The optical properties of the stratospheric aerosol layer perturbation of the Hunga Tonga–Hunga Ha'apai volcano eruption of 15 January 2022 [PDF]

Atmospheric Chemistry and Physics
The Hunga Tonga–Hunga Ha'apai volcano violently erupted on 15 January 2022 and produced the largest stratospheric aerosol layer perturbation of the last 30 years.

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, Volume 73, Issue 5, Page 1331-1351, August 2026.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Reversal of the ITCZ Shift During the Satellite Era

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract A southward shift of the Intertropical Convergence Zone (ITCZ) during the latter half of the 20th century has been primarily attributed to interhemispheric differences in anthropogenic aerosol forcing. However, in recent decades anthropogenic aerosol emissions have declined, particularly over Northern Hemisphere (NH).

Lidar measurements of stratospheric aerosol content and depolarization ratios after the eruption of El Chichón volcano: measurements at Nagoya, Japan

Geofísica Internacional, 1984
Después de la erupción de "El Chichón", se observó un enorme aumento en la dispersión de fondo de la luz desde la capa de aerosol estratosférico, utilizando un lidar de rubí en Nagoya, Japón (35ºN, 137ºW).En la parte inferior de la capa principal de ...

Volcanic Forcing Amplifies Extreme Wet‐to‐Dry in Pre‐Flood South China Driven by Internal Variability

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Dry‐wet whiplash events profoundly impact society and the environment, yet their attribution remain poorly understood. This study reveals that the unprecedented interannual wet‐to‐dry transition (return period: 979.2 years) in South China's 1962–1963 pre‐flood season is co‐driven by internal variability and volcanic forcing.

Major and trace element geochemistry of neutral and acidic thermal springs at El Chichón volcano, Mexico

, 2008
Four groups of thermal springs with temperatures from 50 to 80 °C are located on the S–SW–W slopes of El Chichón volcano, a composite dome-tephra edifice, which exploded in 1982 with a 1 km wide, 160 m deep crater left.

Fluid Geochemistry of El Chichón Volcano-Hydrothermal System

, 2015
El Chichón volcano hosts an intense hydrothermal system with surface manifestations consisting of an acid lake, steam vents, steam-heated boiling pools, mud pools and boiling springs in the crater, as well as several hot springs located on the outer ...

Sulfur Exposure for Airplane Passengers From Stratospheric Aerosol Injection

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Injection of sulfur dioxide to create a stratospheric sulfate aerosol cloud is the most studied method of climate intervention. It has been suggested that airplanes be used at high latitudes to create such a cloud at lower altitudes. Commercial airplanes routinely fly at altitudes of 11 km in the Arctic, and therefore passengers could be ...

Social vulnerability of Esquipulas Guayabal town in regard to hazards from El Chichón volcano, México

Natural Hazards Research
El Chichón, the most active volcano in the Chiapaneco Volcanic Arc of southeastern Mexico, erupted explosively in March–April 1982. The eruption caused extensive environmental destruction, significant loss of life, and profound social upheaval.

Post‐Eruption Tropical Cyclone Genesis Potential Change Over the Western North Pacific Modulated by Initial Oceanic Conditions

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract How tropical cyclone (TC) frequency may change following volcanic eruptions remains debated, owing to limited contemporary eruption samples. Using last‐millennium multi‐member simulations with CESM, we show that post‐eruption TC genesis potential over the western North Pacific consistently decreases during the storm season following extremely ...
