live on volcanoes are safe on many levels like some volcanoes people live on are super quiet eruption volcanoes and they do not erupt and explode like volcanoes people think of. But sometimes disaster do strike and a quiet volcano can become explosive because it is a composite volcano and it can kill and take out everything in its path. Living on volcanoes can be very dangerous if no one knows what their doing however it also can be very good for

Explain the differences between Basaltic‚ Rhyolitic and Andesitic volcanic eruptions with reference to processes‚ which lead to the eruptions‚ the type of volcano produced and the reasons for the differences between the material erupted by these volcanoes. Volcanic eruptions are caused by a red-hot liquid rock‚ called magma inside the earth’s core. Volcanoes erupt when magma rises to the surface of the earth‚ which causes bubbles of gas to appear in it. This gas can cause pressure to build up in

Being so close to an active volcano poses many risks to communities. Even though Mount St. Helens erupted over 30 years ago we know that it is still an active volcano. Future eruptions can kill and injure entire communities. Since the eruption in May of 1980 of Mount St. Helens‚ geologists have come to a better understanding of both the mechanics of volcanoes and the dangers they present to the environment and communities. Did you know that volcanic ash is actually small glass particles? Or that

In this essay I will tell you about the main parts of a volcano and it’s origin. The first main part I will tell you about is the magma chamber. A magma chamber is a large pool of molten rock‚ also called magma‚ sitting underneath the Earth’s crust. The magma chamber can be more than three miles below the Earth’s surface and the magma waits there for the pressure and gases to become too much to stay stable. The magma in the magma chamber is less tense than the mantle surrounding it‚ so it moves toward

is an important and interesting‚ as well as a destructive volcano. Mount Nyiragongo is located in the eastern part of Zaire‚ or the Democratic Republic of Congo in Africa. It is at a latitude and longitude of 1.5S‚ 29.3E. Like the majority of African volcanoes‚ is associated with the East African Rift and is part of Africa ’s Virunga Volcanic Chain. This mountain chain is one of Africa ’s most prominent geologic features ("Nyiragongo Volcano‚ Democratic Republic of the Congo"). With a summit elevation

volcanic eruptions known to man to date. As our text states‚ “this famous volcano erupted in the year 79 AD‚ ejecting a huge cauliflower-shaped cloud of ash and debris that rapidly settled to the Earth (Strahler 436).” After doing some outside research on this magnificent volcanic landform‚ I found quite a few things: “Mount Vesuvius is located in Italy‚ near the areas of the Tyrrhenian Sea and the capital of Italy. The volcano also buried two major cities ("Volcanic Eruptions: Mount Vesuvius").” Another

separately. Shield Volcano: Volcanoes formed by viscous lava and have broad and flat sides. This happens due to the lava cooling slowly which lets it spread widely before cooling. Magma: Molten or partly molten rock underneath the Earth’s surface. Seismic Activity: Release of energy from the focus of an earthquake that spread outwards like waves. 2: Epicenter and focus: Epicenter is on the surface of the Earth and focus is below where the seismic activity starts. Earthquake and volcano: Earthquakes

Mauna Loa: The Fiery Mountain Mauna Loa is Earth ’s largest volcano and most massive mountain as it takes up nearly half of the flourishing landscape of the island of Hawai ’i. This island is actually made up of five volcanoes‚ Kohala‚ Mauna Kea‚ Hualalai‚ Mauna Loa‚ and Kilauea‚ all in such close proximity that they fused together to form one whole island. Mauna Loa is located in the south central area of Hawai ’i‚ in the Hawai ’i Volcanoes National Park and its coordinates are 19°5 ’ N‚ 155°6

fact‚ 62 A.D. marks the date of a very large precursor earthquake. Because earthquakes happen so frequently‚ there are‚ consequently‚ related volcanic eruptions. Mount Vesuvius is a composite volcano. This type of volcano has many layers of lava and ash. There are two kinds of eruptions. A composite volcano like Vesuvius will erupt with two kinds of eruptions‚ but never at the same
