The Trans Adriatic Pipeline (TAP) 765-km onshore pipeline route crosses an area (in Greece and Albania) which is characterized by medium to high seismicity, a demanding morphological relief, and the occurrence of variable and complex geological formations, with diverse features and characteristics. This area also includes geohazards related to earthquakes for which an efficient monitoring and mitigation approach is necessary. For this reason, a new Seismic Hazard Monitoring & Earthquake Impact Assessment system has been developed and integrated with the standard Onshore Pipeline Geohazard Monitoring and Surveillance practices of TAP, to facilitate the handling and mitigation of residual risks due to permanent ground displacement (PGD) effects resulting from earthquake related phenomena (e.g., fault rupture and liquefaction). This system (TAP Virtual Seismic Monitoring System, TAP-VSMS) is based on existing and new seismic data networks, as well as adapted tools, including:

1) A reliable real-time seismic data (seismic waveform) acquisition system, assembling data from all (weak and strong-motion) seismological stations along the main TAP pipeline onshore segment. This hybrid network allows not only the reliable assessment of earthquake locations and their source characteristics (e.g., event location, and magnitude), but also the improved control on seismic motions from strong events. Moreover, a customized notification system (employing SMS, e-mail, etc.) has been integrated in the TAP-VSMS

2) Preliminary assessments of the spatial distribution of dynamic seismic motions along the TAP Right of Way (RoW), using both direct observations (from seismic waveforms), as well as modelling/simulation tools, through a customized ShakeMap module. For this customization, an appropriate inventory of geological, geophysical and geotechnical information was employed to provide an updated Vs₃₀ map along TAP and improve the accuracy of seismic motion near-real-time assessment. Moreover, appropriate regional GMPE and seismotectonic information has been also integrated to further improve the overall system reliability.
