Midland Valley - the structural geology experts

Università di Pavia

University of Pavia, Italy, has been a long-term user of Midland Valley software and joined the Academic Software Initiative (ASI) straight after its inception. On their most recent renewal they opted for our Standard Academic Package of 20 Move Licenses to sit on a computer network.

2010/2011

Move was used both for teaching at different levels and for research projects.

Second year BSc student have been introduced to Move through a number of exercises of balancing and restoring sections during the course “Geological structures and their interpretation” while some Ph.D students of the Department used Move in their research topics.

 

Returned Material and Examples of Usage

Siwalik_3D model with hypocenters: in this model the Deparment collected published cross sections and maps of the Siwalik foreland (frontal Himalaya region). Then plotted on the model the hypocenters of the earthquakes coming from instrumental seismicity. The goal is to verify if the seismic activity concentrates along a fault or a group of faults. The model presented here is part of an ongoing research project and will be improved and completed through time when they have other sections and more seismic data.

Northern Italy: this model was realized during a research project devoted to the analysis of the seismic risk in the Northern Italy. They plotted and merged maps and cross sections. The red surfaces are the main faults taken from the Database of the Individual Seismogenic Sources of the I.N.G.V (National Institute of Geophysics and Volcanology), see www.ingv.it. The other coloured surfaces are the three main aquifers of the Po Plain, representing isochronal surfaces (respectively 0.35My for A; 0.65 My for B and 3.9 My for C).

Analogue model: in this model they inserted all the pictures of the internal sections of an analogue model built to recreate the structural pattern of the central Po Plain (in the parts where the Northern Apennines and the Southern Alps outermost buried fronts are close). Some of the sections have been digitized for a following 3D reconstruction (following model).

3D Analogue Model: this model has been created from the digitization of the internal sections of the previous analogue model. They reconstructed the main faults and some of the stratigraphic layers in order to check how the displacement varies along strike. On the top of the model we inserted the picture of the model topography.

2009-2010

 

The licenses were used for scientific research projects. In particular projects about the seismic risk assessment in collaboration with the I.N.G.V (National Institute of geophysics and volcanology) and with the Prime Minister Bureau (DPC, Civil Protection Department). Other projects within the Earth Science Department were in regard to the analogue modelling technique applied to structural reconstructions of the Po Plain subsoil (Northern Italy) and the kinematic evolution of the surrounding thrust belts (Northern Apennine and Southern Alps).

Move is mainly used for seismic line interptation, 3D reconstructions fusing lines (mainly parallel geological cross section) and for measuring different paramenters on pictures coming from analogue models or to digitize them and then reconstruct them in 3D (for example to reconstruct the internal fault pattern or the changes on the surface of the model while deformation increases).

2008/2009

Move was used in Undergraduate teaching: 10%; MSc classes: 10%; Ph. D courses: 30%; Research projects: 50%.

The Research Unit began scoping the projects for interpreting seismic sections, reconstruct in 3D the architecture of the Po Plain (Northern Italy) and merge in an unique 3D model different kind of data and informations.  Move was used to reconstruct in 3D the models (starting from the digitization of the pictures taken), to present the models to colleagues, other research unit researchers, for reports about the project etc and also for quantitative analysis on the models. Also undergraduate, MSc and Ph.D students (about 10 during the year) involved in the project for seismic interpretations, analogue models analysis or 3D reconstructions used the software.
