Around 1,100 small earthquakes have rattled one of Portugal`s mid-Atlantic volcanic islands in less than 48 hours, prompting authorities to activate an emergency plan as experts assess what they have described as a "seismic crisis". Rui Marques, head of the Azores archipelago`s seismo-volcanic surveillance centre CIVISA, said on Monday the earthquakes had been recorded on the island of Sao Jorge since Saturday afternoon.
