Stratovolcano

Japan is associated with so many natural disasters. This is because the island, Japan is located where the North American, Pacific, Eurasian, and Philippine plate meet, also known as plate boundaries. Japan is also located where the Pacific plate and the Philippine plate are subducting. This results in the stress building up where the two plates are subducting. How do plates move? Well, plates move when uneven heating in the mantle creates currents. This current is a convection current, and…

in history. Although these weren’t the only eruptions from Krakatoa, out of the multiple eruptions that took place, these were the largest and brought attention to the volcano. Source: (Facts, 2018) Type of Volcano: Krakatoa is an example of a stratovolcano, a tall, conical volcano with multiple strata of solidified lava, tephra, as well as volcanic ash. Source: (Villanueva and Villanueva, 2018) Formation of Volcano: -…

crucial component of the stratovolcano is a system known as the conduit system which also stored magma to advance to the surface (“Principal Types of Volcanoes”). Without this system, the debris erupted by the composite volcano would not be reaching the surface in order to help create the volcano itself. Lack of the conduit system would also lead to the natural process of erosion destroying the volcano’s cone (“Principal Types of Volcanoes”). The feature that makes a stratovolcano different…

Mount St. Helens is a volcanic stratovolcano still actively located in the Cascade Range in Western North America in the state of Washington. It was formed by a subduction plate boundary also located on the Juan de Fuca plate. The Cascade range is one of the most famous mountain ranges, and has one of the most active volcanos located in Western North America. Other areas or famous landmarks surrounding Mount St. Helens are the South Fork Toutle River, North Fork Toutle River, Castel lake,…

Mount Vesuvius is a stratovolcano, located on the West coast of Italy, on the Gulf of Naples and is the only active land volcano in Europe. Mount Vesuvius is 4,190 feet above sea level and is about 50km around its base (figure 1). It is over 17,000 years old and the last eruption occurred in 1944 which was during the Second World War. The volcano is best known for its eruption in AD 79 that damaged many houses and killed many people in the cities of Pompeii and Herculaneum. Furthermore, it is…

Good morning/afternoon, Mr Beier and 9B, today I will be comparing and contrasting two major volcanoes, Mount Tambora, and Mount Santa Maria. Before I go into detail about the similarities and differences of the volcanoes, I will provide some background information on how volcanoes are formed and how they work. According to Anderson, 2012, Volcanoes are defined as a vent, or opening, in the Earth’s surface through which molten rock, gases, and ash erupt. The word also refers to the form or…

Specific purpose: To inform the audience on what happened to Pompeii. Central Idea: Mount Vesuvius is a dangerous active volcano that has the potential to cause the equivalent damage or worse even today. Introduction I. “I looked round: a dense black cloud was coming up behind us, spreading over the earth like a flood. Many besought the aid of the goods, but still more imagined there were no gods left, and that the universe was plunged into eternal darkness for evermore.” A. These were the words…

of earthquakes and volcanoes. Krakatoa has erupted ten times within the last couple centuries and last erupted in September 2012, but on August 26th and 27th, 1883, it made history. Krakatoa is a stratovolcano, a tall, steep, cone shaped volcano that is usually very active. The lava of a stratovolcano is thick and normally doesn't move too fast, so it cools down and…

approximately 4,877 metres (16,001 ft) from its southern base in the plains near the municipality of Moshi to its summit height of 5,895 metres (19,341 ft).[2] Kilimanjaro is the highest volcano outside South America.[7] Kilimanjaro is a large stratovolcano and is composed of three distinct volcanic cones: Kibo, the highest; Mawenzi at 5,149 metres (16,893 ft);[8] and Shira, the shortest at 4,005 metres (13,140 ft).[9] Mawenzi and Shira are extinct, while Kibo is dormant and could erupt…

starts by introducing the terror of how destructive, volcanoes can be. There are two main activities that are associated with this eruption, the bombs, and the ash fall. The introduction, transitions to Dante’s Peak, which is a Composite volcano (Stratovolcano). Dante’s Peak starts indicating signs that an eruption is coming; different types of earthquakes, volcanic activity in the hot springs, carbon dioxide (CO2) levels in the air, sulfur dioxide (SO2) in the water supply and acidic lake…
