The effects of an electromagnetic pulse (EMP) attack in the form of high-altitude nuclear weapons and geomagnetic disturbances (GMD) from coronal mass ejections have been studied by government and private organizations. The similar consequences of both can be devastating. As much as 90 percent of the U.S. population may not survive a “grid-down” environment lasting a year or more -- and the National Academy of Sciences projected a 4 to 10 year recovery period for a “severe” event affecting a large regional expanse. (Note: Congress must appropriate funds and change the regulatory authority and expertise of the Federal Energy Regulatory Commission for any meaningful changes to take place.)

(INTELLIHUB) — In what may prove to be bad news for a one-thousand mile swath of the United States, the Yellowstone supervolcano may be on the brink of a massive explosion that would be categorized as an extinction level event (ELE).
In fact, recent reports suggest that ancient Helium4 gas has breached the surface layers of Yellowstone’s crust,escaping into the atmosphere. Now couple that with the recent and abrupt ground level rise in the park–and we may be looking at a spell for disaster…..
Later in the newscast the popular physicist points out how a 1000-mile ring of the U.S. would likely be destroyed if the supervolcano actually went. And as scary as that seems to some, we are actually quite overdue for the big one. In fact, the last Yellowstone eruption was thought to have happened around 630,000-years ago, meaning we are 30,000-years overdue for a total explosion…..
