Which of the following is considered as small earthquakes in underground caves and mines which are caused by the seismic waves produced by the eruption of rock on the surface?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Collapse earthquake.
Collapse earthquakes are small tremors that usually occur in underground caves, tunnels, and mines due to the collapse or sudden failure of rock strata. These quakes are triggered by seismic waves generated from surface-level rock eruptions or stress imbalances, and they are typically localized and less intense than tectonic earthquakes.
