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...

STRUCTURAL CONTROLS OF MONOGENETIC VOLCANISM

04 Sep 2013 | Contributor(s): Adelina Geyer Traver

The factors controlling the precursory activity in monogenetic volcanic fields are still poorly understood, which means that eruption forecasts in these systems are not very accurate. The fact that in monogenetic volcanism each eruption has a different vent suggests that volcanic susceptibility...

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...

Tephra 2014 - Maximizing the potential of tephra for multidisciplinary science

09 Jan 2014 | Workshops | Contributor(s): Steven Kuehn, Solene Pouget, Marcus I Bursik

Tephra deposits are used by diverse communities: volcanologists, petrologists, tephrochronologists, paleoclimatologists, paleoecologists and archaeologists. To perhaps be too reductionist, volcanologists are generally interested in tephra to understand eruption behavior, frequency, and hazards;...

Best practices in tephra collection, analysis, and reporting: Leading toward better tephra databasesThis is a page for the Tephra 2017 workshop, held in Portland, OR, 19 August 2017.  The workshop was a follow-on to the Tephra 2014 workshop, held 3-7 August 2014, also in...

Tephra Impact Lab - Taupo Volcano

06 Dec 2011 | Educational Materials | Contributor(s): Tom Wilson, Leah Michelle Courtland

This lab requires students to produce a pre-eruption tephra risk assessment for Taupo volcano, using Tephra2. It requires students to consider the eruptive history of Taupo volcano and a volcanic unrest scenario is provided, so that students must decide what magnitude and style of eruption is...

Tephra inversion with Tephra2 and the Metropolis-Hastings algorithm

21 Jun 2020 | Offline Tools | Contributor(s): Qingyuan Yang, E Bruce Pitman, Marcus I Bursik, Susanna Jenkins

We couple the Metropolis-Hastings algorithm (Hastings, 1970) with the volcanic ash transport model Tephra2 (Bonadonna et al, 2005; 2010), and present the coupled algorithm as a new method to estimate the Eruption Source Parameters (ESPs) of volcanic eruptions based on mass per unit area...

Tephra isopach, extent and volume calculation in R
