Earthquake Booms, 'Seneca Guns', and Other Sounds - Earthquake "booms" have been reported for a long time, and in the US they tend to occur more in the Northeastern US and along the East Coast. There have been many reports of "booms" that cannot be explained by man-made sources. No one knows for sure, but scientists speculate that these "booms" are probably small shallow earthquakes that are too small to be recorded, but large enough to be felt by people nearby. In New Madrid, Missouri, there are accounts of "artillery-like" sounds that were said to have occurred before or during the New Madrid earthquakes of 1811-1812. [Mystery booms coming from deep in the plate boundary were reported in Indonesia for many months before the December 2004 quake and tsunami.]

Meteors exploding in the atmosphere are a possible cause of other unexplained booms, which are sometimes described as skyquakes.

There does not appear to be any agreement on what causes the booms of the 'Seneca guns'. They have been occurring in several places around the eastern U.S. and in India for at least a century or two.

MYSTERY BOOMS -
IDAHO - 6/7/10 - Monday boom mystifies. At about 3:10 p.m. Monday, people across Twin Falls thought something heavy landed on their roofs. It was thought at the mall. It was thought downtown. It was even thought at the Twin Falls Police dispatch center. Despite all the startled residents, the boom remains a mystery. Twin Falls city police dispatchers originally called out over the police scanner that there might have been an explosion in the area of Fourth and Fifth streets North. Their phone lines lit up “like Christmas trees,” one dispatcher said, with reports of the noise. But no one who called had seen its cause. Officials at Joslin Field, Magic Valley Regional Airport didn’t hear the boom or know of anything that would have caused it. Aircraft flying from Mountain Home Air Force Base can cause loud sonic booms. Monday evening F-15 fighter jets were conducting training exercises in nearby airspace at the time “while adhering to established airspace and altitude restrictions.”
TEXAS - June 2010 - West Dallas residents seek answers about mysterious booms at night. What is it? From where does it come? "It's scary because we don't know what it is. Sometimes it's loud, and sometimes it's real loud." "It was kind of like a little earthquake, a trembling.": "It was loud enough, it shook the house." "It" would be the Mystery Booms of West Dallas. "We've been having these big explosions and no one knows where it's coming from. The window-rattling, wake-up surprises have been random, often occurring late at night, but not always. People have reported the sounds with varying degrees of imprecision and little sense of direction. "I'm thinking it's some kind of explosion, and then you get up and don't see anything. We need to know what's going on." "People have a right to know when they hear a boom it's not bad. And this is approaching the level of a nuisance." From descriptions, "it sounds like a pressure blast of some kind, a manufacturing process of some sort. ... From what I'm hearing, it's not a railroad sound, not a large metallic clang." One resident is targeting an industrial area after speaking with neighboring workers.
Comments from the article - "What kind of power we're talking about that rattles windows for up to 2 miles in all directions... you think it sounds scary inside your house, step outside and listen."
"There is talk of a catastrophe occurring in 2012. I think the explosions you are hearing are the result of underground construction. The elite in Dallas are creating underground bunkers to protect them from imminent disasters."
