• The focus is the point on the Earth's surface directly above the epicenter.

• The focus and epicenter are two terms that refer to the same point in an earthquake.

• The focus is the point where two tectonic plates meet, while the epicenter is the area surrounding the fault line.

• The focus is the point within the Earth where the earthquake originates, while the epicenter is the point on the surface directly above it.

Which of the following statements best defines an active fault?

• A fault that has not moved in thousands of years.

• A fault that is located in an inactive seismic zone.

• A fault that has moved recently but is no longer active.

• A fault that is currently moving and capable of producing earthquakes.

How is earthquake intensity different from magnitude? 

• Intensity is measured on the Richter scale, while magnitude is measured on the Mercalli scale. 

• Intensity measures the amount of energy released, while magnitude measures the shaking felt at the epicenter. 

• Intensity is a subjective measure based on observed effects, while magnitude is a quantitative measure of seismic energy release.

• Intensity measures the damage caused by an earthquake, while magnitude measures the depth of the earthquake's focus
