This is in contrast with the seismic magnitude usually reported for an earthquake.Recall – Earthquake “size” described by two measurements: 1. Intensity—a measure of the degree of earthquake shaking at a given locale based on the amount of damage 2. Magnitude estimates the amount of energy released at the source of the earthquake. Measuring the Size of EarthquakesAn earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth 's lithosphere that creates seismic waves.Great earthquakes, such as the 1964 Good Friday earthquake in Alaska, have magnitudes of 8.0 or higher.
