THE STUDY OF EPHEMERAL OUTCROPS: THE EXAMPLE OF THE GARROTXA VOLCANIC FIELD
04 Sep 2013 | Contributor(s):: Xavier Bolos, Llorenç Planaguma, Joan Marti
The study of ephemeral outcrops is an important tool to reconstruct the geology of highly urbanised areas in which increasing construction and occupation of soil difficult direct observations. During the last decade, the Natural Park of the Garrotxa Volcanic Field (NE Spain) has undertaken a...

A PROBABILISTIC METHOD TO CALCULATE VOLCANIC SUSCEPTIBILITY
04 Sep 2013 | Contributor(s):: Steffania Bartolini, A. Cappello, Joan Marti, Rosa Sobradelo, Stephanie Barde-Cabusson
In modern volcanology one of the most important aim is to perform hazard maps simulating different eruptive scenarios. The first step is to evaluate the spatial distribution of future vents, based on the past behavior of the studied area. Previous work were done using the kernel density...

STRUCTURAL CONTROLS ON MONOGENETIC VOLCANISM: THE GARROTXA VOLCANIC FIELD CASE STUDY
04 Sep 2013 | Contributor(s):: Xavier Bolos, Stephanie Barde-Cabusson, Jo Gottsmann, Joan Marti, Dario Pedrazzi, Llorenç Planaguma, Antonio Camacho, Adelina Geyer Traver, Erika Ronchin
The factors controlling the precursory activity in monogenetic volcanic fields are still poorly understood, which makes that eruption forecasts in these systems is not very accurate. The fact that in monogenetic volcanism each eruption has a different vent suggests that volcanic susceptibility...

HASSET: A probability event tree tool to evaluate future eruptive scenarios based on Bayesian Inference. Presented as a plugin for QGis
04 Sep 2013 | Contributor(s):: Rosa Sobradelo, Steffania Bartolini, Joan Marti
Event tree structures constitute one of the most useful and necessary tools of modern volcanology to assess the volcanic hazard of future eruptive scenarios. They are particularly relevant to evaluate long- and short-term probabilities of occurrence of possible volcanic scenarios and their...

COMUNICATION PROTOCOLS QUESTIONNAIRE
04 Sep 2013 | Contributor(s):: Alicia Felpeto, Joan Marti, Rosa Sobradelo
Barcelona Workshop 2013:Within WP8 activities, a questionnaire has been designed to collect information of the way the scientists and decision-makers transmit the information between them and to the population/media. We hope it will help us to identify different communication structures and...

GEODYNAMIC CONSTRAINTS OF CANARIAN VOLCANISM
04 Sep 2013 | Contributor(s):: Joan Marti, Adelina Geyer Traver
Barcelona Workshop 2013 The intimate relationship between tectonism and magmatism is evident in all volcanic environments, where magma production, magma ascent rate, loci of volcanic activity, and the style of volcanic activity, are directly dependent on the regional/local tectonic...

INTERPRETING TREMOR CHANGES DURING 2011-2012 EL HIERRO ERUPTION (CANARY ISLANDS)
04 Sep 2013 | Contributor(s):: Marta Tarraga, Joan Marti, Roberto Carniel, Rafael Abella, Carmen López
Barcelona Workshop 2013One of the most informative geophysical signals that can be recorded on a volcano is the tremor, which has been used as a precursor of eruptive activity as well as a marker of changes of the eruption dynamics. In this contribution we analyse the strong tremor signal that...
