Seismic hazard

Summary of proposed research Seismic hazard analysis is an important tool in mitigating risks in the event of a disastrous seismic event like an earthquake. This can be done by studying the behaviour of the soil in locations that are within seismically active regions using several geophysical methods. This project employs the use the cost-effective microtremor method in studying the site response in Kathmandu, Nepal, following the April 25, 2015 M7.8 Gorkha. Analysis of the field data will yield

Recognition of the hazard is one of the most important components of Disaster Management. For any Hazard analysis, zonation of the area is very important. For seismic hazard analysis there are two methods of zonation-Macrozonation and Microzonation. Macrozonation is used for seismic zonation at regional level on small scale considering broad parameters, while microzonation is mainly used for urban area considering local parameters and site conditions for seismic hazard analysis, at large scale

Nevada Hazards Wendy Gurganus Coastal Carolina Community College One of the geologic hazards in Nevada is the Mountain ranges. The reason these are hazards is because most of the ranges in Nevada have a major fault line on either side of them. Some of these faults have been active within the last 1.6 million years, and have had large earthquakes. This causes the ranges to tilt and shift and raised the ranges to higher levels. As far as seismic activity goes, Nevada is the third most active

Geological Hazards of Missouri Daniel LaBounty Geology 111C, Section 04MH Mr. David VanDeVelde July 3, 2015 Geological Hazards of Missouri Although many may not consider Missouri to be a hot spot of geological related natural disasters, there are multiple geological hazards which occur throughout the state. According to the Missouri Department of Natural Resources Geological Survey Program, the hazards most often occurring in Missouri are earthquakes, landslides, sinkholes and abandoned

instance, the California Seismic Safety Commission in 2005 estimated that by the end of 2015 damages from earthquakes in these regions will likely exceed $30 billion. An annual report in 2007 by the Federal Emergency Management Agency (FEMA) estimated that almost 75%

from all hazards for the people, properties, and governments within the United States. Successful emergency management includes a functional approach to all emergencies, mutual planning, correct use of physical and monetary resources, and shared responsibilities among federal, state, and local government. The concept of Emergency Management is a four phase process that includes Mitigation, Preparedness, Response, and Recovery. Response and Recovery take place both during and after hazard/emergency

local officials created a detailed, comprehensive plan that integrates mitigation planning and action framework, unlike other local hazard-mitigation plans. The essential difference amongst Roseville plans and other cities is that “Roseville has well exceeded the minimum disaster mitigation act of 2000 requirements for citizen involvement by formulating the Roseville Hazard Mitigation Plan through a variety of robust outreach measures.” (Schwab, 2010). The local government’s strong mitigation action

Disasters, at their most basic, arise when hazards have a significant impact on a population. A 7.0 magnitude earthquake that would be a devastating disaster in a densely populated and vulnerable city, may be a relatively insignificant geologic occurrence when it strikes an unoccupied island chain. Risk of a disaster is more traditionally calculated by identification of the potential hazard, assess in relation of likelihood of an event as it relates to the potential impact severity – or risk = probability

However, by undertaking these preparations whenever there’s a chance of a natural disaster, a government may find itself in a predicament if the disaster never occurs. In the Mount Pinatubo scenario, geoscientists were afraid of raising their warning to level 2 or level 3, because an evacuation would require time, labor, and money, regardless of whether the volcano actually erupted. People might panic, leading to unnecessary casualties. Moreover, such a severe warning could scare away tourists and

“DISASTERS CREATES OPPURTUNITIES FOR DEVELOPMENT” DISASTER: Disaster can be defined as “The occurrence of a sudden or major misfortune which disrupts the basic fabric and normal functioning of a society, or community.” “An event or series of events which gives rise to casualties and/or damage or loss of property, infrastructure, essential services or means of livelihood on a scale which is beyond the normal capacity of the affected community’s ability to cope with out aid.” According to UNISDR
