The newest eruption, in May 2011, is at Grímsvötn under the Vatnajökull glacier. Grímsvötn volcano has sent thousands of tonnes of ash into the sky in few days, raising concerns of a repeat of the travel chaos seen across northern Europe .
So far it's merely causing travel delays. Some 500 flights have been canceled across Europe. Nothing quite major other than inconveniences for now. Hopefully, that's all there is to it! Just lots of smoke!
