Answers
Answer:
The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes.
(a) 5.0 - Getty Images A moderate earthquake registers between 5 and 5.9 on the Richter scale and causes slight damage to buildings and other structures. There are about 500 of these around the globe every year. An earthquake of magnitude 5.5 struck the border between Quebec, seen here, and Ontario in June 2010.
(b)6.0- Generally, earthquakes of magnitude 6 and above are the ones for concern. When nearby, they can cause shaking intensities that can begin to break chimneys and cause considerable damage to the most seismically vulnerable structures, such as non-retrofitted brick buildings.
(c) 7.0 - Can cause serious damage over larger areas..
