A seismic hazard is the probability that earthquake shaking of a certain intensity will occur in a given geographic area, within a given window of time. From that, risks can be assessed and included in mitigation efforts. Let's compare them. https://www.iris.edu/hq/inclass/animation/take_2_hazard_vs_risk | EarthScope Consortium

Modern skyscrapers are no longer just feats of height—they are feats of survival. Thanks to cutting-edge engineering like seismic isolation systems, many high-rise buildings can now withstand powerful earthquakes that would have once brought them down. These systems, placed at the base of structures, absorb and reduce seismic energy before it travels upward, protecting the integrity of the building and the lives inside. In some cases, even rooftop pools help balance sway during tremors, acting a

The risk of a building collapsing during an earthquake depends not only on the earthquake’s strength but also on how its frequency matches the building’s natural frequency. Every structure has a natural frequency at which it naturally vibrates. If the earthquake’s vibrations align with this frequency, a phenomenon called resonance occurs, where the vibrations are amplified, making the building more likely to collapse. Taller buildings are typically more unstable at lower frequencies, while short
