Rashi, on Ps 96:4

“His lightnings have shone forth to the world: the earth saw and trembled.”

“His lightnings His brilliant lights, an expression of (Ezek. 21:15): “It is polished that it may glitter (ברק).” and quaked “Surely there will be a great earthquake on that day in the land of Israel. And at My presence, the fishes of the sea...will quake.” [The word] וַתָּחֵל is an expression of (above 48: 7): “pangs (חיל) like [those of] a woman in confinement.””
