Which of the following is an effect of an earthquake?

An earthquake produces a variety of effects due to the sudden release of energy in the Earth's crust. Shifting tectonic plates, which is the underlying cause of earthquakes, can lead to various geological phenomena. When these plates move, they can trigger the ground shaking that characterizes an earthquake.

Additionally, one significant consequence of underwater earthquakes is the generation of tidal waves, commonly referred to as tsunamis. These massive waves can travel across oceans and cause extensive destruction in coastal areas.

Moreover, the strong shaking from an earthquake can destabilize soil and rock on slopes, leading to landslides. This is particularly common in areas with steep terrain or loose soil, where the shaking can be enough to dislodge these materials and cause them to flow downwards.

In summary, the correct answer encompasses the broad range of possible outcomes from an earthquake, all of which can occur as a direct or indirect result of the seismic activity.
