The media normally reports only the major earthquakes that occur around the world, even though there are dozens each day, many of which are insignificant and cause no damage. The earthquake that struck Christchurch in New Zealand on Wednesday 22nd February 2011 however was just one of a large number of aftershocks that had hit the area since a large earthquake on 4th September 2010.
Dozens of earthquakes occur daily around the world, but we only ever hear about the big ones, those that cause major damage, destruction or loss of life. It does seem though that in the last several years, there have been more than the average number of major earthquakes, as well as some significant volcanic activity around the world. Should we be concerned about this? Is it related to Global Warming or Climate Change? Is the earth going through some changes that could bring about the end of the world as we know it?
