How Does a Pinatubo‐Size Volcanic Cloud Reach the Middle Stratosphere?
Journal of Geophysical Research: Atmospheres, Volume 126, Issue 10, 27 May 2021., 2021 Abstract Volcanic explosions are the most critical replenishing mechanism of the stratospheric aerosol Junge layer. A fresh volcanic cloud comprises mostly sulfur‐bearing gases, volcanic ash, and water vapor. It is commonly assumed that only sulfate aerosols remain in an aged volcanic cloud.

Paleoceanography and Paleoclimatology, Volume 36, Issue 4, April 2021., 2021 Abstract Large volcanic eruptions are one of the dominant perturbations to global and regional atmospheric temperatures on timescales of years to decades. Discrepancies remain, however, in the estimated magnitude and persistence of the surface temperature cooling caused by volcanic eruptions, as characterized by paleoclimatic proxies and climate models.

On the likelihood of future eruptions in the Chilean Southern Volcanic Zone: interpreting the past century's eruption record based on statistical analyses [PDF]
, 2012 A sequence of 150 explosive eruptions recorded during the past century at the Chilean Southern Volcanic Zone (SVZ) is subjected to statistical time series analysis. The exponential, Weibull, and log-logistic distribution functions are fit to the eruption

Geophysical Research Letters, Volume 47, Issue 19, 16 October 2020., 2020 Abstract The relationship between volcanic stratospheric aerosol optical depth (SAOD) and volcanic radiative forcing is key for quantifying volcanic climate impacts. In their Fifth Assessment Report, the Intergovernmental Panel on Climate Change used one scaling factor between volcanic SAOD and volcanic forcing based on climate model simulations of the

A science & arts sensitization program in Chapultenango, 25 years after the 1982 El Chichόn eruptions (Chiapas, Mexico) [PDF]
, 2013 Volcanic risk perception may drastically decrease after eruptions and during periods of volcanic quiescence. Despite the fact that the adults in Chapultenango, a Zoque indigenous community near El Chichόn volcano (Chiapas, Mexico), lived through the 1982
