Earthquakes
What patterns to you see in the distribution of earthquakes across the continental United States
The most obvious patterns show that more severe earthquakes are notably seen in the western part of the United States along the coastline of California, Washington, and Oregon. The severity tends to ease as you look towards the center of the United States until you reach the New Madrid Seismic Zone in the Central U.S. Here you notice the severity in a smaller area with no coastal fault line. The most severe activity is near the fault lines and eases as you move away from them.
Locate your home on this map and make a note of the relative risk to you by indicating the color where you live. The USGS also reports on earthquakes around the world.

I currently reside in eastern Iowa and am at minimal risk for an earthquake as I am in the blue area which shows one of the lowest areas for shaking activity at 4-8 % g (g is the acceleration of a falling object due to gravity).
What patterns do you see in the distribution of earthquakes around the world
The most obvious pattern to me in the distribution of earthquakes around the world is the large amount of activity around islands and coast lines, and the minimal amount of activity on any large land mass. Alaska is the most earthquake-prone state and one of the most seismically active regions in the world. Alaska experiences a magnitude 7 earthquake almost every year.
Click on one of the earthquakes on the map and make a note of its magnitude and region. Would you be willing to live in one of the red areas on the map Explain.
Since I have no desire to live outside of the United States I clicked on the Arkansas area (I have family there) with a 2.9 magnitude. I do not feel as if I would live in the red area. Although historically there have not been any large magnitude earthquakes in this area in a very long time, there is potential for a large earthquake to happen in the next 50 years according to the map at the following site: http://earthquake.usgs.gov/eqcenter/recenteqsww/
If you and your family were forced to relocate to a red area, how could you use the USGS resources on earthquake readiness (http://earthquake.usgs.gov/learning/faq.phpcategoryID=14) to help your family prepare themselves
If we were forced to relocate to a red area, the USGS resources on earthquake readiness would be helpful in numerous ways. The site answers common questions, gives a list of supplies that may be needed, how to plan ahead for an earthquake, what should and should not be done during an earthquake, what can be expected of your home and how to identify it, as well as what should be done after an earthquake. Knowledge of safety is a major factor in these potentially dangerous areas.
Examine the list of the most destructive earthquakes on record:http://earthquake.usgs.gov/regional/world/most_destructive.phpWhat are the two most recent earthquakes on this list What does this list tell you about the power of science to control or predict earthquakes
After examining the list of the most destructive earthquakes on record, I found that the two most recent earthquakes were in 2010 and 2008. Although science is a powerful tool in our world, it is unable to predict or control earthquakes. What this list does tell me is that tsunami??™s caused by earthquakes are somewhat predictable, therefore it is possible to warn people of possible catastrophe??™s. Since earthquakes are unpredictable there are often very large numbers of fatalities because of the inability to warn, and other possible effects the quake can cause, such as landslides and tsunamis.
Even though science cannot predict or prevent earthquakes, what seismological tools do we have to sense the planets rumblings What events do you think might have encouraged the development of these tools
Earthquakes are recorded by instruments called seismographs. The recording they make is called a seismogram. The seismograph has a base that sets firmly in the ground, and a heavy weight that hangs free. When an earthquake causes the ground to shake, the base of the seismograph shakes too, but the hanging weight does not. Instead the spring or string that it is hanging from absorbs all the movement. The difference in position between the shaking part of the seismograph and the motionless part is what is recorded. We also use Global Positioning System satellites, and the Internet to tie it all together.
How is this kind of geological energy different from biological energy (such as the calories creatures get when they consume food) How are they the same
Geological energy appears in nature in many forms and one of its conversion phenomena is an earthquake. Existing below the earth??™s crust in the form of movement of tectonic plates, the sudden release of energy in the earths crust leads to seismic waves or tremors. The tectonic energy is released in the form of mechanical energy and its amount depends upon the strain and mass of area involved and acceleration of waves. It doesn??™t exist in biological or living organisms.
Biological energy originates from the sun and is stored in plants and animals as chemical energy. Plants convert solar energy into chemical energy and animals get it from plants. It is stored in chemical bonds in stable molecules like carbohydrates and thus a form of chemical energy. It exists mainly in the biological or living organisms and this energy is important for survival for living organisms.
Both are a form of energy and involve exothermic processes. Both also cause some action to occur during their transfer from one entity to another or their conversion to other forms of energy. Both exist in our solar system and the source of both is mainly a heavenly body, the sun in the case of biological energy, and earth in the case of earthquake geological energy.
