Technology consultant Larry Park, the author of Forbidden Secrets of the Earthquake Revealed(1), discussedvolcanic dangers he believes are present in America and particularly in the Northwest, during the first hour on Friday. Through testing with his unique technology, Park has concluded that monstrous pressures are building up underground and could cause volcanoes, such as the one at Yellowstone Lake to blow.
Should such an event occur at this location, magma would shoot up thirty miles into the air, and he said, it would be one of the "loudest explosions mankind would ever hear," a sound literally heard around the world.
Not only would large amounts of ash be sent up into the stratosphere, but a 75 mile area surrounding the volcano would be devastated, Park warned. For more details about his theories read his article(2) published on yowusa.com.
