Size-distribution of scoria cones within the Eğrikuyu Monogenetic Field (Central Anatolia, Turkey)
26 May 2018 | Contributor(s): Göksu USLULAR, Gonca Kuşcu, Arda Arcasoy
Eğrikuyu Monogenetic Field (EMF) is one of the five clusters of monogenetic volcanoes in Quaternary Central Anatolian Volcanic Province (CAVP). EMF consists mainly of scoria cones and a few maars (e.g. Kutören, Obruk). Previous studies on monogenetic volcanoes of CAVP mainly focused on...

Spherulites and thundereggs from pitchstones of the Deccan Traps: geology, petrochemistry, and emplacement environments
18 Sep 2013 | Contributor(s): Pooja Vinod Kshirsagar
Spherulites and thundereggs are rounded, typically spherical, polycrystalline objects found in glassy silicic rocks. Spherulites are dominantly made up of radiating microscopic fibers of alkali feldspar and a silica mineral (commonly quartz). They form due to heterogeneous nucleation in highly...

Structural architecture and the episodic evolution of the ediacaran Campo Alegre Basin (southern Brazil): Implications for the development of a synorogenic foreland rift and a post-collisional caldera volcano
09 Apr 2021 | Contributor(s): Lucas Martins Lino, Francy Roxana Quiroz-Valle, Vinicius Abud louro, Miguel Ângelo Stipp Basei, Silvio Roberto Farias Vlach, Mathias Hueck, Patricio Rodrigo Montecinos Munõz, Sérgio Brandolise Citroni
During the last decades, tectonic models provided new insight into the evolution of the Luis Alves, Curitiba, and Paranaguá terranes, which are all limited by thrust and transpressive shear zones, nowadays outcropping only as deep crustal horizons and presenting poorly known lateral...

Supplementary material for Newhall and Pallister (2014) Using multiple data sets to populate probabilistic volcanic event trees
27 Sep 2017 | Contributor(s): Chris Newhall, John S Pallister
For probabilistic forecasting in volcanology, two widely used methods are the Cooke method (Aspinall and others) and BET-EF (Marzocchi and others). The paper noted in the title, in Papale P (ed), Volcanic Hazards, Risks and Disasters. Academic Press, describes...

Timescales of mingling in shallow magmatic reservoirs
12 Jun 2015 | Contributor(s): Chiara Paola Montagna, paolo papale, antonella longo
Arrival of magma from depth into shallow reservoirs has been documented as one of thepossible processes leading to eruption. Magma intruding and rising to the surface interacts with thealready emplaced, degassed magmas residing at shallower depths, leaving chemical signatures inthe erupted...

Towards a probabilistic scheme: How can we recognize and track non-magmatic unrest and related hazards?
18 Feb 2014 | Contributor(s): dmitri rouwet, Laura Sandri, Warner Marzocchi, Jo Gottsmann
Eruption forecasting is a major goal in volcanology. The intrinsic complexity and non-linearity of volcanic systems has recently led to an intertwining of deterministic to probabilistic eruption forecasting methods. However, many volcanoes often pass states of non-eruptive and non-magmatic unrest...

Towards the reconstruction of the shallow plumbing system of the Barombi Mbo Maar (Cameroon) Implications for diatreme growth processes of a polygenetic maar volcano
30 Aug 2015 | Contributor(s): CHAKO TCHAMABE Boris, Takeshi Ohba, Gabor Kereszturi, Karoly Nemeth, Aka Festus Tongwa, Dieudone Youmen, Isabel Meza, Yasuo Miyabuchi, Seigo Ooki, Greg Zinkeng Tanyileke, Hell Joseph Victor
Understanding the mechanisms involved in the formation of maars and their diatreme growth processes has been a subject of contention. While there is no direct evidence of the presence of diatremes beneath most of the young maars, their existence is inferred based on the amount and type of country...

VUELCO deliverable 7.5: Guidelines for the best practice of scientific management of volcanic unrest
09 Sep 2015 | Publications | Contributor(s): dmitri rouwet
Volcanic eruption forecasting and hazard assessment are multi-disciplinary processes with scientific and social implications. Our limited knowledge and the randomness of the processes behind a volcanic eruption yields the need of quantifying uncertainties on volcano dynamics. With deterministic...
