Homeowners in Aiea have been shaken after a huge boulder crashed into a house and hurt two people. Now neighbors on Holoai Street are wondering what they’ll do to prevent it from happening again. There is a hole in the side of the mountain with some exposed soil and a few roots from plants. That’s where the boulder had been. Once it started rolling down you can follow the trail all the way down the hillside. The four foot tall grass is lying down showing the boulders path. There are even some other separate boulders that appear to have come loose and stopped.
