Mauna Loa
Mauna Loa, located in Hawaii, is the largest active volcano is the world. Mauna Loa is a shield volcano, comparable to many of Earth’s other large volcanoes. According to Caitlin Kelly with USA Today, “Shield volcanoes are formed by many lava flows that build up and create long, gentle slopes, rather than a steep-sided mountain.” Shield volcanoes emit low viscosity lava, which means the lava flows easily. This creates an enormous landform with a wide base. Mauna Loa makes up 50% of the Big Island of Hawaii, with an area of 2,035 square miles. In Hawaiian, Mauna Loa means “Long Mountain.” Data from the Hawaiian Volcano Observatory shows that Mauna Loa rises approximately 13,680 feet above sea level, and 16,400 feet below. Furthermore,

This Hawaii Volcano has erupted 33 times since 1843. Its most recent eruption was in 1984. The 1984 eruption lasted from March 25 to April 15. Before the eruption, increasing seismic activity could be felt on the island. During the eruption, many lava flows were produced, but fortunately, no lava reached the city of Hilo (“1984 Eruption”). There is a high likelihood that Mauna Loa will erupt again someday, so the volcano is closely monitored.
Mauna Loa’s summit caldera, or crater, is named Moku`aweoweo and “has an area of nearly 6 square miles and a depth of 600 feet (“Mauna Loa”). Moku`aweoweo is estimated to have collapsed around 600-750 years ago.
Kelly describes the climate on the Big Island. The immense mass of Mauna Loa has an effect on the island’s climate. The volcano prevents some heavy winds from reaching the west side of the island, resulting in the west side being warmer and dryer. The eastern side receives substantial rainfall allowing vegetation and greenery to flourish. The summit of the volcano is sometimes covered in snow, due to the high altitude and cold temperatures (Information on Mauna
With no prolonged periods of inactivity the volcano has continuously built up on itself. The last major eruption took place in 1790 and killed many people and animals, but numbers are unknown4. Starting in 1983 there was a chain of several eruptions that started and have yet to stop pushing lava through a lava tube till it reaches the Pacific Ocean. Over a span of twenty year the flow has
La Mauricie national park is famous for all its beautiful lakes and forest and obviously its different variety of wildlife. The many hills that sprout from la Mauricie national park are speckled with magnificent lakes. The park is located in the Canadian Shield, where the formations are a billion years old, but it is still the youngest area. There are a variety of tree species, more than 400 species of plants, 85 mosses, and close to 70 lichens species. A couple of rare plants are monitored by the park. Broad leaf trees are usually found in the north of the park and boreal trees further down south. Trees such as the the sugar maple, the yellow birch, the balsam fir, the pine, christmas trees, and the spruce are spread around the park densely. Animals are also another attraction in the park for visitors. There is a lot of species of mammals, even more species of birds, around a dozen species of reptiles and almost 30 fish species. There are some white tailed deer, long tailed
Kilauea is one of the most active volcanoes on Earth, and it is the youngest. Kilauea stands just under 4,200 feet tall above sea level at its highest point.
The basic theory of plate tectonics says that all volcanic activity should occur between lithosphere plates (Physical Geology). However, the Hawaiian Islands bend this rule by being located directly in the middle of the Pacific plate. The Hawaiian volcanoes are known as intraplate volcanoes. This may not seem possible because it disrupts the rule of plate tectonics, but there’s the exception of a hot spot. T. Wilson suggested that the Pacific plate moved in the northwestward direction over a melting spot deep within the mantle, and this hot spot remained relatively stationary and supplied magma to the moving Pacific plate to form the Hawaiian Island chain (Volcanoes in the Sea). In order to prove this suggestion, the structure of the Hawaiian Islands must be in line with a hot spot origin. This will be
Mauna Kea is currently the tallest mountain in the Hawaiian Chain. 4,205 meters above sea level, Mauna Kea is located on the island of Hawaii. It is the second largest surface that comprises of the five volcanoes on Mauna Kea. With Mauna Kea being the largest Mountain in the Hawaiian chain, it is a popular location to look into the galaxies, to find the origin of life.
Mauna Loa is considered a “shield volcano” meaning its eruption are as violent as they could be, however because of its enormous size, it will still be a reckoning, like journalist James Cave says, “Of the five active volcanoes in Hawaii, only the Kilauea and Loihi volcanoes have been quietly erupting consistently for decades. But Mauna Loa is seen as the big threat there. What Kilauea erupts in one day, Mauna Loa has erupted in 20 minutes, as it did in 1984. It came way too close to destroying Hilo, where more than 35,000 people lived at the
The Hawaiian islands cover 6,459 square miles and the land area is 6,423 square miles. The highest poin in Hawaii is Mauna Kea which is 13,796 feet into the sky. The lowest poin in Hawaii is at Pacific Ocean edge. Mauna Loa is the largest volcanic mountain in the world measures 13,679 ft in volume. The Mean Elevation is 3,03 feet above sea level. The highest temperature is 100 degree Fahrenheit which recored on April 27, 1931 at Pahala. The lowest temperature in Hawaii is 12 degree Fahrenheit recored on May 17, 1979.
Teens all around Hawai’i are very very passionate about Mauna Kea because it has long lasting history as the biggest mountain and is sacerd to hawaiian’s and they want to protect it from change. Mauna Kea is a dormant volcano on the island of Hawai’i, it has the highest point in the State of Hawai’i, as well as being the tallest mountain in the world when measured from base to summit. I am a 15 year old Sophomore at Konawaena High School.
A region is an area that has common features. Las Vegas is in the State of Nevada and the North America continent. Nevada can be divided into 4 land regions: the Columbia Plateau, the Sierra Nevada, The Mojave desert, and the Basin and Range region. It is situated in a mountainous region that has massive semiarid grasslands and alkali deserts. It is in the Western, Mountain West, and Southwestern districts of the U.S. The large cities located in the basins are Reno and Carson. However, Elko, Elko, Fallon, and some other cities are located there. The Mojave Desert’s region includes Vegas, Henderson, and Boulder City. Its region type is a state.
The blast was preceded by two months of intense activity that included over 10,000 earthquakes, hundreds of small phreatic (steam blasts) , explosions and the north side bulge. A magnitude 5.1 earthquake below the volcano at 8:32 am started the eruption. MSH is still a potentially dangerous and active volcano even though it has been quiet since 1995. In the last 515 years there have been four major eruptions and dozens of lesser eruptions. Two of the eruptions were only two years apart. In 1480, the eruption was about five times larger than the one in May 1980. There have been even larger eruptions during MSH' 50,000 year lifetime. After the May 18, 1980 eruption, there have been five smaller explosive eruptions over a five month period. Since then, there have been 16 dome building eruptions through October 1986 when the new dome in the crater was formed. As the mountain was torn open, the pressure in inside was suddenly relieved. The rock shattered inside the mountain was exploded out the top at speeds over 200 miles per hour. The blast was so strong that it leveled whole forest of fir trees. Geologist call this a "stone wind" since the winds carried the rocks form the blast with them. The rocks gave the winds extra force that let them flatten the trees. 150 square miles of land was leveled. The edges of this area also lost their forested areas from the heat of the blast and the fires it caused. The original blast of the
A particular vulcanologist, Frank Trusdell who is working for the USGS Hawaiian Volcano Obsevatory (HVO), have been studying the historic eruptions of Mauna Loa for the past 3 decades. Trusdell mentioned that Mauna Loa erupt at a long term average of once every 6 years. Currently, there are not much activity by comparing the seismic activity in 1980-1984 to 2011-2014. When a volcanic eruption is imminent, the HVO will alert the Hawaiian emergency management agency and civil defense officials in full emergency mode. Necessary evacuations will be organised for residence and so as broadcasting live alerts through TVs and radio stations. Also, status, reports and HVO websites of the volcano’s activity will also be constantly updated to make sure
Mauna Kea is a dormant volcano on the island of Hawaii. It has an altitude of 13,976 feet above sea level, the highest of any mountain in Hawaii, and is the tallest mountain in the world when measured from the base below sea level. Roughly translating to “Sky Father Mountain” in Hawaiian, Mauna Kea culturally represents the “Realm of the Gods” in Hawaiian lore. It is a sacred ground considered to be where Earth and the gods are connected, the burial ground of many Hawaiian ancestors, and is overall of extreme significance in Hawaiian culture.
Dr. Richard Waitt inform us that the eruption on May 18, 1980 surprise scientists because they had a lot of data that they collected and that data didn’t indicated that an eruption was going to come on that day. When it blast in May 18, 1980, it destroyed everything in their path. For example, a total of 57 people were killed, thousands of deer, elk, bears, and other wildlife were killed, and the eruption had cut open a 2,000-foot-wide crater in the top. The landscape was unrecognizable by geologist who had spent about two months before the explosion on May 18 working up the volcano every day. It is interesting to know that discolored rock in the valley and in the crater wall were evidence that the mountain was decaying before the eruption.
People are afraid that this volcano will explode and are scared that something bad will happen. People are moving out of their house to a safe place to live and were forcedd to evacuate about 2,000 residents. Some people choose to move out to a safer place and away from the dangerous area. Residents are involved in this tragic event, stay in not an option for anyone dangerous gases are released and can kill anyone human inhale this dangerous gases. The event is about a volcano that is about to explode from so much pressure being built up. This event is happening in Hawaii were people want to move out. It's happening in May 4 at 11:40 a.m. The cause of this event is happening because pieces of rock are falling off to the volcano and that is making pressure built up and has to escape some we're including magma is falling below sea level. This is one of the most active volcano in the world. It will continue for 100 years no surprises this is happening because it has happened over millions of years.
The Hawaiian volcano is a shield volcano; they are the oldest continental regions of earth. They may even be the remains of ancient shield volcanoes. A shield volcano is tall and broad with flat, rounded shape. The Hawaiian volcanoes are built by countless outpourings of lava that advance great distances from a central summit vent or a group of vents. Extensive study of the Hawaiian Islands revealed that they are constructed of a myriad of thin basaltic lava flows averaging a few meters thick intermixed with relatively minor amounts of pyroclastic ejected material. During eruptions these outpourings help keep these volcanoes safe. When these volcanoes erupt lava fountains out form the volcano and is hot liquid lava is thrown into the air but usually not very high. The lava normally flows easily, and does not explode. These volcanoes also only explode if water some how gets into the vent. Mount St. Helens is composite volcano, which are also known as strato- volcanoes. They are tall, symmetrically shaped, with steep sides, sometimes rising 10,000 feet high. They are built of alternating layers of lava flows, volcanic ash, and cinders. The large and generally cone-shaped volcanoes form along plate boundaries called subduction zones where one of the earths plates melts as it falls back into the earth`s mantle. The eruptions are called explosive, and effusive, because vast amounts of gasses are thrown into the atmosphere, and the lava explodes and is vicious.
