They are so high because of the many eruptions that already happened here. The debris were falling on the sides of the volcano, making it grow. A stratovolcano is able to produce the worst of all the eruptions: the Plinian eruption. It is called after a famous Roman naval commander and at the same time a scientist interested in natural and geological events, Pliny the Elder. He died while trying to get closer to the Mount Vesuvius that was erupting.
Geography PT Guide to Aerial Volcano by Rebecca Chin (9) 213 Geography PT || Ebook Formation of the Volcano on Aerial Island Aerial Volcano is a stratovolcano. It is a conical volcano with steep sides formed by the accumulation of hardened lava, rock fragments, and volcanic ash. [ fig 1 ] Magma erupt through one or more volcanic vents, which are openings on the earth’s crust. They are built up when eruptions occur. With each eruption, erupted lava and ash adds another layer to the growing volcano.
Pyroclastic flows are high-density currents of hot gases and volcanic fragments that move away from the volcano at a high speed. Pyroclastic flows can rush down the side of the volcano as fast as 100km/hour or more and reach temperatures as high as 1075°C. Pyroclastic flow is arguably the deadliest volcanic hazard. It is impossible to outrun. Those who get caught in it will be unable to breathe, and most likely burn to death.
Volcano Kilauea Hawaii Imagine this, the hard rocks underneath your feet. The wind blowing in your face, and hot lava streaming through the area. Lava rocks tumble down the bigger rocks with the sound of the lava popping, reminding you of the candy pop rocks. The steam flowing up like your boiling water and needing clean water badly. Keeping eyes out watching for predators, located in the mountains of Hawaii.
There have two theories about formation of the Hawaiian Islands. Unlike other volcanoes on the Earth, the Hawaiian chain sits squarely in the middle of the Pacific plate rather than on a tectonic boundary. In 1969, “hotspot theory” was purposed by J. Tuzo Wilson to explain this unusual placement. Wilson proposed that the linear geography of the Hawaiian Islands is due to the movement of the Pacific plate over a stationary point of great heat from deep within the Earth. The great heat from this localized hotspot melts the Pacific plate above the hotspot and the spreading seafloor along the plate boundary pushed over the rocky crust.
Situated on the border between Akita and Aomori district, Lake Towada is more than 46 km in circumference. It is formed by two large and deep holes which are the result of volcanic eruptions. Although Towada is not the largest lake in Japan, many tourists are excited by its stunning views with the blue water as a centered impression of the painting and abundant surrounding primeval
Hawaii and Yellowstone can be compared and contrasted in many ways. Yellowstone and Hawaii are great places to have a vacation with your family. What people don't know is that there are standing on super volcanos that could erupt at anytime. Giant chambers of molten lava just 8 kilometers below your feet. One time your enjoying the nature, next nature takes its toll and magma rushing up from the ground.
However, there is actually a particular weather phenomenon that is like a combination of lightning and a volcanic eruption. Sounds pretty scary but it is actually real. It is called a dirty thunderstorm but also known as thunder volcano or volcanic lightning. It is basically a type of thunderstorm, but the lighting doesn't come from the storm clouds, instead it is actually generated within the ash cloud that comes from the volcano, which is known to be the process of charge separation According to Martin A. Uman, who is one of the directors from the University of Florida Lightning Research program, the downward plume actually works as if it has a life of its own because it actually produces about 300 lightning bolts. Another study conducted by the Science journal said that when a ash, rock fragments and ice particles generated it produces electrical charges.
On May the 18th 1980, Mt Saint Helens in Washington State, United States of America erupted covering surrounding areas in ash, mud, toxic gases and lava. Mt Saint Helens is one of many active volcanos in the Cascade Mountain Range that runs along the Pacific Coast of the United States of America, a part of the Pacific Ring of Fire, named due to the many active tectonic plates in the region. The blast devastated an area of 20 square km. Within 10km of the summit, were there had previously been dense forest, no trees remained, beyond this area all trees were blown down. A further 600km2 was covered in ash and debris.
1.0 INTRODUCTION For the people of Malaysia, we are lucky because we are away from the volcano. Malaysia is vulnerable to natural disasters volcanoes, however, we need to know about volcanoes to understand the earth and our environment. Formed as a result of the volcanic magma accumulated beneath the earth 's crust. Temperature, very hot under the Earth 's crust caused the magma to melt. Magma flowing out onto the ground through cracks or vents and volcanoes known as lava.
