Since the 5.1 magnitude earthquake in the early hours of February 22, the National Geographic Institute has recorded more than 60 aftershocks in Malaga.
So far, the highest intensity of the recurring tremors registered 4.6.
The epicentre of the initial quake, which lasted for a few seconds, was closer to the Moroccan side of the Alboran Sea but reports suggest it was felt in Malaga Province and also in Almeria and Granada.
On January 25 a 6.3 magnitude earthquake with its epicentre in the Alboran Sea caused at least 26 minor injuries in Melilla and was felt across Andalucia and along the Moroccan coastline.
The most recent 5.1 quake has caused no damage or injury.
Experts believe that both earthquakes would have caused considerably more damage if they had happened below land, and not below the sea floor.
