People living in the area of the Highlands affected by the earthquake shared their experiences of the event.
Eddie Lopez, 33, of Claggan, Fort William, said: “The light in the bathroom was swinging and it felt like the house was actually moving. It was just bizarre.”
Joan Morrison, 31, of Lochaber Road, Fort William, said: “I could feel the floor vibrating under my feet and thought something had happened to my house.”
Dianne Bowman and her husband, David, live in Duisky – about a mile from the epicentre of the quake.
She said: “We heard a big bang and a rumbling sound.
“We thought it was thunder and lightening and my husband commented that it must have been very close to our house.
“We were quite shocked to discover it was an earthquake.”
Councillor Bill Clark, Caol and Mallaig, who stays at Tomonie, Banavie, said it was the strongest earthquake he had experienced.
He said: “The whole house really shook and I looked out of my window to see my neighbours out it the street trying to find what happened.
“We’ve had the odd wee tremor in the past, but I have never felt anything like this before.”
And Councillor Andrew Baxter, Fort William and Ardnamurchan, said he was at a community council meeting in Nether Lochaber Village Hall at the time of quake.
He said: “We heard a loud rumble that lasted for about 10 seconds. It sounded like a lorry crashing into something.”
Most earthquakes in the Highlands are less severe, such as the magnitude 1.3 quake felt in Acharacle, Lochaber, just after 7pm on Tuesday.
However, there was a magnitude 5.0 quake in Inverness in 1901 and a 4.1 event in Oban in 1986.
The biggest recorded earthquake in the UK was a magnitude 6.1 quake just off the coast of East Anglia in 1931.
