Abstract
The geology of Lisbon is very diversified, with a predominance of cretaceous rocks (basalt and limestone) in the western zone, while east and south it is covered by progressively thicker Tertiary deposits with diverse lithologies (sands, clays, silts, sandstones and limestones) and different geotechnical properties. Lisbon also contains several narrow long valleys, filled with thin alluvial deposits. A set of new geological profiles was drawn, along the east–west direction, 500 meters spaced. These profiles were based on the existing geological maps and complemented with new information collected from recent geotechnical boreholes. Theoretical modeling, using the Thomson–Haskell 1-D approach, was performed for 314 geological columns chosen from these profiles according to a regular grid 500 meters long. The physical parameters were obtained from specialized literature, seismic experiments and laboratory tests. The results are presented as contour maps for the peak frequencies and for the corresponding amplification factors. These results are compared with the microzonation map obtained by microtremor analysis and with the damage distribution observed in past earthquakes.
