Which is the largest active volcano in the world? Where is it located and what are its characteristics? The following is the latest information I have collected. I hope it will be helpful to you.

Mauna Loa is the largest active volcano in the world.

Mauna Loa is an active shield volcano on the island of Hawaii. The large crater on the top of the mountain is called Mokawiowio, which means "Fire Island". Volcanic eruptions bring periodic and devastating damage. Wherever the magma flows, forests are burned, houses collapse, and transportation is cut off. Mauna Loa, with an altitude of 4205 meters, is the highest peak in Hawaii. There are often white clouds lingering on the top of the mountain, appearing and disappearing. As the Pacific Plate slowly drifts away, Mauna Loa is eventually pulled away from the hot spot and will stop erupting in 50 to 1 million years.

Mauna Loa (Hawaiian: Mauna Loa) is an active shield volcano on the island of Hawaii. It is one of the five volcanoes that formed Hawaii. Although its peak is 36 meters lower than the adjacent Mauna Kea volcano, Hawaiians still named it "Mauna Loa", which means "Long Mountain". Its capacity is estimated to be approximately 75,000 cubic kilometers (18,000 cubic miles). The lava erupting from Mauna Loa is very fluid, which results in the volcano's very slight slope.

Historical evolution

The Mauna Loa volcano has been erupting for at least 700,000 years and emerged from the sea level about 400,000 years ago. However, the oldest known rocks in the area are no more than 20 years old. Thousands of years. Magma from one of the hot spots beneath the island formed the Hawaiian island chain over the past tens of millions of years. As the Pacific Plate slowly drifts away, Mauna Loa is eventually pulled away from the hot spot and will stop erupting in 50 to 1 million years. The Array for Microwave Background Anisotropy (AMiBA), a collaboration between Taiwan and the United States, is located on the top of this mountain and began observing in October 2006. Latitude and longitude: 19.475?N 155.608?W Location

Hawaii Volcanoes National Park is located on the island of Hawaii in the state of Hawaii, covering an area of ??929 square kilometers. It mainly includes two modern volcanoes, Mauna Loye and Kilauea. active volcano. There are dense tropical rainforests here. There are also bats, Hawaiian geese, eagles, crows, Hawaiian white-bellied waterbirds and other animals. The two modern active volcanoes Kilauea and Mauna Loa are the main components of the park. At the same time, they are also the famous and distinctive symbols of Hawaii Volcanoes National Park.

Volcano Characteristics

Mauna Loa volcano is located in the middle of the Hawaiian Islands, with an altitude of 4170 meters and a height of about 9300 meters from the sea floor. There are often white clouds lingering on the top of the mountain, appearing and disappearing. Mauna Kea in the north of the island is 4,205 meters above sea level and is the highest peak in Hawaii. The world's highest observatory is located on the top of this mountain.

Mauna Loa is the largest volcano on the island. It is about 4200 meters high. The mountain gradually grew larger due to the continuous pouring of large amounts of lava. People call these lava "great architects". The large crater on the top of the mountain is called Mokaviovio, which means "Fire Island". Volcanic eruptions bring periodic and devastating damage. Wherever the magma flows, forests are burned, houses collapse, and transportation is cut off. The second largest volcano on the island is Kilauea. The mountain is about 3300 meters high. The top of the mountain is a saucer-shaped crater basin. The Hermomo crater in the basin, which means "Eternal Fire Palace", is the most famous. The lava in this crater often rises and falls like a tide. When a volcano erupts, lava not only overflows from the crater but also from the cracks in the rock formations. The orange-red lava flows with temperatures as high as 2,000 degrees Celsius, like a lying fire dragon. The sight is spectacular.

It is conical in shape. It rises from the bottom of the Pacific Ocean with a water depth of 6,000 meters. It is more than 10,000 meters high from the bottom of the sea to the top of the mountain, which is more than 1,000 meters higher than Mount Everest. Mauna Loa has erupted about 35 times, and there is still a crater on the top of the mountain. This crater erupted again in April 1984, and lava flowed 17 miles toward Hilo, the capital of Hawaii. Before the big eruption, there was a crater above the volcano. There was a huge heat wave, and nearby people first saw rolling dark clouds, followed by lightning and thunder, and then heavy rain.

In addition to these two volcanoes, dense tropical rain forests also grow on Hawaiian volcanoes. In the national park.

Isolated mountain

The volcano in the central and southern part of Hawaii Island in the United States, whose original name means "Long Mountain", is the largest in the world in the Hawaii Volcanoes National Park (established in 1916). One of the isolated mountains. It has an altitude of 4169 meters (13678 feet). Its dome is 120 kilometers (75 miles) long and 103 kilometers (64 miles) wide. The lava flows through an area of ??5120 square kilometers (2000 square miles). Mokuaweoweo covers an area of ??about 10 square kilometers (4 square miles) and is 152-183 meters (500-600 feet) deep. The top is often covered with ice and snow in winter.

It has erupted on average every three and a half years since 1832. Most of the eruptions are confined to the Mokuaveoweo crater, while the rest flow down along the fissure zones on the northeast or southwest sides. During the 1935 eruption, U.S. military aircraft dropped bombs on lava flows that threatened the city of Hilo. In June 1950, a 23-day flood of lava flowed down a 21-kilometer (13-mile) southwest fissure, destroying a small village. There were major eruptions at the top of the mountain in 1975 and 1984. Mauna Loa is an active volcano located on the island of Hawaii with an altitude of 4,169 meters and a volcanic volume of 75,000 cubic kilometers. It is the highest peak in the world from the bottom of the structure to the top. In the past 200 years, it has erupted approximately 35 times. There are still several pot-shaped craters and large calderas up to 2,700 meters wide on the top of the mountain. In November 1959, the Mauna Loa volcano erupted again. At that time, boiling lava bubbled out from a gap one and a half kilometers long. It lasted for a month. The highest height of the magma erupted exceeded that of New York. of the Empire State Building. In March 1984, the Mauna Loa volcano erupted again. The magnificent scenery was rare in the world and attracted tourists from all over the world. Mauna Loa is located in the center of the Hawaiian Islands, with an altitude of 4,170 meters and a height of about 9,300 meters from the sea floor. The width of the elliptical base of the seafloor has a long axis of 119 meters and a short axis of 85 kilometers. There are often white clouds lingering on the top of the mountain, appearing and disappearing. Mauna Kea in the north of the island is 4,205 meters above sea level and is the highest peak in Hawaii. The world's highest observatory is located on the top of this mountain. When the Mauna Loa volcano erupted in 1950, the lava flowed down the slope for more than 50 kilometers until it reached the seaside and poured into the sea. When the lava flow flows into the sea water, it causes the sea water to boil, steam billows, and dead fish float. Mauna Loa is also one of the tallest active volcanoes in the world. It erupts once every three years on average, and it reaches its current height by layers of lava flows. Mauna Loa erupted again on March 25, 1984, and the lava flowed down about 27 kilometers. Hawaiian locals believe that after being driven away by her angry sister Poseidon, Pelli, the God of Fire, came to live in the Hawaiian volcanoes. She traveled from volcano to volcano, and finally found her home in the Hermomo Crater on Kilauea Island. A safe home. The volcanic eruption we saw was said to be a manifestation of the sudden temper of the god of fire, Pelle. Geographical Features? Volcanic Island

Mauna Loa Volcano The Hawaiian Islands are volcanic islands and a famous volcanic activity area in the Pacific. Because these islands are located on the bottom crustal fault zone of the Pacific Ocean, the Hawaiian Islands are all made of earth’s crust. It was formed by the magma erupting from the fault. Until now, volcanic eruptions often occur in the craters on some islands. For example, the Kilauea volcano and Mauna Loa volcano on the Hawaiian island and the Halialakala volcano on the Maui island are modern active volcanoes that frequently erupt.

Undulating terrain

Since they are all volcanic islands, the islands in the Hawaiian Islands are all undulating mountains and hills with few plains. This also forms the beautiful and unique natural scenery of the Hawaiian Islands.

Pleasant climate - flourishing organisms

Due to the luxuriant growth of various plants and flowers, the Hawaiian Islands also have the most insects. There are more than 10,000 species of butterflies alone, some of which are unique to the archipelago. There is a kind of butterfly called "Green Human-Faced Beast Butterfly". It is a rare large butterfly in the world. Its wings are up to 10 centimeters long when spread out.

At the same time, the beaches of the Hawaiian Islands are also very beautiful. There are vast beaches and deep blue ocean. It is a good place for people to swim, surf and various water activities. Waikiki Beach is the world's most beautiful beach. on the most famous beaches. There are many coconut trees growing beside the forest avenue by the sea, which shows the tropical island style. There is also Hawaii Volcanoes National Park on the active volcano Mauna Loa on the island of Hawaii. This volcano park stretches from the crater on top of Mauna Loa to the ocean. In the Volcano Park, you can see landscapes that are difficult to see anywhere else in the world. Such as plains and lava tunnels formed by sulfur accumulation during volcanic eruptions. Sulfur-containing hot water steam can also be seen erupting from the cracked ground. In the Guilao caldera of the active volcano Mauna Loa, boiling molten magma can be seen rolling. Sometimes broken rock layers can be seen falling into the magma, and splashing torches are dozens of meters high. When the volcano's caldera activity is intense, molten magma will overflow from the volcano's crater, flow down the hillside, and flow into the Pacific Ocean dozens of kilometers away, making a roaring sound that can sometimes last for several months. Where the lava flowed, houses and trees were all engulfed by the lava. After the magma cooled, it formed a hard lava covering on the hillside, and no grass could grow on it.

Volcano formation

Below the earth's surface, the deeper the temperature, the higher the temperature. At a depth of approximately 32 kilometers above the surface, temperatures are high enough to melt most rock. Rocks expand when they melt, requiring more space. In some parts of the world, mountains are rising. The pressure beneath these rising mountains is decreasing, and a lava (also called a magma chamber) may form beneath these mountains. This material rises along the cracks caused by the uplift. When the pressure in the lava chamber is greater than the pressure in the rock cap above it, it erupts outward into a volcano.

In an eruption, hot gas, liquid, or solid material suddenly erupts. The material accumulates around the opening, forming a cone-shaped hill. A "crater" is a depression at the top of a volcanic cone that opens to the surface. Cone-shaped mountains are the product of volcanic formation. The material ejected by the volcano is mainly gas, but large amounts of volcanic rock and solid materials such as slag and ash are also ejected. In fact, volcanic rock is magma erupted by volcanoes. When the magma rises to a height close to the surface, its temperature and pressure begin to drop, physical and chemical changes occur, and the magma becomes volcanic rock. What are volcanoes made of? Below the earth's surface, the deeper it gets, the higher the temperature. At a depth of approximately 32 kilometers above the surface, temperatures are high enough to melt most rock. The formation of volcanoes involves a series of physical and chemical processes. The crust and upper mantle rocks are partially melted and separated from the parent rock under certain temperature and pressure conditions. The melt migrates upward through pores or fissures, and is gradually enriched in a certain location to form a magma pocket. With the continuous replenishment of magma, the excess pressure of magma in the magma pocket gradually increases. When the surface covering is not strong enough to prevent the magma from continuing to move upward, the magma rises toward the surface through weak zones. During the ascent, the volatile components dissolved in the magma gradually dissolve and form bubbles. When the volume fraction occupied by the bubbles exceeds 75%, the bubbles trapped in the liquid will be quickly released, resulting in an explosive eruption. After the gas is released, the viscosity of the magma drops to a very low level. At low levels, the flow becomes turbulent. If the magma has low viscosity or low volatile content, there will be only quiet overflow. A series of differences in physical and chemical changes from partial melting to eruption form a variety of volcanic activities. In an eruption, hot gas, liquid, or solid material suddenly erupts. The material accumulates around the opening, forming a cone-shaped hill. A "crater" is a depression at the top of a volcanic cone with an opening that leads to the surface. Cone-shaped mountains are the product of volcanic formation.

The Hawaiian Islands were formed by magma erupted from the crustal fractures. Until now, volcanic eruptions often occur in the craters of some islands. For example, the Kilauea volcano and Mauna Loa volcano on the Hawaiian island and the Halialakala volcano on the Maui island are modern active volcanoes that frequently erupt. Since they are all volcanic islands, the islands in the Hawaiian Islands are all undulating mountains and hills with few plains. This also forms the beautiful and unique natural scenery of the Hawaiian Islands. Although the Hawaiian Islands are located in the tropical Pacific, the temperature is not very high, nor is it too humid. The temperature ranges from 14 to 32°C throughout the year, with little change, and is very suitable for people's lives. If you live in a mountainous area, the temperature is cooler and more pleasant. The Hawaiian Islands have abundant rainfall, and many hills and mountains are covered with dense forests and grasslands, showing the beauty of the natural scenery. At the same time, the Hawaiian Islands also have their own island flower - the red hibiscus flower. On the Hawaiian islands, you can see flowers blooming all year round. Due to the abundant growth of various plants and flowers, the Hawaiian Islands also have the most insects. There are more than 10,000 species of butterflies alone, and some species are unique to the archipelago. There is a kind of butterfly called "Green Human-Faced Beast Butterfly". It is a rare large butterfly in the world. Its wings are up to 10 centimeters long when spread out. Therefore, many insect enthusiasts and researchers go to this island to study and collect butterfly specimens. The seaside of the Hawaiian Islands is also very beautiful. There are vast seaside beaches and deep blue ocean. It is a good place for people to swim, surf and various water activities. Waikiki Beach is the most famous beach in the world.
