The planet moves whenever the two plates get tangled together. The energy that moves the plates become saved and whenever that energy is ultimately releases it triggers the planet earth in order to shake (Nelson, 2011). Earthquakes are measured with a seismometer, which is also known as a seismograph. A seismometer measure as well as notes the moves under the Planet’s surface which includes seismic waves triggered by earthquakes. A seismometer permits seismologists to produce a map of the Planet’s inner surface.
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.
Earthquakes Sheila Fangmeier GEO101 – Earth Science Colorado State University – Global Campus Karen Stelly October 5, 2014 Earthquakes “An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves” (Earthquake, 2014). Seisometers measure earthquake magnitude and intensity based on two scales, the Richter and Mercalli. An earthquake’s magnitude can range from less than 2.0 to greater than 9.0 on the Richter scale and its intensity I to greater than VIII on Mercalli (Richter magnitude scale, 2014). The depth focus is important to how much damage can occur on the Earth’s surface. An earthquake’s depth can be considered shallow (less than 70km), intermediate (between 70km and 300km), or deep (300km to 700km) (Earthquake, 2014).
2. Lava Flows is the lava that slide down the side of the volcano. The dangers of hot lava meeting the surface are streams that resulted from the boiling of the salt water and the instantaneously change to a crystal. The water temperature where lava meets water is 30 -69. Volcanic Gases 1.
There is a convergent boundary on the west side of the United States. At a convergent boundary, two plates collide, and the denser plate is subducted. Volcanoes and earthquakes are common as a result of pressure and friction. There is also a transform boundary forming the San Andreas Fault which is between an oceanic plate subducting under a continental plate. 3.
At last for conservations margins, the tension build up when plate are grinding past each other get stuck. Afterwards the plate will finally jerk past each other and sending out shock waves which is vibrations which is earthquakes. They both create lots of impact. For examples for the volcano eruption in Montserrat which is a LEDC, it cause 19
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?
Today, its importance comes more from the wealth of scientific knowledge derived from it than from its sheer size. (USGS) Rupturing the northernmost 296 miles (477 kilometers) of the San Andreas Fault from northwest of San Juan Batiste to the triple junction at Cape Mnemonic. The earthquake confounded contemporary geologists with its large, horizontal displacements and great rupture length. At almost precisely 5:12 a.m., local time, a for shock occurred with sufficient force to be felt widely throughout the San Francisco Bay area. The great earthquake broke loose some 20 to 25 seconds later, with an epicenter near San Francisco.
Helens was the first “laboratory volcano” in the continental U.S. where seismologists had the opportunity to study the reawakening of a volcano and patterns in volcano-generated earthquakes. Recognition of earthquakes that heralded the 1980 reawakening of Mount St. Helens illustrated the importance of having seismic sensors and a working telemetry system at a volcano prior to the onset of volcanic activity. (In a stroke of good fortune, the UW Data Acquisition System (DAS) became operational on March 1, 1980, the very first DAS to ever operate in the Pacific Northwest). Between 1980 and 1986 scientists identified specific earthquake patterns as reliable precursors to lava-dome building eruptions. Scientists have since seen these patterns as precursory to eruptions at many other volcanoes, including the 2004-2008 eruption of Mount St. Helens.
Haiti Earthquake, January 2010 Terrah-Leigh Ann Pietersen On the 12th of January, 2010, an earthquake struck Haiti which measured up to 7.0 on the Richter scale. This caused an estimate of 230, 000 to 316, and 000 to have died. The earthquake was produced form the fault line that separates the Caribbean tectonic plate from the North American plate. The fault line ran from east to west. It was miles away from the capital called Port au Prince.
