Icelanders take advantage of Iceland's volcanic nature mostly in geothermal ways . ... Near volcanos, there are thinner areas of the Earth's crust than in other areas. In these thinner areas, we can dig far enough to get an area of warmth – much warmer than on the surface.
Are volcanoes more positive or negative?
Positive : Lava and Ash deposited during an eruption breaks down to provide valuable nutrients for the soil... this creates very fertile soil which is good for agriculture. Negative: Deadly and devastating Lahars are made when... ash and mud from an eruption mixes with rain or melting snow making fast moving mud flows.
Are volcanoes more positive or negative for Iceland Why?
It was evident from the research that volcanic activities have tre- mendous effects on the Icelandic people; some positive while others negative . They affect the daily human activities of agriculture, flight and even road transportation. The eruptions can lead to huge losses in terms of property.
Why Iceland experiences a lot of volcanic activity?
The reason that there are so many volcanoes in Iceland is that the country lies where two tectonic plates meet . Basically, the tectonic plates are large pieces of the Earth's crust in the layer called the lithosphere. Since these plates are not fused, extremely hot substances are able to rise from within.

Is Iceland a supervolcano?
listen)) is a large volcano in southern Iceland . It is very active; twenty eruptions have been documented between 930 and 1918, at intervals of 20–90 years. ... In comparison, the Eyjafjallajökull 2010 eruption had a VEI of 4.
