D. The point on Earth's surface directly above where a quake starts.
Part B: Seismic Safety Planner
Imagine you are a safety engineer designing a checklist for a classroom. Explain the exact drill steps.
1. Explain the "Drop, Cover, and Hold On" drill. Why is each step important?
2. Describe one engineering strategy cities use to make buildings earthquake-proof.
Part C: Geological Reflection
Historical Connection:
Why do geologists consider Pompeii to be one of the most important scientific discoveries for studying ancient Rome?

Duration: Hurricanes last for days; tornadoes usually last for minutes.
Warning: Hurricanes are tracked days ahead; tornadoes form with very short notice.

HISTORICAL DATA
Wind History
Hurricane Spotlight
Hurricane Katrina, 2005
In August 2005, Category 3 Hurricane Katrina struck the Gulf Coast. The massive storm surge breached the protective levees in New Orleans, flooding 80% of the city.
Impact: Rewrote federal emergency guidelines and improved flood wall engineering.
Tornado Spotlight
Tri-State Tornado, 1925
On March 18, 1925, the deadliest tornado in US history carved a 219-mile path across Missouri, Illinois, and Indiana. It traveled at speeds of 60-70 mph.
Impact: Highlighted the critical need for advanced storm detection radar and sirens.

SAFETY PREPARATION
Emergency Plans
Hurricane Preparation
Plan Evacuation: Know your local safe evacuation route.
Board Windows: Install storm shutters or plywood.
Supplies: Store 3 days of fresh water, food, and batteries.
Always obey official evacuation orders!
Tornado Preparation
Get Low: Go to a basement or storm cellar.
Get Inside: Find an interior room away from windows.
Protect Head: Cover with blankets, a mattress, or a helmet.
Mobile homes are not safe shelters!

STORM DISCUSSION
Review
Let's Discuss as Storm Detectives!
1
Explain why warm ocean water (above 80°F) acts like "fuel" for a developing hurricane. What happens when it hits land?
2
Why are tornado warnings much more urgent and harder to prepare for than hurricane warnings?
3
In the 1925 Tri-State Tornado, there were no advanced radar systems. How would modern radar systems have helped save lives?

Doppler radar
Storm Tracker Tip: Evacuation vs. Sheltering Hurricanes allow days of warning, making evacuation the safest option. Tornadoes offer minutes, requiring immediate shelter in low, interior rooms.

Part A: Hurricane vs. Tornado Matrix
Compare and contrast the two major wind storms using evidence from the article on Page 1. Fill in each grid box with clear geological details.

Part B: Emergency Action Plan
Imagine you live in Tornado Alley, and your local weather channel just issued a Tornado Warning.
1. Where is the absolute safest room in your house or school to seek shelter from a tornado? Why?
2. List three critical items you should bring with you into the shelter room and explain their survival purpose.
Part C: Historical Reflection
Katrina & Levee Engineering:
Based on the article on Page 1, explain why Hurricane Katrina was not just a wind disaster, but also an engineering disaster. What failed and what was the consequence?

3. Safety Map (15 min) Draw or map out the safest zones in your own school building. Practice walking to that zone quickly and quietly.
Unit 1: Earth Unleashed (Teacher Guide) Page 1 of 1
Impact: Led to the world's longest system of levees and massive river control structures.

ECOLOGICAL ENGINEERING
Mitigation
Fighting Wildfires
Defensible Space: Clearing grass and dry branches within 30-100 feet of a home to starve fire of fuel.
Prescribed Burns: Purposely burning small areas of brush under safe, controlled weather to thin out fuel layers.
Fighting Floods
Levees & Spillways: Earthen walls along rivers that prevent water overflowing, routing excess to empty plains.
Permeable Pavement: Special concrete that lets rainwater pass directly through into the ground.
Earth Unleashed Unit Slide 5 of 7
SAFETY PREPARATION
Action Protocols
Wildfire Safety
Ready, Set, Go!: Maintain a packed survival bag and follow official evacuation routes.
Close Openings: Shut windows and doors to prevent floating embers from flying inside.
Never stay behind when a mandatory evacuation is called!
Flood Safety
Turn Around, Don't Drown: Never walk or drive through flowing water. Just six inches can sweep a person away!
Seek High Ground: Head upstairs or up hills immediately during a flash flood.
Avoid touching floodwaters due to chemical contamination!

ECO-DISCUSSION
Review
Let's Discuss as Environmental Experts!
1
Explain why dry wood, strong wind, and heat from the atmosphere are a recipe for "The Fire Triangle." How do they work together?
2
Why are cities made of concrete and pavement more prone to flash flooding than grassy forests? Explain using soil saturation.
3
How does clearing "defensible space" around a building help shield it from an approaching wildfire?

Part A: The Combustion Equation
Based on your reading on Page 1, analyze how fire suppression works. Select which side of the Fire Triangle is being removed in each action.
1. Firefighters drop thousands of gallons of red fire retardant chemicals directly onto forest tree branches.
Fuel (Leaves) Oxygen (Air) Heat (Cools)
2. Emergency crews throw sandbags and dirt blankets over small brush campfires.
Fuel (Leaves) Oxygen (Smothers) Heat (Cools)
Part B: Defensible Space Plan
Imagine you are a forester advising a mountain homeowner on how to defend their house from approaching wildfires.
1. Explain why maintaining a 30-foot circle of bare ground protects a house from fire lines.
2. Besides removing branches, what is another way the homeowner should prepare their roof and gutters? Why?
Part C: Ecological Reflection
Urban Saturation Paradox:
Why does a heavy storm produce flash floods in a city much quicker than in a thick natural forest? Use the "Sponge" analogy from Page 1.
