Earthquake Basics (ELI5 Style)
What Is Magnitude?
Think of magnitude like a volume knob for earthquakes:
- It measures how much energy was released at the source
- It replaced the old Richter scale (same idea, better math)
How Strong Is a 2.1?
| Magnitude Range | What It Feels Like | Damage? |
|---|---|---|
| Below 2.5 | Usually not felt by people | No |
| 2.5 – 5.4 | Often felt, but rarely causes damage | Rarely |
| 5.5+ | Strong shaking, can cause damage | Yes |

Where Do Earthquakes Happen?
They can happen anywhere, but they’re most common in:
- Alaska
- California
- Hawaii
- Oregon
- Puerto Rico
- Washington
By the Numbers: Earthquakes Worldwide
| Stat | Number |
|---|---|
| Detectable quakes per year | 500,000 |
| Felt by people | 100,000 |
| Cause damage | ~100 |
That means most quakes are too small to notice, and very few cause harm.
What Earthquakes Can Cause
Even if the shaking stops, danger can continue:
- Fires (from broken gas lines)
- Tsunamis (near oceans)
- Landslides or avalanches (in mountains)
What to DURING an Earthquake: Step-by-Step
Golden Rule: Drop, Cover, and Hold On!
No Matter Where You Are:
- DROP to your hands and knees
- COVER your head and neck with your arms
- HOLD ON to something sturdy (like a table leg)
- STAY PUT until shaking stops
Situation-Specific Tips
| Where You Are | What to Do |
|---|---|
| In a car | 1. Pull over safely 2. Stop 3. Set parking brake 4. Stay inside until shaking stops |
| In bed | 1. Roll face-down 2. Cover head with pillow 3. Stay there |
| Outdoors | 1. Move away from buildings, trees, power lines 2. Drop, Cover, Hold On 3. Don’t go inside |
| Indoors | 1. Stay inside — don’t run out! 2. Stay away from doorways (they’re not stronger) 3. Crawl under a sturdy table 4. If no table: go to an interior wall, away from windows |
| Using wheelchair/walker | 1. Lock wheels 2. Stay seated 3. Cover head/neck with arms |
After the Shaking Stops: Stay Alert!
Important Callout:
Dangers don’t end when the shaking stops.
- Damaged buildings might collapse
- Leaking gas or water lines
- Downed power lines
- Aftershocks — smaller quakes that follow the main one
Be ready to Drop, Cover, and Hold On again if you feel an aftershock!

FAQ
1. Is a 2.1 magnitude earthquake dangerous?
Nope! It’s very small. Most people don’t even notice it. Quakes under 2.5 are rarely felt and almost never cause damage.
2. Why are there so many small quakes in California?
California sits on top of the San Andreas Fault system — where two giant tectonic plates slide past each other. Lots of stress = lots of little quakes.
3. Should I stand in a doorway during a quake?
No! That’s an old myth. Doorways aren’t stronger in modern homes. Get under a sturdy table instead.
4. What’s an aftershock?
A smaller earthquake that follows the main one. They can happen minutes, hours, or even days later — and they can still knock things down.
5. How can I prepare for a bigger quake?
- Secure heavy furniture to walls
- Keep a go-bag with water, food, flashlight, meds
- Practice Drop, Cover, Hold On with your family
- Know how to turn off gas/water
