On the 9th April, there was a 1.7 magnitude earthquake of the coast of Torrevieja. Yesterday, there was a further quake of 1.4 magnitude less than a mile off the coast which could be felt in both Torrevieja and Guardamar del Segura.
There are no reports of damage.
I remember reading that, a series of small quakes like these are a good sign. The theory says that regular small movements of the plates are preferable to one off large movements. The truth is that nobody can predict what will happen in the future.
