Day 3 - Earthquake-Proof Structures


This is a picture of the Hagia Sophia in Istanbul, Turkey.

This ancient mosque has survived 1,500 years of severe

earthquakes while modern buildings have collapsed

around it. What did the architects of this building know

about earthquake-proofing?


Today's Problem:

You are on a panel of building experts that will advise

the leader of Sumatra about how they can

earthquake-proof their infrastructure. Sumatra

depends on the rich volcanic soils of the land

for survival so they are not willing to move

regardless of the seismic threat. Based on

the results of your experiments with

distribution of weight, variation

of size, variation of height, and variation of

foundation material, you will determine

how architects can make it safer for humans

to live in this dangerous region.



Use these links to do your research today:


How are people building stronger houses in Haiti?


Why are building codes important?


What happens when buildings are not built properly?


How do engineers test buildings for earthquake durability?


Video of testing a earthquake-proof home


Map of Sumatra


Which buildings are the most earthquake-proof?


Compare graphs of building height vs. durability

(you have to click on the building type listed to see the graphs, you should compare the tall buildings to the short buildings)


How can this ancient building survive earthquakes for 1500 years?


The world's largest earthquake-proof building
