🌎 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

🌍📈📍How We Measure Earthquakes

"The Sleeping Scientist"

Imagine you're asleep at night when suddenly your bed starts shaking. You wake up and wonder:
"Was that a small earthquake or a big one?"
You can tell that you felt the shaking, but you don't know exactly how strong the earthquake was.
Scientists have the same problem—except they need accurate measurements. That's why they use a special instrument called a seismograph (or seismometer). It acts like Earth's stethoscope, listening to and recording the vibrations caused by earthquakes.

The recorded lines, called a seismogram, help scientists determine:
✅ How strong the earthquake was
✅ Where it happened
✅ How far the shaking traveled
Just as a thermometer measures temperature, a seismograph measures Earth's shaking.
Did You Know?
A seismograph can detect vibrations too small for people too small for people to feel.
