Pine processionary Pine processionary The pine processionary ("Thaumetopoea pityocampa") is a moth of the family Thaumetopoeidae. Sometimes placed in the genus "Traumatocampa", it is one of the most destructive species to pines and cedars in Central Asia, North Africa and the countries of southern Europe. The urticating hairs of the caterpillar larvae cause harmful reactions in humans and other mammals. The species is notable for the behaviour of its caterpillars, which overwinter in tent-like nests high in pine trees, and which proceed through the woods in nose-to-tail columns, protected by their severely irritating hairs, as described by the French entomologist Jean-Henri Fabre.
International Volcanic Health Hazard Network International Volcanic Health Hazard Network The International Volcanic Health Hazard Network (IVHHN) is an organization that provides research and information on the health hazards and impacts of volcanic eruptions. IVHHN work covers a range of research areas including volcanology, toxicology, public health and exposure science, with the goal of determining the health impacts of volcanic emissions and how to protect exposed communities. According to the IVHHN website, the main aims of IVHHN are to: Improve Communication Promote Research Instigate Collaboration IVHHN has created a range of evidence-based audio-visual and printable products on the health hazards of volcanic emissions and community
