Epicenter and Magnitude of the Earthquake Assignment

Epicenter and Magnitude of the Earthquake - Assignment Example To locate the epicenter of the earthquake, the seismologists examine seismograms from three seismic stations. The seismologists measure the time interval of S-waves and P-waves in about 45 seconds and place the vertical lines at an interval of about 2 seconds. The measured S-P time interval will help to determine waves distance of travel from the focus to the station. It is paramount to note that the actual location of the epicenter is on the circle's perimeter to be drawn around the station. Therefore, to triangulate this position, there must be three seismic stations. A circle with an appropriate radius is drawn around every station and where the three circles intersect is the epicenter of the earthquake. Â  The seismologists use a well-known Richter scale to measure the magnitude of an earthquake. To determine the earthquake’s Richter magnitude, seismologists require one to know the surface the wave’s amplitude and the distance to the origin of the earthquake at the seismic recording site or location. The distance of the seismic recording and footage station from the epicenter can be determined by getting the time difference between the arrival of the P-waves and S-waves at the station. The difference is called S-P interval. The amplitude of the surface wave depends on the earthquakes magnitude and the distance between the epicenter and recording station. It is a measure of how many millimeters the ground will move at the recording station. The amplitude and S-P interval is then used to determine the Richter magnitude.

Economics and Government - Assignment Example Q4. Politics is as important as economics because it involves the allocation of scarce resources. I believe so because politics design systems that are used in the allocation of scarce resources (Roth 100). Q5. Targeting public transfer programs in the US affected public support for government redistribution by lowering public confidence. There was the observation that resources set aside for redistribution were being misused hence not benefiting the target public. Q6. Canada has income redistribution through minimum wages. Minimum wages target low earning individuals and reduce the gap between the rich and the poor. Minimum wages does not affect public support for government redistribution in the same way. This is because income redistribution has resulted in the public gaining confidence in the government since there is an improvement in living standards. Q7. Public insuring of healthcare expenditures in Canada has the effect of increasing support for government redistribution because it reduces the burden of paying for healthcare. The case is different in the US because the public bears the burden of covering healthcare costs. Health insurance represents a form of government redistribution because everyone is able to have access to healthcare free of charge at any public healthcare center (Mankiw 24). This is a big deal because a large portion of the population is unable to have access to healthcare services as a result of high costs. Q8. A decline in private sector unionization is an indication that the public has confidence in the government hence supporting government redistribution (Deming 11). In the case of Canada, declining private sector unionization has the same effect on public support for government redistribution. Q9. ‘Great Divergence’ refers to the process through which European countries overcame growth constraints to become the wealthiest nations
