According to the Smithsonian Institute, about 160 volcanoes erupt each decade. The United States isn't usually considered a volcanic country, but we have our share. The following posts will provide some information about the volcanic landscape of America, highlighting some of our active, dormant, and extinct volcanoes. You may be surprised to see where some of them are!
Students: Please provide the name and location of your volcano, as well as its status and eruption history, in a few well-written and proofread sentences. Feel free to add a picture as well.
The Volcano I chose was Kilauea which is located in Hawaii. This volcano has continuously since 1983 so it's status is still active. It Is a shield volcano so it has effusive eruptions so it's not very dangerous and gives a chance for people like scientists to do research on them. It is also the most active volcano in the world. It's elevation of the summit is 4091 ft above sea level. Kilahuea's caldera is 165m deep and they say that this volcano is the home to the goddess Pele.
ReplyDeleteMy volcano is called Mammoth Mountain and is located near a town called Mammoth Lakes in California. It formed from continuous series of eruptions that started 110,000 years ago and it is still active. It's last major eruption was about 700 years ago and erupts every 5,000 years. Mammoth Mountain is composed of rhyolite so its lava is highly explosive.
ReplyDeleteMauna Kea is a volcano on the island of Hawaii. The name Mauna Kea means "White Mountain". Mauna Kea is a dormant volcano with its seasonal snow peaks. It last erupted 4,600 years ago in seven different vents. Mauna Kea is expected to erupt again but when it does there will be enough warning to evacuate everyone. The Mauna Kea is about 1 million years old and is a shield volcano.
ReplyDeleteThe volcano I chose is called Mount Hood. It is located in Oregon and is the tallest mountain in that state. The elevation of Mt. Hood is 11,250 feet above sea level. The last time this volcano erupted was in 1866. Since 1950, there have been several earthquake swarms each year at Mount Hood, mostly seen in July 1980 and June 2002. Seismic activity is monitored by the USGS Cascades Volcano Observatory located in Vancouver, Washington, which issues weekly updates. The most recent evidence of volcanic activity at Mount Hood consists of fumaroles near Crater Rock and hot springs on the flanks of the volcano. because of this evidence it is a dormant volcano. Mt. Hood has snow on the top of the mountain and is a composite volcano. It had a plinion eruption, which had ash blast, pyroclastic flow, laher and ash mixed with snow.
ReplyDeleteThe volcano I chose is called Mt. Baker. Mt. Baker is a Stratovolcano. It is located in North Cascades of Washington State, United States. The height of my volcano is 3,285 Meters (10,778 Feet). It is currently listed as an active volcano. Its Eruption history is: 1820, 1843, 1846, 1853-54, 1858, 1859-60, 1863, and 1870. The University of Washington Geophysics Program currently monitors the sematic activity.
ReplyDeletethe valcano I choose was Mt. Cleveland. Mt. Cleveland is in Alaska and is showing signs of errupting soon. The first time it errupted was in 1944 and the last time was in 2010. It eerupted well over a dozen times before that. This valcano is about 984 feet hight.
ReplyDeleteThe volcano I chose was Mt. Rainer. Mt. Rainer is located in the state of Washington, and is 54 miles Southeast of Seattle. It is a Stratovolcano and is currently active. The most recent recorded eruption was between 1820 and 1854. There is also reports of seismic activity, in which, there are about 5 earthquakes monthly. It is known as one of the dangerous volcanoes in the world. An eruption can cause catastrophic damage because of the ice glacier located in the summit. If an eruption plenty of homes would be destroyed, and the lives of many would be gone.
ReplyDeleteThe name of my volcano is called Mount St. Helens. It is located in Shamania County, Washington. This volcano is known for its catastrophic eruption on May 18, 1980. It was the deadliest and most economically destructive volcanic event in the histoy of the United States. Mount St. Helens is about 40,000 years old and it is still active today.
ReplyDeleteThe Craters of the Moon is a dormant volcano located in the Snake river plain in central Idaho. Lava flows that form the lava field range in age from 15,000 to just 2,000 years old. While they are currently dormant, they have gone through eight different eruptive periods and are predicted to erupt again within the next thousand years.
ReplyDelete(Lucas Perez) My volcano is called Mt. Augustine. It is located in the Augustin Ilands on the Alaska peninsula, Mt. Augustine is a large lava dome complex. The largest recored erution from Mt. Augustin was in 1883, it caused much distruction, the volcano is still active to this day.
ReplyDeleteCraters of the Moon:
ReplyDeleteIt is a dormant volcano located in the North Western part of the eastern Snake River Plain in central Idaho. The volcanic field contains at least 60 lava flows, 25 cinder cones, and 8 eruptive fissure systems.Craters of the Moon formed in 8 eruptive periods lasting several hundred years each. The first eruptions began 15,000 years ago, and the most recent eruptions ended 2100 years ago. It is predicted to erupt again within the next 1000 years.
Mt.St.Helens is located in Skamania County, Washington. It's an active strato volcano which last erupted July 10,2008. It is notoriously known for the eruption on May 18,1980 at 8:32 A.M which is a Richter scale value 5.1. This eruption killed 57 people, destroyed 250 homes, 47 bridges, 15 miles of railway, and 185 miles of highway.
ReplyDeleteMt.Shasta is located in Vicinity, California. It is an dormant volcano meaning it is inactive but not extinct. Mt.Shasta is also a composite and a stratovolcano. The main feature that shows its composite is because of all of the snow on the top of the volcano. The last time Mt.Shasta erupted was 1786 it was said to have been its largest eruption. The only dangers we could suffer from it now are blast of volcanic rock, landslides, debris flows, and magma seeping out of any area of the volcano.
ReplyDeleteJackson Volcano is an extinct volcano located 2900 feet beneath the city of Jackson, Mississippi, under the Mississippi Coliseum. The volcano was discovered in 1819. Jackson Volcano is believed to have been extinct for at least 65 million years.
