Ultrasonic characteristics of sediment core near tsunami area of Indonesia

  • Received Date: 2007-11-28
  • Rev Recd Date: 2008-01-29
  • The measurement and principle of ultrasonic measurement of sediment core are int roduced.The core sample neart sunami area of Indonesia in 2004 has been measured.The velocity of vertical profile in sediment was presented through the processing and analyzing of data.The relationship is discussed and given between the velocity and the frequency.Analyzing the influence of the depth,structure and biology content of sediment on the velocity data indicates that structure disturbing and gas mixing of marine sediment by the seaflo or earthquake have much influence on the velo city of sediment.
