Using palaeoecological techniques to understand the impacts of past volcanic eruptions
Quaternary International, 2017 Large volcanic eruptions may have major impacts on ecosystems through their physical, chemical and climatic affects. These impacts are stochastic and because the largest, most damaging volcanic events have not occurred in the recent past there is ...

Constructional Volcanic Edifices on Mercury: Candidates and Hypotheses of Formation [PDF]
, 2018 Mercury, a planet with a predominantly volcanic crust, has perplexingly few, if any, constructional volcanic edifices, despite their common occurrence on other solar system bodies with volcanic histories.

Report of the panel on volcanology, section 4 [PDF]
Two primary goals are identified as focal to NASA's research efforts in volcanology during the 1990s: to understand the eruption of lavas, gases, and aerosols from volcanoes, the dispersal of these materials on the Earth's surface and through the ...

Distinct winter North Atlantic climate responses to tropical and extratropical eruptions over the last millennium in PMIP simulations and reconstructions [PDF]
Climate of the PastLarge tropical (TROP) volcanic eruptions can influence North Atlantic climate by inducing a positive shift of the North Atlantic Oscillation (NAO), typically resulting in winter warming across northern Eurasia.

Nano-volcanic Eruption of Silver
Scientific Reports, 2016 AbstractSilver (Ag) is one of the seven metals of antiquity and an important engineering material in the electronic, medical, and chemical industries because of its unique noble and catalytic properties. Ag thin films are extensively used in modern electronics primarily because of their oxidation-resistance. Here we report a novel phenomenon of Ag nano-

Keeping watch over Colombia’s slumbering volcanoes [PDF]
, 2015 The Volcanological and Seismological Observatories of Manizales, Pasto and Popayan (Colombian Geological Survey) monitor and study the active volcanoes of Colombia using seismological, geodetic, geochemical and other techniques.

Nature, 1874 A PASSAGE in Nasmyth's work on the “Moon” suggests, as a consequence, an explanation of volcanic eruptions that I have often given in lectures. The point to be explained is, why they are sudden and intermittent. Processes of cooling and expansion are gradual.

Global monsoon precipitation responses to large volcanic eruptions
Scientific Reports, 2016 Climate variation of global monsoon (GM) precipitation involves both internal feedback and external forcing. Here, we focus on strong volcanic forcing since large eruptions are known to be a dominant mechanism in natural climate change.

Anticipating future Volcanic Explosivity Index (VEI) 7 eruptions and their chilling impacts
, 2018 Worst-case or high-end subduction-related earthquakes and tsunamis of 2004 and 2011 are painfully fresh in our memories. High-end subductionrelated volcanic eruptions have not occurred in recent memory, so we review historical and geologic evidence about
