The earthquake, or seismic tremor, is defined as any vibration in the Earth's crust that originates from its interior. When the vibration is relatively intense, the earthquake becomes perceptible to our senses. When very weak, its recording is done through special devices called seismographs.
The image above depicts the occurrence of an earthquake in Peru. This occurrence can be classified based on the division of earthquakes into two moments: one inside the crust, where the earthquake originated, and another on the surface, the orthogonal projection of the event.
The names used to classify these two moments of an earthquake are, respectively, inside and on the surface:
a) Astenosphere and Hypocenter.
b) Hypocenter and Epicenter.
c) Plutonism and Epicenter.
d) Hypocenter and Convection.
e) Orogenesis and Epeirogenesis.
