Check understanding
- Explain that a seismometer is an instrument that detects and records ground shaking
- Describe earthquake energy as waves that travel outward from where rocks broke
- Interpret a magnitude number as a measure of an earthquake's strength
“If your child heard a news report about a magnitude 6 earthquake, could they explain what a seismometer is, that earthquakes send waves through the ground, and that higher numbers mean stronger quakes?”
