Earthquake Risk Management Essay

1342 Words6 Pages

Assessment and monitoring of any natural Hazards like cyclone, flood, earthquake, landslide, etc. in a region are of vital importance for the enterprises responsible for disaster risk reduction (DRR) and disaster risk management (DRM). Such studies provide fixed tools that help in better infrastructure development planning, mitigation measures and also foster in developing early warning preparatory system. The paper here essentially deals with the hazards emanating from earthquakes, the contributing factors to earthquake hazard, and the source and cause of earthquake hazard within the study region.
Thus earthquake is one of the natural disasters that are common around the world that cause wide spread damage and death. According to Gupta (2003), earthquake damage within a region may perhaps differ locally, since it depends on the types of infrastructures that are built and the subsurface ground conditions, nearness to faults and fractures, bed rock structures and the unconsolidated substrate saturated with water. Earthquakes normally occur due to tectonic plate motions acting on the geological settings of the site. It has been reported by …show more content…

Earthquake hazard is the main reason behind the collapse of a lot of potential infrastructures due to shaking, especially when the proper adherence to building codes is not observed. If a building, bridge, road or any infrastructure that is built on unconsolidated or saturated soils and sediments, such an infrastructure is prone to collapse during earthquake events of larger magnitude at shallow depth, risk aggravated due to liquefaction or landslip that might ensue. Adequate understanding of the levels of each hazard zone will assist in better planning for infrastructure development and hence will aid in maintaining and improving economic growth of the

    Question Set 7 A) What types of methods and tools are used to measure, document and analyze ancient fault activity along the San Andreas Fault and its associated faults? For example, how do geologists determine how long a fault has been active, how often it ruptures, its relative offset motion, and how much offset? Note that the term "ancient" means fault activity that occurred thousands to millions of years ago - long before seismologists were around.
