Earthquake Hazards: Primary and Secondary

Active learning works for this topic because students must physically and visually experience how shaking, saturation, and displacement translate into hazard types. Handling materials and analyzing real cases lets them build accurate mental models that static explanations cannot convey.

Activity 01

Case Study Analysis35 min · Small Groups

Model Building: Liquefaction Shake

Provide trays with dry sand, wet sand, and saturated sand layers. Students shake trays at set frequencies using a simple shaker device, observe settling and flow, then measure surface displacement. Groups record variables like water content and shaking intensity, drawing links to real soil conditions.

Differentiate between primary and secondary earthquake hazards.

Facilitation TipDuring Model Building: Liquefaction Shake, ask groups to predict which soil samples will liquefy before the shake, then compare predictions to observations to surface misconceptions immediately.

What to look forProvide students with a brief description of an earthquake scenario. Ask them to identify at least two primary and two secondary hazards that could result, and briefly explain why each is classified as primary or secondary.

Activity 02

Jigsaw50 min · Small Groups

Jigsaw: Hazard Impacts

Assign groups one earthquake case, like Christchurch 2011 or Sumatra 2004, focusing on primary or secondary hazards. Each expert group analyzes data on impacts and mitigation, then jigsaws to teach peers. Conclude with class timeline comparing hazard sequences.

Explain the conditions necessary for liquefaction to occur and its destructive potential.

Facilitation TipWhen running the Case Study Jigsaw, assign each expert group a different hazard type so every student must teach their findings to peers, building accountability.

What to look forPose the question: 'Under what specific geological conditions is a submarine earthquake most likely to generate a destructive tsunami versus causing significant localized ground shaking?' Facilitate a class discussion where students use key vocabulary to explain their reasoning.

Activity 03

Case Study Analysis40 min · Pairs

Simulation Pairs: Tsunami Waves

Pairs use shallow water trays to model seabed uplift by pushing the bottom suddenly, timing wave travel and height changes with depth. Add barriers as coastlines, measure run-up, and graph results. Discuss parallels to real monitoring systems.

Analyze the formation and impact of tsunamis generated by submarine earthquakes.

Facilitation TipFor Simulation Pairs: Tsunami Waves, have pairs alternate roles of operator and recorder so both students process the wave formation and timing data.

What to look forPresent students with images or short video clips depicting different earthquake impacts (e.g., collapsed buildings, flooded coastlines, tilted structures, flowing mud). Ask them to label each as a primary or secondary hazard and provide a one-sentence justification.

Activity 04

Case Study Analysis45 min · Small Groups

Mapping Carousel: Hazard Zones

Stations feature maps of a tectonic region; students identify primary and secondary risk zones, annotating triggers and mitigation. Rotate every 10 minutes, adding peer notes. Whole class synthesizes a composite risk profile.

Differentiate between primary and secondary earthquake hazards.

Facilitation TipDuring Mapping Carousel: Hazard Zones, rotate students through stations every three minutes so they actively compare causes, effects, and data across locations.

What to look forProvide students with a brief description of an earthquake scenario. Ask them to identify at least two primary and two secondary hazards that could result, and briefly explain why each is classified as primary or secondary.

A few notes on teaching this unit

Teach this topic by moving from concrete to abstract: start with hands-on modeling to establish mechanisms, then use case studies to add human and geographic context. Avoid overloading students with lecture; instead, use guided inquiry where students articulate patterns before receiving formal terms. Research shows that tactile experiences combined with collaborative explanation deepen retention and transfer of hazard concepts.

Successful learning looks like students reliably distinguishing primary from secondary hazards, explaining mechanisms like liquefaction or tsunami generation, and using evidence from models and case studies to support their reasoning. They should also transfer this understanding to new earthquake scenarios.


Watch Out for These Misconceptions

  • During Case Study Jigsaw: Hazard Impacts, watch for students assuming secondary hazards are always less destructive because they appear later in news reports. Redirect by having groups compare total affected areas and economic losses from both hazard types in their assigned cases.

  • During Model Building: Liquefaction Shake, watch for students believing liquefaction only occurs near coasts or during massive quakes. Redirect by having groups test multiple soil types with the same moderate shake to see liquefaction in inland sands.

    During Model Building: Liquefaction Shake, have groups test multiple soil types with the same moderate shake to see liquefaction in inland sands, then record their observations on a class chart.

  • During Simulation Pairs: Tsunami Waves, watch for students assuming all submarine quakes produce tsunamis. Redirect by having each pair test both vertical and horizontal fault movements and measure wave height differences.
