"People nearly 900 miles away felt a magnitude-5.2 earthquake that shook southern Illinois early Friday, according to the U.S. Geological Survey.

Welcome to ATS, By the way you posted in the wrong forum but don't worry its not the end of the world. It happens to alot of people on here.

It has a long history of earthquakes, including some of the largest in modern Midwest history:
_2002, a magnitude 5.0 quake in far southwest Indiana causes little damage.
_1987, a magnitude 5.1 quake near Olney in southeastern Illinois leads to scattered and minor damage.
_1968, a magnitude 5.3 quake in southern Illinois causes damage across the region, and kills a St. Louis teenager who was struck by debris falling from a building. It is Illinois' largest modern quake.
_1909, a magnitude 5.1 quake near Terre Haute, Ind., leads to minor damage. It's the largest quake in modern Indiana history.
That 600 km radius around the caldera will experience total devastation. The next 600 km out may receive as much as 5-10 feet of ash, depending on wind direction. The thickness of ash will decrease away from the super-volcano, but will reach the crop belt in the Midwest (Missouri, Iowa, Kansas, Nebraska, etc.), destroying most of the fertile croplands of the United States. California will be hit hard by falling ash, with its central wine valley severely damaged (the French will love it). Agriculture will have to shift east of the Mississippi for years. The Garden State will once again live up to its name.
In northern Idaho you will have to contend with several feet of ash and isolation. Roads will be closed. Power will be out. Phones will be out. Communication will depend on Ham radios and local stations that have generators. Rescue will take weeks or months. Some areas will never see rescue teams. The survivalists will be best prepared to make it through the difficult months following the eruption. Make new friends. Have plenty of dust masks on hand, because you cannot breath any airborne ash if you want to avoid lung disease. It's what caused mass kills of plains animals 12 million years ago, resulting in extensive bone beds beneath the ash. Drinkable water will sell at the price of gold.

Okay! Lately we all been seeing a lot of Quake activity in the Mid-west and South west of the U.S. Their have been 100's of aftershocks reported. Now what I'm concerned about is "Yellow Stone AKA Super Volcano ready to blow any day now" Historically erupts every 600,000 yrs and were over due by like 30,000 yrs or so.

Oh, and apex -- the vid states 600,00 years.

Anyways i think the volcano will erupt soon but not too soon. Maybe an earthquake might trigger it. But that might come later in years. But when that happens most of America will be destroyed and our climate will be messed up and we will have to find some other place to live.
i do believe that something HUGE will happen 2012.

Satellite images acquired by ESA's ERS-2 revealed the recently discovered changes in Yellowstone's caldera are the result of molten rock movement 15 kilometres below the Earth's surface, according to a recent study published in Nature.
Using Synthetic Aperture Radar Interferometry, InSAR for short, Charles Wicks, Wayne Thatcher and other U.S. Geological Survey (USGS) scientists mapped the changes in the northern rim of the caldera, or crater, and discovered it had risen about 13 centimetres from 1997 to 2003.
ESA satellite reveals Yellowstone's deep secret
Yellowstone, like the Hawaiian Islands, is believed to lie on top of one of the planet's few dozen hotspots where light, hot, molten mantle rock rises towards the surface. The Yellowstone hotspot has a long history. Over the past 17 million years or so, successive eruptions have flooded lava over wide stretches of Washington, Oregon, California, Nevada, and Idaho, forming a string of comparatively flat calderas linked like beads, as the North American plate moves across the stationary hotspot. The oldest identified caldera remnant is straddling the border near McDermitt, Nevada-Oregon. The calderas' apparent motion to the east-northeast forms the Snake River Plain. However, what is actually happening is the result of the North American plate moving west-southwest over the stationary hotspot deep underneath.

Morgan, representing both the USGS and Yellowstone Volcanic Observatory, is in the process of mapping the lake floor with seismic reflection images. She uses a sonar system that emits sound waves. Morgan has taken 240 million soundings in the last four years...
"We're thinking this structure could be a precursor to an hydrothermal explosive event," Morgan said last week. "But we don't think this is a volcano."
