Notes about the Seismic Hazard Assessment of Region VI(Active Faults, Liquefaction and Tsunami)

1. Attached indicative maps were used for the assessment. These maps were generated using 1:250,000 topographic maps and other satellite imageries.

2. These indicative maps can be utilized to identify approximate locations of areas at risk to earthquake hazards, land-use planning and disaster management.

3. Detailed study (1:50,000 to 1:10,000 scale mapping) to determine the trace of these active faults and other related earthquake hazards is needed before any major infrastructure development is initiated in the area.

4. Municipal boundaries were based on GIS data from National Statistics Office (2002).
