A mass of dirt, debris, and rocks all came crashing down on Diamond Head Road Tuesday afternoon.
Luckily, no one was in harm's way when it all happened, but officials were forced to shut down Diamond Head Road in both directions for hours as they cleared the mess. Nearby resident Craig Patterson, saw the mounds of dry dirt come crashing down.
"Looking back on it I just figured a wall caved in or something, but then it started coming down like an avalanche and all the stuff you see on the bottom started coming in," said Patterson, a Waikiki resident.
Patterson was across the street at Makalei Beach Park when he heard an incredible noise. He says the landslide unfolded before his eyes for a full minute.
"It just started slow motion and then it picked up real quick and then it just ended as fast as it started," said Patterson.
Roughly 50 feet of a retaining wall that wraps around a third of the property on Makalei Place went down. It took trees and telephone wire with it and created truck loads of debris that spilled onto the road. Police shut down both lanes of the street during the work that lasted for four hours.
"I feel we should be okay but there's no guarantee," said John Nigro, road supervisor for the City's Department of Facility Maintenance.
Using a loader and a pair of dump trucks the crew cleared the street and hauled away five truck loads in all. During the clean up, another portion of the brittle wall collapsed causing concern for the city crew whose main focus is on safety. The crew cleared the debris off the street, but left the rest because it's the homeowners responsibility to secure their property.
"Tomorrow morning it would be of essence that he do something right away. It's important because I don't want to see anybody get hurt and neither does anybody else," said Nigro.
Diamond Head Road was reopened at around 9:15 p.m.
Officials say they still don't know what triggered the rockslide, but they were able to clear way most of the mess. It's now up to the home owner to shore up the wall and make sure it's safe. We're told that person is not in the islands at this time, but has been notified.
