Starting in January 2009, the USGS National Earthquake Information Center no longer locates earthquakes smaller than magnitude 4.5 outside the United States, unless specific information of that a earthquake was felt or caused damage has been received. http://earthquake.usgs.gov/earthquakes/eqarchives/year/eqstats.php

What is a Hurricane?
Hurricanes are large tropical storms with heavy winds. By definition, they contain winds in excess of 74 miles per hour (119 km per hour) and large areas of rainfall. In addition, they have the potential to spawn dangerous tornadoes. The

    First of all, gather all the materials that are required for the lab and setup accordingly for the lab. Place the ruler on the lab table so that 0 cm projects beyond the lab table. Measure the height from the free end of the ruler (bottom line of the ruler) to the floor and record the data in a table. Clamp a meter stick on the table horizontally such that 20 cm is projected beyond the table. Measure the height again from the free end of the ruler to the floor and record it. Attach a 1 kg load to the free end of the ruler and measure the height from the free end of the ruler to the floor and record the data. Repeat this same procedure for 30 cm, 40cm, 50cm, 60cm, 70cm, and 80cm. Remember to check the zero load height every time before putting on the load. Repeat the above procedure for second trial so that you can get more precise data for the experiment.…

    In general, the map that contained all the earthquake distributions mostly had shallow quakes spread around. Deep quakes on the map were a lot less common. I would estimate that about 85%-90% of the earthquakes were shallow quakes. There were only three earthquakes on the map that had a magnitude of 7.0 or greater. The earthquakes that appeared to have occurred along spreading zones made up about 80% of the earthquakes on the map. Earthquakes that have occurred in these areas generally have ocean ridges. The other areas where earthquakes happen are on subduction zones where there usually are ocean trenches and oceanic mountain ranges. About 13% of the earthquakes on the map occurred along subduction zones. Out of all of the earthquakes on the map, I would say that about twenty of the quakes do not appear to be associated with any active plate boundary. The most powerful earthquakes that were plotted on the map occurred along subduction zones. The deepest earthquakes on the map also occurred along subduction zones. The geological factors that might explain the different levels of earthquake activity seen in the Atlantic and Pacific Ocean basins is that in the Atlantic Ocean basin, there is a divergent spreading zone. On the other hand, the Pacific Ocean basin is on a subduction zone. Overall in the three-week period, the population centers that experienced the largest numbers of earthquakes were East India and Indonesia. The earthquakes that occurred in India and Indonesia were very well reported in the news because it caused deaths of more than 100,000 people and billions of dollars worth of…

    The Epicenter, location on the earths surface directly above focus, of the '64 earthquake is located in the northern part of the Prince William Sound; specifically 61.04º N- 147.73º W, approximately 75 miles east of Anchorage. The focus, or depth of the earthquake, is estimated at 25 miles below the epicenter. In general, the lower the earthquake occurs below the surface of the earth, the weaker it is; 25 miles is relatively close to the surface compared to most earthquakes that occur in…

    Today, over 1000 seismographs measure minute shaking over California, much of which goes unnoticed by human detection. This array of seismographs helped to develop a subsurface model of fault systems and an understanding of which faults potentially hold higher strain. This helps us understand which faults would be more likely to produce strong earthquakes, the relative probability of earthquake occurrence, and expected shaking. Unfortunately, the occurrence of earthquake detection is probabilistic in nature and therefore is limited to long-term predictions. This is similar to the 100-year flood. Scientists determine a 100-year flood based on historical records of flooding, but this doesn't stop two 100-year floods from happening back to back and then none for several hundred…

    A hurricane is a large, swirling storm with strong winds, that can blow up to 74 miles per hour or higher. Second, a hurricane is categorized by its wind speed using the Saffir-Simpson Hurricane Scale, the highest is a Category 5, which is 157 mph or similar, or close, to the speed of some high-speed trains. Third, hurricanes are named, because more than one may exist at the same time, names also make it easier to keep track of and talk about storms. In addition, NASA scientists collect information on clouds, rainfall, wind, and the temperature of the ocean's surface. Also, NASA is developing several ways to help scientists better understand hurricanes, one of them is the Hurricane Imaging Radiometer, it will be carried by an airplane or…

    The main shock of the Northridge Earthquake ruptured on a hidden fault approximately 18 Kilometers beneath the surface for roughly 8 seconds. The rupture proliferated upward and northwestward alongside the fault at around 3 kilometers per second. The resulting size of the rupture was between 15 and 20 kilometers and concluded at a depth of 5 to 6 kilometers. Unfortunately, the greatest seismic energy was directed toward the most populated areas in the northern regions of the San Fernando Valley.…

    Richter studied many earthquakes that occurred between 1900 and 1950. The largest had magnitude of 8.9 on the Richter scale, and the smallest had magnitude 0. This corresponds to a ratio of intensities of 800,000,000, so the Richter scale provides more manageable numbers to work with.…

    Abstract: How does the physical makeup and size of an organism relate to various activities an organism perform is a topic many people curious about. We wanted to find out if there was any relationship between the body size of woodlice and their speed. We hypothesized that the bigger woodlice have higher speed than smaller woodlice. We conducted an in-class experiment to test our hypothesis. We took ten woodlice and divided them into two groups: smaller and bigger woodlice. Each woodlouse was then let to run for 10 cm and time taken to reach the destination was recorded. Finally, when all woodlice completed running, we conducted a t-test. The value of ‘P’ from our test was 0.8956 which is larger than 5% level of significance. Since our value of P was larger than the 5% level of significance, we rejected our hypothesis and accepted the null hypothesis. The null hypothesis was that there is no relationship between the body size of woodlice and their speed. The findings from this experiment can be useful in determining and studying relationship between physical size and activities performed by many animals,…
