Volcano Calbucano

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

Imagine being on an island when all of a sudden an ear-shattering boom reverberates around you. On August 27, 1883, 10:02 in the morning, Krakatoa erupted with immense force on a modern-day Indonesia island. Almost a century later, Mount Saint Helens, located in the state of Washington, erupted at 8:30 a.m., on May 18, 1980. Although Mount Saint Helens and Krakatoa had a lot of distance from each other, they were both composite volcanoes. Composite volcanoes produce a thick lava that causes a lot of damage.

Have you ever been near a volcano when it erupted? Most of us haven't, but if you're unlucky enough, you just might have. Many people think it would be cool, but it is indeed not. In fact, the people of Pompeii were very unlucky when Mount Vesuvius erupted in 79 AD. Nearly two-thousand people died. Although that eruption was very similar to the 1980 eruption of Saint Helens, it was also very different.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

The Kilauea Volcano is the youngest volcano on Hawaii’s Big Island. Because when viewed from above it seems tiny in comparison to the neighboring volcano Mauna Loa, Kilauea was originally believed to simply be a satellite of Mauna Loa instead of a distinct volcano. Research that has taken place during the last decades, however, shows that not only is Kilauea a separate volcano, but its magna-plumbing system actually goes over 60 kilometers deep into the earth. The Kilauea Volcano sits on a curved line made up of other volcanoes such as Kohala and Mauna Kea.

exciting tell all, focused on the eruptions of Nevado Del Ruiz and Galeras in Northern and

The Capulin Volcano interestingly enough, is apart of what's known as the Raton-Clayton volcanic field (RCVF), a collected scattering of other volcano's that stretch well over 7,000 square miles. Located in Northeastern New Mexico, the Capulin lies dormante, although some believe extinct, since it's last volcanic activity more than 60,000 years ago. Capulin underwent a rather large eruption that formed its current 1000ft cinder cone shape, which gave way to "a number of small lava flows and cinder eruptions [that] paved over the mound, steepening it's slopes"(NASA, 2016). The base was inital made from the hot ash, cinder, and rock debris of the eruption, and the lava flows themselves were "basalt, deriving from the melting of the mantle" (Sayre and Ort, 2011). Due to

Another well-known geological phenomenon in the United States is Yellowstone Park. Yellowstone is an extraordinary example of a caldera which is defined as “a volcanic crater that has a diameter many times that of the vent and is formed by collapse of the central part of a volcano or by explosions of extraordinary violence”(USGS). Since Yellowstone is a caldera, it means that there had been previous volcanic eruptions in this area and in this case two eruptions. The first explosion happened over 2,000,000 years ago because the composition of the magma contained vast traces of explosive matter that caused the eruption (USGS). The second incident happened around

On April 30, 2015, a volcano in Chile called Calbuco erupted for the third time in eight days. Calbuco is located near the town of Puerto Montt. One witness, Gregorio Billikopf, said that this eruption was not as dramatic as the previous eruptions that occurred on April 22 and 23. Others have also observed that the most recent eruption of Calbuco was smaller than the earlier eruptions. About 1,500 people were evacuated is what Deputy Interior Minister Mahmud Aleuy said. Due to the steady decrease of seismic activity, the agency of geology in Chile warned of the chance of a third eruption. Authorities in Chile have been keeping people away from a 12 mile exclusion zone surrounding the volcano. In the previous week 4,400 residents were evacuated with assistance from police and military. Ash from the second eruption spread all the way to Argentina. Not all evacuations were for humans though, some included animals. In some places, the volcanic debris has reached up to almost 2 feet high. New information claims that ash in the air could reach an altitude of 12,000 feet. Last week, the town of Ensenada was blanketed in ash and the cities of Puerto Montt and Puerto Varas were under a red alert.

The May 18th, 1980 eruption was quite interesting. The eruption killed a total of 57 people. Everyone that was killed was between the ages of 9 and 83. Most of the people that died inhaled ash, and the ash got into their lungs, which is probably not good. There was a lot of ash that came out of MSH that day. Central and Eastern Washington was covered in 3 to 5 inches of gritty fine ash. Not including the estimated 540 million tons of ash that came out of MSH in the form of a mushroom cloud that reached 12+ miles (≈14 km) into the air. The ash also circled the Earth for 15 days after the

Seagulls flying in the sky on top of the golden sandy beach. Palm trees stand tall and strong. This is Hawaii, home to the great Mauna Loa. Mauna Loa is the largest volcano on earth. It is also one of the five volcanoes that created the beautiful island known as Hawaii. This shield volcano is one of the most active volcanoes in the world! The name Mauna Loa means “Long Mountain” in Hawaiian. Whenever this giant volcano erupts, it's usually extremely hazardous, threatening its surroundings. Mauna Loa may be very large and dangerous, but it is quite fascinating!

The largest eruption that ever happen was the Kulshan caldera. More than 50 km3 of rhyodacite magma exploded from a shallow magma storage region and filled the caldera and surrounding valleys with ignimbrite. That amount of material

The Kilauea Volcano is the youngest and most active Hawaiian shield volcano. This volcano is located on Hawaii’s Big Island. The volcano is part of the Hawaii Volcanoes National Park. Kilauea is 300,000 to 600,000 years old. The native people from the Polynesian Islands discovered Kilauea. The other four volcanoes of Hawaii are Kohala, Mauna Loa, and Mauna Kea.

Erupting steadily since March 2008, the summit crater, Halemaumau continues to send plumes of sulfur dioxide and steam clouds. In the east rift zone of Kilauea is Pu’u O’o, a volcanic vent that is considered active. You can safely access this area by helicopter because it is too far from roads to drive however if you don’t mind the mile walk, you can hike in on a marked pathway to view the lava flows. The world’s largest active shield volcano, Mauna Loa, is also located on the Island of Hawaii. Mauna Loa’s last eruption was March 24 through April 15, 1984, and has been heavily monitored since 1912 because of its immediate threat to population centers.

Considering that El Chichon had been non-active for over 600 years, many disregarded the minor eruptions that were occurring frequently prior to 1982. The first of the three major plinian eruptions was on 28th March that lasted only a few hours with an intensity four times greater than that of the 1980 Mt St Helens disaster, however many did not flee or know what was yet to come. All seemed to have settled down and those that chose to flee after the initial eruption, returned. But it wasn’t until April 3rd that the next eruption began. A Plinian eruptions reached an altitude of over 24km, which left very little time to process these sudden bursts before the final instalment quickly arrived. The 3rd of April event was the last major eruption of El Chichon and also left the most impact. A pyroclastic flow began to emerge that ran over 8km
