(REYKJAVIK, Iceland) -- Iceland issued a red alert to airlines Saturday as the Bardarbunga volcano begins erupting.
The warning is the highest possible alert, bringing the possibility of significant ash emissions.
"It is believed that a small subglacial lava-eruption has begun under the Dyngjujökull glacier," the warning from the Icelandic Met Office reads.
The conditions come as a result of intense earthquake activity at the volcano over the past week.
Ash can wreak havoc on plane engines and ground transatlantic flights, similar to a major 2010 eruption that caused massive travel disruptions for days and delayed millions of passengers.
