Novel approach for time-dependent seismic hazard analysis and earthquake damage scenarios - Nohard

Principal Investigator: Emanuele Tondi
Research Unit Leaders: Miller Zambrano, Emanuele Tondi, Marco Materazzi, Andrea Dall’Asta

The present project proposes an innovative, integrated, multidisciplinary study aimed at defining an innovative timedependent seismic hazard assessment protocol, fundamental for the implementation of advanced and integrated strategy on seismic risk reduction and disaster management. This can lead to define structural design rules to ensure target safety levels considering time-dependent hazard models for short- and long-term time scales. The multidisciplinary approach includes three work packages (WPs): the first two WPs focus on defining the 3D geological/geophysical models and a new time-dependent seismic hazard assessment, whereas the third WP aims at the seismic risk evaluation.The main results will be used to develop new advanced time-dependent seismic risk protocols and hence to propose new structural design rules for time-dependent seismic hazard through sensitivity analysis and comparison of the most important parameters controlling both time dependent and time independent hazard models.The selected area for this study is located in the northern portion of Marche Region (Italy), along the Central Apennines, characterized by an intense historical seismicity which includes the Fabriano 1741 (Mw =6.2), Cagli 1781 (Mw 6.4) and Camerino 1799 (Mw =6.2) earthquakes, and most recently the recent seismic sequence started in 2016 (Amatrice, Visso, Norcia earthquakes, Mw max =6.5).

NOVEL APPROACHES IN EARTHQUAKES SCIENCE; FROM THE FIELD OBSERVATIONS TO THE MODELLING OF THE RESULTS
Crustal faults are complex natural systems whose mechanical properties evolve over time thus the understanding of the multi-scale, physical/chemical processes responsible for earthquakes and faulting requires considering phenomena that intersect different research fields, modelled with innovative techniques.
We support projects grounded on small- to large-scale seismically active fault systems, focussed on the understanding of the role of the most different parameters, in the earthquakes preparatory phase and deformation processes.

NEW APPROACH FOR SEISMIC HAZARD ANALYSIS AND EARTHQUAKE DAMAGE SCENARIOS
The definition of a new generation of time-dependent and deterministic seismic hazard evaluation procedures has the ambitious outcome of developing tools for predicting the time-space seismic sequences evolution, and the related ground-motion level, useful for the implementation of advanced integrated strategy for seismic risk reduction and disaster planning.
We support project that integrate the simulation of complex earthquake source and wave radiation processes with the aim to get reliable predictions of the variability of the strong ground motion around the causative fault system and a more accurate estimate of the expected distributions of engineering parameters in relation to the possible spectrum of earthquakes that may cause damages in the areas of interest.

APPROCCIO INTEGRATO PER LA VALUTAZIONE DEI RISCHI NATURALI, A SUPPORTO DEL MIGLIORAMENTO DELLA RESILIENZA RURALE E URBANA

In questo progetto proponiamo uno studio integrato e multidisciplinare per migliorare gli strumenti attualmente in uso per la prevenzione in ambito di terremoti, frane e alluvioni, innovando da un lato l’informazione di base necessaria e relativa alle pericolosità geologiche, dall’altro la valutazione del multi-rischio, sia su base architettonica che economica.
Il progetto ha l'ambizioso obiettivo di sviluppare su piattaforma digitale territoriale (Geographic Information System, GIS) strumenti innovativi per predire l'evoluzione delle pericolosità geologiche nello spazio e nel tempo e determinare il relativo grado di multi-rischio. I risultati saranno utilizzati per la definizione di nuove procedure di valutazione del rischio sia con metodi probabilistici che deterministici, utili per l'implementazione di una strategia integrata avanzata per la riduzione dello stesso e la predisposizione di indicatori di resilienza multidimensionali.
L'area individuata per questo studio ricade immediatamente a nord della zona colpita dalla recente crisi sismica (Terremoto di Amatrice, Norcia, Visso del 2016, Mw max =6,5), è situata lungo la porzione assiale dell'Appennino centro-settentrionale ed è in parte interessata dalla ricostruzione post-sisma 2016. Questa zona risulta caratterizzata da un’intensa sismicità storica, tra cui il terremoto di Fabriano del 1741 (Mw 6.2), di Cagli del 1781 (Mw 6.4) e di Camerino del 1799 (Mw=6.2).

3 SCHOLARSHIPS to carry out research activities at the INGV Division of Unicam

1. Broadband, high-sensitivity devices for environmental monitoring
Tutor: Prof. Fabio Marchesoni (Scuola Scienze e Tecnologie, 02-Fisica, FIS/03).
Co-Tutors: Prof. Gilberto Pambianchi (Unicam); Dr. Flavio Travasso (Unicam).

Interdisciplinary project for the prototyping and testing of a new class of multipurpose mechanical sensors for civil applications (accelerometers, gravimeters, inclinometers, etc.), characterized by enhanced broad-band sensitivity at low frequency. The project aims at developing a new type of platform based on concepts first introduced in the context of gravitational wave interferometry. Hardware improvements will revolve around four main tasks: (i) customized design for civil applications; (ii) selection of optimal fabrication materials; (iii) prototyping and on-site testing; and (iv) miniaturization.
As a first proof-of-concept of this strategy, we propose to monitor ongoing geomorphological processes, like those triggered by the earthquake that struck our community in 2016, or to assess the risks associated with the hydrogeological instability (e.g., landslides) of our region. In particular, we will test this new generation of mechanical sensors by monitoring the stability and deterioration of human artefacts (like residential buildings, bridges, dams, and historical heritage sites) against aging and environmental changes.
The main stakeholders of this initiative are, besides the agencies funding fundamental research in Italy and abroad, the policy-makers and cultural operators in charge of the post-seism reconstruction effort and, possibly, SME’s interested in developing and commercializing new high-precision instrumentation.

2. Shock features in major and accessory minerals due to impact vs. tectonic processes
Tutor: Prof. Gabriele Giuli (Scuola Scienze e Tecnologie, 04-Scienze della Terra, GEO/06)..
Co-Tutors: Dr. Lidia Pittarello (Museo di Storia Naturale di Vienna); Prof. Giovanni Pratesi (Unifi).

High strain-rate deformations can cause in situ melting of rocks, with the formation of nano- or micro-veins of pseudotachilites. On Earth, pseudotachilites are formed as a result of meteorite impacts, large landslides, and earthquakes. Recent studies have shown that the study of zircons microstructures could provide indications to distinguish pseudotachilites formed during meteorite impacts from those formed during earthquakes. Sede INGV UNICAM http://istituto.ingv.it/it/sede-unicam.html
In this project, several microstructures indicating shocks in minerals commonly used to provide indications on the degree of shock achieved during meteorite impact events will be studied; and the potential application of some microstructures in the same minerals will be assessed in the study of seismic pseudotachilites or by large landslides.
The shock features of minerals such as feldspar, quartz, zircons, apatites and quartz, will be studied in Earth impact breccias, shocked rocks, impact veins in meteorites, and pseudotachilites. Some of these minerals have shown shock features also in natural samples taken from seismic pseudotachilites, or in experimental samples simulating friction melting conditions. Laboratory experiments will also be carried out in order to reproduce the formation of pseudotachilites and then study the shock features in the minerals present within the pseudotachilite.
The data obtainable as part of this research project will be useful to provide information on the peak of stress to which the pseudotachilites related to fossil earthquakes have been subjected. These data may have implications for the study of past seismicity in selected geographical areas where pseudotachilites are found.

3. Fault interaction and the evolution of seismicity: the case study of the Central Apennines Fault System (CAFS)
Tutor: Prof. Emanuele Tondi (Scuola Scienze e Tecnologie, 04-Scienze della Terra, GEO/03).
Co-Tutor: Dr. Aybige Akinci (INGV-Roma)

Descrizione: Fault interaction and fault-growth by segment linkage represent fundamental processes controlling the evolution, in both time and the space, of fault systems. The type of interaction between faults and the rate at which faults reactivate not only control the long-term tectonic evolution of an area, but also influence seismic hazard, as earthquake recurrence intervals tend to decrease as fault slip rate increases. Furthermore, short-term interaction may generate larger and/or multiple earthquakes.
The Central Apennines Fault System (CAFS) is an interactive active fault system, extending along the central Apennines in a north-south direction for a length of ca. 100 km and ca. 50 km of width. From 1997 to 2016, the entire fault system was activated along its length, thus providing the unique opportunity to verify the seismic hazard estimated by geological and paleoseismological studies. A meaningful comparison may now be carried out considering the seismological data provided, in particular, by the 2009-L’Aquila (Mw=6.3) and the 2016-Amatrice-Visso-Norcia (Mw max=6.5) earthquakes.
Based on high-resolution seismological data, together with the geological surveys carried out prior and after the recent seismic sequences, the objectives of the proposed research is to better understand the interaction processes between active faults (long-term) and earthquakes (short-term) within an active fault system and their control on the seismic cycle of faults, with implications for time-dependent seismic hazard evaluations.
