- Other than boundaries of crustal plates earthquake may occur
within areas with
(A) frequent civil activities
(B) frequent explosive activities
(C) frequent deforestation activities
(D) frequent volcanic activities​

Answer 1

(D) frequent volcanic activities​

Earthquakes are normally prompted when rock resistance abruptly interrupts along a fault. This sudden discharge of energy produces the seismic waves that make the earth tremble. When two sections of rock or two servings are rubbing against each other, they attach a little.

Tremors can also occur far from the borders of plates, accompanying faults. Faults are cracks in the earth where segments of a plate (or two plates) are traveling in various directions. Faults are produced by all that bumping and launching the plates do. They are more prevalent near the boundaries of the plates.

Answer 2

within areas with frequent volcanic activities​.

Earthquakes usually occurs when there is a sudden movement in the Earth's crust. It is accompanied by rupture and trembling effect on the surface of Earth.

Most earthquakes occur along the edge of the oceanic and continental plates.  Also, the regions with frequent volcanic eruptions is mostly prone to Earthquakes.
