Is the Delhi Haridwar ridge, a seismic barrier? A site-specific seismic attenuation study in the Delhi-NCR Region, India

Key Points

• The analysis indicates that the Delhi Haridwar ridge may significantly reduce ground motion during seismic events, enhancing safety.
• Key evidence shows a reduction of seismic waves by 30% in regions near the ridge compared to adjacent areas.
• Observational analysis across various locations in Delhi-NCR assessed seismic attenuation characteristics of the Haridwar ridge.
• Implications support the need for improved urban planning, highlighting the ridge's potential role in mitigating seismic risks.
