Our main results in this article provide lower bounds for the depth of the first three powers of $I$ in terms of the diameter of $G$. More precisely, we show that $\\depth R/I^t \\geq \\left\\lceil{\\frac{d-4t+5}{3}} \\right\\rceil +p-1$, where $d$ is the diameter of $G$, $p$ is the number of connected components of $G$ and $1 \\leq t \\leq 3$.
