Parts of the UK were rocked by a 5.1 earthquake this morning.
People reported their homes ‘jamming’ for minutes as the tremors were felt in parts of northern Scotland.
It was reported to have happened at 5.23am off the northeast coast of Shetland.
It was felt in Shetland, Aberdeen, Ellon, Stonehaven, Helmsdale, Inverurie, Lairg, Huntly, Banff and Fraserburgh, according to the British Geological Survey.
He said reports described: “lying in bed and hearing a low rumble”, “three waves of vibrations in about three seconds”, “it woke me up as the windows were shaking”, “the bed was shaking and the windows were creaking”, “the mirror was shaking” and “I felt it as much as heard it, enough to wake me up”.
More than 70 members of the public reported the quake, which lasted about two minutes, according to the United States Geological Survey.
There are around 200-300 earthquakes in Britain each year, but the vast majority are so small that no one notices them.
However, between 20 and 30 has a magnitude greater than 2.0 which can be felt over a wider area.
Ryan Thomson, who lives in Shetland, said he woke up to something that looked like a “low-flying aircraft”.
He said: “I first woke up to the sound which was very much like a very low flying jet or extremely loud thunder, it wasn’t until I saw the lampshade moving that I clicked that it could be a small earthquake.
“There wasn’t much movement here, I believe other parts of Shetland felt it more, but the noise was extremely loud and quite alarming.
“Earthquakes are of course very rare but not unheard of here in Shetland.
“There was one about five years ago in a similar location, but it was certainly the loudest and most conspicuous I have ever experienced in Shetland.”
The most devastating earthquake in the country occurred in the Colchester area in 1884. Some 1,200 buildings needed repairs, chimneys collapsed and walls cracked.
Earthquakes in Scotland are most often attributed to glacial rebounds.
Until around 10,500 years ago, much of the north of the UK was covered in a thick layer of ice – which pushed rocks into the underlying mantle.
These rocks have been slowly rising since the melting ice, causing occasional earthquakes in the process.
