Question

The PGA in a seismic hazard map stands for what?

Option 1: Potential Geological Analysis
Option 2: Potential Ground Acceleration
Option 3: Peak Ground Acceleration
Option 4: Peak Geological Analysis

Answer 1

The correct answer is Option 3: Peak Ground Acceleration.

Step-by-step explanation:

The correct answer is Option 3: Peak Ground Acceleration.

In seismic hazard maps, PGA stands for Peak Ground Acceleration. It measures the maximum acceleration that can occur during an earthquake at a specific location. It is a significant parameter used to assess the potential seismic hazard of an area.

For example, a seismic hazard map may use different colors to indicate different levels of PGA, with areas of high PGA indicating a higher risk of strong ground shaking during an earthquake.
