Engineering Geological & Geohazard Assessment Report/Geohazard Assessment Report
RAPID GEOHAZARD ASSESSMENT
- Scale of Output map: 1:100,00 to 1:50,000
- Information gathered during the field:
- Notations on possible causes or contributing parameters
- Impacts created such as:
- Number of affected households/properties
- Amount of damage (infrastructure, agriculture, etc)
- Field documentation (i.e. pictures and/or video footages)
- Depth and width of floodwaters
- Breadth of a slide
- Actions taken:
- Immediate information of the concerned local authorities or residents in the area about the possible risk involved
- Prepare technical report that would be immediately release to authorities (e.g. Secretary, Director, Regional Executive Director/Regional Director, NGA/LGU concerned) within appropriate time, and if necessary within 36 hours from the completion of work
RECONNAISSANCE GEOHAZARD ASSESSMENT
- Scale of Output map: 1:50,000
- Information gathered during the field:
- Historical accounts or records of incidence(s)
- Location(s) of previous or historical incidence(s) which is also plotted/pinpointed on the map
- Whenever necessary, sampling of rock /soil or any datable information is made for future analytical or laboratory works.
- All the communities or barangays within the project area are being covered for the purpose.
- Rate of completion depends on the area and number of concerns
- Team consists of:
- Four (4) geologist
- Two (2) geologic aides
- At least 80% of the total # of barangays in three (3) municipalities could be covered in two(2) weeks
(almost the same as rapid geohazard assessment but with some additional data such as)
