The Katla volcano located under the Mýrdalsjökull glacier in southern Iceland has experienced a swarm of earthquakes lately. These earthquakes are more concentrated than those that occurred last year and may pre-stage an eruption. The Katla volcano is just east of, and much larger than the Eyjafjallajokull volcano which erupted last year and spewed ash that disrupted air travel throughout Europe. The Katla volcano erupts about every 100 years. The last eruption was in 1918.
From the Volcanism Blog:
A possible small eruption under the Mýrdalsjökull ice cap in south Iceland has produced a surge of glacial meltwater, a jökulhlaup, which has caused flooding and cut the main road through the area. A bridge has been swept away, and local evacuations are apparently taking place.
That was just a volcanic burb.
