  • Geographical Location

           

Mainland General Luna is situated at the southern side of Siargao Island, Province of Surigao del Norte. It is bounded on the north by the municipality of Pilar, on the south by the small islands of Daku and La Januza, on the west by the municipality of Dapa and on the east by the Philippine Sea. The municipality is within grid coordinates between 9˚ 47’ to 9˚ 50’ North Latitude and 126˚ 9’ to 146˚ 10’ East Longitude.

           

It is 16 kilometers from the municipality of Dapa and approximately 40 nautical miles from Surigao City.

            The growing tourism center of General Luna has a bewitching 27 kilometers long of sugar-fine white beaches and has a natural cove barrier that protects the place from the onrushing waves of the Pacific. The wide cove can literally accommodate thousands of water skiers and wind surfers. It remains enthralling even during stormy weather.

  • Land Area and Political Subdivisions

           

General Luna the newly discovered surfing paradise occupies a total land area of 5,998 hectares and municipal waters of approximately 90,000 hectares. The town is one of the nine municipalities of Siargao Island and one of the twenty seven municipalities of Surigao del Norte. It is under the 1st Congressional District of the province.

           

The municipality has nineteen barangays with Puroks 1-5 considered as poblacion barangays and fourteen inland, coastal and island  barangays namely: Anajawan, Cabitoonan, Catangnan, Consuelo, Corazon, La Januza, Daku, Libertad, Magsaysay, Malinao, Sta. Cruz, Sta. Fe, Suyangan and Tawintawin

  • Slope

           

Slope is considered as one of the important determinants of land use particularly in agriculture and urban development. This will also serve as control and provide direction on the degree of inclination particularly on surface drainage, soil erosion, susceptibility and rainfall infiltration of the soil. Based on the land use policies, the 0-18 percent slope range are potential for agricultural, industrial and settlement activities, while lands under 18-50 percent slopes are classified to be useful for grazing and production forest. Land categories with more than 50% slope are areas to be protected or protection forest.


Around 3,889 hectares or 65% of the municipal land area are flat and gently sloping with 0-8 percent slopes, indicating its potential for food production and urban development. Almost all of the barangays have flat areas with biggest flat lands from barangays Malinao, Consuelo, Catangnan, Cabitoonan, Anajawan and Tawintawin. Barangay Sta. Cruz has a small flat area while Barangay Magsaysay has a gently sloping area.

  • Soil

           

The soil type of the municipality is basically bolinao clay. This is characterized by the abundance of angular and rounded limestone gravels particular in the surface soils. In the eroded condition limestone boulders and outcrops appear scattered on the surface interfering in the cultivation. Sheet erosion has been serious in the soil.

           

Bolinao clay needs application of phosphate fertilizer like ammophos. Chemical test found this soil to be containing only 3 parts per million of readily available phosphorous which is very much below the normal need of the plants. Farming practices like the addition of organic matter, green manuring, crop rotation with legumes, contour farming and good tillage operation are essential to make the soil produce high yield as well as to conserve it. The soil reaction is slightly acid.

  • Bodies of Water

    

General Luna has wide resources of marine waters with around 92,000 hectares of municipal waters. It has no big rivers though and inland bodies of water except for a number of creeks of brackies water on the mangrove areas found in Malinao, Tawintawin, Magsaysay, Catangnan, Cabitoonan, Libertad and Sta. Cruz.

  • Climate

            The 1996 Climatological Information from PAG-ASA showed that General Luna has a Type II climate characterized by no pronounced dry season but with maximum rain period from November to February. Dry period is from May to September. The municipality experiences an average of 10.25 rainy days per month.

           Around 3,889 hectares or 65% of the municipal land area are flat and gently sloping with 0-8 percent slopes, indicating its potential for food production and urban development. Almost all of the barangays have flat areas with biggest flat lands from barangays Malinao, Consuelo, Catangnan, Cabitoonan, Anajawan and Tawintawin. Barangay Sta. Cruz has a small flat area while Barangay Magsaysay has a gently sloping area.

  • Topography

           

Generally, General Luna has diverse landforms. It has terrain of coastal and hilly plains, mountainous to rolling lands. Poblacion Barangays 1-5 and Barangay Daku have relatively flat areas potential for agriculture and urban development. Barangays Consuelo, Corazon and Magsaysay have mountainous to rolling terrains.The rest of the barangays have a combination of hilly and flat lands. Some mountainous areas being used for infrastructure development are already slightly eroded. The town is very much accessible by land and sea transportation.

  • Hydrogeology

           

General Luna is outside of the seismic zone and thus have a relatively low earthquake occurrence. It has a wide area of marine waters but has no big rivers and inland bodies of freshwater, although a number of creeks can be found in Barangays Magsaysay, Libertad, Cabitoonan, Tawintawin and Catangnan.

           

The area is fringed with extensive rocky reefs serving not only as natural breakwater but also as protection from adverse sea conditions originating from the Pacific Ocean.

           

The surface stream flows are diverted into underground channels since there is no surface drainage system. Another hydrogeological feature of the town is the formation of limestone described as fairly productive aquifers in upper Pliocene-pleistocene reef  brecciated  and karstic limestone. In the coastal areas, there are unconfined waters generally at shallow depths: there are also recent alluvial, locutrine and swamp deposits with impermeable surface overlying the above limestone. In the coastal areas, there are unconfined waters generally at shallow depths; there are also recent alluvial, locustrine and swamp deposits with impermeable surface usually overlying the above formations.
