1. Introduction
Lisbon was affected by moderate to strong earthquakes along its history, such as the earthquakes of January 26th, 1531, and November 1st, 1755. This last earthquake (M8.5) is considered by many authors as the largest earthquake that stroked Europe in historical times. Its source was located S-SW offshore Portugal, it produced a large tsunami that crossed the entire ocean to the Caribbean and it strongly affected a large area containing the whole country and large regions of Morocco and Spain. Moreover, its effects were also felted in Northern European countries. In this event, the town of Lisbon was severely damaged. Many houses and monuments collapsed and a large part of the population (estimated around 10%) lost their lives (Pereira de Sousa, 1919-1932). Due to its historical seismicity and to its economic and social importance, Lisbon is nowadays considered to have moderate to high seismic risk (e.g. Matias et al., 2005). It is well known that local ground conditions change the characteristics of surface seismic response as its amplitude, duration and frequency content. So, the seismic microzonation is a valuable tool for city planning and for identifying seismic mitigation measures (e.g. Panzera et al., 2018; Alonso-Henar et al., 2018; Hassan et al., 2017; Kolat et al., 2012; Hamzehloo et al., 2007; Bramerini et al., 2015). Seismic microzonation maps were developed for different sites in different countries around the world, as the studies of Jiménez et al. (2000), Topal et al. (2003), Kienzle et al. (2006), Kiliç et al. (2006), Di Giulio et al. (2008), Papadimitriou et al. (2008), Walling and Mohanty (2009), Eker et al. (2012) and Kolat et al. (2012).
