Earth tremor felt across England
People from across large parts of England have reported an earth tremor.
The BBC has received calls from people in Yorkshire, the West Midlands, Manchester, Berkshire, London and Gloucestershire about a "quake".
The tremor could be felt in central Birmingham at about 0100 GMT but it is unclear if it has caused any damage.
The US Geographical Survey's website reported a quake of the magnitude of 4.7 and said the epicentre was 30 miles (50km) south of Kingston-upon-Hull.
The West Midlands was hit by an earthquake in 2002 in the Dudley area that reached a magnitude of 5.0 and caused damage to homes.
Jemma Harrison, 22, in Bury, Greater Manchester, said: "It was really bad. I was fast asleep and woke up and the room was shaking and there was a loud bang and alarms were going off."
Natasha Cavey, in Tipton in the West Midlands, said: "All my cupboard doors flew open and the whole house shook, it was unreal. I can't believe it."
David Somerset, 41, from Driffield near Beverley in East Yorkshire, said: "I have never felt one as strong as that one before. I was in my sitting room and the grandfather clock was rattling rather violently.
"It was very strong, I felt the whole room moving."
