The earth 's subsurface is broken up into a bunch of puzzle-like pieces. These puzzle pieces are called tectonic plates. The edge of the tectonic plates are called faults and this is typically where earthquakes occur. There are three types of boundaries that the pieces can have; divergent, convergent, and transform. Earthquakes occur at transform boundaries most often. At a transform boundary, the two tectonic plates “suddenly slip past one and other” and the energy creates ripples, called seismic waves, that are felt on the surface (Wald).
There can be three parts to an earthquake: the foreshock, the mainshock, and the aftershock. The foreshock and the aftershock are smaller than the mainshock but can still be powerful. Sometimes, there is not a foreshock, but there is always an aftershock. If the mainshock earthquake is large enough, then the aftershock earthquakes can “continue for weeks, months, and even years after the mainshock” (Wald).
A seismograph machine is used to record earthquakes. The machine has a “base that sets firmly in the ground and a heavy weight that hangs free” on a string (Wald). When the earthquake is in progress, the base of the machine shakes with the earthquake but the string absorbs all the movement and the weight remains still. Scientists use this data to figure out the strength of an earthquake and the epicenter. At this time, scientists are unable to predict...

...d ahead to recovery for many (Archives.gov).
The government stepped in and enacted a few different emergency appropriations. The city was forced to pay for “food, water, tents, blankets, and medical supplies in the weeks following the quake and the fire” that was started shortly after the quake (Archives.gov). The government also gave funds to rebuild many of the damaged and destroyed public buildings. But this was a good reaction to the earthquake.
I hope that if a big earthquake that the government and international aid will have the ability to reach as many people as they can. The ways that I am preparing for this earthquake is by finding my safe spot in my house and, most importantly, creating a survival kit. The devastation from the earthquakes inspire me to prepare as well as I can if any disaster strikes. I will be prepared if an earthquake strikes, will you?

- There are different types and causes of disasters; man-made, natural and a combination. Man-made disasters are caused by human error or human actions that cause harm to the environment, and people (Baack & Alfred, 2013). Natural disasters are caused by nature a hurricane for example; and a combination; NA-TECH (natural-technological) examples are earthquakes that cause structural damage such as a collapse of a bridge (Nies & McEwen, 2011). Communities must have effective emergency preparedness in place to reduce the causalities from a disaster.... [tags: man-made, natural, combination]

- Anatural disasteris a normal phenomenon of nature that affects the society and environment.A natural physical event that kills people (directly or indirectly) or exceeds local capacity to control damage or initiate recovery efforts The situation or event which overwhelms local capacity, necessitating a request to national levelfor external or international assistance. " This means that the situation or event overflows the capacity locally, showing that not only the In the case of the United States, assistance for extreme events is linked by law to the disaster declaration issued by the president....

- When looking through the notebook trying to find the subjects that I wanted to talk about I found two topics that I thought were the most interesting and that I understood the most. The first chapter that I thought was the most interesting to me was natural selection. I think it’s really interesting because it is so prevalent in our lives. There are two different parts of natural selection. There is natural selection itself and then there is also non-adaptive evolution. Natural selection deals with the change of allele frequencies because of the change in the environment.... [tags: Evolution, Genetics, Gene, Allele]

- All over this earth there are numerous types of Natural Disasters. They are the most powerful forces of nature, which cannot be prevented. They cause all sorts of devastating destruction. Our only hope is that we can avoid them and keep ourselves out of their pathway. They occur in all different parts of the world. There is not a part of the world that does not experience at least some type of natural disaster. Hurricanes, Tornadoes, Earthquakes, Tsunamis, Avalanches, Wildfires, Volcanoes, Floods, and Thunderstorms are the N.D.’s that will be focused on in this research paper....

- Earth has many natural disasters that affect billions of people every year. Whether it is hurricanes, torrential rain, snow storms, or even tornadoes. But there is a natural disaster which unlike the others, is unpredictable. Earthquakes, one of the most feared natural disasters can kill thousands and affect millions when they occur. They can also be a precursor to an even worse event, the tsunami. Tsunamis cause even more damage than earthquakes, and most of the time it is the cause for most deaths after an earthquake....

- Eli Roth once stated, “Natural disasters are terrifying – that loss of control, this feeling that something is just going to randomly end your life for absolutely no reason is terrifying. But, what scares me is the human reaction to it and how people behave when the rules of civility and society are obliterated.” I couldn’t agree more with this statement of his. Our world is full of dangerous conditions that can cause serious damage upon humanity. However, if one can learn to respond, rather than react, it could be the factor that saves lives....

- Natural Disasters Natural Disasters caused many people to have problems over the years and killed many people. There have been a tremendous amount of different disasters that destroy multiple things. We need to have more people that are willing to help, not just the people made, when a disaster strikes. We also need everyone to come together as “one” so we can make it through the problems. As a society, we need to make sure that we have government support, school emergency plans, community warning systems, and we need to know how much money the damage will cost....

- Through out the years a lot of the biggest natural disasters in history have happened in the past couple of years. In my opinion Global Warming has been a major part of these natural disasters. Global warming is caused by the increases of carbon dioxide, chlorofluorocarbons, and other pollutants that most of cars and mostly big factories release into the atmosphere. These are mostly the best reason why the temperatures around the world are drastically changing; most of the north and south polar are melting in record times due to the increase of greenhouse effect....

- Evolution can be defined as the process through which the characteristics of a species undergo changes over a number of generations through the process of natural selection. There are different mechanisms that try to explain the evolution process and these are mutation, migration, genetic drift and natural selection. However for natural selection and genetic drift to take place there must exist a certain type of genetic variation. To begin with natural selection can be defined as the process through which organisms that are better adapted to a certain environment survive and produce fertile off springs....

- The Design Argument is quite similar to The Cosmological Argument as it attempts to infer the existence of God, but instead of from the existence of the cosmos it is from a particular aspect or character of the world, namely the presence of order, regularity and purpose. Order, regularity and purpose are seen as marks of design, and the argument concludes that God must be the source of that design. There are various types of Design Arguments, with philosophers giving them different names but the two most well known are The Argument from Design and The Argument to Design....
