🌎 Earthquake Awareness Series
Episode 4: Understanding Seismic Waves

Seismic waves can be represented using graphs.
Amplitude = Height of the wave (strength of shaking)
Frequency = Number of waves in a given time
Wave Speed = How fast the wave travels
Graphs are used to compare seismic waves and determine:
✔ Which wave arrives first
✔ Which wave travels fastest
✔ Which wave causes the most damage

📐 Math Connection

📈 Wave Graphs Show:
Amplitude → Strength
Frequency → Number of Waves
Speed → Distance ÷ Time

Episode 3: Why Do Earthquakes Happen?

📐MATH CONNECTION

✅Geometry – Earth's layers form concentric circles
✅ Measurement – Comparing layer thicknesses
✅Coordinates – Locating earthquakes on maps
✅Direction – Plate movement using arrows and vectors
✅ Data Analysis – Studying earthquake patterns
✅Rates – Calculating plate movement over time

🌎Earthquake Awareness Series – Episode1
🌎 Magnitude vs. Intensity: What's the Difference?
Think of an earthquake like a light bulb.
💡 Magnitude = How much power the bulb produces.
Measures the energy released by the earthquake.
There is only one magnitude for each earthquake.
Example: Magnitude 6.5
📍 Intensity = How bright the light appears to you.
Measures how strongly the shaking is felt in a specific place.
Different places can experience different intensities from the same earthquake.
Example: Intensity III in one city, Intensity VI in another.
Simple Rule to Remember
🔵 Magnitude = Size of the earthquake
🔴 Intensity = Strength of shaking felt by people
Example
An earthquake has a Magnitude 7.0.
People near the epicenter may feel Intensity VII (very strong shaking).
People farther away may feel Intensity III (weak shaking).
👉 One earthquake = One magnitude 👉 One earthquake = Many intensities
