Meanwhile, care home residents and those hospitalised in the municipality of Velas, where the majority of the seismic activity has been recorded, have already been transferred to the other side of the island.
Filipe Azevedo, a local hotelier, said people were “very scared”.
He added: “We are all very anxious. It is a phenomenon for which we are not prepared.”
The Mayor of Velas, Luis Silveira, has said that there was no need to evacuate all the residents, but admitted that many had left the island of their own accord.
