Isoseismals are contour lines drawn on a map connecting points of equal seismic intensity. These lines help visualize how ground shaking intensity varies from the epicenter outward.
In this illustration:
The epicenter marks the surface point directly above the earthquake’s focus.
Isoseismal lines form concentric patterns around the epicenter.
Intensity values (like X, IX, VIII...) show how shaking reduces with distance from the epicenter.
📘 Why It Matters:
Helps in Damage Assessment:
Planners and engineers can prioritize response zones.
Essential for Seismic Zoning:
Used in hazard maps to design earthquake-resistant infrastructure.
Visualizes Earthquake Impact:
Gives a real-world understanding of how shaking spreads.
