The explosion was vast and seemed to go on forever.

A final explosion seems to imply a direct hit has taken place.

Whatever; the explosion seemed to have caught the pursuing police vessels.

Instantly, an explosion seemed to go off inside Data's head.

The explosions seemed to be concentrated near the center of the village now.

He shook the man's hand, but the white explosion of light seemed to fill his head again.

The explosion seemed to go off in his own head.

In any case, the explosion seemed to take all the fight out of the Vodi.

A chilly explosion of white light seemed to fill his head.

The explosion seemed to have happened for no reason at all.
