Property loss estimation for wind and earthquake perils.

Area of Science:

• Engineering
• Natural Hazards
• Risk Management

Background:

• Assessing building vulnerability to natural disasters like earthquakes and windstorms is crucial for risk management.
• Existing methodologies may lack global applicability or comprehensive integration of hazard and vulnerability data.

Purpose of the Study:

• To develop a universal loss assessment methodology for earthquake and windstorm perils.
• To integrate hazard estimation with building structural response parameters for accurate loss prediction.

Main Methods:

• Incorporated latest hazard estimation data with parameters defining windstorm and earthquake intensity on structures.
• Evaluated building vulnerability using historical damage data and key structural properties (age, design, construction quality).
• Developed risk-specific mathematical vulnerability functions to predict damage probability and translated damage into monetary loss using cost factors.

Main Results:

• The methodology is applicable worldwide across diverse hazard levels, from low to extreme.
• It enables accurate estimation of losses for potential scenario events tied to defined return periods.
• The approach successfully translates predicted damage into quantifiable financial losses.

Conclusions:

• The developed methodology provides a universal and accurate tool for loss assessment for earthquake and windstorm events.
• It significantly enhances risk assessment and planning capabilities by providing reliable loss predictions.
• The approach is adaptable to various building types and environmental conditions globally.
