What is the name of the major volcano that erupted in 2010

Iceland's Eyjafjallajökull Volcano

Explanation:

Iceland's Eyjafjallajökull Volcano eruption happened on March 20, 2010. It consisted of different stages:

The first eruption happened in an ice-free area (1660 m high), this eruption was little but it produced lava. The next phase of the eruption, on 14 April, produced a 2.5 km wide caldera under the ice cap. This led to the melting of such ice, flooding the southern region, 800 people were evacuated. During this phase, the interaction between magma with water created a plume of volcanic ash and gas of over 10 km. This lasted from April 15th to April 21st.

Even though the eruption itself wasn't that big, the melting ice that flooded the surrounded area and the ashes column that blocked the air paths for almost a week, converted this event into one of the most disastrous eruptions.
