A section of an active fault that has produced earthquakes in the past but is now quiet and is believed that the fault segment is capable of producing earthquake on some other basis is known as:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Seismic Gap.
A section of an active fault that has produced earthquakes in the past but is currently quiet, yet believed to be capable of generating a future earthquake, is known as a Seismic Gap. This concept is based on the idea that stress continues to build up in that quiet segment over time. Since neighboring segments may have already released stress through earthquakes, the 'gap' becomes a likely site for a future event. Scientists use seismic gap theory to identify potential locations of future earthquakes, as these areas may be overdue for seismic activity due to the absence of recent tremors.
