Did you hear a loud bang this lunchtime? If you did, don't worry, it wasn't another earthquake, but probably a sonic boom.
The British Geological Survey (BGS) said many people in Norfolk reported a 'felt' event from 12.10pm to 12.40pm in the area around Norwich.
A spokesman said: “People have described 'the whole house shook' and 'it rocked our office building' and 'a loud bang'.
“Data from the BGS seismic network in the region were examined and a signal consistent with a possible sonic origin was recorded at 12:13pm on a station in the area.
“The reports received are also consistent with historical observations received for previous events in the area for events with a sonic origin.”
A spokesman said the sonic boom could have been caused by an aeroplane travelling through the sound barrier over the North Sea. The BGS contacted the RAF but it could not confirm if aircraft were operational at the time.

Apparently the MOD have said that it was caused by an F15 out of RAF Mildenhall.
