In theyear1980, a powerfullandslideoccurredcreatinga largecrater.Theeruptionof themountainandextrusion of lavaextendedforsix years.Geographicalexpertsforecastthatmoreeruptionsare likelyto occurin thefuture(Carson, 2000).Thoughmanypeopledidnot knowof thepotential of sucha volcanic eruption,Volcanologists andresearchers werecarryingout their researchon themountain.. Some Monthsbeforethe mountainerupted,officials dealing with geography and volcanologists had set up campclose to the mountain researching about it. Someof theeffectsof the volcanic eruptionis thatitkilledpeople,makingriversflooddueto meltedicedamagingpropertyanddestroyinghomes(Parchman, 2005).Describetheeruptionof Eyjafjallajokull in Iceland,in2010.
