English county hit by 15 earthquakes in space of 48 hours with houses shaking

Fifteen earthquakes shook Cornwall in the space of 48 hours, the British Geological Survey have confirmed.

Residents describing how a ‘seismic event’ on Tuesday and Wednesday “made their houses shake”.

A tremor with a magnitude of 1.5 hit the Redruth area yesterday, the largest of fifteen earthquakes over the two-day period.

It made windows rattle, locals say, as the scary earthquake passed after a few seconds.

CornwallLive report that the cause of the quakes is actually known.

Geothermal at United Downs, near Redruth, has confirmed the reports are related to geothermal drill testing at the site.

It is assuring people that operations have been temporarily ceased while teams attempt to understand the cause.

Posting online, United Downs Geothermal said: “As part of the UDDGP testing we did cause some micro-seismicity.

“Although this was within our regulatory limits we are stopping operations until we understand the cause,” it said.

“We apologise if this has caused alarm”.

One person said it made her “windows rattle” while others said it felt like an earthquake and made “houses shake”. Others likened the feeling to heavy thunder and lightening.

Earlier this month it was revealed that Cornwall’s lithium potential is of ‘global significance’ after geothermal drill tests were carried out.

Cornish Lithium, based at Tremough Innovation Centre in Penryn believes the Duchy holds some of the best reserves of the rare mineral.

This makes Cornwall a potential world leader in the field and is seen as a potential cash cow for the county and a way to revive its mining industry but with 21st century technologies – and lead to the creation of hundreds of jobs in the county.

Lithium is used in batteries for smartphones and electric cars and demand for the metal has rocketed in recent years.

The company said its preliminary results from samples taken in deep geothermal waters at the United Downs Deep Geothermal Power Project show some of the world’s highest grades of lithium and best overall chemical qualities encountered in published records for geothermal waters anywhere in the world.
