Transforming a volcanic rock powder waste into an efficient adsorbent to remove dyes (acid green 16 and acid red 97) and metals (Ag+, Co2+, and Cu2+) from water
This study searched for the best synthesis route for producing an adsorbent from the alkaline fusion of volcanic rock powder waste. The samples...

The impact of livestock activities and geochemical processes on groundwater quality of fractured volcanic rock aquifer: Lake Çıldır watershed (NE Turkey)
This paper presents the impact of livestock activities and geochemical processes on the water quality of a fractured volcanic rock aquifer in the...

Young volcanic terrains are windows into early microbial colonization
Volcanic eruptions generate initially sterile materials where biological processes are absent, allowing for the fresh colonization by new organisms....

Volcanic rock powder residues as precursors for the synthesis of adsorbents and potential application in the removal of dyes and metals from water
The present study verified the potential of volcanic rock powder residues originating from the extraction of semi-precious rocks in the state of Rio...

Brief and intensive volcanic emissions from Ontong Java Nui heralded Oceanic Anoxic Event 1a
The volcanic episode that formed Ontong Java Nui (OJN) in the western Pacific ~ 120 million-year-ago is thought to have triggered Oceanic Anoxic...

Topsoil’s magnetic and electrical properties in a volcanic and tropical region
Environmental monitoring by measuring topsoil’s magnetic and electrical properties is one practical, quick, and low-cost approach. This method has...

Deep seafloor hydrothermal vent communities buried by volcanic ash from the 2022 Hunga eruption
Mass mortality of marine animals due to volcanic ash deposition is present in the fossil record but has rarely been documented in real time. Here,...

Failure of load-bearing dyke networks as a trigger for volcanic edifice collapse
Most large ocean-island volcanoes are gravitationally unstable. Some deform slowly, forming long-lived slumps, while others collapse and generate...

Volcanic impact on terrestrial and aquatic ecosystems in the Eastern Mediterranean
Natural disturbances such as volcanic eruptions provide a unique opportunity to study past ecological dynamics. Here we illustrate the response of...

Evaluation of quality and hydrogeochemistry of rock aquifers in Jurong Formation at Southern Johor Bahru, Malaysia
Jurong Formation underlies part of Southern Johor Bahru which comprises well cemented and consolidated volcanic-sedimentary rocks. The study aims to...
-
Decadal-to-centennial increases of volcanic aerosols from Iceland challenge the concept of a Medieval Quiet Period
Existing global volcanic radiative aerosol forcing estimates portray the period 700 to 1000 as volcanically quiescent, void of major volcanic...

Decoding the state of stress and fluid pathways along the Andean Southern Volcanic Zone
Decoding means decrypting a hidden message. Here, the encrypted messages are the state of stress, fluid pathways, and volcano tectonic processes...

Chemolithotrophic biosynthesis of organic carbon associated with volcanic ash in the Mariana Trough, Pacific Ocean
Volcanic ash is a major component of marine sediment, but its effect on the deep-sea carbon cycle remains enigmatic. Here, we analyzed mineralogical...

A Non-contact Method for Measuring the Size Distribution of Rock Blocks Based on Image Processing Technology
Due to the unique volcanic geological conditions in the Changbai Mountain area, debris flow disasters occur frequently and show an increasing trend,...

Phreatic volcanic eruption preceded by observable shallow groundwater flow at Iwo-Yama, Kirishima Volcanic Complex, Japan
It is difficult to forecast phreatic eruptions because they are often characterised by an abrupt onset at shallow depths beneath volcanoes. Here we...

Exploring Rare Earth Element behavior in the Mount Etna volcanic aquifers (Sicily)
This study presents the first data on REY (Rare Earth Elements plus Yttrium) in the aquifer of Mount Etna (Sicily, Italy). Patterns normalized to...

Hydrogeochemical processes and groundwater evolution in complex volcanic highlands and alluvio-lacustrine deposits (Upper Blue Nile), Ethiopia
Lake Tana basin encompasses a wide regional volcanic aquifer system, in the northwestern highlands of Ethiopia. It has significant water resource...

Magnetic susceptibilities of surface sediments from estuary rivers in volcanic regions
Estuaries have very complex mechanisms because they are influenced by seawater intrusion, which causes enrichment of contaminants in the maximum...
