“ashfall maybe just a dust, but it can cause hazard not only in human being and also to other organism .”

     A volcanic eruption can be non-explosive. Non-explosive eruption is a quiet effusion of lava. An explosive eruption can be compared to an atomic bomb explosion, exploding thick and dark ash clouds reaching up to thousands of meters high. Volcanic ash clouds are fine fragments ejected by a volcano during such an eruption. Sometimes they can be seen growing like a giant mushroom enveloping the horizon over an erupting crater causing the surrounding area to be shrouded with darkness. however, after a few minutes, the ash falls back to the ground like rain. This what we call ash fall. after the ash fall, you'll notice that the coarser fragments can be found near the volcano well as you go further the ash becomes finer.

   Heavy ash fall can cause harm to humans, animals, plants, equipment, engines and structures. find volcanic ash is often a rispirable which can cause pulmonary-respiratory disease if inhaled over prolonged period. volcanic ash contains soluble salt which can harm plants. Thick ash that accumulate on the roofs especially when rained on could cause the collapses of houses and buildings. also, acid-bearing ash could cause metal corrosion and destroy household appliances like air conditioner, freezer, refrigerator, radio, television set, computer, etc. ash could likewise affect vehicle engines and cause vehicular accidents. we can not stop an ash falls but we can minimize its adverse effect.
