Figure 5From: Feasibility of acoustic monitoring of strength drop precursory to earthquake occurrenceThe coefficients of transmission |T| and reflection |R| as a function of Σ ≡ (ω c /ω) . Their derivatives with respect to lnΣ, d|T|/d[ ln(ω c /ω)] and d|R|/d[ ln(ω c /ω)], are also shown.Back to article page
