| Zusammenfassung |
| We examine the possible non-linear behaviour of potentially liquefiable
layers at selected sites located within the expansion area of the town of
Nafplion, East Peloponnese, Greece. Input motion is computed for three
scenario earthquakes, selected on the basis of historical seismicity data,
using a stochastic strong ground motion simulation technique, which takes
into account the finite dimensions of the earthquake sources. Site-specific
ground acceleration synthetics and soil profiles are then used to evaluate
the liquefaction potential at the sites of interest. The activation scenario
of the Iria fault, which is the closest one to Nafplion (M=6.4), is found
to be the most hazardous in terms of liquefaction initiation. In this
scenario almost all the examined sites exhibit liquefaction features at depths of
6–12 m. For scenario earthquakes at two more distant seismic sources
(Epidaurus fault – M6.3; Xylokastro fault – M6.7) strong ground motion
amplification phenomena by the shallow soft soil layer are expected to be
observed. |
