GEOHAZARD MAPPING AND ASSESSMENT PROGRAM
What is Geohazard Mapping and Assessment Program?
The Geohazard Mapping and Assessment Program is a on-going priority program of the DENR, which is being implemented by the Mines and Geosciences Bureau (MGB). Its main objective is to identify areas in the country which are susceptible or vulnerable to various geologic hazards, or geohazards. The program also seeks to provide information to various stakeholders in order to lessen or mitigate the impact of these events.
What are the components of the program?
The program comprises three major activities, namely, rapid assessment survey to generate geohazard maps that will indicate which areas are prone to natural dangers like landslides, flooding and ground subsidence; printing and reproduction of maps, manuals and information materials for public dissemination; and conduct of seminars and workshops for local government officials and public school teachers to increase their awareness and preparedness on various natural hazards, as well as teach them on the proper use of the geohazard maps.
What are geohazards?
Geohazards are naturally occurring geological phenomena that pose danger to people’s lives, properties, infrastructure and communities. These include landslides, flooding and land subsidence. However, in some cases, geohazards can also be induced by human activities.
Geohazards cannot be totally prevented but their impact on people and the environment may be lessened or mitigated.
What have been accomplished so far by the program?
1. Identified the Top 10 provinces highly susceptible to landslides, to wit:
d. La Union
e. Southern Leyte
g. Nueva Vizcaya
i. Mt. Province
2. Identified the Top 10 provinces highly susceptible to flooding, to wit:
b. Nueva Ecija
g. Metro Manila
h. North Cotabato
i. Oriental Mindoro
j. Ilocos Norte
3. Completed the geohazard assessment and mapping of all the 1,634 cities and municipalities, with a scale of 1:50,000.
4. Distributed a total of 75,000 map sheets to all local government units down to the barangay level, with corresponding training and capability-building to interpret the maps.
5. Started the preparation of more detailed geohazard maps in 2011, with scale of 1:10,000, initially targeting 218 municipalities.
