The 2016 Italian seismic hazard model

The Italian reference seismic hazard model was released in 2004, but it has been adopted for the definition of seismic zones in 2006 and for building code only in 2009. At the beginning of 2015 the Seismic Hazard Center (CPS) of INGV was commissioned to coordinate the national scientific community with the aim of elaborating a new reference seismic hazard model, mainly finalized to the update of seismic code. The CPS designed a roadmap to release within 2 years a significantly renewed model, with regard both to the updated input elements and to the strategies to follow, in order to obtain a shared and largely accepted PSHA. The main requirements of the model were discussed in meetings with the experts on earthquake engineering. A public call was opened according to a transparent procedure; we received 24 proposals from many national institutions. The activities were organized in 6 tasks: project coordination, input data, seismicity models, ground motion prediction equations, computation and rendering, validation. In the first phase, the working groups of each task worked separately; in the second phase of the project they collaborated to release a final model. During the project, many scientific aspects were carefully considered, as in many other seismic hazard projects: the use of a declustered catalogue versus a non declustered one, the adoption of the logic-tree approach instead of an ensemble modeling, the definition of objective strategies to assign the weight to each single model, and so on.PublishedSantiago Chile5T.

Planning and managing a seismic emergency: The INGV drill of November 26th, 2015 carried out in the framework of the activity line T5 "Seismic surveillance and post-earthquake operational procedures" | Pianificazione e gestione di un'emergenza sismica: Esercitazione INGV del 26 novembre 2015 effettuata nell'ambito della Linea di Attività T5 "Sorveglianza sismica e operatività post terremoto"

Nella Struttura Terremoti dell’INGV la Linea di Attività T5 “Sorveglianza sismica ed operatività postterremoto” si occupa delle attività di sviluppo di strumenti e procedure per la valutazione in tempo reale degli effetti di terremoti e tsunami e della gestione delle emergenze sismiche. Uno dei suoi obiettivi del 2015 era la formalizzazione dei protocolli di intervento di Gruppi d’Emergenza, avvenuta per Emergeo, Emersito, IES, QUEST e Sismiko con Decreto del Presidente nel luglio 2015. Altro obiettivo era l’elaborazione di un Protocollo di Ente per la gestione delle emergenze sismiche. La bozza preparata nel 2015 prevede l’importante novità dell’Unità di Crisi, mai formalizzata in precedenza. Attraverso questo Protocollo di Ente si auspica di migliorare la risposta logistico-operativa dell’INGV durante l’emergenza, di avere una più rapida conoscenza del fenomeno in corso e di realizzare un’efficace comunicazione verso Protezione Civile, media e pubblico. Per verificare il tutto è stata organizzata un’esercitazione in cui è stato simulato un terremoto di magnitudo 6.4 nel basso Lazio. Si sono così sperimentate l’efficacia del flusso azioni/informazioni durante un’emergenza, il funzionamento dell’Unità di Crisi, la funzionalità dei protocolli dei Gruppi d’Emergenza, l’efficienza delle attività in sede per gli aspetti tecnico-logistici, il flusso di comunicazione interno e le comunicazioni istituzionali esterne (queste ultime simulate). In questo articolo sono descritte le fasi di organizzazione ed attuazione dell’esercitazione. Inoltre, durante il suo svolgimento, la valutazione dell’efficacia dell’organizzazione e delle attività svolte dai gruppi coinvolti è stata affidata ad alcuni osservatori e qui è allegata l’elaborazione dei commenti riportati. Abbiamo fatto infine una sintesi dei risultati positivi e delle criticità emerse dall’esercitazione, attività così importante a nostro avviso da considerarne indispensabile la ripetizione con cadenza quanto meno annuale.Published1SR.

The development of a cloud-GIS platform for the management and sharing of geographic data during the central Italy seismic sequence

For several years, the Istituto Nazionale di Geofisica e Vulcanologia (INGV, National Institute of Geophysics and Volcanology) uses ArcGIS Online (www.arcgis.com), to share information about the real-time seismicity in Italy with other geographical data, geological and seismological, through the development of different WebGIS applications with various customized functionalities. During the earthquake emergency in Central Italy in August 2016,  WebGIS applications have been widely used. They derive from a common platform developed a few months earlier by the LABGIS of INGV-Irpinia. This platform has enabled the management and updating of the seismic data of the sequence in real time and their integration with the leading INGV databases seismological and seismotectonic and those of other Institutes. Moreover, these applications have permission to manage and share information and even data from the activities of the INGV Emergency Groups , such as the location and characteristics of seismic and  accelerometric temporary stations installed by the teams of SISMIKO and EMERSITO and the geological observations from the EMERGEO Group

Geothermal favourability mapping by advanced geospatial overlay analysis: Tuscany case study (Italy)

The geothermal resource exploration generally requires a combined analysis of various geo-information datasets. In this framework the geospatial analysis as the weighted overlay, performed under GIS (Geographic Information Systems) environment, represent a strong tool to solve problems such as the site selection. This technique is applied on not homogeneous input data to perform an integrated analysis and producing favourability maps. This work is based on the development of a new weighted overlay scheme, that combines favourable geological factors, which allow the identification of hydrothermal geothermal resources, and geological hazards (seismicity and volcanism), which can potentially limit the exploitation of a geothermal resource. The technique was tested on Tuscany Region (Italy), where two geothermal fields, Larderello-Travale/Radicondoli and Monte Amiata, are in operation. Results show that the most promising areas mostly coincide with the exploited geothermal fields. Moreover, new areas with a high geothermal favourability are identified. Low-cost and rapid resource evaluation approaches like this could play a key role during the early stages of a geothermal exploration plan. Moreover, this methodology could be extensively used in other geothermal areas not only by the scientific community but also by stakeholders, as first concrete tool to explore a potential resource suitable for exploitation.Published1377-13871TR.

The role of the INGVterremoti blog in information management during the earthquake sequence in Central Italy

In this paper, we describes the role of the INGVterremoti blog in information management during the first part of the earthquake sequence in Central Italy (August 24-September 30). In the last four years, we have been working on the INGVterremoti blog in order to provide quick updates on the ongoing seismic activity in Italy and in-depth scientific information. These include articles on specific historical earthquakes, seismic hazard, geological interpretations, source models from different types of data, effects at the surface, and so on. We have delivered information in quasi-real-time also about all the recent magnitude M≥4.0 earthquakes in Italy, as well as on the strongest events that occurred in the Mediterranean and in the world. During the 2016, central Italy earthquake sequence, the INGVterremoti blog has continuously released information with three types of posts: i) updates on the ongoing seismic activity; ii) reports on the activities carried out by the INGV teams in the field and by other working groups; iii) in-depth scientific articles describing some specific analysis and results. All the blog posts have been shared automatically and in real time on the other social media of the INGVterremoti platform, also to counter the bad information, and to fight rumors. These include Facebook, Twitter and the INGVterremoti App on IOS and Android. As well, both the main INGV home page (www.ingv.it) and the INGV earthquake portal (http://terremoti.ingv.it) have published the contents of the blog on dedicated pages that were fed automatically. The work done day by day on the INGVterremoti blog has been coordinated with the INGV Press Office that has written several press releases based on the contents of the blog. Since August 24th, 53 articles were published on the blog, and they have had more than 1.9 million views and 1 million visitors. The peak in the number of views, which was more than 800,000 in a single day, was registered on August 24, 2016, following the M 6.0 earthquake.Published4TM. Web e SocialJCR Journa
