Landslide Danger Checklist: Revisiting Cherry Hills Disaster of 1999

In my research on causes of and experiences with landslides in relation to the danger Ma-a Shrine Hills is threatened with, I came across these two articles:

One, a STUDY entitled RECENT TRENDS AND MEASURES FOR SEDIMENT-RELATED DISASTERS IN THE PHILIPPINES by Senior Geologist Guillerma Jayne T. Atienza, Bureau of Design of the Department of Public Works and Highways. This study is technically oriented but brief, readable, and very interesting, particularly the topic on Landslides and Slope Failures because the same factors apply to our own Shrine Hills danger threat. It is a check list of what to look for in our own situation. The photo below of the Cherry Hills Disaster paints a grim picture of what could happen to Ma-a Shrine Hills and the houses below.

Second, an Asian Economic News article about Cherry Hills, entitled "Japanese charged with negligence in housing collapse," conveniently over-looks apparent negligence and inaction by the Rizal, Antipolo LGU in enforcement of HLURB rules and of stopping the development. The LGU seem as much at fault as the Developers themselves, I think. Prompt action by the LGU could have protected the residents in their area of responsibility.

Will the concerned National Agencies and City Officials please prevent another Cherry Hills disaster?
