Walnut Heights: A Case Study

One reason why people shouldn't live by volcanoes are pyroclastic flows, pyroclastic flows are high speed avalanches of hot ash,rock fragments, and gases. “These pyroclastic flows which can reach 1,500 degrees fahrenheit and move 100-150 mile per hour that are capable of knocking down and burning anything in its path” (Pacific Disaster Center). More than 2,000 people died from pyroclastic flow surges during the 1982 eruption of El Chichon in southern mexico.

My inference is that Haiti is at high risk from earthquakes and needs better and houses that are more safe.Haiti is at risk because it is over a plate boundary. Haiti is on the Caribbean Tectonic plate and I also found out that it is on top of smaller plates.. The northern side of Haiti is on the border the Caribbean Plate and North American Plate. This plate boundary is a convergent boundary between an oceanic plate and a continental plate. Since oceanic plates are less dense than continental plates, there will be a subduction zone. The subducting zone is on the pacific and north american plates.What I want to do is that we make safer houses so that the wind can not do any damage so people wouldn’t have to trave`l somewhere else and can stay

Last night a magnitude 7.0 earthquake struck the greater salt lake area causing severe damage to a number of vital areas in the valley. Experts have pointed to the I-80 and 1300 East as the epicenter of this quake. There is severe damage to buildings in this immediate area as many building here were built with un-reinforced brick. Many of the roads including the I-80 are inaccessible making travel in the area very difficult to navigate. Another tragedy in this event is the damage to the area around many of the hospitals in the north east part of the valley. While the hospitals themselves did not suffer as much damage the roads leading up to them did not fare as well. If we look further to the west at the airport, there is considerable damage

Thank you, Ms. Leona Graham (mayor), for the opportunity to provide an assessment report for Hazard City. This report will provide an assessment on structural damage of an Intensity IX earthquake, and emergency housing needs. It will also identify actions homeowners can use to help prevent future structural damages, and give more information on possible effects of an Intensity IX earthquake. The assessment report will identify danger of a failing dam, and provide further understanding of the elements which will include an emergency plan. The table that follows is an assessment of the number of people needing emergency housing due to an Intensity IX earthquake.

Earthquakes are something that happen every day all around the world. Most earthquakes are very small and go unfelt, however every once and while there are massive earthquakes that cause tremendous damage to life and property. Sonoma County has a lot of fault lines running through it. These faults line are; the San Andreas Fault, the Rodgers Creek Fault, the Maacama Fault and the Healdsburg Fault. Since 1855, there have been more than 140 earthquakes that have actually been felt where we live in Santa Rosa Area Of the earthquakes that have cause damage, the worst damage was caused by; 1906 San Francisco Earthquake, 1969 Rodgers Creek/ Healdsburg Fault Earthquake, 1989 Loma Prieta Earthquake, 1994 Northridge Earthquake. We should use the data of past earthquakes in our area to help come up with a plan in case there is another major earthquake in Sonoma County. Data suggests that there is a 63% probability of at least one magnitude 6.7 or greater earthquake striking somewhere in the San Francisco Bay Area before the year 2032. The key to surviving and earthquake is to be prepared.

Our natural hazard is a hurricane. They can go up to 70 to 200 miles per hour wind speed. Each hurricane lasts up to about a week. They are huge storms that run on water. They are able producing to about 200 times of the world's electricity. Hurricane winds can rip off roofs, blow out windows and flatten buildings. and they’re notorious for making deadly weapons out of random debris. Hurricanes can also make tornadoes, which have even stronger winds. They create sink holes. There have been many hurricanes some worse than others. One of the worst hurricanes to ever occur was Hurricane Galveston.

This week I learned about the dangers associated with hurricanes and tornadoes and the cities that are often affected by these dangers. If I know the dangers and the places often affected by these natural hazards, I can then better

Calamities can greatly affect homes and other infrastructures. Regardless of how the disaster ravaged the home, it is absolutely essential to promote safety as soon as possible.

Oregon's current building code, or Oregon Structural Specialty Code, outlines that new buildings will be seismic resilient, but roads, bridges, electrical and telecommunications, water and septic lines were assessed as not being able to withstand a 9.0+ magnitude earthquake. These sensitive areas, called "lifelines", can severely hamper recovery efforts if damaged. Notably, Oregon's "lifelines" where constructed to a quality below current seismic safety standards. Currently Oregon is working to understand lifeline locations and their relationships and interdependencies to create a more robust earthquake safety policy that will positively affect towns, cities and outlining communities such as the Sandy River and Hood River corridors. Coastal geologists regularly revise tsunami inundation data, via computer models, to provide better advisement to the communities along the state's 362-mile coastline. Currently, a multi-year program funded by the National Tsunami Hazard Mitigate Program and overseen by the National Oceanic Atmospheric Administration, called TsunamiReady. It provides further assistance and resources to established local social programs focusing on awareness and

My topic is going to revolve around earthquakes in the Western coast of the United States of America. Earthquakes have interested me ever since I was a little girl. I went through probably 3 earthquakes in my childhood. One of them was in Corona, California. I was about 5 years old when it happened. The other one was here in Santa Rosa, and I was about 4 years old. I remember my mom being pregnant with my little sister when it happened, and I remember running down the stairs of my house with her. My dad worked (and still works to this day) in San Francisco, so she called him to ask if he was okay. Anyways, I believe that one day scientists will be able to predict earthquakes, just like they predict the weather. I really hope I get to see the

The analysis of the seismicity data around the site under investigation is carried out to define the design or credible earthquake. The design earthquake is a term representing the largest earthquake and/or ground acceleration expected to struck the site over a certain time window. The approaches used to define the credible earthquake may be classified into deterministic and probabilistic. The deterministic one inspects the seismic history around the site to pick the largest reported event in the catalogue.

While these occurrences may not happen in frequency in Columbia County, they are very important elements to take into consideration for this hazard mitigation plan with contingency plans in place. Especially population growth and environmental degradation because the area is growing so rapidly in such a short period of time.

A failure in the interior of the Earth’s crust is the cause of most earthquakes. Once the stress inside the crust grows beyond the strength for that location of the crust, a failure occurs within the crust and seismic waves, which we know as earthquakes, are radiated outward. It was once thought that this description of seismic activity was the cause for all earthquakes, but now seismologists know the way earthquakes form and start is a very diverse process. Most earthquakes are classified in the category of being brittle failures, which generate strong seismic waves; some earthquakes involve slow slip motion. There is also evidence to suggest that some earthquakes are more of a thermal process due to large amounts of heat generation, rather than large seismic activity. (Scholz 2002) Also, some earthquakes are not the result of faulting however, but caused by large landslides. In the early days of seismology, these differences were noticed qualitatively but the technology available during that time made it hard to accurately tell the difference. Before an earthquake takes place, there is a large buildup of potential energy. The energies involved in earthquakes can be described by the elastic strain energy W, plus the radiated energy Er, the energy mechanically dissipated during an earthquake, Eg and the thermal energy due to heat dissipation, Eh. Since this equation is a description of potential energies, the actual event of an

A serious earthquake stroke Tokyo and the adjacent areas on September 1st in 1923. According to the scholar Michael Allen, the earthquake took away more than 100,000 people’s lives and caused an immense loss of properties (Allen, 64). I historically called the Great Kanto Earthquake. Since the earthquake occurred at noon and most families were cooking by the time, fires started in many places, leading to even more obstacles in rescuing and causing people to be in great panic.

The Topsham community in Portland, Maine pertinent risks and hazards will be discussed. It 's current state of readiness is exceptional. The purpose of the Topsham community Hazard Mitigation Plan is to provide a comprehensive set of guidelines for hazard response and mitigation in the community. The plan identifies potential risks with appropriate mitigation responses to significantly reduce loss of life, injuries, economic costs, and destruction of natural and cultural resources. As the occurrences of the hazards identified in this plan are unpredictable, the plan itself will continue to evolve and be evaluated. With this, the mitigation strategies and maintenance process will be labeled as ongoing. The mitigation strategies and maintenance of the plan provide direction for the future of mitigation activities within the state and the process will continue until changed for any valid reason. The community has made progress on
