Fire in the Sky
Scientists can't say if it was an earthquake and the RAF said the RAF says none of their planes caused a sonic boom.
Seismologists are currently looking into the 3.15pm incident in Berwickshire and Northumberland.
A British Geological Survey spokeswoman said: "We know something happened as we've had lots of reports of the earth shaking and it registered on our equipment."
The data is being studied but the spokeswoman said they could not confirm if it was an earthquake or a sonic boom. But she said the data did not have the 'tell-tale' signs of an earthquake.
A Northumbria Police spokesman said that reports had come in from as far afield as south as Craster and that Lothian and Borders Police had received reports from Burnmouth.
He said that the RAF had reported that although planes were operating in the area it was not believed to be a sonic boom.
It has also been felt in Wooler and Belford as well as throughout Berwick.
The search began around 10 p.m. Wednesday, after someone reported seeing a fireball disappear in the marsh.
The Florida Times-Union reports the search was called off shortly after midnight early Thursday, and state patrol officials say it is believed the fireball might have been a meteor.
The alarm sounded when inhabitants of a mountainous region of Sinaloa state near the border with Chihuahua were startled by the approach of a luminous object in the night sky.
NASA and Mexican emergency services agencies confirmed that the object was a meteorite, whose dimensions and exact place of impact are unknown.
Some witnesses believed it could have crashed to earth between the Gustavo Diaz Ordaz Dam and the town of San Jose de Gracia.
After hours of searching by air and land, an official of the Sinaloa municipality of Sinaloa, Marcial Alvarez, told Efe that the meteorite is believed to have impacted next door in Chihuahua state.
This Saturday observers will fly over the area in search of the meteorite.
It would not be the first time Sinaloa has seen a phenomenon like this. In 1871 a meteorite fell on the settlement of Bacubirito, which with a weight of 22 tons is considered one of the biggest in the world.
"The Quadrantids of 2012 were fantastic," says Broms. "The display was dominated by fairly bright and fast meteors."
NASA's All-Sky Fireball Network recorded 20 fireballs during the outburst. Data from multiple cameras allowed the orbits of the meteoroiuds to be calculated, and they are shown here in a diagram of the inner solar system:
Brian Emfinger of Ozark, Arkansas, photographed this one on Jan. 2nd:
"Wow! What a really nice fireball," says Emfinger. "It emerged very very close to the Quadrantid radiant, but I'm not 100% sure it is indeed an early Quadrantid."
Even among professional researchers there is a lot of uncertainty about the Quadrantids. Because the shower occurs during the deep cold of northern winter, and because its peak is brief (often no longer than a couple of hours), this strong shower is seldom observed. Bill Cooke of NASA's Meteoroid Environment Office hopes 2012 will be different. "We encourage sky watchers to be alert for Quadrantids and send their observations to NASA using the Meteor Counter app," he says. "With a little help, we just might learn something new about this intriguing shower."
