Iceland and 4 Spheres

In Iceland, they have a lot of volcano's so most of the disasters are from volcanic eruptions. 

Volcanoes => Lithosphere/ Atmosphere/ Hydrosphere/ Biosphere 

Volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere.  These particles serve as nuclei for the formation of water droplets (hydrosphere).  Rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere). Particulate matter in the air (atmosphere) falls out, initially smothering plants (biosphere), but ultimately enriching the soil (geosphere) and thereby stimulating plant growth (biosphere).
