The Potential for Decoupling Explosions in Fractured Hard Rock: Examples from Kazakhstan Historical Data and a New Field Study

Lead PI: Dr. Won-Young Kim

Unit Affiliation: Seismology, Geology & Tectonophysics, Lamont-Doherty Earth Observatory (LDEO)

North America
Project Type: Research

DESCRIPTION: The project has five parts: 1) Instrument deployment and site characterization plan; 2) Deployment of seismographic stations in the northeastern US and southern Canada to collect data from eight test explosions; 3) Data analyses to determine if secondary explosions have smaller amplitudes due to fracturing consisting of spectral amplitude ratios and root mean square analyses of historical data from Dengelen Mt.; 4) a continuation of 3; and 5) examine the spectral characteristics of the explosion sources in the high-frequency range.
