1. Earthquakes occur in various part of United States. The earthquakes that occurred across the country ranges in magnitude and the date of occurrences. Earthquake with highest magnitude that was recorded in history occurred in Alaska while the one with lowest magnitude occurred in the Idaho area of United States. From the national seismic hazard maps (2008) shows that certain area of united states are more prone to attack while some areas have moderate probability and while some region are at a lesser probability of occurrence.
Western states such as California, Nevada, Oregon and Arizona are at higher risk of earthquakes while regions such as South Dakota, Wisconsin and Minnesota are at the lowest risk of earthquake occurrences. Those at moderate risk include Oklahoma, Arkansas and Missouri. The relative probability risk of earthquake occurrences ranges from the low risk central and northern region to the moderate region of some of the eastern states to the highest risk of the western states or region. 2.
On the map, the color of Houston Texas is relatively grayish showing that this region is at a lower risk or probability of earthquake occurrence within the next fifty years. 3. Data from the USGS in regards to the latest earthquakes in the world (showing that of the past 7 days in terms of their magnitude and the date of occurrence) indicate that distribution of earthquakes around the world is not even. The map shows 208 different earthquakes in relation to the time of occurrence and their magnitude.
Regions such as the western part of the USA, the area of Alaska, Northern part of South America, some northern and eastern parts of Australia and the southern part of Asia shows earthquake experiences that are within the range of 5-7 magnitude and they can be felt. Around the some part of central Asia there are some scattered distributions of earthquakes which are of lower magnitudes and most are not usually felt. 4. The details of the earthquake that occurred on the southern American continent are as follows; magnitude 5.
0, location 12. 100 degree S, 75. 338 degree W, PERU region with location uncertainty of Horizontal +/_ 13. 5 km (8. 34); depth +/- 3. 4km (2. 1 miles). The earthquake occurred on Saturday, August 01, 2009 at 23:07:04 UTC. 5. I’m never going to be willing to live in those regions with higher probability of earthquake simply because “prevention is better than cure”. Having considering various social, environmental and economic impacts on the lives of people being affected by earthquake, I will never consider living in such red regions. 6.
In situation where I’m forced to live in such areas I will consider some of the precautions that can help me and family to prepare and prevent ourselves from being affected by such disaster. Some of what I can do to help my family prepare for such situation includes the use of the USGS resources which helps peoples and family prepare for earthquake events. The resources that have been found to help in such situations are categorized into the following; • How can I plan ahead for an earthquake • What emergency supply do I need • What to do during an earthquake
In order for me to help my family prepare for such an event in the future if eventually I was forced to relocate to the red areas are as follows; I will make sure each of my family member knows what to actually do no matter wherever they are during an earthquake such as establishing a meeting point where we can reunite after afterwards, find out the preventive measure or plan by the children schools for an earthquake attack, and remember that transportation may be disrupted during the event hence there is a need to keep supplies whenever there is chance to do so.
I will also try as much as possible to prevent any form of fire outbreak that might worsen the situation. This will be achieved by turning off all the units that can lead to leakage and subsequent fire incidence. I will immediately locate the fire and police station or any available emergency facilities for any rescue. I will also talk to my neighbor in preparedness for an earthquake so for us to know what we can do to help each other during and after an attack. I will also take special training in cardiopulmonary resuscitation and first aid processes. 7.
The list of the most destructive earthquakes that occurred in the world are the earthquake that occurred in Pakistan in 2005 and that which occurred at Eastern Sichuan, China in the year 2008. The earthquake at Pakistan recorder about 86000 while that of the china recorded about 87,587 deaths. There are several missing bodies during both events and thousands of people became homeless after the events. This list of most destructive earthquakes shows that science is yet to be able to predicts or control earthquake because if they have the power or knowledge to do so, we ought not to have massive destruction like the two most recent earthquakes.
8. Seismograms is the seismological tool that scientist has been able to create to detect rumbling of the earth which usually indicate events going on within the earth layers and also the magnitude of a particular earthquake. What can be consider to be the main motivation for developing seismograms is the understanding of what lead to earthquakes that is the faults and the shakings that occurred within the ground which subsequently causes earthquake. They develop this tool so as to be able to detect this shakings and measure it magnitude. 9.
This geological energy is different from biological in the sense that movements of the blocks within the earth result in the conversion of energy caused by the friction into the heat energy which subsequently contributes to the earthquakes while biological energy (which is measured in terms of calorie ) are usually derived from the chemical energy and not the frictional energy. The two forms of energy are similar in the sense that they can be converted to heat energy. References Lisa,W. (2009). “The Science of Earthquakes”.
