Which of the following statements is/are correct with reference to the lineament?
A. A lineament is a linear feature in a landscape dictated by an underlying geological structure such as a fault.
B. Sonitpur district of Assam lies within a tectonically complex triangular area bounded by the east-west trending Atherkhet Fault.
C. The northeast is demarcated as Seismic Zone V, which indicates a zone with high vulnerability.
D. All of these
Explanation:
An unfamiliar lineament is among four factors behind frequent earthquakes in northern Assam’s Sonitpur area. A lineament is a linear feature in a landscape dictated by an underlying geological structure such as a fault. According to the Geological Survey of India (GSI), Sonitpur district lies within a tectonically complex triangular area bounded by the east-west trending Atherkhet Fault, the northwest-southeast trending Kopili Fault and a north-south trending lineament. The northeast is demarcated as Seismic Zone V, which indicates a zone with high vulnerability. The Indian plate is moving northeast toward the Eurasian plate in the Himalayan region, their oblique collision and release of stress and strain accumulated in the local tectonic or fault environments lead to earthquakes.
