Global influence of the AD1600 eruption of Huaynaputina, Peru
Article Abstract:
Global temperatures can drop following a volcanic eruption, and this appears to be linked to sulfuric acid produced in the stratosphere. Studies of the impact of eruptions on climate change have used tree-ring and ice-core measurements. The inventory of eruptions is still being developed. The Huaynaputina eruption in Peru, 1600, appears to have been one of the biggest in history, and was similar to or greater than the 1883 Krakaau eruption. It can be assessed through examining tephra deposits in Antarctica.

Ice in the 1994 Rabaul eruption cloud: implications for volcano hazard and atmospheric effects
Article Abstract:
The analysis of the volcanic clouds, obtained during the September 1994 eruption of Rabaul volcano, Papua New Guinea, reveals that they consist of slightly less than 2 million tons of ice and low levels of sulphur dioxide. The rarity of the clouds is that they cause the sea water to enter the volcanic vent and it supports the eruption column. The volcanic ash is masked by the ice leading to the difficulty in designing airborne ash detection systems for aviation safety.

Generation of hydrothermal megaplumes by cooling of pillow basalts at mid-ocean ridges
Article Abstract:
The formation of new undersea crust is accompanied by high-temperature hydrothermal activity, causing either chronic plumes or transient hydrothermal megaplumes, the latter located up to 1,000 mt above the sea floor. The origin of hydrothermal megaplumes remains unknown but a new theoretical model suggests that the cooling of pillow basalts can release the heat flux necessary for their generation.
