Cost concerns delay safer building codes despite Himalayan threats

चर्चा में क्यों

The Bureau of Indian Standards (BIS) withdrew revised earthquake risk assessment guidelines for the Himalayan region and Northeast India due to concerns over infrastructure project costs.

पृष्ठभूमि

Government-commissioned studies over a decade indicate that current risk assessments underestimate potential earthquake damage. The studies suggest Peak Ground Acceleration (PGA) values in high-risk zones should be doubled or tripled compared to existing estimates.

• स्थानHimalayan region and Northeastern India: Identified as high-risk earthquake zones requiring updated risk assessments.

मेन्स के लिए

Q. Discuss the conflict between scientific risk assessment and economic feasibility in infrastructure development in ecologically sensitive zones like the Himalayas.

उत्तर के आयाम

• Economic-Safety Trade-off: Balancing the high cost of seismic-resistant construction with the necessity of disaster-resilient infrastructure.
• Regulatory Bottleneck: Delay in standardizing PGA values due to concerns over public spending and private construction costs.
• Scientific Accuracy Gap: Underestimation of seismic risk in current building codes despite a decade of government-commissioned research.
