The Institute of Geodynamics (IG), as an institute of the oldest research center in Greece, the National Observatory of Athens, through the seismic and other geodynamic networks that deploys and operates nationwide, has a leading role in the development of seismological research, participating in national or international research projects, aiming to improve the seismic regulations, to disseminate new knowledge, to inform the Authorities and the population. During the recent years, the IG infrastructure (both instrumentation and software) has been significantly improved and various modern methodologies have been adopted for the operational activities of the IG and have greatly improved the services provided to the community. Indicatively are mentioned:
Especially during the last 3 years, within the ASPIDA program, a major development of the infrastructure and improvement of methods and services took place, while a number of external experts of different subjects were involved in the achievement of the objectives of the project. Among the results of the project are the model of active fractures with their position, dimensions, geometry and seismic potential, the application of ShakeMap in a 24/7 operational basis, the creation of modern fault assessment scenarios in the structured environment of large Greek cities, the creation of a catalog of all the monuments and museums in the Greek area, classified according to their archaeological – geological – seismological – tectonic regime, the creation of revised scenarios for the assessment of seismic risk and vulnerability in selected monuments – museums, the development of regulatory guidelines for the protection of the Greek cultural heritage from strong earthquakes and their associated phenomena and the development of a GIS portal.
The GEORISK project, beyond the continuation of equipment upgrading, aims to the further linkage of IG to excellence and international interconnections.
Within Working Package 1 a standardization of methodologies is approached aiming to study and reduce the vulnerability of school buildings against the earthquakes, to improve the seismic behavior of the school community through interdisciplinary activities and to provide useful data from the school community to scientists. This approach links basic and applied research with the daily curriculum and enhances responsible behavior of students, internationally practiced in different disciplines. This reinforces the position of the IG for the partnerships development in this field.
Working Package 2 includes actions that are at the forefront of international interest in assessing tsunami risk and the its mitigation. The scientific scope of the tsunami risk assessment only in recent years has been developed and is included in the agenda of the ongoing ASTARTE research project (FP7-EU) in which the IG is a partner. In addition to the extreme scenario method, the approach includes the application of the independent maximum probability method to incomplete lists. The method will be applied for the first time internationally in the tsunami risk assessment and promises positive results because it has already been successfully applied in assessing seismic risk. The planned tsunami risk assessment and population education fall within the immediate interests of the NEAMTWS / IOC / UNESCO Early Warning System, where the National Tsunami Warning Center is one of the four main pillars together with the respective Centers of France, Italy and Turkey. The same applies to EU agencies, with which the NTWC works closely, such as the Joint Research Center and DG ECHO.
The Working Package 3 approach is a multidimensional methodology, which includes the synthesis of information derived from innovative tools (seismological, geophysical, geodetic, satellite). The synthesis leads to a detailed assessment of the volcanic risk and the development of the latest generation infrastructure, elements that internationally upgrades the IG status.
