Volcano Erupts in Iceland Near Power Plant, in 'Worst-Case Scenario'

A volcano in southwestern Iceland began erupting Monday, posing a risk to the nearby Svartsengi Power Plant and the town of Grindavik. "We are looking at a worst-case scenario," said Thorvaldur Thordarson, a volcanologist in Iceland. "The eruption appears big, and only about two kilometers from major infrastructure." The New York Times reports: Thousands of earthquakes had been detected in Iceland since late October, according to the Icelandic Meteorological Office. In November, with homes and roads being damaged, the authorities declared a state of emergency and evacuated Grindavik, a town of more than 3,000 people near the volcano. More recently, the Meteorological Office warned of a "significant likelihood of a volcanic eruption in coming days." Volcanic eruptions are not uncommon in Iceland, which has fewer than 400,000 residents and about 130 volcanoes. Since the 19th century, not a decade has gone by without one, Iceland's tourist website tells interested visitors. The occurrence of eruptions remains "entirely random." The country straddles two tectonic plates, which are themselves divided by an undersea mountain chain that oozes molten hot rock, or magma. The current seismic activity has not affected one of Iceland's best-known volcanoes, Katla, which some scientists worry is due for an eruption. Katla has erupted five times since 1721, at intervals ranging from 34 to 78 years. The last major one was in 1918. Last month, Icelandic authorities started building defense walls around the geothermal power plant to protect it from lava flows. "Authorities said they were preparing to construct a large dyke designed to divert lava flows around the Svartsengi geothermal power plant, located just over 6 kilometers (4 miles) from Grindavik," reported Reuters in mid November. "A spokesperson for HS Orka, operator of the power plant, said it supplies power to the entire country, although a disruption would not affect power supply to Reykjavik."
