2.1.4. Main scientific and engineering outcomes
The following items present a short summary of major scientific and engineering
achievements for many topics in earthquake engineering, engineering seismology and
seismology, taking advantage of a multidisciplinary field and laboratory experiment
using the largest infrastructure in Europe (for further details, please see Raptakis et al.,
