Relatively rare events like volcanic eruptions are difficult to anticipate and plan for. In their immediate vicinity they have the potential of being apocalyptic events; i.e.Vesuvius/Pompei (livescience) or the Yellowstone ‘super volcano’ hypothesis (ScienceAlert). Not everyone wants to consider such end-of-the-world scenarios. Volcanos affect us all, however, even if they happen at the other end of the world and lead to long-term climatic changes. An example here is Mount Tambora volcano or Krakatau which resulted in global impacts that included failed harvests in Europe and laundry freezing on the lines in summer in the US city of Boston (Blast from the Past, Smithsonian)
Volcanic Eruption - Volcanic Ash
Volcanic ash is deadly! A multitude of dangerous particels and gases, such as aerosols, are carried in volcanic ash. Some of these include Carbon dioxide, Sulfates (sulfur dioxide), Hydrochloric acid, Hydroflouric acid. Each have different but serious effects on human health if exposed (see CuttingEdge) . Volcanic ash is also a hazard for air travel, grounding and stranding passengers (i.e. the Eyjafjallajoekull, Iceland, April 2010; Wikipedia; BBC impact on Scotland’s natural resources (info); How it unfolded. The University of Icleland has an info sheet on Volcanic Gas Hazard.
