Mt. Fuji Research Paper

This chamber gave birth to the cataclysmic eruption of 760,000 years ago, and is connected to the magma which erupted from the chain of rhyolite domes that stretch up to the northwest. Eruptions crept sequentially along this line, beginning with the Bishop Tuff eruption and most recently displaying activity in the middle of Mono Lake at the island Negit. This most recent volcanism of the Inyo-Mono crater eruptions occurred as late as 1850 A.D (Bailey, et. al., 1989).

Mount St. Helens Location: Washington, United States Latitude: 46.20 N Longitude: 122.18 W height: 2,549 meters or 8,364 feet - 9,677 feet before May 18, 1980 Type: Stratovolcano Number of eruptions in past 200 years: 2-3 Latest Eruptions: Between 1660-1700, around 1800-1802, 1831, 1835, 1842-1844, 1847-1854, 1857, 1980-? Present thermal activity: strong steaming Nickname: Mount Fuji of the West Remarks: continuous intermittent activity since 1980 with occasional eruptions of steam and ash; occasional pyroclastic flows; intermittent dome forming. MSH is considered a young volcano that developed over the last 40,000 years and is one of the most active volcanoes in the Cascade Range. Geologists predicted that the

Mt. St. Helens erupted on May 18, 1980 and it is said to be the most disastrous volcanic eruption in United States history. There had been months of build up beneath the surface along with a massive bulge growth on the side of the mountain. It began when an earthquake struck beneath the north face of Mt. St. Helens, which set off the biggest landslide to ever happen in the US. Seconds later there was an explosion of the north side of the volcano generating a huge cloud followed by lightning. The large landslide was followed by several lahars (mud flow) and pyroclastic flows (hot gas and volcanic matter).

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.

Mount St. Helens, located in southwestern Washington about 50 miles northeast of Portland, Oregon is one of several lofty volcanic peaks that dominate the Cascade Range in the Pacific Northwest. Mount St. Helens sits on a plate boundary. It’s the plate boundary between Juan de Fuca and the North American plates. The spot in which it sits happens to be in the ring of fire, a string of volcanos that are more volatile since they sit between the two plates. Although the mountain has been called the most beautiful in the Cascade Range and has been compared to Mt. Fujiyama, everything changed on May 18, 1980, when the quiet Mt. St. Helens decided to become an active volcano and cause the worst natural disaster in the history of the U.S. The eruption

Mount Kilauea, also known as the angry goddess Pele, is an active shield volcano located in the Hawai’ian Islands. Today she is still roaring day and night; flowing lava onto the island and into the vast sea. Mount Kilauea is located on the Pacific Plate boundary which is a convergent plate boundary. A convergent plate boundary is when one plate boundary moves under another. This can cause volcanoes and earthquakes and this was the boundary that rose Mount Kilauea from the Earth. The current stage of Mount Kilauea is still at the eruption stage and still currently erupts lava into the sea. It is also said that the volcano is still on aviation color code: orange.

The most recent disaster caused by Mt Fuji was the March 5th, 1966 BOAC flight 911; this horrible atrocity caused by strong turbulence formed by lee waves at the bottom of the mountain, leaving 123 people dead. The Jogan eruption of 864 CE lasted for 10 days killing thousands and destroying numerous homes. The Hoei eruption of 1707 also the last eruption of Mt Fuji, was caused by two 8 point earthquakes on the Richter scale igniting the complete empty of the volcano's magma chamber leading to the spread of ash from Tokyo to Edo (231 miles). Mt Fuji also has many positive effects on humanity such as the falling ash fertilizing the soil around the volcano and depositing various essential raw materials needed for the manufacturing of electronics. Mt Fuji has also made many appearances in Japanese text and currency, not to mention their flag represents the sun coming over the

Mount Vesuvius developed inside the caldera of an older volcano. This volcano was known as Monte Somma. Monte Somma became active around 400,000 years ago. Only the northern side of Monte Somma is left, creating a wall-like ridge around the northern edge of Mount Vesuvius. This feature can be observed today at the site of Mount Vesuvius. The development of Vesuvius produced a volcanic complex consisting of the two volcanoes. (De Boer and Sanders, 2002)

This explosion during March caused two very large craters to open which then turned into one gigantic crater and at the same time a huge bulge on the northern region of the volcano appeared, this grew about six feet every day. Geologists researched the site of the bulge, measured the earthquakes, collected ash and sampled the gases that were released during this period and eventually the bulge grew to three-hundred feet wide and was over a mile in length.

According to Zeilinga de Boer & Sanders (2002) the north side of the volcano slid down in 3 blocks. The blocks then broke up and formed into an avalanche that raced down the volcano at more than 200 km/h. The avalanche of rock, glacial ice, snow and debris relieved pressure on the

The eruption also re-awakened the people’s worry about the other volcano in Japan. France Nihon University Joint research articles and worked in July noted that Fuji has great danger of the outbreak, after the 2011 earthquake in Japan (). Volcano experts point out that the last time Mount Fuji erupted was in 1707, just 49 days after the massive 8.7 magnitude Hoei earthquake（Telegraph）. A very strong earthquake like that seen on 11 March 2011 (which caused a catastrophic tsunami) can heighten the risk of volcanic eruptions in the region due to an accumulation of magma,” he said in 2012(Telegraph). The impact would be the number of visitors fell within the volcano tourist areas, especially tourist area of Mount Fuji. On the

Over the past 2.1 million years, three large eruptions with widespread effects have occurred in the Yellowstone Plateau Volcanic Field (YPVF) (Hurwitz & Lowenstern, 2014). The first of these was 2.059 ± 0.004 Ma (Lanphere et al., 2002), and produced the >2450 km3 Huckleberry Ridge Tuff. The second was at 1.285 ± 0.004 Ma (Lanphere et al., 2002), producing the >280 km3 Mesa Falls Tuff and the Henrys Fork caldera. The most recent of the three occurred 0.639 ± 0.002

Mount vesuvius besides being a hundred of thousands of ear old volcano is also a somma stratovolcano. It is about 9 kilometers east of Naples and is a short distance from the shore. It is one of many volcanoes that formed from the Campanian volcanic arc. Its last eruption was in the year 1944. In the last 17,000 years it has had eight major eruptions. The 79 A.D is the most well known eruption out of the

Throughout the first eight weeks of Physical Geology I, I have learned more about the Earth, how it works, and natural disasters than I have in my entire educational career. We have analyzed everything from the different types of rocks to several different natural disasters such as volcanoes and earthquakes. However, one thing in particular caught my attention and fascinated me through its sheer power and destruction. Volcanoes are intriguing, and they have the force and destructiveness to wipe out an entire population.

Mt. Vesuvius is a member of a line of volcanos established on top of a subduction zone, called the Campanian volcanic arc. Mt. Vesuvius is an andesite, which is 53% silica, can create explosive eruptions on many ratios. The arc is created by merging Eurasian and African plates, reaching the Italian peninsula, like Mount Ertha which was formed the same way. This makes Mt. Vesuvius’s dicey eruptions, incredibly more dangerous
