Kilauea is a volcano in the Hawaiian Islands it is one of the five shield volcanoes in the Hawaiian language Kilauea means spewing or spreading. Mt St. Helens is an active stratovolcano in Washington it is named after British diplomat lord st Helens.…
Of the volcanoes that are located in the United States there are two which are world renowned for their activity and their power to change the region surrounding them. The two volcanoes would be Mount Saint Helens and Mount Kilauea. In order to get a better understanding of these volcanoes we will be comparing and contrasting them as well as talking about how they were formed and when they last had an eruption.…
Cinder cone volcanoes are just one of many types of volcanoes. A cinder cone, or scoria cone, is a steep conical hill made in large part of pyroclastic fragments. They are the simplest type of volcano and tend to be small and hill like. They are built…
Shield volcanoes form when the products of eruption have low viscosity and are weak, so they do not pile up but spread. They are broad, gentle does that resemble a solder’s shield. Cinder cones are cone shaped piles of basaltic lapilli and blocks. Strato-volcanoes are large; cone shaped and is made of interleaved layers of lava, tephra and volcaniclatic debris. The prefix of its name emphasizes that they can grow to be kilometers high.…
Mauna Kea is part of the network of volcanos above the Hawaiian hotspot. The tectonic plate that has the Hawaiian islands is slowly moving above the hotspot, and it recently carried Mauna Kea away from the hotspot. Scientists believe that Mauna Kea is now dormant; it last erupted about 4,500 years ago. Although, researchers do think it’s going to erupt again, the time between eruptions is measured in hundreds of years. The most active volcano on the island, Kilauea, erupts every few years.…
Other kinds of Volcanos include a shield volcano that is typically large and has slow flowing liquid lava and a composite volcano. Composit volcanoes are steep and large and have layers from past eruptions that are made of lava.…
1. The name of my volcano is Mount St. Helens, it is located in Southern Washington State. Mount St. Helens is part of the ring of fire, a circle of active volcanoes that surrounds the Pacific Ocean.It is one of the most beautiful mountains in the Cascade Range, because It is a dormant stratovolcano many people will visit to play in the snow at it’s basen.…
A volcano is a mountain with a vent at the top where magma and gasses…
Mt. Nyiragongo is a stratovolcano, a composite-cone volcano. It is on the African plate, where it is splitting in the middle at a divergent plate boundary. The type of lava in the enormous lava lake is melilite nephelinite, mafic lava, with low viscosity due to the low silica content. The magma is olivine melilititic formed by small-fraction partial melting at the base of the lithosphere. The rock that comes from Mt. Nyiragongo is melilite nephelinite. The volcano is 2 miles high (or 3,470 meters), and is at a summit elevation of 11,365 feet. The sides are sloped up to 50 degrees near the top, and the main crater (summit) is 1.3 miles wide (or 2 km). Mt. Nyiragongo is an immense volcano, and has an unusual composition in the magma, lava, and dried rock.…
Covering over 85% of Hawaii, Mauna Loa meaning long mountain, is the earth's largest volcano. Located on the main island of Hawaii, Mauna Loa pushes 12 million cubic meters of lava into Hawaii each day. It rises over 4 km above sea level. But, below the sea, it drops another 5km to the sea floor which is then indented another 8km under the weight of this giant land form. This means the total height of this volcano is a whooping 17km high from the base of the volcano to the crest. It is amid the earth's most currently active volcanos with its most recent eruption in 1984 being both extremely beautiful and destructive. It has been documented erupting 33 times between 1843 and 1984 at 5-6 year intervals and scientists currently expect an eruption…
Mauna Kea on the island of Hawaii is known to be the tallest volcano in the world. Mauna Kea has a elevation of about 13,796 ft. but the base of the volcano is close to 19,685 ft. below sea level making. Mauna Kea is over 33,000 ft. tall making it the tallest mountain on earth. Along with being the world's tallest volcano it is also home of the world's largest astronomical observatory.…
They use a seismograph to record seismic waves and use the S-P time method to figure out the epicenter.…
Since Mauna Loa is part of Hawaii, it is formed by a hot spot (“Hawaii: Geology”, n.d.). The Pacific Plate, known as a hot spot, is present in Kilauea, Loihi seamount, and Mauna Loa. The plate enabled the formation of Mauna Loa, thus produces consecutive eruptions. Although eruptions can be hazardous, the ones in Hawaii are considerably not destructive (“Hawaii: Geology”, n.d.). Mauna Loa and the near Kiluaea (“Hawaii: Geology”, n.d.) are the only relatively active volcanoes in Hawaii. One of the first eruptions of Mauna Loa occurred about 700,000 to 1,000,000 years ago (“Mauna Loa Earth’s”, n.d.). It is estimated every six years the Mauna Loa erupts lava flows (“Frequently Asked”, n.d.) An initial documented account of an eruption was in 1780 (“Eruption History”, n.d.). The volcano has reportedly erupted thirty-three times since 1843, making it one of the most active volcanoes on the…
The two active volcanoes are Kilauea and Mauna Loa. The 4,000 foot high Kilauea is the one everyone wants to see. The Kilauea Visitor Center will supply you with current information on trails and where you might see lava flow. Plan to spend the better part of the day here because you're looking at a 3 hour hike or an 11 mile drive along Crater Rim Drive. The scenery is breathtaking as you pass by the Kilauea caldera and through a lush tropical rain forest. This is one place you'll be talking about for years even if you didn't see the lava flowing while you were…
Have you ever heard of Mauna Loa? Rising gradually to more than 4 km above sea level, Mauna Loa is the largest volcano on our planet. Its long submarine flanks descend to the sea floor an additional 5 km, and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km. This makes the volcano's summit about 17 km (56,000 ft) above its base! The enormous volcano covers half of the Island of Hawaii and by itself amounts to about 85 percent of all the other Hawaiian Islands combined. Now let's get to finding out about lava.…
