Soils that developed from the volcanic ashes often thought to contribute greatly to improve soil fertility, without regard to the nature and composition of the volcanic ash produced. Volcanic ash generated from the results in volcanic activity has a different composition, there are basaltic, andesitic and granitic, thereby affecting the process of formation and characteristics of the soil.

Volcanic Ash : Chemical Composition, Environmental …

Ash produced as a consequence of explosive volcanic eruptions can cause multiple hazards both close to the volcano and at great distances. Explosive volcano eruptions often release volcanic plumes into the atmosphere, which consist of tephra (submillimeter-sized rock particles), water vapor and other gases such as carbon dioxide (CO2), sulfur dioxide (SO2) and hydrogen sulfide (H2S).

Volcanic ash poses no health threat in wet weather since the ash particles agglomerate, and it is washed out from the air and cannot be inhaled. In the event of rain, only very low concentrations of volcanic ash are likely to be deposited on the ground and the general public is unlikely to experience significant health effects once the rain dries.
