An Iceland volcano starts erupting again, shooting lava into the sky

Iceland volcano erupts for fifth time, threatening town and popular spa, showcasing nature's power.

A volcano in southwestern Iceland erupted on Wednesday for the fifth time since December, spewing red lava that once again threatened the coastal town of Grindavik and led to the evacuation of the popular Blue Lagoon geothermal spa.

The eruption began in the early afternoon following a series of earthquakes north of the town of 3,800 people that was largely evacuated in December when the volcano came to life after centuries of dormancy and put on an impressive show of nature’s power.

Although activity began to calm down by early evening, initial estimates found the eruption was the most vigorous in the area so far, as lava shot 50 meters (165 feet) into the sky from a fissure that grew to 3.5 kilometers (2.1 miles) in length, the Icelandic Meteorological Office said.

Barriers built to protect Grindavik deflected the flowing lava that cut off two of the three roads leading to town and was close to reaching the third.

“It’s a much larger volume that’s on the move right now headed for town,” Grindavik Mayor Fannar Jónasson told national broadcaster RUV. "The lava has already conquered (a lot).”

Workers and anyone still in town were ordered to leave earlier in the day, police said.

At one point, a dark plume of ash boiled up over the crater from an explosive interaction of magma hitting groundwater, scientists said.
