December 31, 2012 – EARTHCHANGES – In recent weeks, worldwide earthquake data indicates an increase in the magnitude and a significant increase in the frequency (magnitude 5.5+) of earthquakes. Current graphs clearly show an alarming worldwide trend of increasing earthquake strength and frequency. These results are in agreement with the USGS statistics page, which shows an increase in the frequency of stronger earthquakes (M 5.0+). These trends also show that the depth of earthquakes has diminished, they occur closer to the Earth’s surface. Shallow earthquakes occur along fault lines and are due to the accumulation of stress. Earthquake waves can also propagate far enough to trigger other earthquakes; this may explain the noted increase in earthquakes. Certain scientists have stated that the increased frequency of earthquakes is due to the increased number of detection instruments installed worldwide. This would cause more sensitive earthquakes to be measured. However, these graphs show an increase in stronger earthquakes; it is also important to note that the earthquake Richter scale is base-10 logarithmic. The fact that the world’s population has increased doesn’t help, more people are affected by these events. There is increased media availability and attention. However, due to recent events, it is now easy to convince even the average person, that there are more and more strong earthquakes occurring worldwide. –Guardianlv (excerpt)
