  • An isoseismal line can help identify the earthquake's epicenter.

Examples

  • The isoseismal lines showed that the city center experienced the strongest shaking during the earthquake.

  • Scientists use isoseismal maps to study how an earthquake's intensity varies across a region.

  • After each major quake, researchers carefully draw isoseismal lines to analyze the patterns of ground motion.

  • The isoseismal map showed the areas most affected by the earthquake.

Morphology

isoseismal = seismal (semi-transparent) = iso + seism + al

Formed from the combining form 'iso-' (equal) plus 'seismal' (relating to earthquakes); the composition is logical but relies on technical combining forms unfamiliar to average learners.

Etymology

Isoseismal comes from the parts iso- ('equal') and seism ('shake'), the same root you see in seismic. So an isoseismal line joins places that had the same 'shake' or earthquake strength.
