Tectonic plates found in the ocean are called oceanic plates while those found in continents are continental plates. With the movement of these tectonic plates, energy is formed and can be released once these plates meet in the so-called fault line. The intensity of this released energy will also determine that of the earthquake. One can feel the earth’s shaking once energy is released from the earth’s crust. On a few occasions, earthquakes have foreshocks. Foreshocks are a smaller version of earthquakes that occur in the same area as the bigger earthquakes that ensues. Up until now, scientists have not been able to tell whether an earthquake is a foreshock until the real earthquake occurs. The real or larger earthquake is known as the mainshock.
