Translation: An enormous crack in the ice forces to evict an Antartic Base.

We have here two verbs. The first one is "obliga". Its infinitive form is "obligar" (to force, to oblige). The subject is the enormous crack in the ice, therefore the verb present the third person singular (It).

To force / To oblige = Obligar
It forces / It obligues = Obliga

The next verb is "desalojar" (to evict). In this case, the verb is in its infinitive form as in the English version.

To evict = Desalojar.

It forces to evict = Obliga a desalojar.
