Despite spreading contamination in America, the Environmental Protection Agency (EPA) stopped measuring radiation levels in eight of its 18 monitoring stations, including California, Oregon and Washington because readings are getting too high.
In addition, Obama's EPA may substantially increase allowable radiation amounts called safe in food, water and the environment. New guidelines will also permit much laxer long-term cleanup thresholds, greatly endangering public health.
Five Types of Human Activity Causing Quakes
(1) Damn construction
Since water is heavier than air, the crust beneath it is greatly stressed, easily setting off mostly moderate shocks. University of Alaska seismologist Larry Gedney explained:
"Since the (Hoover Dam) reached its peak of 475 feet in 1939, the level of seismicity has fluctuated in direct response to water level. None of the shocks have been particularly damaging - the largest was about magnitude 5 - but the area had no record of being seismically active."
According to geophysical hazards expert Christian Klose, dams trigger about one-third of human-caused quakes. No wonder given their global proliferation, 845,000 according to Discover magazine, including 80,000 in America. Hoover Dam is the largest, storing 1.2 trillion cubic feet of water. China's Three Gorges Dam is the world's largest, holding back 1.4 trillion cubic feet. In 1967, western India's Koyna Dam may have caused a 7.0 magnitude quake. If so, damns in seismically active areas may be much more destructive than believed.
