Cornwall residents said they felt the earth move this afternoon – but what caused the earthquake that shook the ground?

The quake was confirmed to be a rare event – recording a magnitude of 4.4.

And now the experts have revealed what caused it.

The center was located in South Wales, about 20 kilometers from Swansea.

The earthquake was felt across much of the country, including Cornwall.



Areas where the earthquake was felt

Richard Luckett, a seismologist at the British Geological Survey, said it was the biggest earthquake in the UK since 2008.

He told the Herald: “There was a magnitude 4.4 earthquake in South Wales, about 12 miles NNE of Swansea.

“This earthquake was felt across much of Wales and England, with the most distant reports to date from Birmingham and Devon.

“This is the largest earthquake in the UK since the 5.2 magnitude Market Rasen earthquake in 2008.”

Swansea University was evacuated and people ran through the streets in fear as the quake has been compared to everything from a “massive explosion” to a car accident, reports the Mirror Online.

What is an earthquake?

Movements within the earth’s crust cause stress to build up at points of weakness and deformation of rocks, according to Geological Survey.

Stored energy accumulates in the same way that energy accumulates in the spring of a watch when it is wound.

When the stress eventually exceeds the resistance of the rock, the rock fractures along a fault, often at an existing area of ​​weakness in the rock. The stored energy which is suddenly released like an earthquake.

Intense vibrations, or seismic waves, propagate from the initial point of failure, the focus, like ripples on a pond. These waves are what make the ground tremble and can travel great distances in all directions.

Near the hearth, the waves can be very large, making them extremely destructive.

What is the British Geological Survey?

The British Geological Survey is the world’s leading geological survey. It focuses on science of public interest to government and research to understand terrestrial and environmental processes.

As a public sector organization, BGS is responsible for advising the UK government on all aspects of the geosciences as well as providing unbiased geological advice to industry, academia and the public.

The BGS is part of the Natural Environment Research Council (NERC), which is the UK’s leading agency for funding and managing research, training and knowledge exchange in the field of human sciences. environment. NERC falls under the UK Department for Business, Innovation and Skills (BIS).

It also undertakes a broad program of research, investigation and monitoring abroad, including major institutional strengthening programs in the developing world.
