The state of Illinois isn’t necessarily concerned about the significance of earthquakes, but we are prepared. Illinois has safety plans for when an earthquake occurs, but considering the “highest magnitude an earthquake has reached in Illinois is 5.2 in 1987” (Stover and Coffman, 2014). “A Richter scale (rĬk´tər), measures the magnitude of seismic waves from an earthquake with 10 being the highest most damageful magnitude” (The Columbia Encyclopedia, 6th ed., 2013). We are not too worried about it reaching a higher magnitude to where the damage is outrageous.
One of the largest earthquakes that happened in Southern Illinois was on May 26, 1909. This earthquake stretched over 500,000 miles meaning the people of Wisconsin and Iowa also felt the rumble. Chicago buildings were becoming unstable which gave citizens the thought the walls were going to collapse (N.A, 2007). Panic arose among the civilians, but no severe injuries were reported that were results from the earthquake. As you can tell, earthquakes aren’t a main problem in Illinois. Anything can happen though, so it is not l...
Setting in “An Occurrence at Owl Creek Bridge" is a mutable component and known as one of the most imperative indicators in the text to direct the reader towards how it should be perceived and what is happening. Based during the Civil War the environment was set in occupied Federal Army territory where, “a lieutenant stood at the right of the line, the point of his sword upon the ground, his left hand resting upon his right.” (Bierce 399). The function of time in “An Occurrence at Owl Creek Bridge" both creates positives and negatives that define the story as realist that describes moments with genuine detail, taking many paragraphs to relate a single second. Such as the moment, “ [Farquhar] looked a moment his “unsteadfast foot,” then let
Tectonic plate movement can occur as close as two and up to 450 miles below the Earth’s surface. According to the Indiana Geological Survey, Indiana’s fault lines are further underground than those in California and Alaska, causing more minor quakes in the Midwest. However, Hoosiers should heed the recent earthquake as a warning for future quakes. Earthquakes can and do happen in Indiana, and almost anywhere else in the world. This is the one natural disaster that people cannot avoid no matter their location on Earth. And, being unprepared can have devastating results.
In 1910 a series of fifty-two earthquakes struck Arizona between September 10th-23rd and it caused much of the Flagstaff residents to flee the area as even strong households cracked and chimneys crumbled. The fifty-two earthquakes were all light-shock earthquakes with magnitudes between 4.0-4.2 that came right after another. If only one earthquake occurred in that timespan then it is likely that only objects would be knocked from shelves but no damage would be done to infrastructure, but the earthquakes happened right after another causing significant slight
On February 4th 1975 in Haicheng China there was a magnitude 7.5 earthquake. Over a period of months there were changes in elevation in land, ground water and unusual animal behavior which are all precursors to an earthquake. Days before the 7.5 magnitude earthquake there were foreshocks that triggered an eviction warning that effectively saved over 150,000 lives or injuries. This is a pro as this forecast saved thousands of lives and had the people of this area (knowing this was a place of seismic activity) took precautions, like that of earthquake resistant buildings, evacuation points, preparing disaster supplies among other preparations the following may not have happened or would have been less of a disaster.
I think being prepared and educated will save many lives if and when we get the big one in the Cascadia region.

Earthquakes in California are certainly not a surprise. What is a surprise is their unpredictability and randomness. Geologists say there is roughly a 50 percent chance that a magnitude 8 or more quake will hit the Los Angeles area sometime over the next 30 years. And, over the past twenty years, the Los Angeles area has witnessed several earthquakes, and in particular, two that were quite devastating; the 1971 San Fernando earthquake, and the January 17, 1994, Northridge Earthquake. Given the certainty that earthquakes will occur, they still seem to come as a surprise, and leave many communities unprepared to deal with their aftermath.
1906 San Francisco Earthquake Jared E. Gatchalian San Jose State University. 1906 San Francisco Earthquake The 1906 San Francisco earthquake was one of the largest earthquakes in the United States. Even though it only lasted less than a minute, the damage and aftermath of the earthquake were disastrous. These damages were not just from the earthquake, but also from other hazards that occurred because of it. It also had a huge effect on the people living in San Francisco.
Boom! Crash! Sound echo everywhere. People scream all around you. A deadly 7.1 magnitude earthquake has just hit your town. On October 14, 2013 this happened in the Philippines (B-Essay). There were 3,512,281 affected individuals and 36,645 houses damaged (Doc. D). 39 roads and 18 bridges were in disrepair (Doc. D). People respond in certain ways after a natural disaster. They band together and react with Red Cross and government, Evacuation centers, and Gathering supplies.
The 1906 San Francisco Earthquake hit the Northern California coastline. The San Andreas fault shook 296 miles of the coast causing major damage throughout San Francisco, destroying about 80% of the city. Fires broke out throughout the city that lasted for several days. This was one of the worst Earthquakes recorded in history, killing 3,000 people.("The Great 1906 San Francisco Earthquake")
Hazards pose risk to everyone. Our acceptance of the risks associated with hazards dictates where and how we live. As humans, we accept a certain amount of risk when choosing to live our daily lives. From time to time, a hazard becomes an emergent situation. Tornadoes in the Midwest, hurricanes along the Gulf Coast or earthquakes in California are all hazards that residents in those regions accept and live with. This paper will examine one hazard that caused a disaster requiring a response from emergency management personnel. Specifically, the hazard more closely examined here is an earthquake. With the recent twenty year anniversary covered by many media outlets, the January 17, 1994, Northridge, California earthquake to date is the most expensive earthquake in American history.
The Great Kanto Earthquake also known as the Tokyo-Yokohama Earthquake of 1923 hit the metropolitan area of Kanto on September 1st, 1923 around 11:58 pm. It was a 7.9 on the Richter magnitude scale, killing over one-hundred and forty thousand people due to its high magnitude and the time it happened. The earthquake struck around lunch time, when many Japanese people were at home cooking at their charcoal or gas fueled stoves. At the moment the earthquake hit, it knocked down buildings that caught flames from the stoves that fell over, enflaming the city. The fire was swept up and able to spread due to the gusts of wind that occurred for two days afterwards, resulting in firestorms. Charles Blauvelt experienced the ordeal of the fire describing the flames as “[covering] the whole city [as they] burned all day and night.” In addition to the firestorms and the earthquake itself, there was a shock because of all the fallen debris which triggered tsunamis to fill and flood Japanese cities. These tsunamis, that were about thirty feet tall, destroyed central Tokyo and immensely added to the death toll.

Thousands of people have experienced an earthquake at one point in their life. An earthquake can be a type of stressor. This type of stressor is called a cataclysmic event. These events are “strong stressors that occur suddenly and typically affect many people simultaneously” (Feldman, 2010). Though some might think all kinds of stress lingers, but in these cases they usually don’t. In most cases it causes relief because people would believe that the worst has already happened and so they go on with their day with possibly even less stress. For example if I so happened to be shopping at the mall while my mom was at work and suddenly I felt a strong earthquake, I would begin to stress about the fact that my mom works in a large building nearby. Then I would do anything I can to get in contact with her to find out if she is well and unharmed. Then I would feel relieved to know that she is fine.
The death toll climbs to over 10,000 and is still rising (Branigan 2). The disaster in Japan began without warning on Friday March 11, 2011 at 2:46pm with a 9.0 magnitude earthquake, the strongest ever recorded in the country (Fackler 3). A massive thirty-three foot high tsunami, generated by the earthquake, swept over lands in northern Japan, taking objects and debris with it. To make matters worse, the tsunami caused the cooling systems at several nuclear power plants to fail. The disaster in Japan was a tragic event, and it had a plethora of causes and effects.
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
