    Volcanoes

    1. Mount Merapi, Gunung Merapi, is an active stratovolcano located on the border between Central Java and Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately 28 kilometres (17 mi) north of Yogyakarta city, and thousands of people live on the flanks of the volcano, with villages as high as 1,700 metres (5,600 ft) above sea level.

    2. Mount Unzen is an active volcanic group of several overlapping strato volcanoes, near the city of Shimabara, Nagasaki Prefecture, on the island of Kyūshū, Japan’s southernmost main island. In 1792, the collapse of one of its several lava domes triggered a mega tsunami that killed about 15,000 people in Japan’s worst-ever volcanic-related disaster. The volcano was most recently active from 1990 to 1995, and a large eruption in 1991 generated a pyroclastic flow that killed 43 people, including three volcanologists.

    3. Mount Pelée is an active volcano at the northern end of the island and French overseas department of Martinique in the Lesser Antilles island arc of the Caribbean. Its volcanic cone is composed of layers of volcanic ash and hardened lava. The stratovolcano is famous for its eruption in 1902 and the destruction that resulted, dubbed the worst volcanic disaster of the 20th century. The eruption killed about 30,000 people. Most deaths were caused by pyroclastic flows and occurred in the city of Saint-Pierre, which was, at that time, the largest city on the island.

    4. Galeras (Urcunina among the 16th-century indigenous people) is an Andean stratovolcano in the Colombian department of Nariño, near the departmental capital Pasto. Its summit rises 4,276 metres (14,029 ft) above sea level. It has erupted frequently since the Spanish conquest, with its first historical eruption being recorded on December 7, 1580. A 1993 eruption killed nine people, including six scientists who had descended into the volcano’s crater to sample gases. It is currently the most active volcano in Colombia.

    5. Mount Nyiragongo is a stratovolcano in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo, about 20 km north of the town of Goma and Lake Kivu and just west of the border with Rwanda.

    6. Mauna Loa is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaiʻi in the Pacific Ocean, and the largest on Earth in terms of volume and area covered. It is an active shield volcano, with a volume estimated at approximately 18,000 cubic miles (75,000 km3), although its peak is about 120 feet (37 m) lower than that of its neighbor, Mauna Kea.

    7. Mount Etna is an active stratovolcano on the east coast of Sicily, close to Messina and Catania. It is the tallest active volcano in Europe, currently standing 3,329 m (10,922 ft) high, though this varies with summit eruptions; the mountain is 21 m (69 ft) higher than it was in 1981.

    8. Llaima is the largest and most active volcano in Chile at 3,125 m. Llaima stands for “Bloody Veins” (in mapuche, Indian). It resembles the bloody veins when you see streams of glowing lava flowing from the peak.

    9. Redoubt is an active and recently eruptive stratovolcano in the U.S. state of Alaska. It stands at 2,700 m. It has reached its strongest activity in the 20th century in 1902, 1966 and 1989. During the last eruption in 2009, 6 explosions were recorded which sent an ash plume more than 9 miles into the air. This was the biggest volcanic emissions in nearly 20 years.

    10. Ruapehu is an active stratovolcano in New Zealand, standing at 2,797 m. It contains three summits with an active crater located between them. It is considered to be one of the world’s most active volcanoes and the largest active volcano in New Zealand. Ruapehu got its name from a Maori world which means “exploding abyss.” The last eruption is dated to the 25th of September in 2007 andit happened without warning.

  2. 1. The only known active volcano in Grenada is Kick 'Em Jenny, just north, between Grenada and Carriacou. Kick 'Em Jenny is a seamount volcano, and is 5 miles west of Ronde Island. The first recorded eruption was in 1939, when it was discovered. Before it was under the name of a small island called Diamond Rock. The name itself is a reference to the waters being extremely rough.

    2. Parinacota is a potentially active volcano on the border between Bolivia and Chile. It is part of the Nevados de Pachayata volcanic group. The other major tall feature of the group is the mountain of Pomerape. The volcano and Pomerape straddle the border between Lauca National Park of Chile, and the Sajama National Park of Bolivia. Sajama, on the Bolivian side, is the closest tour guide site, at 27 kilometers east. It is 20,817 feet high.

    3. The Irazu Volcano is an active volcano of Costa Rica, in the Cordillera Central, close to Cartago. It is the tallest volcano of Costa Rico, though Cerro Chirripo is the tallest mountain. From the top it is possible for one to see both the Atlantic and Pacific, though such clear days, are very rare indeed, and it is typical for the volcano's summit to be covered in ash.

    4. Izalco, is a stratovolcano on the side of the Santa Ana Volcano, which is located in western El Salvador. It is on the southern flank of the Santa Ana volcano, and last erupted in 1966. The land is used for production of coffee, cacao, and sugarcane. The Santa Ana Volcano or Ilamapetec is a volcano in the Santa Ana Department of El Salvador. It formed the Acajutla Peninsula. It last erupted in 2005.

    5. Eyjafjallajokull is the volcano that created the ash cloud, disrupting many flights, in April 2010. It is a stratovolcano, with its highest point being 5417 feet. It is fed by a magma chamber which in turn derives from the tectonic divergence of the Mid Atlantic Ridge. It is part of a chain of volcanoes stretching across Iceland. Its nearest active neighbors are Katla, to the northeast and Eldfell, in the island of Heimaey, to the southwest. Katla is under the Myrdalsjokull ice cap.

    6. Mount Tambora is an active stratovolcano, also known as a composite volcano, in Sumbawa, Indonesia. It is flanked to both the north and south, by oceanic crust, and Tambora was formed in the active subduction zone beneath it. This raised Mount Tambora as high as 14,100. It is rated a 7 on the volcanic explosivity index.

    7. Mount Popa is a volcano of 4981 feet and is located in the center of Burma 30 miles SW of Bagan. It can be seen from 40 miles away. Mount Popa is known for the Popa Taungkalat Shrine. It is regarded as an oasis in the dry zone of Myanmar, and plants trees and shrubs grow.

    8. Tupungato, one of the higher mountains of South America, is a massive stratovolcano dating to Pleistocene times. It lies on the border, between the Chilean metropolitan region, and the province of Mendoza, Argentina, and is near a major international highway, about 50 miles east of Chile. It is located about 62 miles south of Mount Aconcagua. Immediately to its south lies the active Tupungatito Volcano, which last erupted in 1987. The mountain gives its name to the Tupungato Department, and an important Argentine wine producing region. Star Dust, an aircraft, crashed into it in 1947.

    9. Mayon Volcano is an active stratovolcano in the island of Luzon, in the province of Albay, in the Bicol Region/Peninsula, Philippines. It is 6 miles from the Gulf of Albay and its longest uninterrupted explosion happened in 1897, when 400 people died. In 1984, 73,000 people were evacuated an there were no casualties, but 77 people died in 1993.

    10. The La Soufriere (the Sulferer), or the Soufriere Saint Vincent is an active volcano in Saint Vincent, in the Windward islands. It was the tallest mountain in the country until 1979, when the top blew off. It is 4049 feet.

  8. 1.Dormant since 1857, Mount St. Helens erupted on May 18, 1980 in one of the largest volcanic explosions in North American history.
    After a fissure appeared along the north side of the mountain, a great portion of the rock facing fell, followed by a blast of stone, ash, and poison gas from the mountain. Landslides ensued, covering local forestation and carrying debris nearly 20 mi (32 km). The disaster took 57 lives, wiped out substantial populations of elk, deer, bear, and coyote, and destroyed miles of vegetation.
    A second eruption occurred a week later, on May 25, and then again on April 11, 1981. The high summit of Mt. St. Helens was replaced by a horseshoe-shaped crater 2,460 ft (750 m) deep; the volcano lost about 3,770 ft (1,150 m) of elevation from the old peak to the new crater floor.

    2.Eighteen hundred four years—almost to the day—after Pompeii was buried, an even larger volcanic catastrophe occurred half a world away. On Aug. 26–28, 1883, Krakatau, between the Indonesian islands of Sumatra and Java, erupted, destroying two-thirds of the island and discharging an immense cloud of dust that spread across the Earth, lowering global temperature by as much as 1.2 degrees C the following year.
    Krakatau's explosions also produced forty-meter high tsunamis that hurled ashore pieces of coral weighing 600 tons, and whose residual waves were observed as far away as Cape Horn and England. More than 36,000 people died in the disaster.

    Volcanic Landforms

    1. There are many different types of volcanoes and volcanic landforms. The first type of volcano is a shield volcano. These volcanoes have gentle slopes and an oval shape, such as Kilauea and Mauna Loa. Another type of volcano is a stratovolcano, or composite volcanoes. Steep-sloped and violent, these volcanoes are dangerous because they sleep for a long time before waking up. Examples include Krakatoa and Vesuvius. The third type of volcano are cinder cones, which vary in slope and explosiveness. An example is the Paricutin Volcano in Mexico.

    2. A lava dome is a formation of rock formed by slow-moving magma solidifying over or near the lava vent. The surface of this formation is rough and spiny. Examples of famous lava domes include the one in Mount Saint Helens after the 1980 eruption.

    3. Calderas are large volcanic depressions caused by the collapse of a structure in volcano. They are caused by the emptying of a magma chamber below a structure. A caldera example includes the Crater Lake Caldera in Oregon which is 8 km in diameter and formed 6800 years ago. An island in the middle of the lake formed by a cinder cone is called Wizard Island.

    4. Resurgent domes are caused in calderas, when magma flows back into the magma chamber and uplifts the caldera. Examples of resurgent domes are found in the Yellowstone caldera, which is the third caldera to be formed in that area and covers most of Yellowstone National Park.

    5. Geysers, Fumaroles, and Hot Springs are caused by volcanoes too. Fumaroles are vents at which gases which are heated deep within Earth escape to the surface. They are only visible if the water vapor, which is the most common gas to come out of fumaroles, condenses. Examples of all three are found at Yellowstone National Park, where magma still lies underneath the surface.

  13. ACTIVE VOLCANOES OF CENTRAL AMERICA

    #1. Santa María Volcano, Guatemala
    Symmetrical, forest-covered Santa María volcano is one of the most prominent of a chain of large stratovolcanoes that rises dramatically above the Pacific coastal plain of Guatemala. Santa María volcano is a typical, moderate-sized (10 km³), basaltic-andesite stratovolcano. In 1902, a catastrophic Plinian eruption produced a crater on the south flank of the volcano, exposing 250 m of interbedded lava flows, laharic material, and pyroclastic deposits.

    #2. Pacaya Volcano, Guatemala
    Pacaya volcano near Guatemala City is one of Guatemala's most active volcanoes, and its frequent eruptions are often visible from Guatemala City. Typical activity in recent years includes strombolian activity, lava flow emission and intermittent violent phases of lava fountaining. Pacaya is a complex basaltic volcano constructed just outside the southern topographic rim of the 14 x 16 km Pleistocene Amatitlán caldera.

    #3. Arenal Volcano, Costa Rica
    Volcán Arenal, a beautiful, 1657-m high conical andesitic stratovolcano near Lake Arena, is the youngest and one of the most active stratovolcano in Costa Rica. It is famous for a large explosive eruption in 1968 that killed several people and threw incandescent bombs to 5 km distance from the vent. Arenal lies along a volcanic chain where activity has migrated to the NW over the past 2 million years, from the late-Pleistocene Los Perdidos lava domes through the Pleistocene-to-Holocene Chato volcano, which contains a 500-m-wide, lake-filled summit crater. The earliest known eruptions of Arenal took place about 7000 years ago, and it was active simulataneously with Cerro Chato volcano until the activity of Chato ended about 3500 years ago.


    #4. Coatepeque, El Salvador
    Coatepeque volcano is a large 7 x 10 km wide caldera 50 km west of San Salvador city. The caldera is elongated in SE-NW direction, with walls rising up to 800 m above the floor in its southwestern part. An up to 120 m deep and 5 km diameter lake occupies the eastern part of the caldera. Hot springs occur near the lake shores. The caldera formed by the collapse of several overlapping stratovolcanoes east of Santa Ana volcano, and part of Santa Ana itself, during major rhyolitic pumice eruptions between 72,000 and 51,000 years ago. Deposits from these eruptions form a large layer present in most of southwestern El Salvador and parts of Guatemala.

    #5. Cerro Negro, Nicaragua
    Cerro Negro, Central America's youngest volcano was born in April 1850 and is one of the region's most active volcanoes. It has been producing frequent strombolian eruptions, occasional lava fountains and lava flows, and powerful explosive eruptions every few decades. Cerro Negro is the largest, southernmost, and most recent of a group of 4 young cinder cones that formed along a NNW-SSE-trending line in the central Marrabios Range 5 km NW of Las Pilas volcano. The volcano consists of a black ("negro") basaltic cinder cone with associated lava flows, including an aa flow field reaching 4 km to the NE and SW.

    #6. Fuego Volcano, Guatemala
    Fuego, one of Central America's most active volcanoes, is one of three large stratovolcanoes overlooking Guatemala's former capital, Antigua. It typically has strombolian activity and sometimes phases of intense lava fountaining, producing tall ash plumes and dangerous pyroclastic flows. Collapse of the ancestral Meseta volcano about 8,500 years ago produced a massive debris avalanche that traveled about 50 km onto the Pacific coastal plain. Growth of the modern Fuego volcano followed, continuing the southward migration of volcanism that began at Acatenango, the northern twin volcano of Fuego.

    #7. Ilopango, El Salvador
    Ilopango volcano is a 8x11 km wide caldera at the eastern margin of San Salvador city, El Salvador. It is elongated to the east, has 150-500 m high walls and contains the scenic Lake Ilopango, one of El Salvador's largest. The caldera is the result of at least 4 large plinian eruptions over the past few tens of thousands years. The lastest of these occurred in the 5th centruy AD. A historic eruption in 1879-80 formed Islas Quemadas ("burnt islands"), a group of islands in the center of the lake, corresponding to the summit of a mostly submerged post-caldera lava dome.

    #8. Izalco, El Salvador
    Izalco volcano was born in 1770 and is the youngest volcano in El Slavador. It formed on the southern flank of Santa Ana volcano located 45 km NW of San Salvador city. Frequent strombolian eruptions and sometimes lava flows have built a largely unvegetated cone 650 m high which contains a 250 m wide and 50 m deep summit crater. Volcán Izalco was frequently active between 1770 and 1966, but has been in its longest repose interval of its short history since then. Similarly to Stromboli volcano in Italy, it acquired the nickname of "El Faro", the "Lighthouse of the Pacific", because of its frequent strombolian eruptions that provided a natural night-time beacon for ships. Izalco is one of the most frequently active volcanoes in North and Central America

    #9. San Miguel, El Salvador
    San Miguel volcano (also known locally as Chaparrastique) in eastern El Salvador is a symmetrical stratovolcano and one of the most active volcanoes of the country. It rises majestically from near sea level to 2130 m elevation and forms a prominent land mark. The volcano's summit lacks vegetation due to frequent eruptions, but its flanks are largely covered with coffee plantations. San Miguel has a broad, deep crater complex, which has frequently changed morphology during historic eruptions recorded since the early 16th century.

    #10. Tacaná Volcano, Guatemala
    Tacaná volcano on the Mexican-Guatemalan border is a symmetrical stratovolcano rising 1800 m above its base and forms the NW end of the Central American Volcanic Belt. Tacana consists of overlapping volcanic edifices, reflecting a migration of vents from the NE to the SW over time. The youngest vent is the San Antonio lava dome in a crater on the upper SW flank, which was the site of most recent activity. Historic eruptions of Tacaná were small phreatic explosions in 1855, 1878, 1949–1950 and 1986, from both Tacaná and San Antonio. The eruption in 1950 was the largest and produced pyroclastic flows. Active fumaroles are found at 3600 m altitude and hot springs in various locations at the base of the volcano.
