The document is a report from Professor Andrew Malone providing comments on an interim report by the Korean Society of Civil Engineers regarding landslides that occurred in 2011 at Umyeonsan Mountain in South Korea. Some of the key comments include: [1] rainfall intensities at the top of the mountain may have been significantly higher than reported stations and return periods are uncertain; [2] landslide hazard zoning methodology has limitations and may not be reliable enough; and [3] the contribution of landslides from an Air Force base to deaths and damage was not insignificant as reported.
