The Greek island of Santorini has been reportedly been hit by hundreds of tremors this year, while a 5.2-magnitude strong quake hit earlier this month.
It is thought that, due to earthquakes, the four countries listed make up nearly 80 per cent of the modelled average economic loss each year, which amounts to a staggering 7 billion Euros (£5.816bn), according to EFEHR.
At a depth of roughly 10km, its impact could be felt across swathes of the affected Portuguese region as residents flocked to social media site X to describe the tremors and the moment they felt buildings shake.
The earthquake hit when head Portuguese football coach Bruno Lage was about to speak at a conference before Benfica’s Champions League play-off.
The event follows an earthquake measuring 4.7 on the Richter scale that rocked Lisbon and surrounding areas on Monday.
