| Where is the Epicenter? | The Epicenter is located directly above the Focus (origin). |
| What is the S-P interval? | The S-P interval is the time between the Primary and Secondary Wave. |
| True or False: The Richter Scale measures the Damage in Roman Numerals. | False: the Mercalli Scale measures the damage in Roman Numerals. |
