Question

Which of the following magnitude of an earthquake results in serious damage?

• A. 5.5 to 6
• B. 7.0 to 7.9
• C. 6.1 to 6.9
• D. 5.1 to 5.4

Hint:

Magnitude 7.0+ earthquakes are major and often cause serious damage; preparedness is key.

Answer 1

The Correct Option is B

To determine which magnitude of an earthquake results in serious damage, let's analyze the effects of each range on the Richter scale:

1. 5.1 to 5.4:
These are moderate earthquakes that may cause slight damage to buildings and structures, particularly in vulnerable areas. They are unlikely to cause serious damage.

2. 5.5 to 6.0:
These are moderately strong earthquakes that can cause damage to poorly constructed buildings but generally result in only minor to moderate damage to well-built structures.

3. 6.1 to 6.9:
These are strong earthquakes that can cause significant damage in populated areas, especially if buildings are not earthquake-resistant. Serious damage is possible, but it depends on depth and location.

4. 7.0 to 7.9:
These are major earthquakes that almost always cause serious damage, including the collapse of buildings, infrastructure failure, and potential loss of life. They are capable of widespread destruction.

Final Answer:
The magnitude range that most consistently results in serious damage is 7.0 to 7.9.
