1745por Scott, Samuel, Pfeffer, Melissa, Oppenheimer, Clive, Bali, Enikö, Lamb, Oliver D., Barnie, Talfan, Woods, Andrew W., Kjartansdóttir, Rikey, Stefánsson, Andri“…Lava fountains are a common manifestation of basaltic volcanism. While magma degassing plays a clear key role in their generation, the controls on their duration and intermittency are only partially understood, not least due to the challenges of measuring the most abundant gases, H(2)O and CO(2). …”

1746“…METHODOLOGY/PRINCIPAL FINDINGS: Endemic fluorosis induced by high concentrations of fluoride in water and soils is a major health problem in several countries, particularly in volcanic areas. Here we describe for the first time the features of endemic fluorosis in the Herculaneum victims of the 79 AD eruption, resulting from long-term exposure to high levels of environmental fluoride which still occur today. …”

Precipitation and percentage of rural population are also associated with critical areas. …”

The densities of many groups and the number of taxa (classes and phyla) of macroinvertebrates were significantly reduced at elevated CO(2) (425–1100 µatm) compared with control sites. …”

The timescales and mechanisms of assembly of the magma reservoirs that feed such eruptions as well as the durations and physical conditions of upper-crustal storage remain highly debated topics in volcanology. …”

The GRAIL inventory of lunar basins improves upon earlier lists that differed in their totals by more than a factor of 2. …”

Marine reptile faunas shifted from ichthyosauromorph-dominated to sauropterygian-dominated composition after the perturbation.…”
