© British Geological SocietyAn earthquake has been felt in Lincolnshire and Yorkshire.
The BGS said the 3.9 magnitude quake was felt in the north east and north of Lincolnshire, Kingston-upon-Hull and East Riding of Yorkshire at 11.14pm on Saturday.
It was centred near Grimsby and had a depth of 11 miles.
One Twitter user in Hull said: "Our house moved and the furniture shifted", while another wrote: "(It would) only have lasted seconds but scary nonetheless".
There are also reports of the tremor having being felt as far away as Nuneaton, where one resident described it as "really small, like little shake for about three seconds".
Grimsby residents told the Grimsby Telegraph that the shaking lasted between three and five seconds.
The quake is the largest in the area since Market Rasen's 5.2 event in 2008.
The largest earthquake this year took place in Cwmllynfell in south Wales on 17 February with a magnitude of 4.6.
The BGS said that earthquakes of this size happen approximately every two years in the UK, although for anyone still shaking after Saturday night's quake, there are around 8,000 every year around the world that are larger.
Comment: Following a 4.6 magnitude earthquake in the UK in February this year, the strongest to have hit the UK in 10 years, a British Geological Survey tweet stated that, "Events of this magnitude only happen in the UK every 2-3 years."
Actually, there have been about 7 similar-strength quakes in the UK in the last 3 years alone...
22 May 2015 - A 4.2 magnitude earthquake 'causes homes to shake' in Kent, UK
25 May 2015 - Magnitude 3.0 earthquake recorded in North Wales
29 Jan 2015 - Britain's second earthquake in 48 hours strikes in East Midlands
7 Mar 2016 - Earthquake 'shook houses' in south-east England
3 Jan 2017 - 3.9 magnitude tremor strikes off UK coast - biggest quake for nearly a decade
4 July 2017 - Earthquake recorded off Shetland was largest in UK for nine years
5 Aug 2017 - Scottish Highlands are rocked by their biggest earthquake for 30 years
We are seeing a marked increase in seismic activity around the world lately, could it be related to scientists' predictions that major earthquakes for 2018 due to slowdown in Earth's rotation?
