When Newberry Volcano south of Bend last erupted 1,300 years ago, gas trapped in sticky magma exploded from the caldera south of Bend, flinging pumice and ash more than 3,000 feet up into the air. As the volcanic gases settled down, flows of lava oozed out, quickly cooling into the glassy Big Obsidian Flow.
About 7,000 years ago, magma spread north from Newberry through a crack in the rock, erupting to form the Lava Butte cinder cone.
And with the magma still heating rocks under Newberry Volcano, geologists expect more eruptions to shake the area in the future.
"It's still hot under there," said Julie Donnelly-Nolan, a research geologist with the U.S. Geological Survey's Volcano Science Center in Menlo Park, Calif. "We have no reason to believe it's finished."
Because of this, the USGS is planning to add eight seismic monitoring stations next summer on Newberry Volcano, which the agency classifies as a "very high threat."
Comment: An excerpt from Fire and Ice: The Day After Tomorrow written by Laura Knight-Jadzyck in 2007:
"What is important is that there IS a heating up of the planet, a Global Warming, which is causing a lot of ice to melt. It is also causing a lot of evaporation which then falls as snow in certain areas, and this put pressure on the ice sheets and squeezes them outward so that they actually melt faster around the edges. This adds a LOT of fresh water to the oceans. In the Antarctic regions, it may not be so bad, but in the Arctic, it is a building cataclysm.
The implications are so huge that it is really no wonder that the Bush Reich and others of the ruling elite are trying to shush it up and convince people that it's just going to get hotter and we all have to make sacrifices to try to slow it down. As if! Bush is certainly right when he goes his merry way acting as if Global warming is nothing. He might as well because he, and the rest of them, know that there is nothing that anyone can do about it to stop it. That's a fact. And so, they continue to do the one thing that they believe will save their own skins: continue to follow the plan of imposing total control over everyone and everything so that when the disasters fall fast and hard - as they will - the masses will be controllable. And it certainly doesn't hurt to kill off as many as they can get away with killing in advance; that many fewer mouths to feed, doncha know?
In short, the economic, political and national security implications of sudden cataclysm are what is driving the political machine these days. Britain is headed for a climate worse than Alaska's. And it could be here sooner than anyone expects."
