Dear Colleagues,
This year the IAGA-IASPEI Joint Scientific Meeting will take place in the beautiful city of Lisbon, 31/Aug-5/Sept, 2025 (https://iaga-iaspei-2025.org ), with an exciting program that includes scientific sessions, early career schools, and social events.
Abtract submission is now open and the deadline is quickly approaching - 12/March/2025 (https://iaga-iaspei-2025.org/abstract-submission/ ).
Please consider submitting an abstract to our session:
“S14 The 1755 Great Lisbon Earthquake, 270 years later: Earthquake and Tsunami Hazard & Risk in Portugal and the western central Atlantic”
Conveners: Susana Custódio (Portugal), Luis Matias (Portugal), Marta Neres (Portugal), Rachid Omira (Portugal), Josep Batlló (Spain), Vitor Silva (Portugal)
The great Lisbon earthquake & tsunami of 1 November 1755 remains as one of the most significant events in earthquake and tsunami science. With an estimated magnitude of 8.5-8.7, the earthquake devastated Portugal, caused a tsunami widely observed across the Atlantic basin, and sparked the scientific minds of the epoch, causing an inflamed debate on the causes of the earthquake and ensuing tsunami. This event is considered by many as marking the birth of modern Seismology, considering the detailed and systematic questionnaire on the effects of the earthquake, as well as the rational organization of the relief & recovery efforts.
Given the lack of scientific instrumentation at the time, 270 years later several outstanding questions remain with no consensual answers, namely which fault or sets of faults generated the earthquake, what was its magnitude, what were the contributions of the ground motion, fire and tsunami to the observed destruction, etc… Over past years, many studies and lively discussions on this topic highlighted the difficulty in explaining the observations with a simple model, rather pointing to an earthquake & tsunami with some degree of complexity. In addition, these studies also unveiled a multitude of active faults in the southwest Iberia and Atlantic margins of Portugal, and their mainland counterparts, which together pose a significant risk to Portugal and the western central Atlantic.
In this session we welcome presentations from a broad range of domains that contribute to an improved understanding of earthquake and tsunami risk in Portugal and the western central Atlantic, namely: New analysis of historical datasets; Earthquake modeling, monitoring & warning; Earth structure, down from mantle dynamics up to the oceanic sediments; Tectonics & geodynamics, including the quantification of driving forces and deformation models; Tsunami modeling, monitoring, forecast & warning; and Hazard assessment & risk mitigation. We encourage insights from and for new data acquisition, novel technologies, new data processing techniques including ML, AI, and big data, and critically the integration of different datasets.
