An earthquake has been reported in Devon that reached a magnitude 2.7.
The epicentre of the quake, which struck at 1445 BST, was near Bovey Tracey, the British Geological Society (BGS) said.
Police said there had been no reports of injuries but some people said their properties shook.
The BGS said it was an "unusual occurrence", with approximately 10-12 quakes of this magnitude felt in the UK per year.
Radio Devon Listeners said they felt the tremors in Okehampton, Bridford and at Moretonhampstead.
Pat Fleming, from Poundsgate near Ashburton, felt the quake and said: "Huge shakes went right through our granite house.
"We thought that something had exploded."
The last earthquake of a similar magnitude in Devon centred on Dartmoor in 1995, the society said.
