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 . 95 NO 4 25 AUGUST 2008 475 For correspondence email piyooshrautelagmailcom Earthquakesafe Koti Banal architecture of Uttarakhand India Piyoosh Rautela and Gi rish Chandra Joshi Disaster Mitigation and Mana gement Centre Department of Disa Douglas Wiens.
