Volcanoes Volcanoes are magnificent yet dangerous structures created by the forces of nature when Earth’s tectonic plates diverge and collide against each other letting the Earth vent out pent up gases, magma, rock, and ash. There are three types of volcanoes called Shield, Stratovolcanoes, and Cinder cones. Volcanoes are further labeled as active, dormant, or extinct depending on recent activity. The magma underneath the Earth’s mantle is responsible for the explosion and creation of volcanoes…
1 Introduction Since the eruption in 1980, the area around Mount St. Helens has rebounded in ways that were somewhat unexpected, with recovery coming not only from the surrounding area, but from within the barren expanse that remained after the eruption. While not the first eruption overall, this eruption was the first to occur on the U.S mainland in a time when modern scientific monitoring could track the events associated with it. Smaller earthquakes in March of 1980 eventually led to the…
material and almost no lava” (Volcano Types). Cinder cones are small volcanoes and tend to only rise about 1,000 feet and their craters are small and have steep sides. Though usually classified as a major volcano, they are much smaller than most other major volcanoes and can sometimes even form along the sides of shield and composite volcanoes. Composite volcanoes, also known as stratovolcanoes, are “symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash,…
Loowit to the Klickitat. Mount St. Helens is an active stratovolcano or composite volcano, a steepsided and often symmetrical cone constructe. Thess type of volcanoes tend to erupt explosively and pose considerable danger to nearby life and property of lava flows, ash, and other volcanic debris. Mount St. Helens takes its English name from the British diplomat Lord St. Helens in the late 18th century. The last eruption was on March 20, 1980. A 5.1- magnitude earthquake hit Mount St. Helen…
also created one of the biggest volcanic eruptions in it’s continent own continent. Towering at an outstanding 1 277 m or 1.277km in length. This volcano is known to demolish valley’s and places near it at an instant, due to it’s heavy and continuous lava flow when it has erupted. Mt Vesuvius is also well know for it’s toxic ash and debris because these substances caused the bodies of many people in Pompeii to rot. The last eruption of Mt Vesuvius was in…
The fragile molds were casted in the 19th century to preserve them further. A lot of mystery lays round them, because these people seemed to be frozen in time in contorted positions. It has recently been discovered that lava was not the cause of death for these people, the lava would have taken six days to reach the people of Pompeii. For decades, it was thought that the ash killed them by suffocation. A cast found covering their mouth seemed to prove this. But today, it is shown that this may…
Hawaii’s Kilauea versus Mount Fujiyama Ever since I was a little girl I have always been fascinated with volcanoes. How do they work? How hot is the lava exactly? Can you travel down into the funnel of a volcano, and if so how and will you survive? And do all volcanoes function the same way? As a child, we never understood that the beautiful hot magma that flows from the volcano is dangerous and burns everything in its path. Two volcanoes that have always caught my eye is Hawaii’s Kilauea and…
Would people recognize the difference between “active volcano” and “Holocene volcano?” Well there is no difference, people just use the term “active” wrong. Scientist say that, “...it is misleading to restrict “active volcano” to recorded human memories: we prefer to add another identifying word (“historically active” or “Holocene volcano”).” People are probably confused on what these terms actually mean because no one would see the difference or wouldn’t care. Volcanoes are very old, they…
The purpose of this paper is the explain a natural phenomena, Axial Seamount. Even if the reader has no knowledge of Axial Seamount, they will be able to fully understand the content of this paper. They will learn facts about Axial Seamount such as what it is, on what plates it is located on, what landforms are around it, etc. Axial Seamount is an underwater volcano located in the Northeastern Pacific Ocean, about 483 kilometers (300 miles) off the coast of Oregon. Because its frequent volcanic…
the times the volcano itself gives early signs of eruption. Some of those signs are small earthquakes beneath the volcano, swelling or increase heat and gases coming out of the volcano. A volcano is a mountain or hill, having a crater or vent where lava, rock fragments, hot vapor, and gases are being released from the earth's crust. One of the many active volcanos in the world is Mount Agung. Mount Agung to this day is still one of the many active volcanos in the world. Mount Agung is located…
