Target entity: Modified Mercalli intensity scale Context triple: [1986 San Salvador earthquake, intensityScale, Modified Mercalli intensity scale]
-
A.
Modified Mercalli intensity scale
chosen
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.
-
B.
Richter magnitude scale
The Richter magnitude scale is a logarithmic scale used to quantify the amount of seismic energy released by an earthquake based on instrumental measurements.
-
C.
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.
-
D.
Mercalli
Mercalli is an Italian surname most notably associated with Giuseppe Mercalli, the volcanologist who developed the Mercalli intensity scale for measuring earthquake effects.
-
E.
surface-wave magnitude scale
The surface-wave magnitude scale is a seismic measurement system that estimates earthquake size using the amplitude of long-period surface waves recorded on seismograms.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
