AN ACT 
PROVIDING FOR THE ISSUANCE OF A LIST OF LOW-LYING AREAS OF THE 
PHILIPPINE TERRITORY VULNERABLE TO RISING SEA LEVELS AS A RESULT 
OF CLIMATE CHANGE, AND AREAS AT HIGH RISK FOR NATURAL DISASTERS, 
MANDATING THE DEPARTMENT OF ENVIRONMENT AND NATURAL 
RESOURCES, DEPARTMENT OF SCIENCE AND TECHNOLOGY, CLIMATE 
CHANGE COMMISSION AND OTHER CONCERNED GOVERNMENT AGENCIES 
FOR ITS REGULAR UPDATING AND APPROPRIATING FUNDS THEREFOR AND 
FOR OTHER PURPOSES 
This proposed measure seeks the creation of a national hazard map as a major step 
towards risk management. The location of our country makes us vulnerable to a 
variety of natural disasters from earthquakes to strong typhoons. There is also the 
increased vulnerability brought by climate change, increasing sea levels and 
fluctuating temperatures. 
The creation of a national hazard map shall convey a composite picture of the natural 
hazards of varying magnitude, frequency, and area of effect. This has several 
implications in emergency preparedness planning to avoid damages or to reduce 
losses. It will enable us to better prepare for natural disasters by identifying the 
possibilities of occurrence of disasters to specified locations. It will also be 
instrumental in developing evacuation routes that can be easily disseminated and 
understood by all. 
In view of the foregoing, the approval of this bill is urgently sought.

bordering sea levels, exposed to volcanic eruption and lying on earthquake faults, 
with the criteria for evacuation and illustration of recommended evacuation sites and 
routes.
