Why is bamboo construction considered an ideal indigenous technique for earthquake resistance in Assam?

The correct answer is - Due to its high strength-to-weight ratio and flexibility. Key Points In Assam and other parts of Northeast India, bamboo is a primary material for traditional 'Ikra' houses. Bamboo possesses a very high strength-to-weight ratio , meaning it is incredibly strong for how light it is. This is crucial during an earthquake because the force exerted on a building is proportional to its mass (Force = Mass x Acceleration). A lighter bamboo structure experiences much lower seismic forces than a heavy concrete or brick building. Furthermore, bamboo is naturally flexible . It can bend and sway during tremors without snapping, allowing the structure to absorb and dissipate seismic energy. This makes it an ideal indigenous construction technique for a region located in the highly active Seismic Zone V. Additional Information Bamboo is often referred to as 'green steel' due to its structural properties and sustainability. Traditional bamboo houses in Assam are often built on stilts to protect against frequent flooding, showing an integrated approach to multiple hazards. Modern engineering is now looking at engineered bamboo to create larger, sustainable, and earthquake-safe urban buildings.
