    The great Crater Lake in Oregon was once a stratovolcano named Mount Mazama. Mount Mazama had a very catastrophic pyroclastic eruption that produce about 12 cubic miles of magma. The Mount Mazama volcano has been recorded as one of the largest volcano eruption that has taken place in the last 10,000 years. The Mount Mazama volcano was one of the major volcanoes at the Cascade Range. The range of Mount Mazama’s summit was roughly between 11,000 and 12,000 prior to its climatic eruption. The climatic eruption took place in two stages. The first stage took place at a solitary vent that caused a Plinian eruption. There was so much magma that erupted that the vent widened and the eruption collapsed creating pyroclastic flows that deposited welded…

    The explosion caused an earthquake and tsunami because of the pyroclastic flows and collapse of the caldera. These other devastations caused flooding and disaster on several of the other Indonesian islands. The death toll was sky high and as well as the largest death count recorded by a volcano, the ash filled the skies and killed all the vegetation and eatable crops resulting in more death by disease and starvation. The death toll reached at least 71000; 11000- 12000 were killed directly by the…

    Hawaii has recorder statistics on the Kilauea volcano and has been recorder the number of eruption. It was recorded that “fifty-seven eruptions and intrusions occurred at Kilauea between 1960 and 1983, after which the volcano has been in a state of virtually continuous eruption (Bell, Kilburn, 2012).” These earthquakes were mostly predicted by earthquakes, but this is not necessary the main reason for an eruption. When these eruptions occurred most of the magma was transported through rift…

    A single eruption at Yellowstone National Park could kill as many as 90,000 people. Though many people think it will not erupt, there is a supervolcano underneath yellowstone. Yellowstone is the first national park that is home to a super volcano. There is lots of wildlife like grizzly bears, wolves, elk, and herds of bison. These make Yellowstone a popular tourist attraction. If this supervolcano erupts it could destroy the wildlife and have a giant impact on the united states. Scientist more…

    On August 26, 1883, a catastrophic natural disaster happened that affected the lives of people near and far. The volcano, Krakatoa, erupted leaving a great deal of devastation in its wake. Krakatoa is a volcanic island located in the Sunda Strait along the Indonesian Island Arc. The island along with two others were remains of an earlier eruption from two hundred years before. Krakatoa Island had three large hill-like or mountain shaped volcanic cones named Rakata, Danan, and Perboewatan. Before…

    Noraly Caldera Journal entry # 2 Memories Perhaps my earliest memories of being read to began when I was 4 years old. My grandfather used to read the newspaper to us every morning during breakfast time, unless he wasn’t feeling well. He would often say the newspaper was the best way to keep us himself and us informed of what’s going on throughout the world. Although I was fairly young these are one of fewest memories that could recall vividly and I hold on…

    Erta- Ale, is today the longest continually erupting volcano on the planet. It is pretty much a lake of lava that has been molten for over 100 years. These same volcanic forces are what created Ethiopia’s highlands. Seventy million years ago, Ethiopia’s land was just flat and deep terrestrial land. It wasn’t until molten lava rose from the Earth’s core and crated a huge dome of rock 500 miles wide: the roof of Africa. The summit is about three miles high and are home to some very…

    Yellowtone Supervolcano

    The magma melts the nearby rock to form more extremely thick magma. The magma is so viscous that volcanic gasses that normally trigger an eruption cannot pass, so a massive amount of pressure begins to build up. This continues for hundreds of thousands of years until an eruption occurs, which blasts away a huge amount of ground, forming a new caldera. The same principle would happen at Yellowstone if it were to erupted, too much pressure and the chamber…

    Most people have heard of Yellowstone National Park but not everyone knows how strange yet spectacular the caldera actually is. Yellowstone is a supervolcano and the park sits on top of a massive crater called a caldera. According to a NOVA documentary, the caldera is large enough to hold the city of LA and the magma chamber encompasses half of the park above it and extends almost 5 miles deep (Adah, 2016). This makes Yellowstone’s magma chamber the largest known on Earth. Since Yellowstone is a…

The super volcano is a hot spot for it to erupt from molten rock,the super volcano will erupt for more than 1,000 cubic kilometers,and 240 cubic miles of magma. There will never be another catastrophic eruption at…
