These verbs mean to destroy completely. Annihilate often implies that the destruction is so severe that nothing is left or salvagable: The cannon blasts annihilated the enemy's fortifications.
Exterminate emphasizes the elimination of that which is considered undesirable, especially by killing: "The land had been rendered treeless, as though a tree were a parasite that needed to be exterminated, its stump uprooted and purged" (Madhusree Mukerjee).
Extinguish is to put an end to something or to make something extinct: The teacher's criticism of my essay extinguished my enthusiasm for the project.
To obliterate is to leave no trace of that which is destroyed: The virus obliterates all data on the hard drive of any computer it infects.
