Concettina Nunziata is Professor of Geophysics at Università degli Studi di Napoli Federico II. Her researches mainly regard the analysis and the interpretation of active and passive seismic signals, and the modelling of seismic ground motion. The main themes are:

1. Multifilter analysis with FTAN method applied on signals generated by active and passive sources. The aim of the analysis is the extraction of the fundamental mode of surface waves.
2. Non linear inversion of the group/phase velocity dispersion curve of the fundamental mode of surface waves. The thicknesses and the shear wave velocities of the structural model are changed in the inversion process.
3. Complete seismograms computation (volume and surface waves) for laterally heterogeneous anelastic structures with the modal summation technique, for the one-dimentional part of the model, and with the finite difference method for the two-dimensional one.
4. Ambient noise analysis both for the seismic site effect (resonance frequency) and for retrieving the Green function between two receivers (noise cross-correlation technique).

PROJECTS

The PETIT-OSA platform, acronym of the PON project 2002-2006 “Piattaforme Evolute di Telecomunicazione e di Information Technology per l’offerta di Servizi al settore Ambiente” was a communication system of research centres for the ambient monitoring and the control, the prevention and the emergency management. The Campania region was chosen as test area. The monitoring regarded the effects of slow deformations on the built areas, the fires and their simulation and control of propagation; the air quality with the pollution level forecast until 72 hours before for the city of Napoli; the geochemical monitoring of the volcanic activity was finalized to the determination of parameters to use as volcanic eruptions indicators; The seismic zonation monitoring of the urban area of Napoli regarded the seismic level connected to earthquakes and human activity vibrations; the soil and water pollution monitoring; the landslides risk monitoring.

The main results are riported in a volume published by ARACNE, C. Nunziata editor
