A warning has been issued for Spanish holidaymakers as the Costa Del Sol was named as a Spanish region at the highest risk of earthquakes.
It comes as northern Spain was today hit by a 4.1 magnitude earthquake.
The National Geographic Institue (IGN) recorded the quake in the early hours.
Police received a number of reports of tremors overnight but no one has been hurt in the quake. Today's quake follows one on Saturday.
A 3.2 magnitude quake was felt in Malaga.
The Junta regional government today announced that Andalucia is one of the regions in Spain at the highest risk of a major earthquake, although on a global scale this risk is moderate.
The government has now called for an emergency response drill along the province of Cadiz in preparation of a potential quake.
The aim of the drill will be to test the response in the event of a major emergency and the capacity for quick movement and the maintenance of safety of people and the environment in the area.
There will be a large-scale emergency response drill coordinated by Emergencias Andalucía, the Centro de Emergencias Sanitarias 061, National Police, Guardia Civil, fire brigades and town halls.
Local police, the Red Cross, Maritime Rescue and Spain's Military Emergency Unit will also be in attendance as well as local Civil Protection volunteer groups and the National Emergency Radio Network REMER will also participate.
