‘The Earth Has Experienced a Noticeable Increase In Seismic Activity and Intensity Over the Past Few Years’

“There are seismologists who believe that the earth has experienced a noticeable increase in seismic activity and intensity over the past few years. According to latest statistics from the United States Geological Survey, between 1986 and 1996, there were 15 earthquakes of magnitude 7.0 or greater. In the next 10 years, the frequency increased by more than six times. Even the rate of lesser magnitude earthquakes has increased. Around 120 earthquakes of magnitude 6.0-6.9 take place every year. And, in the last week alone, we have had six. At this rate, we would end up having almost three-times more earthquakes this year!

‘I don’t think anyone can explain why the activity has increased,’ says Segall. Several theories have been put forth to explain what is happening. Though most of them are no better than conspiracy theories, a few seem credible. One of the theories has to do with a meteor that has returned to the earth’s proximity and may be affecting its gravity balance. Another theory points to solar flares reaching the earth’s surface, thus affecting its electro-magnetic fields. And, of course, there are some who believe that the earth’s rotational axis has shifted, causing changes in climate, waves and gravity; this, according to them, has resulted in hurricanes, earthquakes and tornadoes.” Read more.

Killer earthquakes on the rise – “The last decade has seen an intensification in earthquake activities. The 2004 Sumatra quake in Indonesia, which registered 9.3 on the Richter scale, has triggered stress in many areas. The Sikkim earthquake could be a manifestation of this stress. Earthquakes, some scientists believe, are on the rise. The earthquake in Fukushima in Japan had a magnitude of 8.9 and was the largest in the recorded history of Japan. The February 2010 Chile earthquake registered a similar magnitude as the Japan quake while the January 2010 quake in Haiti had a magnitude of 7.0 on the Richter scale. Prof D.K. Paul, an earthquake engineer with IIT Roorkee, believes the pushing of the Indian tectonic plate under the Eurasian plate (at the rate of 5 cm per year) results in stresses which over a period of time, manifest as earthquakes.” Read more.
