The pictures of the deadly landslide in Washington State have raised questions about potential landslides in Hawaii.
University of Hawaii Geologist Steve Martel remembers one close in size behind Makaha Valley Towers 1996.
"It ran three stories up the back and there were tens of thousands of tons of rock," he said.
Martel points to dangers, big and small, every year:
-- The massive boulders coming down in Hawaii Kai in 2011
-- A boulder falling in Lanikai in 2007
-- A landslide on the North Shore in 2007 when Kamehameha Highway was shut down, and costing tens of millions of dollars in repairs.
-- The deadly 1999 Sacred Falls landslide that killed eight people and injured scores of others
"I thought Sacred Falls was going to cause some things to happen," Martel said.
"We don't have that kind of money right now," said William Aila, director of the Department of Land and Natural Resources.
In the past 10 years, the DLNR has completed 14 rockfall remediation projects.
Ten more are in the works or on the agency's wish list.
The Department of Transportation lists dozens of similar, too, as does the county.
But Aila said not only is money tight, combinations of private-public land make many situations complicated.
Lanikai is one such place.
"It's a combination of property owners, of how steep the walls of the mountains are, and now you have development. The data are available and the techniques are available," Aila said.
Martel said a big problem is that the state's topographical maps are painfully out dated. There is also no comprehensive hazard survey showing where things have happened, and the state is missing out on technology available now: using lasers to accurately map the ground, or radar to map a surface and how it changes.
"We still have to deal with the present issue, building near mountainsides, near sand dunes, these are all issues we're going to have to deal with," Aila said.
As for that situation in Lanikai, discussions are underway.
Aila said he expects to get word back from landowners on what they want to do in the next month or two.
He said right now, the department is working with county officials around the state to see what more can be done to address the threat of landslides.
City crews are planning to conduct a rockslide hazard inspections and mitigation work on Prospect Street and surrounding areas in Makiki. That work will happen weekdays from 8:30 a.m. to 3:30 p.m.
The project will continue through the end of the year.
