A Proposal for Systematisation of Vulnerability Elements and Parameters in Volcanic Risk Assessment
This work is part of the broader context of volcanic risk assessment, focusing on the identification, characterisation, and systematisation of the...

Sulfur in the Tephra of the ca. 1500 BP Opala Eruption, Kamchatka
AbstractSulfur-containing ejecta of Plinian-type eruptions can be transported to great distances in gas pores of ash particles. The mean...

Silicic conduits as supersized tuffisites: Clastogenic influences on shifting eruption styles at Cordón Caulle volcano (Chile)
Understanding the processes that drive explosive-effusive transitions during large silicic eruptions is crucial to hazard mitigation. Conduit models...

The Volcanic Geoheritage of El Teide National Park (Tenerife, Canary Islands, Spain)
El Teide National Park on the island of Tenerife (Canary Islands) is home to one of the most spectacular volcanic landscapes in the world. Although...

On the rise: using reentrants to extract magma ascent rates in the Bandelier Tuff caldera complex, New Mexico, USA
The Bandelier Tuff is the result of two subsequent caldera-forming eruptions of similar volume and composition which produced the Otowi (1.61 Ma) and...

Volcanological Features of Terceira Island (Azores): A Field Approach Around Hazards
Terceira Island (400 km2 area and the second most inhabited of the archipelago) comprises four polygenetic volcanoes with caldera (Cinco Picos,...

An Overview of the Large-Magnitude (VEI 4) Eruption of Merapi in 2010
The VEI 4 eruption in 2010 was the worst volcanic disaster at Merapi in 80 years.The unusual size and dynamics of the eruption, the rapid...

A data-driven approach to assess the role of the groundwater conditions in triggering shallow landslides initiating with frictional failure
In the Campania region (southern Italy), slo** pyroclastic surfaces in partially saturated conditions are frequently affected by flow-like...

The Godean Debris Avalanche Deposit From a Sector Collapse of Merapi Volcano
Debris avalanche deposits are products of large sector collapses of composite volcanic cones. Horseshoe-shaped craters open downslope to a hummocky...

The Central Kenya Rift Basins (Nakuru-Elmenteita-Naivasha)
The seven-million-year-old Central Kenya Rift was initially filled with Miocene flood phonolite and Mio-Pliocene trachyte and ash flows. During the...

No single model for supersized eruptions and their magma bodies
Supereruptions are the largest explosive volcanic eruptions on Earth. They generate catastrophic, widespread ash-fall blankets and voluminous...

Evolution of magma decompression and discharge during a Plinian event (Late Bronze-Age eruption, Santorini) from multiple eruption-intensity proxies
We have coupled three independent methods to investigate the time evolution of eruptive intensity during the sub-Plinian and Plinian phases of the...

Magnesium isotopes of chlorite-rich hydrothermal sediments in the Okinawa Trough and indications for Mg cycle
Seafloor hydrothermal systems play a significant role in the oceanic Mg cycle due to ubiquitous deposits of secondary Mg-rich clays during the strong...

Facies architecture, geochemistry and petrogenesis of Middle Triassic volcaniclastic deposits of Mt. Ivanščica (NW Croatia): evidence of bimodal volcanism in the Alpine-Dinaridic transitional zone
During the Middle Triassic, intensive volcanic activity took place along the eastern margin of Pangea, including the Greater Adria promontory, due to...
-
Stressful crystal histories recorded around melt inclusions in volcanic quartz
Magma ascent and eruption are driven by a set of internally and externally generated stresses that act upon the magma. We present microstructural...

Assessing volumes of tephra fallout deposits: a simplified method for data scarcity cases
A new method for assessing volumes of tephra deposits based on only two thickness data is presented. It is based on the assumptions of elliptical...

Paleomagnetic evidence for episodic construction of the Mamiyadake tephra ring
Tephra rings that surround maar craters are typically inferred from field observations to have been emplaced rapidly over a time period of days to...

Multiple Landslides in an Area Draped in Volcanic Matters: The Dual Impacts of Rains and Earthquakes
The devastating 2018 Hokkaido Eastern Iburi Earthquake, with a moment magnitude (Mw) of 6.7, inflicted significant damage in the eastern part of...

A Textural Perspective on the Magmatic System and Eruptive Behaviour of Merapi Volcano
Quantitative textural analysis of crystals, including their number density, shapes, sizes, overall abundance and size distribution can be used to...
