Huh?
In Japan during the 2011 earthquake and tsunami? Radiation exposure estimates now available
The Pentagon says that none of the nearly 70,000 members of the DoD-affiliated population (service members, DoD civilian employees and contractors, and family members of service members and civilian employees) who were on or near the mainland of Japan between March 12 and May 11, 2011, are known to have been exposed to radiation at levels associated with adverse medical conditions.
East Coast earthquake created a ‘new normal'
The quake was centered 3 to 4 miles beneath Mineral, a town of fewer than 500 people about 50 miles northwest of Richmond. Yet it was believed to have been felt by more people than any other in U.S. history.
Last Year’s Quake Shook Up Virginia Nukes
It was the first time ever in this country that a nuclear power station had gone through an emergency shutdown because of an earthquake. In this case it was a rare 5.8 magnitude seismic event with an epicenter a few miles away that ruined Louisa County school buildings, cracked the Washington Monument and shook the North Anna beyond what it was designed to deal with.
Why quake forecast maps often fail
Three of the largest and deadliest earthquakes in recent history occurred where earthquake hazard maps didn’t predict massive quakes, scientists say. A combination of bad assumptions, bad data, bad physics, and bad luck is why hazard maps have failed to predict three of the largest and deadliest earthquakes in recent history.
Earthquake Damage: Are Bad Maps to Blame?
A new study argues that earthquake-hazard maps didn't give engineers and seismologists a full picture of several recent quakes' dangers.
Study links fracking and earthquakes
In hydraulic fracturing, or fracking, millions of gallons of water, mixed with sand and chemicals, are injected into rock thousands of feet underground to extract natural gas. Frohlich said the most likely explanation for the quakes is that once injected, the fluids apply pressure to faults in the area and unstick them.
Fukushima Hangs by the Devil’s Thread
The molten cores at Units 1, 2 & 3 have threatened all life on Earth. The flood of liquid radiation has poisoned the Pacific. Fukushima’s cesium and other airborne emissions have already dwarfed Three Mile Island, Chernobyl and all nuclear explosions including Hiroshima and Nagasaki.
But at Unit 4, more than 1500 rods remain suspended in air. Called “a bathtub on the roof” by CNN anchor Jon King, the damaged pool teeters atop a building decimated by seismic shocks and at least one hydrogen explosion. The question is not if, but when it will come crashing down.
