Module 1 SLP: Three Types of Disasters or Emergencies

The San Andreas fault line has caused constant development nightmares for large urban areas such as San Francisco as well as the other cities built on top of it. Fault lines are one of the side effects of the earth’s tectonic plates shifting that can result in devastating earthquakes. Some of the most devastating earthquakes in our modern era have occurred along the San Andreas fault line due to a dense population. The most notable and destructive earthquake on the San Andreas fault line occurred in San Francisco in 1906. The reason this earthquake was so deadly was because of its magnitude and the city’s poor planning. This earthquake was a wakeup call for San Francisco and force the city to revolutionize its knowledge on earthquakes and how to protect their city. Today San Francisco is one of the most well prepared cities for an earthquake and has made great discoveries in earthquake safety measures. The 1906 earthquake in San Francisco has drastically changed how the city has developed its zoning and building code policies, and its earthquake research.

The San Francisco earthquake on April 18, 1906 was one of the most devastating earthquakes felt by a lot of states. At 5:15 am, this earthquake which registered at 8.25 on the Richter Scale shook San Francisco, California. The earthquake lasted less than a minute and it did a lot of destruction in that period of time. The most destructive part during the San Francisco earthquake was the fires which began after, as a result of the earthquake. The fires killed about 3,000 people and left 400,000 homeless (San Francisco Earthquake). The San Francisco earthquake epicenter was located near San Andreas fault and as a result, the damages caused by the earthquake was felt many miles along the San Andreas fault line. The city of San Francisco was known for its culture and economy, and because of the impact of the earthquake and fire, the city was in total disaster. Because of the magnitude of the earthquake and the amount of damage it did to the city of San Francisco, a lot of data and digital images have been collected so that it can be used for references and be displayed at its anniversary.

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.

On August 24, 2014 a magnitude 6.0 earthquake occurred in and around the city of Napa, CA. The earthquake killed one person and injured over 150 people. And these people were treated at Queen of the Valley Medical Center in Napa [1]. More and more earthquakes occurred on this earth. So this grasps people’s attention.

Tragic events that cause damage to property and life may destroy the social, cultural and economic life of a community. Communities must be engaged in the various phases from prevention to recovery to build disaster resilient communities. In order to do this, there must be a disaster preparedness plan in place that involves multiple people in various roles.

Seismologists have recorded that most Oklahoma earthquakes generally strike within the 2.5 – 3.0 magnitude on average. While some have been recorded to spike up much higher which could potentially cause structural damage to homes. Earthquakes of large magnitude have the potential to create large-scale destruction to homes, which do not meet building code requirements for earthquakes of this magnitude. “It has implications for calculated risks of seismic hazard, and it will have an economic impact on the state if people have to start building to more stringent design standards (Brus).”

The San-Francisco earthquake caused quite a lot of damage in the area, but what is an earthquake? An earthquake is the movement of tectonic plates along a transform boundary and what plate is California sitting on? The Pacific Plate which is not connected to the North American plate and the plate boundary is a transform boundary. Earthquakes occur so often there that people say it is like a rainstorm that is ignored. The place where the Pacific Plate is grinding along with the North American Plate is called the San Andreas Fault. As stated before the earthquake had a magnitude of 7.8 which caused so much destruction a fire broke out. Nobody really knows where the fire started but it burned for 7 days and scorched over 500 city blocks leaving the once proud and powerful city into dust. The combination of the earthquake and fire is said to have killed “ Over 700 deaths by the earthquake and fire is now believed to be an understatement the total loss of life by a factor of 3 or 4.” (The Great 1906 San-Francisco Earthquake.)

This chapter provides an overview that describes the basic types of hazards threatening the United States and provides definitions for some basic terms such as hazards, emergencies, and disasters. The chapter also provides a brief history of emergency management in the federal government and a general description of the current emergency management system—including the basic functions performed by local emergency managers. The chapter concludes with a discussion of the all-hazards approach and its implications for local emergency management.

Editor’s Note: This Chapter is the continuation of an adaptation of a state plan for disaster preparation and response. In total, the original chapter comprises Chapters 1, 14, 16-18.

California is notorious for its wildfires. In the last two decades San Diego County has faced some of the most destructive firestorms in state history (Brainard, 2007). Ron Roberts, chairman of the San Diego County Board of Supervisors, describes the county’s disposition as, "We have a very dangerous, unpredictable situation. We have some of the highest temperatures, some of the driest landscape conditions, and some of the most powerful winds - all ingredients for a perfect firestorm (Pesce, 2007)." In 2003, San Diego County was overwhelmed by firestorms, including the Cedar Fire, and at that time it was the worst in state history. However, in 2007 San Diego was once again devastated by firestorms, but this time more mighty than the preceding (Ekard, Tuck, Jr., & Steffen, 2003). San Diego has had its fair share of practice at managing firestorm response actions. The 2003 firestorms proved that there were numerous inefficiencies within the county’s emergency response plan, while the 2007 firestorms emergency response revealed the lessons learned from 2003 and improvements implemented were effective. The threat of future firestorms in San Diego County are inevitable due to the continuing drought, Santa Anna winds, climate changes, and human behavior (Pesce, 2007). Having a well-constructed Incident Command System (ICS) and the trained personnel to execute its model is the most effective measure to mitigate the degree of life lost and property damage in a disaster incident.

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.

In order to survive during an earthquake, you must be very aware of how exactly to react and what to do in order to survive. The California Department of Public Health informs families to make a plan to evacuate their homes and find a safe place to go after the first sign of an earthquake (Earthquakes). This is the right thing to do, but people need to know where to go and how fast they need to act. Currently “California does not have an operational earthquake early warning system” (California Seismic Safety Commission) which could warn people when they need to evacuate before the earthquake even hits. I believe that the government of California needs to bring the early warning system back into their safety procedures. The government could also make clear where citizens from each county should go short term and long term in the case of an earthquake. Evacuation plans need to be made for when the earthquake is occurring when people need to find cover where nothing is going to fall on them. Plans for after the initial shaking need to be made as well, telling people to start heading inland toward surrounding states. This plan, however, requires the public to avoid driving over fault lines that could potentially move again. The San Andreas fault system is more than 800 miles long (Oskin), therefore people will need a set evacuation plan in order to know how to evacuate properly. The

My inference is that California is at a very high risk from earthquakes and needs better earthquake safety for buildings and houses. This is because California is located to be a fault line named San Andreas.The type of plate boundary that this fault is on is a transform tectonic plate.This fault line is lined up all around the coast of California and is the sliding boundary between the Pacific Plate and the North American Plate.Although.According to an article named the San Andreas fault by David K. Lynch “And despite San Francisco’s legendary 1906 earthquake, The San Andreas Fault does not go through the city. But communities like Desert Hot Springs, San Bernardino, Wrightwood, Palmdale, Daly City, lies squarely on the fault and are sitting

California is due to be hit by an earthquake with an high magnitude of 8.0 comparable to the 1906 San Francisco 7.6 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.
