Mercalli Scale
Measures
Richter Scale
The effects caused by
earthquake
The energy released by the
earthquake
Measuring
Observation
Tool
Quantified from
observation of effect on
Calculation earth’s surface, human,
objects and man-made
structures
Scale
I (not felt) to XII (total
destruction)
Consistency
Varies depending on
distance from epicenter
Seismograph
Base-10 logarithmic scale
obtained by calculating
logarithm of the amplitude
of waves.
From 2.0 to 10.0+ (never
recorded). A 3.0 earthquake
is 10 times stronger than a
2.0 earthquake.
Varies at different distances
from the epicenter, but one
value is given for the
earthquake as a whole.
34. At which location would earthquakes be least likely to occur?
a. 1
b. 2
c. 3
