1. 1. Mount Unzen, erupted in 1972. Its located in Japan near the Shimabara Peninsula. The earthquake accompanied by an eruption, triggered the collapse of the lava dome. Which then created lava deposits, that created a landslide. The landslide went through the nearby city of Shimabara. Then out to sea, creating a tsunami that tore through two cities and back to Shimabara. Approximately 15,000 people was killed, making it the deadliest volcano in Japan's history. Many of the deaths are due to the tsunami. The eruption caused Plants, animals and aquatic life to be threatened. However, Japans soil is rich, therefore the plants can grow back quickly. Other dangerous effect of this volcano are due to the ash that the wind carries to nearby countries and cities. When the ashes are inhaled it may cause illnesses. …show more content…
2. Currently Mount Unzen is still active. However, there hasn't been an eruption since 1996.
3. 3. Volcanoes are created because of the movement in the earths tectonic plates. When two tectonic plates move apart the magma (rocks) that are created in the mantle flows upward causing an eruption of gases. Florida is located on the North American Tectonic Plate. Which is referred to as the passive plate. This means its not an active plate. Therefore, the chances of a volcano is highly unlikely. California is located on the border of the Pacific and Northern Plates, which are active plates. This is why California have volcanoes and Florida
Lassen Peak and Mount St. Helens are the only two volcanoes in the contiguous United States to erupt during the 20th century.
...815 eruption of Mount Tambora. With over 70,000 deaths and a rating of 7 on the volcanic exclusivity index, this eruption is one of the largest in recorded history. Not only did this volcano cause destruction in Indonesia but the consequences were further felt around the world, as volcanic ash and sulphuric gases were dumped into the stratosphere causing a global climate shift. Dark clouds covered the sun, and dramatic weather changes ensued. Flash floods frequently occurred wiping out a great deal of crop eventually causing prices to skyrocket. Disease began to spread due to malnourishment and unsanitary living conditions. Eventually these consequences subsided and citizens began to migrate towards Mount Tambora once again. Today the government has placed seismic sensors are set up in the most volatile areas to ensure preparedness in the event of another volcano.
The actual eruption of Vesuvius was of the explosive nature. The catastrophic eruption in 79 AD took place in a period that is estimated to have unfolded over 25 hours and took place in two stages (Museum tim...
Volcanoes have always been a mysterious wonder of the world. Volcanoes have shaped the landscape and the very ground that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period.
Mauna Loa is located on a hot spot in the Pacific Ocean. It is not near a plate boundary, in fact it is 3,200 km from the nearest plate boundary, and is situated in the middle of the Pacific tectonic plate. This is actually a rarity, as 90% of volcanoes are along a tectonic plate boundary. A hot spot occurs where long, stationary vertical pools of magma rise up and towards the plate. Movement of the tectonic plates above the hot spot created Mauna Loa, along with the other Hawaiian volcanoes. The older Hawaiian Islands were once above this stationary hot spot, but have been carried northwest by the slowly moving Pacific plate. As the plate moves, it carries the previously formed, older, volcanoes with it, creating a trail of younger, new volcanoes behind. The islands are lined up along the Hawaiian Ridge-Emperor Seamounts chain, which is 3,750 miles and includes Kauai, Maui, Oahu and Hawai’i, from north to south, respectively. There are around 80 volcanoes in this chain; most of them underwater, consequently the term seamount refer to submarine volcanoes. Three volcanoes of Hawai’i, Mauna Loa, Kilauea and Loihi seamount, are all currently sharing the Hawaiian hot spot. Although, recent evidence has shown that all three volcanoes use have separate plumbing systems to expel the lava from the pool of magma deep below them. It has also been suggested that Loihi is slowly moving Mauna Loa from the center of the island, thus shifting directly over the hot spot. The closer to the hot spot a volcano is, the more active it will be. The Hawaiian hot spot has laid down layers of lava, building up enormous islands from the ocean floor.

New Zealand has many volcanoes because it is on two separate tectonic plates, the Australian and the Indo-Pacific plates, that cut right through Wellington. In the North Island, the Indo-Pacific plate goes under the Australian plate. This forms a subduction zone as the denser crust goes under the less dense one. In the South island the opposite happens. Because of this plate arrangement, it creates many unusual land features in New Zealand such as, the Alpine Fault and the Puysegur Trench. New Zealand is also on the Ring of Fire which is a horseshoe like formation of volcanoes in the Pacific Ocean. This means that New Zealand is home to many of the world's volcanoes.
Over the centuries, the making of the Big Island as we know it today eventually entailed the growth and conjoining of six separate volcanoes, building all the way up from the seafloor, some 18,000 feet below the ocean’s surface. These volcanoes, from northwest to southeast, are named Mahukona, Kohala, Mauna Kea, Hualalai, Mauna Loa and Kilauea, and become younger as one moves north to south. Mahukona Volcano, just off the Big Island’s northwest coast, was the first volcano to start forming. Now submerged beneath the surface of the ocean because it is sinking into the Earth’s crust under its own vast weight, Mahukona is no longer visible. As the Pacific Plate slowly continued moving northwestward over the hotspot, the location of the rising magma moved relatively southeastward, and through time the rest of the Big Island volcanoes formed along that path.After Mahukona, Kohala Volcano, the precursor to today’s Kohala Mountain, erupted next. As Kohala Volcano emerged from the sea and joined with Mahukona, a much larger Big
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Krakatau (Krakatoa), is said to have created the worst volcanic eruptions in history, in 1883. Ancient Krakatoa formed in 416 A.D. and still exists today in Indonesia. That same explosion, in 1883, created 130 feet tsunamis, which destroyed 130 coastal homes, two docks (India and Australia), and killed about 36,000 people. It created very loud sounds and was heard as far away as Madasagascar, about 3,000 miles away from Java, where Krakatau was. Some people even believe that it may have been the reason for the drop in temperature and the spectacular sunsets for the next three years.
known volcanoes, 70 can be expected to erupt each year with at least one large eruption each
This is the most famous eruption that has been produced from the volcano of Pompeii and arguably one of the most well appraised volcanic eruptions in the world. On this day the volcanic eruption had wiped out the entire town of Pompeii, Italy and destroyed parts of...
10th of June soon after midnight. Mt Tarawera light up like fireworks. BOOM! Molten rock cam flying out of the crater. People as far as Blenheim could hear this thunder like noises but had no idea what it could be. Although the people of Rotorua knew exactly what has happening Mount Tarawera was erupting! The Mt. Tarawera eruption was the largest eruption in New Zealand for 800 years.
Mount Vesuvius, on the west coast of Italy, is the only active volcano on mainland Europe. It is best known because of the eruption in A.D. 79 that destroyed the city of Pompeii. Mount Vesuvius is considered to be one of the most dangerous volcanoes in the world due to the large population of the city of Naples and the surrounding towns on the slopes nearby.
The death toll climbs to over 10,000 and is still rising (Branigan 2). The disaster in Japan began without warning on Friday March 11, 2011 at 2:46pm with a 9.0 magnitude earthquake, the strongest ever recorded in the country (Fackler 3). A massive thirty-three foot high tsunami, generated by the earthquake, swept over lands in northern Japan, taking objects and debris with it. To make matters worse, the tsunami caused the cooling systems at several nuclear power plants to fail. The disaster in Japan was a tragic event, and it had a plethora of causes and effects.
