Nepal earthquake discussion
Never personally experiencing a geological event, I’ve decided to write about the 2015 Nepal earthquake. The accident occurred 25th April 2015 at exactly 11: 56 Nepal standard time, it had a magnitude of about 7.8 Mw. This accident killed about 9000 people and injured over 22000 individuals. The same earthquake initiated an avalanche on the tallest mountain in the world (Mount Everest) killing about 21 Nepalese. It also initiated another big avalanche in the valley of Langtang where two hundred and fifty people were missing due to the accident. Due to the effect of this earthquake, hundreds of thousands of Nepalese were rendered homeless. As the whole valley flattened (Scawthorn, 2011).
The main geological factor in the occurrence of this accident was the weakening of the underground plates. Geologically Nepal is subcategorized into 5 tectonic zones from east to west and south to north and parallel to subparallel. These tectonics triggers the occurrence of this earthquake in Nepal (Towhata, 2008). The information about the geology would actually help to minimize the accident in the area.
A study reported in the year 2014 showed that of the major Frontal Thrust there is a great earthquake which occurs every 870 ± 350 years in the Nepal area. The same study suggests that due to the tectonic stress build up, the earthquake from 1934 and that of 2015 were connected. Therefore with a clear calculation, people living around that area would prophesize of the occurrence of this earthquake and they would migrate for some time until the end earthquake. This would have actually minimized the death of most people.
A natural disaster I have personally experienced was the “1000 year flood” that occurred in October of 2015. This flood mainly effected Columbia, South Carolina, but it also impacted my hometown in Sumter, South Carolina. This flood completely devastated the Columbia area, as well as neighboring cities of Columbia. I know for my hometown, the flood effected each section of the city differently. My street was untouched and only received a small amount of rain. Roads 0.5 miles away however received enough water to wash the roads away. There are three entry points into my neighborhood, and two of them were washed away. The surfaces these roads were built on was a collection of compacted dirt, as well as porous and permeable rocks that allowed for too much water to saturate the foundation; ultimately causing the washout.
