A 2.1 magnitude earthquake hits Scotland as locals hear an 'explosion' after two more aftershocks this week

Scotland has been rocked by another earthquake as locals heard the ‘Big Bang’ sound after two more aftershocks this week.

The British Geological Survey said a 2.1 magnitude earthquake struck Roybridge in the Highlands shortly before 9:30 tonight.

The agency said the rumble occurred at a depth of 7.5 km.

Residents said they felt the quake in Spain, Boheny and Rafburn, with reports of the ‘Big Bang’.

One of them wrote: “Another earthquake in Roybridge???”

Another said: “I just heard a loud noise in Spain, I thought it was someone’s garbage or something.”

A third wrote: “Heard and felt it. ,

The British Geological Survey said: “A small number of reports have been received by members of the public in the Roybridge area indicating that they had felt the event.”

This comes after Scots reported a 3.1 magnitude earthquake in the west of the country on Tuesday.

About an hour later, a magnitude 1.6 earthquake was recorded in Roybridge.

Rosemary Negel, who lives on a farm in Kilmartin Glen near Lochgilfed, said the shaking was so strong that she initially thought something had exploded in one of her sheds.

She told BBC Radio’s Good Morning Scotland: “It kept getting louder and the house vibrated. It kept rumbling until about 10 seconds later so it was very scary.

“I’ve experienced it here before, but never to such an extent. The house never shook like this in the past.

About 200 to 300 earthquakes occur in the UK every year, but the vast majority are so small that no one notices them.

However, between 20 and 30, there is a magnitude greater than 2.0 that can be felt over a larger area.

The largest known Scottish earthquake occurred in 1880 near Loch Away, with a magnitude of 5.2.

Earthquakes in Scotland are often attributed to glacial rebound. Until about 10,500 years ago, much of northern Britain was covered by a thick layer of ice – which pushed rocks into the underlying mantle.

These rocks gradually rise as the ice melts, causing occasional earthquakes.

The UK is also subject to tectonic stresses caused by the expansion of the Atlantic Ocean, which is gradually pushing the whole of Eurasia eastwards, and by a northward movement of Africa, which is pushing south towards Europe.

The most devastating earthquake in Britain occurred in the Colchester area in 1884. Some 1,200 buildings required repairs, chimneys collapsed and walls cracked.

Surrey residents reported a magnitude 3.3 earthquake that violently shook entire buildings.
