Iceland raises aviation volcano alert to red as small subglacial eruption is under way

Iceland's Meteorological Office says a subglacial eruption is underway at the Bardarbunga volcano, which has been rattled by thousands of earthquakes over the past week.
Vulcanologist Melissa Pfeffer said seismic data indicates that lava from the volcano is melting ice beneath the Vatnajokull glacier. She said it was not clear when, or if, the eruption would melt the ice and send steam and ash into the air.
Minutes earlier, Iceland raised its aviation alert for the volcano to the highest level of red on Saturday, indicating an eruption that could cause "significant emission of ash into the atmosphere." Red is the highest alert warning on a five-point scale.
The alert means that all air traffic in the area is banned.
