Volcanoes bring about a diversity of hazards to human culture, including clouds of hot gasses carrying rock and sand, blast effects, ash falls, and mud flows on the positive side, it can be said that, unlike earthquakes, volcanoes generally give plenty of warning that they are awakening, although the actual moment of. Another positive side effect was that the ruapehu eruptions provided local experience in the management of small volcanic eruptions (keys, 1996 paton et al, 1998) this study was initiated to further investigate the effects of the 1995- 1996 ruapehu ash falls on a number of communities located in the. Category: volcanic effects aso viewed from the visitors center small plume above aso during a period of mild strombolian eruptions, december 30, 1991 photograph by mike lyvers that's a good question i guess the main good effect that volcanoes have on the environment is to provide nutrients to the surrounding soil.

As a rule, the cooling influence of an individual volcano will dominate for the period immediately after the eruption but the warming impact will last much longer so the significance of each depends on the timeframe being considered a very large volcano in 2011 may significantly reduce temperatures in. Explosive volcanic eruptions affect the global climate mainly through injecting sulfur bearing gases into the stratosphere, which oxidize to form sulfate aerosols stratospheric sulfur aerosols spread around the globe by the atmospheric circulation, producing surface cooling by scattering solar radiation back to space. Magnitude is no doubt a key factor and, most fundamentally, human impact can be hypothesised to correlate positively with eruption magnitude (torrence and grattan, 2002a), measured either via semi-qualitative means such as the widely used volcanic explosivity index (vei newhall and self, 1982) or. Positive effects volcanic eruptions are a vital part of the earth's ecosystem the gases produced by volcanic eruptions created the atmosphere in the early stages of the earth's formation, which allows it to retain water and sustain life over time, the eruptions from shield volcanoes accumulate into habitable.

In this answer i will discuss the positive impacts of volcanic activity these positive impacts are geothermal energy, tourism and fertile soils the first positive impact i will discuss is geothermal energy geothermal energy is heat that is generated by the plumes of magma that rise from the earth's core to the. Volcanoes are one of the most spectacular and beautiful features of the physical world on the other hand, great volcanic eruptions in historic times have brought death and destruction to many areas around the world erupting volcanoes have claimed more than 80 000 lives in the twentieth century and over 260 000 since. There are many reasons that large volcanic eruptions have such far-reaching effects on global climate first, volcanic eruptions produce major quantities of carbon dioxide (co2), a gas known to contribute to the greenhouse effect such greenhouse gases trap heat radiated off of the surface of the earth.

  • Volcanoes have the capacity to produce widespread destruction by covering cities and towns with ash and lava however, volcanic eruptions also create islands, and the minerals in volcanic ash.

Volcanic eruptions can have a devastating effect on people and the environment however, unlike earthquakes, volcanoes can also have a positive impact on an area these positive impacts can help to explain why people choose to live near volcanoes. The ensuing disaster on montserrat has become an example of the extensive impact of a long-term volcanic eruption in an exposed, proximal society this is not to say that there aren't also significant benefits afforded to those living in small island developing states (sids), and global pressures also bring many positives. Volcanic ash can be a potent time-release capsule of nutrients in soil agriculture in areas covered with volcanic ash tend to be more fertile for that reason and that's why humans often choose to live in the otherwise dangerous area around a volc.
