I live maybe three or four miles (as a crow flies) from this area of the city but I/we haven't heard any of these. No one seems to know what is causing them---remember the mysterious BOOMS coming from the Naval Observatory in DC (Cheney's house) a few years ago? :shrug:
http://www.timesdispatch.com/servlet/Satellite?pagename=RTD/MGArticle/RTD_BasicArticle&c=MGArticle&cid=1031778953029A series of loud booms that shook a North Richmond neighborhood was reported to police and fire officials by residents late Tuesday night and early yesterday.
Johnson said seismic activity has been ruled out as a possible cause of the tremors, along with construction, low-flying planes or military exercises.
Residents believe it may be a problem stemming from the sewer system, mentioning a foul smell coming from storm drains and basements.
So they held a town meeting just last nighthttp://www.timesdispatch.com/servlet/Satellite?pagename=RTD%2FMGArticle%2FRTD_BasicArticle&c=MGArticle&cid=1031779281369&path=!news&s=1045855934842Richmond's northern neighborhoods were jolted again yesterday about 12:45 p.m. as more of the so-far-unexplained booms shook homes and rattled windows, residents said.
"The ground shook, and we heard a muffled boom," said one man who lives in the 4000 block of Hermitage Road.
Yesterday's booms were preceded by another clap that hit Saturday about 11 p.m., and some residents described that one as the loudest they had yet heard.
The booms and shakes started Nov. 1, and they have recurred on at least five days since then, according to city emergency services spokesman Bill Farrar yesterday.
"I'm betting it's an earthquake," said a woman who lives on Maple Shade Lane.
A duty seismologist at the U.S. Geological Survey's National Earthquake Information Center in Golden, Colo., said the center's sensors did not pick up indications of a quake in Richmond yesterday. If the booms were the result of an earthquake, they would have been recorded, the federal seismologist said.
