Question

which did you include in your answer? the intensity increases by a factor of 10. the richter scale uses a logarithm with base 10. for example, an earthquake with magnitude 2 is 10² times more intense than a standard earthquake, while an earthquake with magnitude 3 is 10³ times more intense than a standard earthquake, and 10³ = 10² × 10.

Explanation:

The Richter scale measures earthquake intensity logarithmically with base - 10. Each increase of 1 in magnitude corresponds to a 10 - fold increase in intensity. The examples illustrate how magnitudes relate to intensity compared to a standard earthquake.

Answer:

The intensity increases by a factor of 10.
The Richter scale uses a logarithm with base 10.
For example, an earthquake with magnitude 2 is 10² times more intense than a standard earthquake, while an earthquake with magnitude 3 is 10³ times more intense than a standard earthquake, and 10³ = 10²×10.
