Don’t panic! Preliminary data suggests earthquakes are indeed increasing worldwide

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)

Largest increase in 62 years: According to the Costa Rican Volcanology and Seismology Observatory (OVSICORI), after the magnitude 7.6 earthquake which occurred on September 5th, 2012, the country registered the highest level of earthquake activity it has seen in 62 years. The strongest earthquakes in Costa Rican history occurred in 1950 in Nicoya, with a 7.8 magnitude quake, followed by the 2012 earthquake that occurred in the same area, of a 7.6 magnitude. After the September 5th earthquake, OVSICORI reported 75 earthquakes that were felt by residents during the 4 months after the main event. 2010 saw a total of 6,245 earthquakes, in 2011 there were 5,483, and in 2012 the total was 11,049. –Inside Costa Rica

Japan shaking more: Japan had experienced a little over 3,000 noticeable earthquakes in 2012, nearly 60 percent of them aftershocks from last year’s massive tremor that devastated the country’s northeast, Japanese media reported on Monday. Quoting the Japan Meteorological Agency, the NHK broadcaster reported that a total of 3,134 quakes had been felt across Japan until Sunday (December 30) which is about 1,000 more than the annual average from 2001 to 2010. An analysis of seismic waves indicates that there were more than 10,000 noticeable quakes in 2011. While the number of quakes decreased from that of last year, seismologists continue to monitor frequent seismic activity. They urged people to be on the alert for possible strong quakes with a magnitude of at least 7 or those triggering tsunami. The March 11, 2011 quake and the tsunami it triggered had left more than 15,000 people dead or missing besides wreaking havoc in Japan’s northeast, including the meltdown at the Fukushima Daiichi nuclear power plant that leaked radiation forcing the evacuation of more than 160,000 residents. –RTT
