The Weekly Volcanic Activity Report [1] is a cooperative project between the Smithsonian's Global Volcanism Program and the United States Geological Survey's Volcano Hazards Program. Notices of volcanic activity posted on the report website are preliminary and subject to change as events are studied in more detail. Detailed reports on various ...
Volcanoes of the World is a book that was published in three editions in 1981, 1994, and 2010 as a collaboration between volcanologists around the world, and the Smithsonian Institution's Global Volcanism Program (GVP).
The Mercato eruption (Pomici di Mercato) of Mount Vesuvius was a Plinian eruption that occurred around 8,010 ± 40 14C yr BP (8,890 ± 90 cal yr BP). [3] The Global Volcanism Program claims that the eruption had a Volcanic Explosivity Index (VEI) of 5, [1] while Zanella et al. (2014) estimate it had a VEI of 6. [2]
The global dimming through volcanism (ash aerosol and sulfur dioxide) is quite independent of the eruption VEI. [ 104 ] [ 105 ] [ 106 ] When sulfur dioxide (boiling point at standard state : -10 °C) reacts with water vapor, it creates sulfate ions (the precursors to sulfuric acid ), which are very reflective; ash aerosol on the other hand ...
There are 100 volcanoes in the Philippines listed by the Smithsonian Institution's Global Volcanism Program (GVP) at present, [6] of which 20 are categorized as "historical" and 59 as "Holocene". [6] The GVP lists volcanoes with historical, Holocene eruptions, or possibly older if strong signs of volcanism are still evident through thermal ...
Eruptions and short-lived islands have been reported as far back as 1781, according to the Global Volcanism Program. [2] In December 1967 an eruption produced another short-lived island, [3] which disappeared by the end of 1968. [1] An eruption in 1979 discharged large amounts of pumice, and formed an island 16km in diameter. [4]
The catastrophic June 1991 eruption, which formed a caldera, later filled by a crater lake, had global environmental effects. ... Global Volcanism Program
