We propose the entropic measurement-induced nonlocality (MIN) as the maximal increment of von Neumann entropy induced by the locally non-disturbing measurement, and study its behaviors in both the independent and common structured reservoirs. We present schemes for preserving the MIN, and show that for certain initial states the MIN, including the quantum correlations, can even be enhanced by the common reservoir. Additionally, we also show that the different measures of MIN may give different qualitative characterizations of nonlocal properties, i.e., it is rather measure dependent than state dependent.
► Features of the entropic measurement-induced nonlocality (MIN).
► Comparison of MIN with other quantum correlation measures.
► Enhancement of MIN and other quantum correlations by common reservoir.
► Relativity of the geometric and entropic MIN measures.
