VUELCO deliverable 7.5: Guidelines for the best practice of scientific management of volcanic unrest

09 Sep 2015 | 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...

Cost/benefit Analysis: Guidelines for quantitative protocols for volcanic risk reduction

24 Aug 2015 | Contributor(s): dmitri rouwet

The goal of this deliverable is to provide guidelines that may allow scientists and decision makers tobridge the gap between volcanological knowledge and a rational decision making. Part of thecontent of this document has been published on the paper W. Marzocchi, C.G. Newhall, G. Woo(2012). The...

Towards a probabilistic scheme: How can we recognize and track non-magmatic unrest and related hazards?

18 Feb 2014 | Publications | 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...

VOLADA – the first collaborative data base on Volcanic Lakes

23 Aug 2013 | Presentations | Contributor(s): dmitri rouwet, Veronica Chiarini

There are more volcanic lakes on Earth than previously thought. The here presented data base is first in its kind and compiles the available information on ~340 volcanic lakes worldwide. It aims to become a complete and interactive tool, in which researchers can add, extract and use data in a...

A probabilistic framework to quantify hazard related to volcanic lakes

23 Aug 2013 | Presentations | Contributor(s): dmitri rouwet, Laura Sandri, raul mora-amador

The presence of a volcanic lake increases the probability of certain types of volcanic hazard. So far, this topic has only been approached in a purely deterministic way, e.g.: phreatic-phreatomagmatic eruption behavior, dynamics of Nyos-type gas bursts and gas accumulation and dispersion, models...

Numerical simulations (TOUGH2) to quantify crater lake seepage: a case study for Laguna Caliente, Poás Volcano (Costa Rica)

23 Aug 2013 | Presentations | Contributor(s): massimo nespoli, micol todesco, dmitri rouwet, maurizio bonafede, raul mora-amador

Volcanic lakes are different from the common reservoirs of meteoric origin because of the interaction with the hydrothermal system of the volcano. The hot fluids (gas + liquid) of volcanic origin rise through the bottom of the lake resulting in strong acidic water and a variable temperature...

Qualitative insights (Cl, D) into evaporative degassing from active crater lakes: theoretical background and practical tools

23 Aug 2013 | Presentations | Contributor(s): dmitri rouwet, Takeshi Ohba

This work provides the theoretical background and necessary practical tools to study one of the most spectacular natural features: vigorous evaporation from active crater lakes. We will give qualitative insights (lake water chemical –Cl content, and isotopical composition) rather than quantify...

Science & Arts workshops to increase volcanic risk awareness: Chapultenango, near El Chichón volcano (Chiapas, Mexico)

23 Aug 2013 | Presentations | Contributor(s): dmitri rouwet, marta iorio, Demetrio Polgovsky

This independent and informal study is based on good-will, common sense, working ethics and morality, rather than on a pre-meditated education method or strategy, with the goal to increase the public awareness of volcanic risk in the Zoque indigenous community of Chapultenango, near El Chichón...

BET_EF application during the Colima Exercise in Nov. 2012

26 Apr 2013 | Miscellaneous | Contributor(s): Laura Sandri, dmitri rouwet

This short document describes all the settings for BET EF for Colima volcano that were decided BEFORE the beginning of the Colima exercise. The settings were decided by Laura Sandri and Dmitri Rouwet, stemming from 2 reports that we had received from Raul Arambula and Gabriel Reyes of UNAM. The...
