-
B.
Mercalli
chosen
Mercalli is an Italian surname most notably associated with Giuseppe Mercalli, the volcanologist who developed the Mercalli intensity scale for measuring earthquake effects.
-
C.
Japan Meteorological Agency seismic intensity scale
The Japan Meteorological Agency seismic intensity scale is a Japan-specific system that measures and classifies the degree of ground shaking and its effects at specific locations during an earthquake.
-
D.
Modified Mercalli intensity scale
The Modified Mercalli intensity scale is a seismic scale that qualitatively measures the observed effects and damage of an earthquake on people, structures, and the Earth's surface.
-
E.
moment magnitude scale
The moment magnitude scale is a modern logarithmic measure of earthquake size that estimates the total energy released, providing more accurate and consistent results than older magnitude scales for large events.
- F. None of above.
