  How the prepared states and Unruh effect affect
Measurement-Induced-Nonlocality (MIN) is studied. We show that, as the Unruh
temperature increases, the MIN between modes $\mathrm{A}$ and $\mathrm{I}$
decreases but the MIN between modes $\mathrm{A}$ and $\mathrm{II}$ increases.
We prove that the parameters $c_i$ which decide initial prepared states affect
not only the values of the MIN, but also the dynamical behavior of it. By
comparing the MIN with the maximal expectation values of CHSH inequality and
geometric discord between modes $\mathrm{A}$ and $\mathrm{I}$, we also find
that the MIN is more general than the quantum nonlocality related to violation
of Bell's inequalities, and its values is always equal or bigger than that of
the geometric discord.
