Volcano in Iceland has airlines on alert

Iceland On High Alert For Volcano Eruption

In 2010, a volcano in Iceland erupted and devastated the country's traveling industry. Now, geologists say it might be time to take another hit. Roughly 3,000 tiny earthquakes that have occurred recently might be a sign that another volcano is getting ready to blow.

The country bumped its aviation alert level of a possible eruption up to orange - the second-most severe level.

Which likely has the country bracing itself. The heavy volcanic ash from four years ago forced Europe's airspace to close for six days and affected some 10 million people. It also cost airlines billions of dollars as more than 100,000 flights were canceled.
