  1. Spiking Deconvolution In order to compress seismic signal in time and whiten the spectrum. Advantages: shows embedded signal in noise Disadvantages: heightens noise

  2. Convolutional model

  3. Steps in Spiking Deconvolution • Calculate autocorrelation function (ACF) • Estimate second crossing of ACF in s • Conduct inverse filtering using ACF

  4. Significant arrivals in SP 2Calama, Chile(181207_1) • Refractions (mainly) and reflections
