Background
History & Context
What Changed
- ▶
BEFORE: Tectonic stress was continuously accumulating without recent major release along shallow fault lines near the Assam-Bhutan border. NOW: The magnitude 5.8 event released a portion of this localized tectonic strain, temporarily altering the stress dynamics on adjacent fault segments.
- ▶
BEFORE: Disaster management and infrastructure guidelines in Udalguri relied primarily on theoretical high-risk Zone V models. NOW: The shallow earthquake served as a real-world stress test, highlighting the immediate practical gaps in structural resilience and public panic management.
- ▶
BEFORE: Recent micro-seismic monitoring in the Brahmaputra valley lacked fresh large-scale shallow rupture data. NOW: The 5 km deep epicenter provided the National Center for Seismology with high-resolution data on shallow crustal deformation in the region.

Q1
Correct Statement(s)Which of the following statements is/are correct regarding seismic activity in Northeast India? 1. The entire Northeast region of India falls under Seismic Zone V primarily due to the active collision boundaries of the Indian Plate. 2. Shallow-focus earthquakes generally cause less surface damage than deep-focus earthquakes of the exact same magnitude.
