El Hierro’s unprecedented long eruptive phase surprises scientists

January 3, 2012CANARY ISLANDSThe underwater volcano off the small Canary Island of El Hierro became active in July 2011 and has continued to be active on and off ever since, something described as ‘surprising’ by scientists. In a regular press conference on Jan 3, Nemesio Pérez, Director of the Department of Environment of the Institute of Technology and Renewable energy (ITER) said that it was ‘surprising’ that the volcano was continuing in its erupting phase. He told the press that historically, the average eruption of a Canary island volcano has been around thirty days although a document found dating from the seventeenth century speaks of an ancient eruption that lasted six years. The volcano, which has been active in the sea ( Mar de las Calmas) near the southern town of La Restinga has led to severe disruption for the people of the island with regular tremors rumbling almost every day. Three large tremors were noted by the National Geographical Institute (IGN) between Dec 26 and Dec 28 but the latest earthquakes listed by the Institute show daily activity in the Canary Island region. A report in the ABC newspaper said that new activity such as bubbles, steam and fine materials have been seen in recent days following a period of quiet. The island continues to be on yellow alert. Guardia Civil helicopters and research aircraft continue to fly over the ever increasing stain in the sea, keeping watch on developments. Regular updates, videos and pictures can be seen here. The Canary Islands are a popular holiday destination, especially at this time of year, because of its pleasant year round climate and sandy beaches. El Hierro is the smallest of the seven islands that make up the archipelago, lying to the west. It is the closest to the shore of North Africa. The island has a population or around ten thousand people. Scientists are unsure of exactly what will happen with the volcano and are monitoring developments closely. Some unusual activity such as a sudden increase in the population of jellyfish in the area have been seen. Emergency plans have been in place since the volcano started erupting in case an emergency evacuation of the island becomes necessary. –Digital Journal

    Earthquake Report has done an AMAZING job of informing the world of the submarine eruption in the Canary Islands. I have watched with utter fascination. Thanks for your tireless efforts—I don’t really know how you do it, but keep up the good work! I was very glad to see your post here. I hope that you will read here often. Alvin scours the news from around the world and presents it here in a timely manner and readable format.
