Resumo(s)
In spite of the significant number of studies focused on the 1755 earthquake and tsunami,
there are still many unknowns regarding this event in Lisbon, Portugal. Thus, in this research the
authors compiled historical documents, including some that had never been analyzed, complemented with a field survey and tsunami numerical modeling at the historical civil parish of Santo
Estevão, Lisbon. It was possible to identify 13 buildings, including three religious buildings and
five palaces. Furthermore, the new data showed that contradicting the general idea, the earthquake
caused significant damage to the selected territory because the number of households decreased by
52%. The number of residents decreased to about 51%, and in 1756, 1041 residents were still living
in 297 temporary shelters. There were more than 44 dead and 1122 residents were unaccounted for.
The fire did not hit the area, and the tsunami numerical model results were validated by the historical accounts and cartography, which indicate that the coastal area of the studied area was not
significantly inundated by the tsunami. The consultation of historical documents that had never
been analyzed by contemporary researchers provides a breakthrough in the knowledge of the
event since it allowed a very detailed analysis of the disaster impact.
