Tectonic risk and resilience

Fictional earthquake planning case: in District R, 240 of 800 inspected buildings lack adequate reinforcement; District S has 90 of 300. Both are exposed to the same modelled shaking intensity. R has more residents and slower emergency access. These are invented inspection data, not real earthquake losses. Distinguish earthquake magnitude from shaking intensity.

R has more residents and slower emergency access. These are invented inspection data, not real earthquake losses. Calculate each district's percentage of inadequately reinforced buildings. What does the comparison show?

R has more residents and slower emergency access. These are invented inspection data, not real earthquake losses. Explain why R may have greater disaster losses despite equal shaking and reinforcement percentages.

R has more residents and slower emergency access. These are invented inspection data, not real earthquake losses. Evaluate whether a limited budget should prioritise retrofit or emergency access in R.
