Dynamics and mass balance of El Chichón crater lake, Mexico [PDF]

open access: yesGeofísica Internacional, 2004
The mass balance of El Chichón crater lake is controlled by precipitations, evaporation and seepage through the lake bottom. The main non-meteoric source of water and Cl for the lake is a boiling spring (Soap Pool) discharging saline and neutral water ...

A new lake in the Korbut Crater of Ebeko Volcano (Paramushir Island, Kuriles Islands)

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
The paper reports the appearance of a new crater lake on the Ebeko volcano. There has been no thermal lake within the Northern Crater since mid-2006. The last eruption began on October 19, 2016 and ended on November 19, 2021.

Insights into the recurrent energetic eruptions that drive Awu, among the deadliest volcanoes on Earth [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2020
The little-known Awu volcano (Sangihe Islands, Indonesia) is among the deadliest, with a cumulative death toll of 11 048. In less than 4 centuries, 18 eruptions were recorded, including two VEI 4 and three VEI 3 eruptions with worldwide impacts ...

Selected Crater and Small Caldera Lakes in Alaska: Characteristics and Hazards

open access: yesFrontiers in Earth Science, 2022
This study addresses the characteristics, potential hazards, and both eruptive and non-eruptive role of water at selected volcanic crater lakes in Alaska. Crater lakes are an important feature of some stratovolcanoes in Alaska.

Patterns in benthic biodiversity link lake trophic status to structure and potential function of three large, deep lakes. [PDF]

open access: yesPLoS ONE, 2015
Relative to their scarcity, large, deep lakes support a large proportion of the world's freshwater species. This biodiversity is threatened by human development and is in need of conservation.

Fluid-mineral dynamics at the Rincón de la Vieja volcano—hydrothermal system (Costa Rica) inferred by the study of major, minor and rare earth elements in the hyperacid crater lake

open access: yesFrontiers in Earth Science, 2023
Volcanic lakes are complex natural systems and their chemical composition is related to a myriad of processes. The chemical composition of major, minor, Rare Earth Elements (REE) and physico-chemical parameters at the hyperacid crater lake of Rincón de ...

Unexpected diversity found within benthic microbial mats at hydrothermal springs in Crater Lake, Oregon

open access: yesFrontiers in Microbiology, 2022
Crater Lake, Oregon is an oligotrophic freshwater caldera lake fed by thermally and chemically enriched hydrothermal springs. These vents distinguish Crater Lake from other freshwater systems and provide a unique ecosystem for study.

Lacustrine sedimentation by powerful storm waves in Gale crater and its implications for a warming episode on Mars

open access: yesScientific Reports, 2023
This investigation documents that the Rugged Terrain Unit, the Stimson formation, and the Greenheugh sandstone were deposited in a 1200 m-deep lake that formed after the emergence of Mt. Sharp in Gale crater, Mars, nearly 4 billion years ago.

Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 103-116., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
