Oregon Seismic Safety Policy

A natural disaster has the capability to cause large scale damage and destruction to an area. Seismic events have been known to alter landscapes and affect the livelihoods, health and development of communities. No two earthquake events are the same and the level of threat posed by an earthquake can vary due to both the human and physical factors of an area. The 2010 magnitude - 7.0 earthquake that occurred in Haiti is an example of where a natural disaster caused a previously vulnerable area to suffer tremendous loss and debilitating socio-economic impacts, to an already poverty-stricken nation.

Fault. As I researched, the reality of the potential effects to our state came into light. To be perfectly honest, I don’t think I had ever even heard of the New Madrid Fault. It could have been mentioned in my 7th grade Earth Science class, but that’s been a few years ago. As my internet investigation into the New Madrid Fault unfurled, the predictions of a massive earthquake happening in the region within the next 50 years was mentioned a number of times. So I thought I would begin my research into the history of the New Madrid Fault in regards to our state. Which lead me to think is our state prepared for an earthquake? What would the response be, not only from an emergency management point of view, but I will draw from my experience as a member of the Air National Guard.

California’s unique geography as a state makes it a very appealing place to call home. From the odd east to west transverse San Gabriel mountain ranges of the Los Angeles Basin, to the bumpy coastal ranges of the Bay Area, any person can find a compatible topographic terrain to their liking. California may seem to be the perfect place to live with its ideal climate and extensive geographic features. However, due to California’s location over the shifting continental plates, coupled with its enormous and also multiple faults, at any time this great state can fall victim to a seismic disaster. After examining evidence from both Rong-Gong Lin’s II Los Angeles Times article of April 18, 2016 and the NOVA videos Killer Quake ( 2006), Earthquake (2007), as well as Geologic Journey II – Episode 3 (The Pacific Rim: Americas) – Part 3 (San Francisco) and The Great San Francisco Earthquake (American Experience ~ 2005), one can take a comparative account of the three major earthquakes of California’s past. Although each earthquake was very devastating on is own; the Great Quake 0f 1906, the Loma Prieta quake of 1989, and the NorthRidge quake of 1994 each amounted to an extensive forfeiture of property and life. Each of these earthquakes created much suffering and loss. It is imperative for each citizen of this great state to understand the damage that a California quake can actually do and be prepared; for the threat of one always looms.

Kathryn Schulz has provided insight of the dangers of the Cascadia Subduction Zone and the lack of our countries preparedness. Seismologist has detected and proven probability of an enormous earthquake and/or tsunami that is over due to take place along the western coast line and yet the lack of preparedness is evident. Thousands of lives will be lost due to unpreparedness.

According to the research report, it will cause thousands of people die, towns submerged, buildings and bridges damaged once a huge earthquake and tsunamis happened on the Pacific Northwest area near American coast. And losses will be estimated at over 5 billion dollar US dollars. This shocking article was composed by seismic safety advisory committee in Oregon. According to materials, a super-strong earthquake once happened in A.D. 1700 Cascadia Subduction Zone (CSZ) on the Pacific Northwest coast. There are some experts forecast that another super-huge earthquake will occur in the future. The report has shown that once the earthquake occurs, the regions from North California to British Columbia Coastal region will suffer devastation, cause heavy casualties. Water and electricity shortage issues definitely follow this heavy disaster, meanwhile, communication and heating system and gas supply will definitely broken off in the light of this earthquake. The CSZ is a 1,000 km long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino in northern California. It separates the Juan de Fuca (Juan

“The Really Big One” is an article by Kathryn Schulz about the Cascadia Subduction Zone, a fault line that runs seven hundred miles along the West Coast. It consists of two tectonic plates where one plate is sliding underneath another. In this case, the oceanic plate Juan de Fuca is sliding under the continental plate known as the North American plate. In her article, Schulz repeats the words of seismologists and scientists alike in the opinion that the Cascadia Subduction Zone is overdue for a magnitude 9.0 or higher earthquake and resulting tsunami. No one in the Pacific Northwest is prepared for it. With historical stories and examples from around the world Schulz warns of the damage to be done when the “Really Big One” finally makes itself known.

We learned that Little Cottonwood Canyon is home to geological history, varying rock formations, earthquake potential, ancient glacial formations, landslides, and our effect. This Canyon runs along the Wasatch fault and has much potential for large earthquakes. The mountains have been carved by glacial formations dated back to the Ice Age. Rock falls and landslides have left large boulders as evidence of erosion and moisture in the rocks. The hazards on this mountain range are mass wasting, radon, earthquakes, and the flooding of Little Cottonwood

Currently, the prediction of the “Big One” is causing a lot of disturbance and fear among people who lived along the coastline of British Columbia. The “Big One” stands for a Cascadia Megathrust earthquake with magnitude around 9 and it has at least twelve percent probability of hitting Vancouver within the next fifty years ( ). The validity of this prediction has been questioned by many, however, scientific explanation has proven that the “Big One” will happen in the future sooner or later. British Columbia has the highest earthquake risk in Canada; several thousand small earthquakes are recorded in B.C. every year. Therefore, the “Big One” is going to happen, and it will cause different scales of damage such as geological and economical

Ensuring Resilience to Disasters has more tasking’s than another mission and involves many different agencies to accomplish those tasks. The four tasks are to mitigate hazards, enhance preparedness, ensure effective emergency response, and rapidly recover. The main agency that is responsible for these tasking’s is FEMA. FEMA’s mission is to “reduce the loss of life and property and protect communities nationwide from all hazards, including natural disasters, acts of terrorism, and other man-made disasters” (FEMA, 2017, p.2). FEMA works with federal and State services to assist them in accomplishing their goals. They also assist local services by assisting in setting up emergency management agencies (LEMA) and set guidance for Emergency Operations Planning (EOP). EOP’s are “plans that provide an overview of the jurisdiction’s preparedness and response strategies. It describes expected hazards, outlines agency roles and responsibilities, and explains how the jurisdiction keeps the plan current.” (FEMA, 2010,

The natural environment is, of course, not “getting its revenge”. Geophysical, meteorological, and hydrologic processes are unfolding as they have for millennia, beginning long before humans occupied the earth and continuing to the present. Given the eons-long perspective of the natural environment, it would be very difficult to identify meaningful changes in event frequency for the short time period in which scientific records are available on geological, meteorological, and hydrological phenomena. Event frequency, from an emergency management perspective, is not really the issue. It is certainly true that, over the years, more people have been affected by natural disasters and losses are becoming progressively greater. The significant feature driving these observations, however, is the extent of human encroachment into hazard prone areas. With increasing population density and changing land use patterns, more people are exposed to natural hazards and consequently our accumulated human and economic losses are increasing. Much of this exposure is a matter of choice. Sometimes people choose hazardous places, building houses on picturesque cliffs, on mountain slopes, in floodplains, near beautiful volcanoes, or along seismic faults. Sometimes people choose hazardous building materials that fail under extreme environmental stresses—for example, unreinforced masonry construction in seismically active areas. Some exposure results from constrained choices; the cheap land or

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.

A swarming number of 30 earthquakes have happened in less than 19 hours, weather.com reports. Two earthquakes happened within 30 seconds of each other. The first had a magnitude of 4.7, and the second had a magnitude of 4.8. All 30 earthquakes have happened in the state of Oklahoma. Home to Oklahoma City, Fairview, and other highly populated cities. The earthquakes were felt as far as the eastern Texas panhandle, Kansas, Wichita, and many other near places around the map. What is so crazy about this certain event is that there were only 42 earthquakes TOTAL in Oklahoma in 2010. Within 19 hours, Oklahoma has managed to almost reach the number. According to USA Today, the state has hit 70 earthquakes in a week. Oklahoma is home to huge gas and

Have you noticed the amount of natural disasters that have occurred lately? Recently, natural disasters have been happening such as hurricane Harvey, Irma, and the 7.1 magnitude earthquake Mexico experienced. Sadly, California could be next to be hit from an earthquake.

Earthquake Hazards occur when there are adverse effects on human activities. This can include surface faulting, ground shaking and liquefaction. In this essay I will be discussing the factors that affect earthquakes, whether human such as population density, urbanisation and earthquake mitigation or physical such as liquefaction, magnitude, landslides and proximity to the focus.

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
