Answers

Answered by GPT-4o mini
To determine earthquake risk, the most relevant option among those listed is **strain in rocks near faults**.

Strain in rocks can provide valuable information about how much stress is building up along fault lines, which is a critical factor in predicting potential earthquakes. Changes in the color of rocks, hydrogen gas emissions, and the height of ocean waves are not commonly used as reliable indicators for assessing earthquake risk.
