Test your understanding of earthquake focal mechanisms
← Back to Focal Mechanism ExplorerThis quiz will test your ability to identify fault types from beachball diagrams, match parameters to mechanisms, and understand focal mechanism concepts.
Each session has 12 randomized questions across 5 question types:
1. Visual ID — Identify the fault type from a beachball
2. Parameter Match — Determine fault type from strike/dip/rake
3. Reverse ID — Pick the correct beachball for a fault type
4. Conceptual — Theory questions about focal mechanisms
5. Interactive — Adjust sliders to match a target beachball
