Dear Colleagues,
We would like to invite you to contribute to the following session on the potential environmental and health impacts of volcanic emissions and gas blowouts at the Cities on Volcanoes 10 conference which will be held from 2 – 7 September 2018 in Naples, Italy (https://www.citiesonvolcanoes
Abstract submission deadline is 10 May 2018.

S1.7 | Impacts of volcanic emissions and gas blowouts on the surrounding environments: understanding the processes to constrain the hazards
Explosive eruptions, effusive activity and quiescent degassing represent important sources of volcanogenic elements. Once emitted onto the Earth’s surface as well as into the atmosphere, these elements are easily transported and can affect the surroundings of volcanic systems. Volcanic emission products may readily interact with meteoric water and living beings, introducing volcanogenic elements into the biogeochemical cycles.
Effects of volcanic emissions can be observed in acid rains, plant coverage, chemical weathering, and groundwater as well as in potential incidence of health diseases. Understanding of the processes that govern elements’ mobility (e.g., partitioning between melt and gases, reactions during transport and deposition, accumulation of potentially toxic elements) is fundamental for constraining the hazards due to volcanic emissions.
A specific part of the session deals with hazards related to natural gas emissions and to gas-blowouts in urbanized areas. Natural gas manifestations often represent touristic attractions, but may be hazardous for visitors and casualties episodically occurred. Occasionally, because of messy urban expansions, settlements are too close to natural manifestation, implying a high-risk for casualties and causing prolonged evacuations of the nearby exposed houses. Also in zones without natural gas manifestation, any time that drillings reach gas pressurized shallow aquifers, hazardous gas-blowouts may occur. Indeed, similar accidents occurred with a severe impact on people and animals, leading to prolonged evacuations, with severe economic damages.
This session aims to share experiences on studies of volcanic emissions, gas blowouts and their impact on surrounding environments. We encourage submission of abstracts on a broad range of topics dealing with potential environmental and health impact of volcanic emissions and gas-blowouts.
