Two small earthquakes were felt in Glen Coe on Wednesday evening.
People who live in and around Ballachulish, near Glencoe village, have also told of hearing a deep rumbling sound.
British Geological Survey, which records seismic activity, detected a magnitude 1.9 earthquake at 17:40 and a magnitude 1.7 quake six minutes later.
A number of small earthquakes are regularly recorded in the Highlands and Inner Hebrides.
They have previously been recorded in Fort William and Jura.
In the Highlands, earthquakes are linked to seismic activity along the ancient Great Glen Fault, a zone of fractures in two blocks of rock that are moving slowly in opposite directions.
The Great Glen's best-known features include Loch Ness.
The earthquakes rarely cause any damage, but the Kessock Bridge at Inverness was designed to withstand quakes.
A waste water pipe taking sewage from North Kessock on the Black Isle under the sea to South Kessock in Inverness was also constructed to be "quake-proof".
In the past, earthquakes have been felt in Inverness.
The city's Town Steeple on the corner of Church Street and Bridge Street was twisted during an earthquake in 1816.
