Studies of the respiratory health effects of different types of volcanic ash have been
undertaken only in the last 40 years, and mostly since the eruption of Mt. St. Helens in 1980 …

Volcanic air pollution from both explosive and effusive activity can affect large populations
as far as thousands of kilometers away from the source, for days to decades or even …

The Earth's history is punctuated by large explosive eruptions that eject large quantities of
magma and silicate rock fragments into the atmosphere. These tephra particles can …

Abstract The Triassic Chang 7 Formation is a rich lacustrine source rock in the Ordos Basin,
central China. Petrographic and geochemical analyses were performed in order to research …

During volcanic eruptions and their aftermath, communities may be concerned about the
impacts of inhaling volcanic ash. Access to effective respiratory protection (RP) is therefore …

The formation, composition and physical properties of lunar dust are incompletely
characterised with regard to human health. While the physical and chemical determinants of …

Preservation of organic carbon (C org) in marine sediments plays a major role in defining
ocean-atmosphere CO 2 levels, Earth climate, and the generation of hydrocarbons …

We performed a quantitative hazard assessment to determine the potential impacts of
volcanic tephra fall on human health and infrastructure in the vicinity of Mt. Etna (Italy). Using …

Pyroclastic density currents (PDCs) are hazardous and destructive phenomena that pose a
significant threat to communities living in the proximity of active volcanoes. PDCs are ground …

Analyses of air, water and vegetation samples collected in June 2008 offer new insights into
the environmental effects of the May 2008 Chaitén eruption on Argentina, which was subject …
