It erupted in 1970, 1980, 1981, 1991, and the most recent eruption occurred in 2000 and lasted for 12 days. The volcano has been around for 7000 years and has been blowing up randomly ever since. Apparently about 2800 years ago, Mount Hekla had its largest eruption, and traces of the blast have been found as far as Scandinavia. Mount Katla is located in the most southern portion of Iceland, which is a mountain recently known for causing flooding when it melted glaciers on top of it. Due to all of Iceland’s volcanic activity, there is also a great deal of glacial activity.
The initial impact was devastating which left about 300,000 people homeless out of a population of about 410,000. Many of the people were evacuated to nearby cities, and the others lived in makeshift tents on the beach of North beach. In fact years later in 1908 these refugee camps were still in operation. The overall cost of the damages was estimated at the time to be 400 million US Dollars (around 8.2 Billion present Dollars). The fires that were a direct result from the main shock and the aftershocks were just as damaging because of the uncontrollable burning from ruptured gas lines.
Indeed, Chaitén was a major concern to both the airline industry and the neighbouring country of Argentina. In the first week of the current eruption, five airplanes encountered eruption-cloud ash, and several sustained significant engine damage. Airports in Chile, Argentina and Uruguay, up to 2,300 km from the volcano, were forced to close or cancel flights. In addition, volcanic ash from the eruption clouds caused ground transportation and health problems in Chile and Argentina. There were several hundred domestic flights in Argentina and Chile and several dozen international flights from Santiago, Chile and Buenos Aires, Argentina cancelled.
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.
Mauna Loa has an estimated time of six years between each eruption, but on March 25, 2009 The Hawaiian Volcano Observatory celebrated the 25th anniversary of the volcanoes last eruption in 1984. Mauna Loa is a shield volcano, the world’s largest, but although it’s active history the volcano has been quite for 2 and half decades. The crater at the mountains summit (Moku’aweoweo) is the main reason Mauna Loa has been erupting for 100,000 years if not more. Mauna Loa produces many types of flows including a’a, pahoehoe and lesser
The earthquake’s strongest point lasted for around 8-10 minutes. The tsunami created a permanent rise in global sea level by at least 0.1mm and it caused an inactive volcano located in the Leuser Mountain, Indonesia to active. Did you know the December 26, 2004 Indian Ocean tsunami was caused by an earthquake that is thought to have had the energy of 23,000 atomic bombs. *Location* The tsunami was located in 15 different countries. The countries which were affected the most include Indonesia, Sri Lanka, India and Thailand.
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.
In addition to loss of life and destruction of infrastructure, the tsunami caused a number of nuclear accidents and the associated evacuation zones affecting hundreds of thousands of residents. The overall cost could exceed US$300 billion, making it the most expensive natural disaster on record. 2. The full impact of Japan’s earthquake and tsunami will not be known for some time. The world’s focus at this time is on the enormous loss of life as a result of this tragedy.
The immediate aftermath of the reactor meltdown is seen here, this picture being taken a few days after the incident The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles, crippling the Soviet economy. The disaster began during a systems test on Saturday, 26 April 1986 at reactor number four of the Chernobyl plant, which is near the city of Prypiat and within a close proximity to the administrative border with Belarus and Dnieper river. There was a sudden power output surge, and when an emergency shutdown was attempted, a more extreme spike in power output occurred, which led to a reactor vessel rupture and a series of explosions. These events exposed the graphite moderator of the reactor to air, causing it to ignite. The resulting fire sent a plume of highly radioactive smoke fallout into the atmosphere and over an extensive geographical
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.
