Course description

 

Περιγραφή

The assessment of seismic risk is fundamental for civil protection and insurance of buildings, states and private entities. The course is targeted to students with a civil engineering background and it builds strong understanding of technical seismology, seismic hazard, probability and risk, using hands-on practical sessions to develop a working experience with leading hazard assessment software. After a successful completion, the student should be able to 

a) Build a simple seismic source model

b) Assess the seismic hazard for a site or region

c) Perform classical probabilistic seismic hazard analysis

d) Estimate the risk in terms of losses or casualties for a region or a portfolio of buildings

Mέθοδοι αξιολόγησης

Grading is based on the final exam (50%) and the mandatory semester project (50%). The latter involves the seismic hazard and risk assessment of a small town in Greece via OpenQuake. Presentation of the semester project takes place after the final exam, and it is a requirement for all students.
