The British Geological Survey (BGS) recorded the tremor in the Moidart area of the Scottish Highlands shortly before 3.45pm, saying it was the biggest quake to hit the region since a 4.1-magnitude earthquake near Oban in September 1986.
It added that it "was felt widely across the west of Scotland".
Residents in the region took to Twitter to share their experiences of the earthquake.
One wrote: "Just experienced 2 earthquake tremors here in Scotland. Never felt anything like that, like the ground beneath us was exploding. Terrifying!"
Another said: "Earthquake! Did anyone else from Scotland feel that??!"
