Earthquakes and volcanoes are both related because they both form at plate boundaries. 5. The movement of plates causes earthquakes and volcanoes. 6. Magma chambers are large pools that hold the lava in a volcano.
This type of volcano can be recognized by its broad, gentle slopping shape. The lava dome that composes a shield volcano is usually built over a period of time. When this type of volcano erupts it often involves a flow after flow of lava. An example of shield volcano is Mauna Kea, which along with Mauna Loa forms the large island of Hawaii. The largest shield volcano in the solar system is Olympus Mons, on the planet mars.
Geologic Summary. The high, isolated massif of Shiveluch volcano (also spelled Sheveluch) rises above the lowlands NNE of the Kliuchevskaya volcano group and forms one of Kamchatka's largest and most active volcanoes. The currently active Molodoy Shiveluch lava-dome complex was constructed during the Holocene within a large breached caldera formed by collapse of the massive late-Pleistocene Strary Shiveluch volcano. At least 60 large eruptions of Shiveluch have occurred during the Holocene, making it the most vigorous andesitic volcano of the Kuril-Kamchatka arc. Frequent collapses of lava-dome complexes, most recently in 1964, have produced large debris avalanches whose deposits cover much of the floor of the breached caldera.
pyroclastic flow – scoria Which of the following sites would most likely have composite volcanoes? A is on an island arc, B is in the Andes, C is near Hawaii, D is along a mid-ocean ridge. e. A and B 9 The main hazard that Mount Rainier poses to Tacoma and its suburbs is d. volcanic mudflows What types of rocks would be most common in the volcano in this photograph? b. scoria and other vesicular basalt What is a main hazard of this type of volcano? c. hot fragments thrown a short distance from the volcano Which of the following volcanoes is generally the largest?
a. Volcano: include the type of lava, where magma is derived, and why this setting produces hazards b. Earthquake: magnitude and amount of displacement or offset 6. Describe the type of hazards in terms of cause, hazard definition, and location (example-tsunami inundation occurred within 1 mile of coastline in low lying areas). 7. Fatalities 8. Damage: 2-3 specific examples of structural damage (earthquakes); areas covered with volcanic debris (volcanic eruption); any other types of damage 9.
Discuss the view that the impact of the earthquake hazards depends primarily on human factors? An earthquake, a sudden violent shaking of the ground can be caused by a number of things from seismic activity and resulting in varying impacts. The cause of an earthquake are a result of built up pressure under the earth’s crust, the pressure comes from the movement of the tectonic plates, they can occur on any plate boundaries. Although the majority of the earthquake hazards come from the physical factors, human factors can determine the severity of the event. The impacts created from an earthquake can come from the physical factors of the size, the location of the epicentre and the surrounding areas such as a ground type and the lithology of the rocks.
Plate Tectonics Press Release Assignment Geology/101 An earthquake is the shaking of the ground cause by an abrupt shift of rock along a fracture in the Earth, called a fault. An earthquake is caused by the breaking and shifting of rock beneath the Earth’s surface. Ground shaking from earthquakes can collapse buildings and bridges; disrupt gas, electric, and phone services; and sometimes trigger landslides, avalanches, flash floods, fires, and huge, destructive ocean waves (tsunamis) (www.fema.gov/hazard/earthquake/facts). So the question that everyone wants to know is why does the planet move when the plates move? The planet moves whenever the two plates get tangled together.
Geologically, Aruba is more complex. The geological formation of Aruba’s geography is composed of three major rock groups; Igneous, metamorphic and sedimentary. To the reader who just looks at the textbook, this means that Aruba (the Island) was there long before the late 15th century when the Spanish first came here. Actually, Aruba was formed from the process of volcanism some 90-95 million years ago. The Island of Aruba is the result of lava hardening from a volcano that occurred almost 100 million years ago underwater.
For example, the origin of puzzling, hilly volcanic deposits near Mount Shasta and Mount Rainier became clear. Gravitational collapse of volcanic flanks is now seen as a normal event at steep-sided volcanoes, even on the ocean floor and on other
Japan is a country that lies a hundred km from where tectonic plates are clashing at a convergent boundary, with one plate being dragged beneath the other. These tectonic plates are very thick rating, from 10km to 50km and are in motion with respect to each other. In Japan, they tend to move at rates of eight to nine centimeters yearly hence the result is a collision, with one plate forced to go beneath the other. If enough stresses build up from this sticking, then finally there will be a sudden slip which produces an earthquake. Japan is well known for being particularly amenable to subduction zone earthquakes, with huge pressures brought to bear by the sticking tectonic plate zones nearby it, and the slipping results in many earthquakes, some of them very big for instance the Tohoku earthquake.
