Abstract:

Seismic noise is considered a nuisance to most seismological applications, obscuring meaningful signal and hampering observations. Recent advances in seismic imaging techniques, however, proved that noise is in fact an excellent resource that, not only can provide better resolution for imaging, but can reduce the amount of numerical artifacts in the final images. In this project we propose to use seismic noise to our advantage to transform every single seismic station in Eastern Europe into a virtual source and apply state-of-the art seismic imaging techniques, using data from broadband seismic stations in Eastern Europe to construct the highest resolution 3D seismic images of the lithosphere in the Carpathian-Panonian Region. This is an excellent natural laboratory to study fundamental geological processes such as the evolution of extensional basins, collisional orogens and back-arc volcanism, oceanic subduction, or anomalous earthquake-generating slab break-off. Our results will provide fundamental insights into the geological processes that shaped the Carpathian-Pannonian region, and will provide essential ground motion parameters, useful for civil engineering applications and seismic hazard and risk assessment in socio-economic developing countries of Eastern Europe.

Abstract:

The territory of Romania is characterized by moderate to high seismicity. Notably, the Vrancea zone is known for producing relatively large intermediate-depth earthquakes that pose a high risk for the capital Bucharest and other Romanian cities. Other regions, like Galati, have also experienced recently shallow significant seismic activity that impacted the Galati city and neighboring areas. Here we propose to build a comprehensive analysis and forecasting system for Romanian's seismicity, based on state-of-the-art forecasting models that are currently in use in seismic countries like US, Japan, Italy and Greece. We are planning to use advanced statistical and machine-learning tools to quantify the spatial and temporal features of Romanian seismicity that can be used for short (days to weeks) and medium (several months to one year) earthquake forecasts. The scientific results of the project will be published in international journals and on a dedicated website that finally aims to present real time forecasting information.

Platforma virtuala de colectare si analiza interactiva a datelor geofizice multidisciplinare Call name: P 2 - SP 2.1 - Proiect experimental - demonstrativ

Abstract:

The project was conceived as an answer to users' questions and demands, and their needs have led us to put the basis of the proposal. The final result of the project will be a functional integrated geophysical platform, that will offer public access to information related to: the temporal correlation between global, regional and national seismicity, catalogues, interactive maps and videos; the macroseismic field and maps of all moderate and large Romanian recent and future crustal and subcrustal earthquakes; and the behavior of the geomagnetic field recorded in the last twenty years at stations inside and outside Vrancea seismogenic zone, represented as temporal diagrams with a length decided by the user, and correlated with seismicity and magnetic storms. The platform will also collect, through questionnaires, macroseismic info after an earthquake, offering in return real time answers with the seismic intensity and related explanations and also users’ information on abnormal behavior of animal, clouds, air or water temperature, unexplained atmospheric electricity, or gas emissions that might be assimilated as earthquakes precursors, and an automat alert will be issued to a technician, when the answers number will exceed a normal daily average, for manual processing. This service is necessary for the worried citizens, local authorities, decision makers and emergency situation departments, to be aware of the real situation of seismic or geomagnetic activity. The platform will aggregate a series of institutional data products and data collected from external agencies. The platform architecture will be modular, based on microservices responsible for data synchronization and the generation of products from which the user will create selections based on available data parameters. Behind each service there will be researches that will create tools for seismic and magnetic activity patterns recognition and predictive models for recognizing anomalies will be generated.

Complex system for the prevention of explosions and fires at individual gas installations after earthquakes Call name: P 2 - SP 2.1 - Proiect de transfer la operatorul economic

Abstract:

The project proposes to develop and implement a complex pilot / prototype system for the prevention of devastating explosions and fires caused by natural gas installations damaged by major earthquakes which it will validate under relevant operating conditions. It is the result of the technological transfer from the National Institute for Earth Physics has researches and achievements in this field to an SME that wants to extend its service offer by implementing this application under real conditions to protect the objectives supplied with natural gas. The innovative character of this project is based on a patent application a 2017 00744 / 27.09.2017, “Complex equipment for seismic warning of industrial objectives with local decision and confirmation”, published in OSIM RO-BOPI 3/2019. The structure of the proposed protection system (decision center at NIEP, local confirmation for avoiding alarms that do not cause damage in the protected area and reserve in case of communication interruptions, dispatcher to the SME with final decision role and terminals for gas decoupling) was not more implemented in Romania and no similar achievements are known abroad. The project can be applied to other regions where a dispatcher and a local validation station are created. He intends to make the transition from an existing warning system validated under laboratory conditions (TRL4) to its validation under relevant operating conditions (gas decoupling by seismic events), TRL5. The SME can use the infrastructure that will be created for other applications in the industrial environment (Oltchim combined), dams (Brădișor, Șuici, Vidra) or mining areas (Petroșani, Rovinari) in Oltenia. The results of the project will be disseminated for scientific purposes as well as for informing potential beneficiaries.
