The Canary Island of El Hierro, the smallest and farthest southeast of the Spanish Atlantic archipelago, is steeling itself for a possible volcanic eruption after a series of tremors was felt during the weekend. The strongest of these, 3.4 on the Richter scale, shook El Hierro on Saturday.
The regional government of the Canaries reacted by raising the seismic alert level to yellow for the first time in the recent history of the islands.
The security department of El Hierro warned that there will be further activity over the next few days but asked residents to remain calm as "these seismic movements are normal."
However, María del Carmen Morales, the island's security chief, warned that evacuation of El Hierro may occur. "The eruption will give us plenty of notice, so we will have sufficient time to evacuate the population and take them to a safe place," Morales said.
"At the moment, what's important is to remain calm," said Martín Marrero, spokesman for the regional government of the Canaries.
