Surface wave, ambient noise and full waveform research group

The Surface Wave Research Group is mainly focused on the surface wave properties and new related methodologies to explore the Earth interiors.

The group is led by Helle Pedersen, Irene Molinari, florian Fuchs and Andrea Morelli.

Exciting science will be carried on during this unprecedented experiment: the data hold great promise, the scientific group is wide and excellent, and we are all confident that our new results will bring better understanding of the structure and geodynamics of the region. New collaborations, exchange new ideas are the main purposes of the group.

You can join the Research Group activities subscribing the group mailing list.

Research Group meetings

Second Surface Wave research group meeting (Vienna, 16/17.11.2017)

The Second Surface Wave RG meeting was held in Vienna on the 16 and 17 November 2017, hosted by University of Vienna, Geozentrum and organized by Helle Pedersen, Florian Fuchs and Andrea Morelli.

Two thirds of the 24 participants (from 11 organisations) were Ph.D. students or young researchers, contributing to the overarching goal of the Working Group to create networking and collaborations between young excellent researchers in seismology in Europe. The group shared recent results from processing of AlpArray data or other datasets, ranging from local or European scale isotropic and anisotropic seismic imaging, new  methodology in surface wave processing, or studies of surface wave propagation.

A special effort was made to present data quality and retrievement of AlpArray data.

First Surface Wave research group meeting (Bologna, 17/18.11.2016)

 

The First Surface Wave RG meeting was held in Bologna on the 17 and 18 November 2016, hosted by INGV Bologna (Via Donato Creti 12), organized by Andrea Morelli, Helle Pedersen, Tomas Meier and Irene Molinari

Aims

The declared objectives to exchange ideas and talk about what science perspectives AlpArray is opening, to see what are the main open questions, to discuss about possible collaborations, to create scientific contacts between institutes and researchers, with special emphasis on younger colleagues.

The workshop formula was based on short contributions, from all the participants, on surface wave propagation, analysis, inversion, previous and background studies (including the wider Alpine area, extending to Europe, the Balkans, the Mediterranean), planned studies. 


Meeting program
