PPT-Internal Structure of Earth based on Seismic Evidence

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 .

February 1977, the Department of Seismology from the Romanian Geophysical and Geological Institute (GGI) together with the Laboratory of Geodynamics of the Romanian Academy formed the Centre of the Earth Physics (CEP). In 1994, after a governmental decision, CEP was transformed in the National Institute for Earth Physics (NIEP). NIEP is coordinated by the Romanian Ministry of Education, Research, Youth and Sport. .
