Few can doubt the enormous impact of a 7+ magnitude earthquake on health and regional infrastructure. In the past six months, there have been 13 earthquakes around the world of at least 7.0 or more on the Richter scale. Earthquakes above 5 are up 125% compared to their average frequency over the last hundred years.
Magnitudes between 5 and 7 affected other countries such as Spain, Canada (Ontario-Quebec Border), China (Southern Qinghai) and the United States (California, Alaska).
Earthquakes between 5 and 7 can cause major damage to poorly constructed buildings and may even damage well designed buildings over small regions. They can be destructive in areas up to about 160 kilometres (100 mi) across in populated areas.
Earthquakes above 7 can cause serious damage over larger areas and may several hundred miles across. The earthquake in the Maule Region of Chile in February, 2010, was equivalent to a the energy yield of a 238 TNT megaton explosion.
Statistics compiled by CRED show there were 22 earthquake disasters in 2009, compared with an annual average of 30 between 2000 and 2008.
The number of earthquakes greater than magnitude 4.0 in Southern California and Baja California has increased significantly in 2010. There have been 70 such quakes so far this year, the most of any year in the last decade. And it's only April. There were 30 in 2009 and 29 in 2008.
Seismologists said they are studying the uptick but cannot fully explain it. Major earthquakes tend to occur in cycles, and experts have said the region in recent years has been in a quiet cycle when it comes to sizable temblors.
The data used in the analysis below were collected from the USGS (United States Geological Survey) as of June 30, 2010 and going back to to the year 1900. The number of earthquakes were averaged since 1900 in each magnitude range (5.0 to 5.9, 6.0 – 6.9, 7.0 to 7.9, and 8.0 to 9.9), and also averaged on the same data over the last 10 years. The data was then compared with current earthquake statistics so far in 2010.
Earthquakes of magnitude 5 – 5.9 have increased by 27 percent (127% of normal) compared with same range of earthquakes over the last 10 years.
Earthquakes of magnitude 5 – 5.9 have increased by 49 percent (149% of normal) compared with same range of earthquakes since the year 1900.
Earthquakes of magnitude 6 – 6.9 have increased by 26 percent (126% of normal) compared with same range of earthquakes over the last 10 years.
Earthquakes of magnitude 6 – 6.9 have increased by 36 percent (136% of normal) compared with same range of earthquakes since the year 1900.
Earthquakes of magnitude 7 – 7.9 have increased by 39 percent (139% of normal) compared with same range of earthquakes over the last 10 years.
Earthquakes of magnitude 7 – 7.9 have increased by 22 percent (122% of normal) compared with same range of earthquakes since the year 1900.
Earthquakes of magnitude 8 – 9.9 have equaled the average of 1 (100% normal) compared with same range of earthquakes over the last 10 years.
Earthquakes of magnitude 8 – 9.9 haveequaled the average of 1 (100% normal) compared with same range of earthquakes since the year 1900.
The biggest problem, according to geophysicists is that the tectonic plate shifts have increased the number of serious earthquakes in the past one-year an enormous amount and the rate is exponentially increasing. Scientists are blaming the Polar reversal and these will continue till 2012.Very rarely the Sun and the Earth simultaneously reverses polarity. That is exactly what is happening now. When this happens catastrophes happen in the earth. If history is a guide of anything, these earthquakes and volcanoes will continue to increase till 2012.
Periodic moderate earthquake reminds of a systematic tectonic disturbance in Northern Sumatra for the last one year. Many now are predicting that either a major cataclysmic event has been avoided or initiated. The same is happening in Western and Northwestern America, More than 600 small earthquakes have been registered in these areas.
According to scientists, all hot spots – Sumatra. Yellowstone and many others are showing signs of extreme disturbance – even harmonic tremors. "We are really sitting in front of a series of very catastrophic series of earthquakes all over the world."
Some conspiracy scientists are even attempting to document evidence to prove that at least some of the smaller earthquakes are the result of covert military experiments using High-Frequency Active Aural Research Program (HAARP) funded by the U.S. Defense Department and the University of Alaska.
