EQE 681 - Earthquake Risk Assessment
COURSE NO AND TITLE : EQE 681 - Earthquake Risk Assessment
- General Terminology: Definitions of seismic hazard, vulnerability, fragility, risk, loss.
- Regional scale and urban scale risk assessments
2 Hazard Assessment and Characterisation of Strong Ground Motion
2.1 Probabilistic hazard assessment
Time-independent and –dependent
2.2 Deterministic hazard assessment
2.3 Ground motion intensity measures (IMs)
Macro seismic intensity: MMI, EMS-98 etc.
Instrumental intensity: PGA, PGV, Sa, Sd etc.
Different IMs for different physical elements at risk
2.4 Ground Motion Prediction Equations (GMPEs)
Inter- and intra-earthquake variability
2.5 Ground Shaking Maps
Spatial distribution of ground shaking intensity
3 Elements at Risk
3.1 Physical elements
Buildings, lifeline networks (electricity, water and waste-water, gas and oil, telecommunication), transportation infrastructures (bridges, road network), essential facilities (schools, hospitals, etc), industrial elements and historical heritage
3.2 Social elements
Demographic data and associated socio-economic indicators for vulnerability assessment
3.3 Taxonomy definitions
Classification of physical elements at risk on the basis of pre-defined typologies
3.4 Compilation of inventories
Ground surveys, remote sensing techniques, census and owner/operator data, and crowd sourcing.
4 Physical and Socio-Economic Risk Assessment
- Correlation of ground motion parameters with damage to built environment
4.1 Direct approach
Seismological method, given epicentre and magnitude of the event, estimation of casualties
4.2 Regional scale
Intensity-based engineering method, estimation of damages and casualties
4.3 Urban scale
Analytical method, spectral capacity-based vulnerability assessment, estimation of damage, casualties and direct economic losses
5 Fully Probabilistic Risk Assessment
- Probability of loss exceedance
