In two sentences, what is the main objective of designing earthquake-resistant structures?
The primary objective of designing earthquake-resistant structures is to protect human lives by preventing catastrophic structural failure during seismic events. These buildings are specifically engineered to withstand the intense ground motion and lateral forces caused by severe shaking. Ultimately, this approach ensures that structures maintain enough stability for occupants to safely evacuate and essential facilities to remain functional.

Can Earthquakes be anticipated?
No. but scientists identify areas likely to experience earthquakes by studying fault lines, monitoring ground movements, analyzing historical seismic activity, and using advanced geophysical tools to assess long-term risk.

A) Urbanization
B) Seismic Retrofitting
C) Geotechnical Excavation
D) Fault-line Mapping
B) Seismic Retrofitting

RECITE RISK FORMULA.
Risk = Hazard (The Quake) x Exposure (People & Assets) x Vulnerability (Weak Buildings)
a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
EARTHQUAKES
Thick, reinforced concrete vertical walls that run through the core of a building to prevent it from tilting or twisting during shaking.
