Please specify which Icelandic volcano you're referring to. Iceland has many active volcanoes, each with its own eruption history and impact.

For example, some notable Icelandic volcanoes include:

* Eyjafjallajökull: This volcano's 2010 eruption caused significant disruption to air travel across Europe, grounding flights for days due to the ash cloud.

* Grímsvötn: This volcano's eruptions often cause flooding due to the melting of the surrounding glacier.

* Katla: This volcano is known for its potential for large-scale eruptions with significant impacts on the surrounding area.

Once you specify the volcano, I can provide more detailed information about the damage it caused.
