Earthquake Impacts and Resilience

Active learning lets students experience the instability of built environments during earthquakes firsthand, building empathy and understanding that lectures alone cannot. By testing models and role-playing responses, students connect abstract data about wave energy to real-world consequences for communities.

• 45 min · Small Groups

Shake Table Simulation: Urban Impacts

Construct a shake table using a wooden board on rubber bands and place student-built model cities from cardboard and clay. Groups apply horizontal shakes of varying intensity, observe primary and secondary impacts like collapses and 'landslides,' then sketch and discuss damage patterns. Compile class data to identify vulnerable infrastructure.

Analyze the primary and secondary impacts of a major earthquake on urban infrastructure.

Facilitation Tip

During the Shake Table Simulation, walk around with a decibel meter to let students hear the difference between controlled and uncontrolled shaking.

What to look for

Provide students with a scenario: 'A magnitude 7.0 earthquake strikes a coastal city with older, unreinforced masonry buildings and a port.' Ask them to list two primary impacts and two secondary impacts on the city's infrastructure and population. Then, ask them to suggest one engineering solution and one community preparedness measure that could have lessened the damage.

Engineering Challenge: Seismic Towers

Provide spaghetti, marshmallows, and tape for pairs to build 60cm towers following simplified building codes. Test on a manual shake table, measure survival time and height retention, then redesign based on failures. Groups present improvements with sketches.

Compare different building codes and engineering solutions designed to withstand seismic activity.

Facilitation Tip

For the Engineering Challenge, provide a limited supply of materials to encourage creative problem-solving within constraints.

What to look for

Facilitate a class discussion using the prompt: 'Imagine you are advising a city council on how to improve earthquake resilience. Based on our study, what are the top three most important investments the city should make (e.g., retrofitting buildings, developing an early warning system, public education campaigns)? Justify each choice with specific reasons and potential benefits.'

Case Study Rotation: Global Responses

Set up stations for three earthquakes (Newcastle 1989, Christchurch 2011, Tohoku 2011) with maps, articles, and data sheets. Small groups rotate every 10 minutes, noting impacts and resilience measures, then share comparisons in a whole-class debrief.

Justify the importance of early warning systems in reducing earthquake casualties.

Facilitation Tip

During the Case Study Rotation, assign each group a different stakeholder perspective (e.g., engineer, mayor, survivor) to deepen empathy and analysis.

What to look for

Present students with images of different building types or structural components (e.g., a building with base isolators, a building with exposed brick, a modern skyscraper with a reinforced core). Ask students to write down for each image whether it is likely to be more or less earthquake-resistant and why, referencing key vocabulary terms like 'base isolation' or 'unreinforced masonry'.

Early Warning Role-Play: Response Drill

Assign roles like residents, engineers, and officials. Simulate a warning alert; participants practice evacuation, securing objects, and decision-making in 2-minute rounds. Debrief on time saved and casualty reductions using props and timers.

Analyze the primary and secondary impacts of a major earthquake on urban infrastructure.

Facilitation Tip

In the Early Warning Role-Play, use a countdown timer visible to all students to reinforce the urgency of protective actions.

A few notes on teaching this unit

Start with unstructured exploration so students notice earthquake effects before formalizing ideas. Use repeated cycles of prediction, testing, and reflection to build conceptual understanding. Avoid rushing to solutions; let students grapple with failed designs to learn why certain engineering choices matter. Research shows that students retain concepts better when they experience cognitive disequilibrium and then resolve it through guided inquiry.

Look for students to move from identifying earthquake causes to predicting impacts and proposing solutions. Success shows in their ability to explain why some structures fail and others survive, using technical terms during discussions and redesigns.

Watch Out for These Misconceptions

• During the Shake Table Simulation, watch for students who assume earthquakes can happen anywhere with equal likelihood.

  After recording earthquake locations on a world map, ask groups to highlight plate boundaries and compare distributions. Use the map to challenge assumptions by asking why some regions have frequent quakes while others have none.

• During the Engineering Challenge, watch for students who believe all tall buildings survive earthquakes if they are built with strong materials.

  Provide students with examples of both flexible and rigid towers to test. Ask them to observe which structures crack first and why, using the failure patterns to correct assumptions about strength versus flexibility.

• During the Early Warning Role-Play, watch for students who think early warning systems can prevent all earthquake damage.

  After the drill, have students compare casualty counts between scenarios with and without warnings. Use the data to discuss what early warnings can and cannot achieve, focusing on response time versus structural integrity.
