Translated title:
Seismic hazard assessment using the stochastic method of ground motion simulation
Summary:
In the present master thesis, the various characteristics of strong ground
motion that are attributed to a variety of earthquake scenarios from different
areas are calculated. More specifically, calculations of synthetic
accelerograms are performed, using the stochastic method of ground motion
simulation for finite sources (Motazedian & Atkinson, 2005). We first applied
the above methodology in the area of central Greece. The unknown parameters for
the inversion are estimated by comparing the synthetic accelerogram that was
calculated for a real earthquake which occurred in Amfiklia area (MW=5.4) with
the real one that was recorded in Aidipsos area. These parameters are then used
to calculate the synthetic acceleration from earthquake scenarios attributed to
the Atalanti fault. A second application of this methodology is performed in
the region of Sparta. Parametrization is performed as in the previous case,
using the earthquake that occurred at Kalamata in 1986 (MW=6). Synthetic
acceleration is then calculated for earthquake scenarios related to the Sparta
fault. The final application is done for the area of Cephalonia. For this case
the unknown parameters are calibrated using an earthquake that occurred at
26/1/2014, MW=6. Simulation is then performed for a second strong earthquake
that occurred in the same area (3/2/2014, MW=5.9). An assessment of the above
methodology is made by comparing the synthetic accelerogram with the real one
of the second event.
