How does Nelson DeMille use imagery in By the Rivers of Babylon?

Imagery:

"Only her mouth smiled, Laskov noticed. Her dark eyes remained expressionless. That full, rich mouth had become quite accomplished at showing the full range of human emotion, while the eyes only stared."

"She noticed that new almond blossoms had come out during the night and the hills were smudged with pink and white clouds. The rocky foothills were softly green and carpeted with brilliant red anemones, cream-colored lupins, and yellow daisies. The yearly miracle of rebirth had returned, and along with the wildflowers brought into bloom by the Hamseen, peace was breaking out in the Holy Land. Or so it seemed."

"The silence of the place screamed in his ears as if he were hearing the ghostly crashing of Babylonian chariots, the fleeing enemy, and the shouts of her victorious armies."
