Assessing Impacts of Volcanic Ashfall
Volcanic ash may not be the most spectacular or lethal product of an explosive volcanic eruption, but it is the most widespread, and the most likely to affect towns, cities and farmland in the North Island. Freshlyerupted ash contains a range of potentially toxic soluble elements, which are released either rapidly or more slowly upon contact with water or body fluids. Following an eruption, it is normal for the public, civil authorities and agricultural producers to have concerns about the effects of ashfalls on human and animal health, drinking water supplies, crops and soils. In addition, ashfalls can interfere with the functioning of critical lifelines such as electricity and drinking water supplies.
