UME Emergency Military Unit was deployed to El Hierro on Wednesday as the island remained on yellow alert amid fears of a volcanic eruption. The Defence Minister, Carme Chacón, was also due to travel there on Wednesday afternoon to supervise their work, and spoke of the UME’s deployment as a preventive measure to assist emergency services in any evacuation over the increased seismic activity on the island. EFE indicates that there is a 15 percent probability of an imminent eruption, but the island’s government has ruled out any need to evacuate the island. The President of El Hierro’s Cabildo, Alpido Armas, said, ‘That’s not going to happen. We will not need to evacuate 4,000 people. If there is an eruption, it will not be a violent one and the worst that can happen is that a 200 metre mountain emerges’. Fifty three people were evacuated from Frontera due to the seismic activity and it’s understood that they will not be allowed home for the moment. Local schools there were also closed as a precaution because of the risk of landslides. The last volcanic eruption on El Hierro was in 1793, when the Lomo Negro volcano erupted. The last on the Canary Islands was just 40 years ago on La Palma.
