The aim of the project is to improve:
- methodologies for integrated seismic hazard assessment
- observation tools and modeling of crustal and fault mechanics
WP1: Microseismicity (ENS, IPGP, NKUA)
Instruments:
borehole velocimeters (50-100 m),
sufrace broadband velocimeters.
- space-time variation and focal mechanisms of microseismicity
- refined structures and velocity changes with multiplet studies
- crack-induced shear-wave splitting
- relationship between microseismicity and major faults
- empirical Green's function methods for strong motion prediction
WP2: Reference accelerometric array (NKUA, IPSN, ENS, NTUA, IPGP)
Instruments: surface & borehole (-200m) accelerometers on bedrock
WP3: Soft soil borehole array (AUTH, NKUA, IPSN, IPGP, NTUA)
Instruments: borehole and surface accelerometers, pore pressure sensors (0-60m)
- effects of soft soils on ground motion: non-linear response and liquefaction
WP4: Seismic hazard assessment (NTUA, NKUA)
- engineering assessment of the overall project in terms of seismic input requirements, building code recommendations, and microzoning guidelines.
WP5: Geodesy (NTUA, IPGP)
Instruments: continuous GPS
- continuous and repeated measurements of the strain with GPS and inSAR
- modeling of interseismic and coseismic strains.
WP6: Geophysical transients (IPGP, NKUA)
Instruments: strainmeters, long-base tiltmeter, electric/electromagnetic stations,
- identification of transients, and correlation with geochemical and seismic activity
- modeling coupled processes.
WP7: Geochemical transients (ING, IPGP)
Instruments: geochemical monitoring station
- geochemical spatial survey
- identification of transients, and correlation with geophysical and seismic activity
WP8: Tectonics (ING, IPGP, UPSL, Brunel U., AUTH)
- paleoseismology (trenching on fault, coring in sediments, dating) and morphotectonics
- analysis of long time series of rupture events on the major faults.
