  We prove a Second Main Theorem type inequality for any log-smooth projective
pair $(X,D)$ such that $X\setminus D$ supports a complex polarized variation of
Hodge structures. This can be viewed as a Nevanlinna theoretic analogue of the
Arakelov inequalities for variations of Hodge structures due to Deligne, Peters
and Jost-Zuo. As an application, we obtain in this context a criterion of
hyperbolicity that we use to derive a vast generalization of a well-known
hyperbolicity result of Nadel. The first ingredient of our proof is a Second
Main Theorem type inequality for any log-smooth projective pair $(X,D)$ such
that $X\setminus D$ supports a metric whose holomorphic sectional curvature is
bounded from above by a negative constant. The second ingredient of our proof
is an explicit bound on the holomorphic sectional curvature of the
Griffiths-Schmid metric constructed from a variation of Hodge structures. As a
byproduct of our approach, we also establish a Second Main Theorem type
inequality for pairs $(X,D)$ such that $X\setminus D$ is hyperbolically
embedded in $X$.
