Hazards of Volcanoes

Volcanoes are geological features of the Earth that benefit us in many ways, but a the same time they also act as hazards.


Ash Falls- Ash fills the air releasing particules, destroys forest, water vegetation, effects people the most, creates eerie darkness, irritates people, crashes airplanes, destroys roofs


Hot Ash Flows- Most destructive, burns everything in path, dangerous, moves fast, pores into water bodies, fires, complete destruction


Mudflows- Floods of water, sand, mud, travels 50km per hour, rip huge bolders from ground, destroys everything in path, houses rip apart


Volcanic Tsunamis- Tsunami comes when volcanic particles flow in the ocean


Lava Flows- Lava pores across floor from vents, molten rock lava, 1km/ hour or day, moves very slowly, destroys buildings leaves land useless


Volcanic Gas- releases gas when water boiled by volcanic heat, rises 100meters high, releases sulphur gases, smells like rotten eggs, stings the throat and nose, damages crops, fluorine & Carbon Dioxide contaminate grasses eaten by animals killing humans & animals, destruct a lot of things, and kill everything in its path 


These are all Volcanic hazards, but Hawaii makes sure no body gets affected by these hazards.
