TB-4

gr

Testbed, Partners:
TB-4 – Patras and Aegio, Greece – NOA, UPat (YET, GMP, BUW, UPat, NOR)
Area:
125 km2
Affected population:
260,000
General building stock inventory:
Available
Existing infrastructure:
Ports of Aegion and Patras, schools, high-priority build.
Key stakeholders:
Municipality of Aegion; Arsakeia Schools of Patras; Regional Unit of Archaia; Municipalities of Patras, Kalavrita, and Dorida, respectively, Port of Patras, Rio-AntiRio Bridge.
Existing Sensor networks:
National Seismic Broadband and Strong Motion Network (operated by NOA, University of Patras, University of Athens).
TB-setting and seismic hazard:
The Gulf of Corinth is characterized by some of the highest seismic activity in Europe. It covers the third, in terms of population, city in Greece (Patras), with important large infrastructure facilities, a large main port, variety of geological conditions through the cities, a fault spanning the city (Agia Triada Fault), and many public buildings, schools and heritage monuments. Additionally, the Rio–Antirrio Bridge crosses the Gulf of Corinth near Patras and is one of the world’s longest multi-span cable-stayed bridges and longest of the fully suspended type. The town of Aegion will also be included, famous for the topographic plateau across the main fault (latest major earthquake in June 15, 1995) and the two towns of Kalavryta and Lidorikion.
During TURNkey:
44 TURNkey multisensor units (40 accelerometric sensors and 4 GNSS sensors) will be distributed for the optimization of the network for EEW and RRE: free-field (6) in Patras, (12) in Aegion, (7) in Kalavryta and (5) in Lidorikion, respectively, in addition to 10 accelereometric and 5 GNSS sensors for structural monitoring systems in important buildings. The new Aegion port facilities will be monitored, and a model school in Patras (Arsakeia Schools), already included in the monitoring array of Patras and operated by NOA in real time, provides a link to the novelty of school and citizen seismology.
