Volcanism refers to magma and related gases movement from the interior into the earth surface and the crust. Volcanism can be beneficial and hazardous to human being. Volcanic eruption results to the emission of greenhouse gases that include CO2 from fossil fuels burning. This makes a contribution to the atmospheric pollution and increase in global warming scale. Volcano ash can also be destructive to the infrastructure, especially when it cover roads, railways satellites, and airports runways. It can result to destruction of towns, communities, and people’s properties, while in very abrupt and severe cases, it can result to lose of life and severe injuries.

Volcanic has also resulted to the creation of beautiful landscape that includes land, island, and mountain among other unique features. These features play a great role in attracting tourists in the county. It also offers habitation to pioneer species, after destroying the existing or the old crops and habitants. The high heat level and activities in the earth near a volcano can offer chances for geothermal energy generation in the country (Marshak, 2016).
