Earthquake Engineering and
Seismology
Coordinator: Mário Santos Lopes
OBJECTIVES
The activities of the Group concern mainly the assessment and reduction of seismic risk, comprising 3 main areas: Seismology,
Earthquake Engineering and Structural Dynamics, and Rehabilitation and Conservation of the Built Heritage.
SEISMOLOGY
1a-Permanent scatterer SAR interferometry
(project Terrafirma): detection of slow
moving landslides and subsidence due
to soil compaction, tunneling or other
engineering works
1b-Probabilistic seismic hazard analysis

Risk of Urban Areas: Applications to
Azores
2b-Seismic behaviour of large reinforced
concrete underground structures in soft
soils
2c-Seismic vulnerability and mitigation of
seismic risk of lifelines
