http://www.pubvolc.net/ PubVolc provides a new way for all members of the volcanology community to share their published research. PubVolc is free and is available to anyone with access to the internet, allowing poorly-resourced volcanologists to keep up-to-date with the latest volcanology...

Pyroclastic density currents and local topography as seen with the conveyer model

15 Apr 2014 | Contributor(s): Domenico M. Doronzo

Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...

Quantifying Causes of Arctic Amplification via Deep Learning based Time-series Causal Inference

23 Jul 2024 | Contributor(s): Sahara Ali, Omar Faruque, Yiyi Huang, Aneesh Subramanian, Nicole-Jienne Shchlegel, Md Osman Gani, Jianwu Wang, Josephine Namayanja (contributor)

The warming of the Arctic, also known as Arctic amplification, is led by several atmospheric and oceanic drivers. However, the details of its underlying thermodynamic causes are still unknown. Inferring the causal effects of atmospheric processes on sea ice melt using fixed treatment effect...

Sequential fragmentation/transport model applied to Irazu volcano, Costa Rica. Positive dispersion case

21 Mar 2015 | Contributor(s): Jose Brenes

Sequential fragmentation/transport model was applied to ash deposits of 1723 eruption of  Irazu volcano, Costa Rica.  Some 25% of the sub-populations showed positive dispersion values, which were associated to a new fractal dimension,. With the help of Mandelbrot fractal relationship...

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...
