Resum
Seismic wave attenuation in the central region of the Colombian Andes is studied using coda waves. Most of the events used occurred in the region on the occasion of the Armenia 25 January 1999 earthquake. The estimation of the decay rate of coda amplitudes (called coda Q-1 or Qc-1) is performed by means of the single isotropic scattering method of Sato [1977]. The attenuation parameters Qi-1 (intrinsic absorption), Qs-1 (scattering loss), and Qt-1 (total attenuation) are also estimated using the...
