Earthquake Mechanisms. Brittle Mechanical Model: “stick-slip”. Focal point: 3D point inside the lithosphere where the seismic event occurs. Epicenter: projection of focal point to the map surface . Part 1. Seismic Waves and Interior of the Earth. The behaviour of seismic waves in the different layers of the earth provides the most authentic evidence about the composition and structure of the earth. The different types of waves, generated during the occurrence of an earthquake, are generally divided into three broad categories: . travels as seismic waves in all directions through the. Earth’s layers, reflecting and refracting at each. interface. These waves are of two types - . body waves. and . surface waves; the latter are restricted to near the. . EGU 2020. Ilaria Barone.
