Answer:
The table below shows approximately how many earthquakes occur each year in each magnitude range and what the intensity might be at the epicenter for each magnitude range.
*Magnitude ~Average - modified -upintesity
number mercalli
intensity
0 – 1.9 ~ >1 million — micro – not felt
2.0 – 2.9 ~ >1 million I minor – rarely felt
3.0 – 3.9 ~about 100,000 II – III minor – noticed by a few people
4.0 – 4.9 ~about 10,000 IV – V light – felt by many people, minor damage possible
5.0 – 5.9 ~about 1,000 VI – VII moderate – felt by most people, possible broken plaster and chimneys
6.0 – 6.9 ~about 130 VII – IX strong – damage variable depending on building construction and substrate
7.0 – 7.9 ~about 15 IX – X major – extensive damage, some buildings destroyed
8.0 – 8.9 ~about 1 X – XII great – extensive damage over broad areas, many buildings destroyed
9.0 and above ~< 1 XI – XII great – extensive damage over broad areas, most buildings destroyed.
Magnitude / Intensity Comparison
The following table gives intensities that are typically observed at locations near the epicenter of earthquakes of different magnitudes.
Magnitude Typical Maximum
Modified Mercalli Intensity
1.0 – 3.0 I
3.0 – 3.9. II – III
4.0 – 4.9. IV – V
5.0 – 5.9 VI – VII
6.0 – 6.9 VII – IX
7.0 and higher VIII or higher
