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
A risk assessment shows that the chances of a volcanic eruption in the next 10,000 years is 1 in 10, 0000 ("Volcanic hazard at," 2002). This region has had some volcanic activity within 12 miles of the Yucca Mountain. Some of the eruptions have caused some levels of magma. Because of the level of volcanic gases contained in the magma the eruptions have been explosive ("Volcanic hazard at," 2002). This could be a problem if an eruption was to take place at the Yucca Mountain or close by.
One of the ways to get it is called fracking. Fracking is short for hydraulic fracturing. What is fracking and what does it do to the environment? Fracking is a process where millions of gallons of a mixture of liquid are inputted into the ground at high pressure to break the rock surrounding the natural gas. Then the natural gas is discharged from the ground into a well.
They can cause widespread destruction, such as the 1980 eruption of Mt St Helens. Lahars are a secondary effect of a volcanic eruption and are cement-like mudflows consisting of volcanic ash and water. They often occur in the days following an eruption when people are at their most vulnerable and with the capacity to travel up
I will be discussing factors that cause differences in hazards posed by volcanoes. I believe the most important factor is the location of a volcano and the type of volcano. The most explosive and therefore dangerous volcanoes are found on destructive plate boundaries (Over 80% of the worlds volcanoes occur at these boundaries) for example the eruption of the Nevado del Ruiz in Colombia on the 13th November in 1985 which killed over 25000 residents of Arenas and Armero. At destructive plate margins, the oceanic crust is denser than continental crust and is therefore subducts under the continental crust. Due to high temperatures in the mantle of around 3000 degrees centigrade, this oceanic crusts melts and then rises due to the convection currents in the aesthenosphere .
The top section of the building tilted to the east and to the south and began its descent. The time from aircraft impact to collapse initiation was largely determined by the time for the fires to weaken the perimeter columns and floor assemblies on the east and the south sides of the building. World Trade Center 2 collapsed more quickly than World Trade Center 1 because there was more aircraft damage to the building core, including one of the heavily loaded corner columns, and there were early and persistent fires on the east side of the building, where the aircraft had extensively dislodged insulation from the structural steel. The World Trade Center towers likely would not have collapsed under the combined effects of aircraft impact damage and the extensive, multi-floor fires that were encountered on September11, 2001, if the thermal insulation had not been widely dislodged or
I shall use examples of the Kobe Earthquake 1995, Boxing Day Tsunami 2004 and the Haiti Earthquake 2010. The earthquake of 2004 was caused by subduction of the Australian plate and the Eurasian Plate ,a 15-20m slip occurred along the fault line which then caused an earthquake measuring a 9.1 on the Richter scale. This a very high recording on the Richter scale so therefore it would always cause devastating hazards , but human factors could be seen as making the impacts far worse. The earthquake in the ocean had caused a tsunami to occur within the Indian Ocean. The wave reached up to 30 metres high causing devastation to the 13 countries surrounding the ocean.
8 H October 26, 2012 1886 Charleston Earthquake In Charleston August 31, 1886, a devastating earthquake shocked millions throughout the country. Not only was this earthquake reported in South Carolina, but in distant places such as Boston, Massachusetts, Milwaukee, Wisconsin, Chicago, Illinois, Cuba, Bermuda, and many more. Why so many places? The earthquake recorded a 7.4 on the Richter scale. This tells us that it’s a powerful earthquake, reaching and being felt by farther away places.
[Stephen] Horton [a seismologist at the University of Memphis] and others investigated a swarm of earthquakes in 2010 and 2011, including one of magnitude 4.7, in an area of central Arkansas where fracking was being conducted. The scientists found that the earthquakes were probably caused by fracking and the disposal of waste liquids from the process into other wells.” (Mead) Furthermore, air pollution is another factor that must be taken into consideration. Near the end of the well development process, something happens called flaring. Flaring is used to get rid of the waste gas that is not able to be used. The gas is purposefully set on fire, leaving flames to spew far into the sky, burning for several days continually.
General economic standing: 4. Has the tectonic setting (which also influences the geography or landforms) influenced population concentrations? 5. General description of the earthquake or volcano in terms of tectonic setting, frequency or historic activity, why event occurred (volcano and subduction zone generally produce viscous lava and violent eruptions) or (earthquake and subduction zone are capable of producing large volume of crustal movement =large magnitude earthquakes and tsunami). 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.
