Pakistan earthquakes

Earthquakes

For week 3, earthquakes in Pakistan. But first a brief introduction to earthquakes in general to understand the effects of earthquakes and why earthquakes occur, first we need to know the causes of these boundaries. Earthquakes occur along the plate where the earths crust which is the weakest part known as the fault. A fault is a semi-planar fracture system where rocks have been moved to the other side (Keller 55). The earth is a dynamic evolving system in which the movement of tectonic plates results in the formation and destruction of ocean basins and uplifts mountains, and the process is active along the boundaries of the phosphoric plates where faulting occurs (Keller 54). In Keller, geologists use centuries old mining terminology to describe the rocks and that are displaced across the faults, because many early mines were dug into the earth along inclined surfaces to mine mineralized ore veins along fault zones (55). Most importantly, when a fault rupture occurs such as rocks breaking apart suddenly and violently. It releases a stored elastic strain energy in the form of seismic waves which produces a strong motion that passes through the ground under our feet that we perceive as a earthquake which cracks the ground and damages buildings and others structures (Keller 59).  


Pakistan's earthquakes history and what are they doing to prevent these events from occurring.
An example"A major earthquake shook Pakistan on Saturday, October 8, 2005, at 8:50 a.m. The epicenter of this magnitude 7.6 quake was about 65 miles north-northeast of Islamabad, the country’s capital. At least 86,000 people were killed, more than 69,000 were injured, and extensive damage resulted in northern Pakistan. The heaviest damage occurred in the Muzaffarabad area of Kashmir" (Tuz). Also the more I researched about Chi Tuz, their a foundation that helps people who have suffered from a major natural tragedy and trying to do their part to the community. What is Pakistan's government doing to prevent earthquakes from happening, i was reading an article that said what the government says only looks good on paper but in person have nothing to show for. From the article "Pakistan 'nowhere near prepared for another major disaster" measures introduced by the Pakistan government to reduce the risk and impact of disasters may look good on paper, but the reality is marked differently, according to a research study commissioned by the Disaster Emergency Committee. Also, Pakistan  is nowhere near prepared for another major disaster like as the example in 2010, and isn't even prepared for the much smaller disasters you would expect in a country with the geography and other issues they face.
