The vertical rheological properties of the earth varies a lot. The lithosphere is rigid and divided into a number of tectonic plates. The underlying asthenosphere is quasi-liquid(in geological time) enabling the movement of the upper lithosphere. When the lithosphere is subjected to a large enough stress(from the asthenosphere), it will crack, resulting in diverging(destructive), converging(constructive) or transversing(conservative) tectonic plates. When these plates are displaced with respect to each other, a largeand violent amount of energy is released, resulting in volcanoes, mountains or earthquakes. In this project, a model of the Earth's interior is made using a synthetic wave, called a wavelet by computing a seismogram (a diagram expressing the displacement of the Earth). First, the necessary theory will be explained followed by an implementation of the theory. This will give an estimate ofthe reflectivity of the Earth's interior as well as a modelled seismogram. The results will consequently be discussed, both mathematically and physically. |
