I immediately put the Green Lantern ring on. I focus and create a giant hand and I pull the bus out of the way of the falling rubble. Once I put the bus down next to me I create a protective bubble around myself and the bus. Then I extend it upwards to try and stabilize the buildings falling apart around me. Once the quake passes and the buildings stop swaying, I slowly dissolve the bubble making sure that the buildings are okay on their own.
I use the the ring to open the broken door of the bus. I would then leave quickly while everyone was trying to figure out what happened, so that I wouldn’t be noticed.
