APPENDIX 1 - Basin models used for 2D local seismic
response simulations
1) SECTION TYPE 0, BASIN DEPTH 50 m
3) SECTION TYPE 1, BASIN DEPTH 50 m
5) SECTION TYPE 1, BASIN DEPTH 50 m (open from left side)
7) SECTION TYPE 2 BASIN DEPTH 50 m (open from left side)
Shallow basins (section type 1, basin depth 25 m) 10) BASIN WITH 375 m HALF-WIDTH
12) BASIN WITH 2100 m HALF-WIDTH
NOTES
o Polygon in green is the seismic bedrock (light green if is weathered) o Polygon in light rose is the cover material
o Points in red are the control points, in particular: P9 is the centre of the closed basin o Case 9 section half-width is 200 m, and its depth 100 m
