Seismometers, strain gages, and title gages records the disaster. P-waves travel at four miles a second and within seconds warnings flash across the country. The S-waves shake the ground making earthquakes so damaging and the reactor core is shut down (Kerger, 2011.
The earthquake began off of the north-eastern coast of Honshu and caused catastrophic damage. The coastal areas were hammered by a “series of large tsunami waves that devastated many coastal areas of the country, most notably in the Tōhoku region (northeastern Honshu)”. (“Japan Earthquake and Tsunami of 2011”, 1) According to Encyclopedia Britannica… The epicentre was located some 80 miles (130 km) east of the city of Sendai, Miyagi prefecture, and the focus occurred at a depth of 18.6 miles (about 30 km) below the floor of the western Pacific Ocean. The earthquake was caused by the rupture of a stretch of the subduction zone associated with the Japan Trench, which separates the Eurasian Plate from the subducting Pacific Plate. (Some geologists argue that this portion of the Eurasian Plate is actually a fragment of the North American Plate called the Okhotsk microplate.)
The belt extends from Chile, northward along the South American coast through Central America, Mexico, the West Coast of the United States, and the southern part of Alaska, through the Aleutian Islands to Japan, the Philippine Islands, New Guinea, the island groups of the Southwest Pacific, and to New Zealand. This earthquake belt was responsible for 70,000 deaths in Peru in May 1970, and 65 deaths and a billion dollars' damage in California in February 1971. As disaster crews and scientists examine the havoc wrought in Haiti, questions emerge as to whether such a vastly destructive disaster could happen at home in the United States. Would citizens know how to react? Cities are located near dangerous earthquake zones all throughout the country, from the most infamous on the West Coast to potential time bombs in the Midwest and even on the Eastern Seaboard.
Geology The Loma Earthquake 1989 Name Course Date due An earthquake is a physical occurrence where vibrations are caused by underlying rocks that are breaking under a lot of stress. The rocks are situated under the earth’s crust and are mostly caused when two tectonic plates come together, and pressure is created along the fault lines. It is then released towards the earth’s surface resulting in an earthquake. In 1989, the Loma Earthquake occurred in the region of the Santa Cruz Mountains that caused a total number of 63 fatalities, 3,557 injured related cases. It also destroyed a lot of property which is estimated to be about $6 billion.
The earthquake occurred in the backarc region of the convergent boundary where the Pacific Plate subducted beneath the Eurasian Plate. The earthquake shaking caused moderately severe damage, VIII on the Mercalli scale. The jolting movement of the seabed made the water rise and fall, which set off a terrifying tsunami. The fast-moving waves spread in all directions. They hit Okushiri less than four minutes later.
The countries which were affected the most include Indonesia, Sri Lanka, India and Thailand. Some of the other countries that were affected were Somalia, Malaysia, South Africa, Madagascar and Kenya. The hardest hit area was the Aceh Province of Sumatra located in Northern Indonesia, which was the closest area to the earthquake that started the whole disaster. *when did it occur* On the 26th of December, at 7.59 am local time, an earthquake measuring 9 on the Richter scale is recorded off the coast of Sumatra, Indonesia. Buildings started shaking in Bangkok which was around 780 miles away from the earthquake.
Boscastle Flood Using the information you have been given summarise the MAIN causes and effects of the Boscastle Flood On the 16 August 2004 Boscastle suffered extensive damage after flash floods caused by an exceptional amount of rainfall that fell over 8 hours in the afternoon. The floods were recorded as the ‘worst’ in local history. Boscastle is a small village in Cornwall, South West England. The village is home to 800 residents. These were flash floods that caused the village to be shocked and un-prepared.
The Eastern Japan quake was caused by a 9.0 magnitude undersea earthquake that struck off the coast of Japan at 2.46 p.m on the 11th March 2011 (Friday). The epicenter was 72 kilometers east of the Peninsula of Tohoku at a depth of 32km. The earthquake triggered large destructive Tsunami waves of more than 10 meters that struck Japan quickly and travelled up to 10 km inland. Small Tsunami waves reached other countries as well like Hawaii after few hours. This tragedy has left more than 11,000 people dead with more than 15,000 people missing.

The shifting of the earth’s plates in the Indian Ocean on Dec. 26, 2004 caused a rupture more than 600 miles long, displacing the seafloor above the rupture by perhaps 10 yards horizontally and several yards vertically. As a result, trillions of tons of rock were moved along hundreds of miles and caused the planet to shudder with the largest magnitude earthquake in 40 years. Within hours of the earthquake, killer waves radiating from the epicentre slammed into the coastline of 11 Indian Ocean countries, damaging countries from east Africa to Thailand. A tsunami is a series of waves, and the first wave may not be the most dangerous. A tsunami “wave train” may come as surges five minutes to an hour apart.
