PHYSICAL FEATURES

Geographical Location

Ozamiz City is approximately within the geographical coordinates 123⁰39’50” and 123⁰52’45” east longitude and 08⁰04’05” and 08⁰12’30” north latitude. It is located at the southern part at the province of Misamis Occidental and is nestled at the western side of the entrance of Panguil Bay in Region 10 in Northwestern Mindanao.

It is bounded on the North by the Municipality of Clarin; on the east by Iligan

Bay and Panguil Bay, separating the city from the two (2) geographically proximate cities that are Cagayan de Oro and Iligan; on the south by the city of Tangub and on the west by the Municipality of Don Victoriano. It has a total territorial land area of Sixteen Thousand Four Hundred Seven (16,407) Hectares excluding the contested areas that are not yet resolved.

Political Subdivision and Land Area

The city consists of Fifty One (51) barangays, Twenty Three (23) of which are urban and urbanizable, while twenty eight (28) are rural. Ozamiz City is in the second (2nd) congressional district. It is a third class component city. Topography

Ozamiz City is characterized by its low flat elevation in urban areas rising in gentle slope westward as it approaches the interior. The terrain toward the western boundary bordering the Municipality of Don Victoriano and Tangub City (passing the buffer zones of the delineation of Mt. Malindang Range Natural Park which was proclaimed as national park and watershed reserve by virtue of Republic Act 6266), is particularly rugged and very sparsely settled as hills and rolling lands are among its physical features.

The elevation of Ozamiz City ranges from the flat lowland of the poblacion and its coastal barangays at about 1.9 meters above sea level to 562.55 meters above sea level of the nearest barangay approaching Mt. Malindang, Barangay Gala. Other highly elevated barangays are Guimad, Trigos and Sangay Daku having an elevation of 432.25 meters and 235.43 meters respectively (Table III-1). It is not surprising that the climates in these particular barangays are noted to be cool and chilly, the inviting charms that made them a promising potential for tourist development. Mt. Malindang, the landmark of the city and of the province of Misamis Occidental has the highest elevation of approximately 2,411 meters above sea level. The mountain serves as a protecting wall against typhoons and strong winds.


Slope Ozamiz City’s land area is divided into the following existing land slopes:

A. 0 – 3% - Comprising barangays San Antonio, Gango, Doña Consuelo,

Labo, Carmen Annex, Bacolod, Maningcol, Aguada, Tinago, Catadman, Carangan, Molicay, Baybay San Roque, Baybay Sta. Cruz, Baybay Triunfo, 50th District, Calabayan and Lam-an with a total land area of 7,090 hectares.

B. 3% – 8% - Gently sloping to underlying slope are barangays Malaubang,

Bagakay, Tabid, Dimaluna, Diguan, Labinay, Pulot, Cavinte, Balintawak, Cogon, Mentering, Liposong, Dalapang, Gotokan Diot, Capucao C, Pantaon and Kinuman Sur with a total land area of 2,895 hectares.

C. 8% – 18% - Moderately sloping to slightly rolling are barangays Sangay

Daku, Capucao P, Kinuman Norte, Gala, Guimad, part of Trigos with a total land area of 2,300 hectares.

D. 18% – 30% - Strongly sloping to slightly rolling are barangays Trigos,

Guingona and part of Guimad with a total land area of 1,704 hectares.

E. 30% - 50% - Steep. It comprises an area of 1,550 hectares.

F. 50% and above - Steep to hilly or mountainous. It composes the total forestall area of more or less 868 hectares.

About 60.85% of the city has a slope between 0 – 8% described as generally flat to gently sloping which means that 9,985 hectares (0-3 is 43.21% while 3-8 is 17.64% to a total of 60.85%) which is more than ½ of the land resources is within the developable range. Moderately sloping to slightly rolling (8 – 18%) comprises about 2,300 hectares (14.02%) and the rest are strongly sloping to steep mountains. The remaining area of about 4,122 hectares (25.12%) is in the steep and protection-oriented slope range (18% and above) (Table III-2).

Geology

Geologically, the City of Ozamiz is of volcanic in origin. Indications are shown with the presence of hardened lahar in some barangays within the city particularly in Kinuman Norte and Gala. Pyroclastic rocks as well as its sedimentary sequences are found in barangays along Labo River such as Gala, Kinuman Norte, Capucao P, Capucao C and Pantaon. Soils There are eight types of soil found in the city. These are the beach sand/hydrosoil, bantog clay loam, guimbalaon clay loam, adtuyon clay, adtuyon clay loam, camiguin clay, jasaan clay loam and mountain soils (undifferentiated). The Hydrosol Clay represents the water-logged and marshly areas along the coast fringing mouths of rivers and creeks. Mangrove, nipa palms, api-api, and other water loving plants comprise the vegetation. This area is no value in terms of agricultural plantation but it nonetheless contributes much to the economy of the city.


Some sections are ideal site for fishponds and these are being developed for bangus and prawn culture. The Bantog Clay is found along portion of the coastal areas and extended to a sizable area upland. It is best suited for ricelands and other agricultural purposes. This kind of soil is developed from recent alluvial deposits. The relief is level to nearly level of slopes of 3% or less. The Guimbalaon Clay Loam is developed through the intense weathering of balsatic and andesitic rocks. This soil is from brown to reddish brown and is very well drained externally and internally. Rock outcrops are commonly found and so are ravines and gorges. Its elevation is about 200 to 500 feet above sea level. The native vegetation consists of secondary forest and various species of grass. The physical characteristics of the Guimbalaon Clay Loam, stony phase are similar to those of the proceeding soil type except that its surface layer is stony. Inspite of the presence of stones and gravel on the surface of this kind of soil, this phase is devoted to some raw seasonal crops as well as coconut.

The greater part of the Adtuyon Clay type of soil is covered by second growth forest and grasses particularly the sector lying at the foot of the mountain. The lower slopes are planted to various seasonal and permanent crops. The smoothly sloping areas are extensively planted to coconut.

Camiguin Clay type of soil is derived from volcanic sand, basalt and andesite. The salient characteristic of this series is the abundance of the big boulders and outcrops of basalts and andesites on the surface. The relief ranges from rolling to hilly and mountainous with a maximum elevation of about 1,000 feet above sea level. About 60% of this area is cultivated the major portion of which is devoted to coconut and the remaining to the clean culture crops such as rice and corn.

Jasaan Clay Loam soil series is derived from igneous rocks such as basalt and andesite. This ranges from gently sloping to hilly and mountainous. The elevation reaches to a height of about 3,500 feet. The native vegetation consists of secondary forest and cogon which are found in the upper section and steeper slopes. The lower section as well as the gentle slopes is planted mainly with coconut, upland rice, corn, sugarcane, root crops, banana and fruit trees.

The last soil type, the Mountain Soils (undifferentiated) is sometimes referred to as ‘Forestal Zone’. This miscellaneous land type is in accessible because of rugged terrain, thick forest and lack of trails. It covers the entire Mt. Malindang range. Vegetation is composed of primary and secondary forest and grasses. Mineral Resources There is no detailed data on the presence of either metallic or non-metallic minerals in the city. The aggregate materials found abundant in Ozamiz City are sand and gravel in pebble, cobble and boulder sizes. Quarrying of the non-metallic aggregates are used for road construction, foundation and building works. The aggregates are dominantly boulders of volcanic rocks being basaltic and andessite. They are classified as dirty types, with a high percentage of deleterious matter. Width measures up to 10 to 15 meters.


Along road cuts, large boulders with volcanic rocks were encountered enclosed in highly weathered laterite soil. The unweathered fragments could be crushed to pieces for gravel and weathered matrix, being lots soil and clay, could be used as a good binding materials for an all purpose road.

There is no detailed data on the presence of either metallic.

Climate Under the Corona system climate classification of the country, Ozamiz City belongs to Type IV by virtue of its rainfall pattern or distribution in the area. With this classification, rainfall is more or less evenly distributed throughout the year although the months of February to April are considered drier. There is no incidence of typhoon in the area as majority of Mindanao Island is outside the typhoon belt.

Table 3 Shows the 10-year meteorological data taken from PAGASA station in Dipolog City. It is the nearest station, which is about 70 kilometers from Ozamiz City. This information can best describe the climatic condition in the area. Based on the data, the average monthly temperature ranges from a low of

22.7°C to a high of 32.7°C. Mean monthly temperature is at 27.3°C. The relative

humidity in the area does not vary much. It ranges from 80% to 86%. The skies

over the City are cloudy most of the time. Much clearer skies occur in the months of

March and April. Average wind speed throughout the year is at 1 to 2 meters per

second.

Table 4 and Figure 1 Shows the rainfall pattern taken from the same weather

station. The amount of rainfall is generally influenced by factors such as geomorphic position, topographic setting and wind system prevailing in the area. The northeast monsoon, which generally blows from north to east in the months of October to January, brings a lot of rainfall in the area. The month of November is considered the wettest month with an average monthly rainfall of about 400 mm of rainfall. The highest figure for the past 10 years is about 900 mm. It is also the month that has the highest average rainy days at 22 days. Trade winds take an east to southeast path from the months of February to April. This is the transition period going to southwest monsoon season. The rain gradually weakens at these months. Southwest monsoon, which comes from the southwest and west direction, reaches Mindanao from the month of June to October. Increasing rainfall intensities in the area can be observed. Rainfall is evenly distributed within these months. Average rainy days ranges between 16 to 20 days a month. The area receives an average annual rainfall that ranges from 1,415 mm to 3,758 mm. Average annual rainfall is at 2,312 mm. The total number of rainy days for a year ranges from 149 days to 270 days with an average of 206 days. The city falls under type IV or Intermediate B Type of the Corona System of Classification wherein rainfall is more or less fairly distributed throughout the year. There is no pronounced dry season. The rainiest months are from November to December while the driest months are from February to March. However, periodic


disruption in the climatic set-up can be observed brought about by certain phenomenal abrupt climatic changes like the El Niño and La Niña trends. In terms of moisture content and the amount of rainfall received, the city is divided into two (2) agro-climatic zones. The mountain range and other highland areas (forest areas, Guimad, Gala, Stimson Abordo, Guingona, and Trigos) fall under type A, which is wet, having a rainfall of 2,500 mm and a slight dry season moisture deficit. The lower and coastal areas fall under Type B which is moist with rainfall of 1,500-2,500 mm and moderate dry season moisture deficit (please see Map 4 ) Temperature The mean minimum monthly temperature of 27.7oC is almost uniform throughout the year and does not drop below 26.8oC. However, the temperature in the forested areas especially at the mossy portion (South Peak, Peak 2,026) is observed to be lower than 26.8oC reaching as low as 18.0oC. Relative Humidity The change of humidity in the whole province is observed to be uniform in all areas. The optimum rate of humidity from November to December ranges from 85-86% while during the dry months of March and April, the rate is 79%. Major Wind Streams Cyclonic, northeast monsoon is the most prevalent wind system in the city, occurring from November to February. In the month of April, easterly waves from north to south cause the equal distribution of rainfall. May is the month of transition between trade winds season and the southwest monsoon, which is prevalent from July to September. During this period, precipitation caused by adiabatic cooling of air masses as they move across the mountains of the watershed which produce rainfall distribution. The southwest monsoon reaches the province of Misamis Occidental in June to October and the distribution of rainfall is caused by the vertical situation of shoreline between the Pacific Trade and southwest monsoon.

Frequency of Tropical Cyclones The province of Misamis Occidental is always visited by tropical cyclones but their occurrence is relatively irregular. However, the cyclonic impact (e.g. Damages to properties) is less significant considering that the province is flanked by the mountain ranges at the West Side and the Lanao mountain ranges at the East Side.


Hazard Profile

A. Hydro-metreological hazards

1. Flooding

Flood is the abnormal rising and overflowing of a body of water. It

usually results from high precipitation caused by excessive and continuous downpour brought about by typhoons or monsoon rains. Factors that affect the vulnerability of an area to flooding are surface geology, topography, amount and duration of rainfall, vegetation and land cover.

1.1 Riverine Flooding

The most flood prone areas in Ozamiz City are the flood plains of Labo River. Flooding in these areas have already claimed lives and caused tremendous damage to property including the destruction of agricultural lands and infrastructure. Flooding in these areas occur during heavy precipitation, usually in the months of June to December. Floodwaters usually rise from 1 to 2 meters. Barangays located on the floodplains of Labo River include Barangays Calabayan, Molikay, Carangan, Labo, Embargo, Gango, Gotokan Daku and Banadero.

In 1999, a province-wide flooding event occurred after a typhoon. Purok 1 of Barangay Gango was flooded when Labo River overflowed. Purok 3 of Barangay Labo and Purok 2 of Barangay Lam-an were likewise affected. Purok 2 of Barangay Lam-an was submerged by 0.5m floodwaters. According to residents, floodwaters receded after two days.

Riverine flooding is not only confined to the floodplains of Labo

River. Flooding is also caused by Hinagdong and Pulot rivers and Gango, Tipanoy, Diguan, and Labinay Creeks. Flooding in these rivers and creeks affects Barangays Diguan, Pulot, Tabid, Bongbong, Malaubang and Balintawak.

In 1987, Hinagdong River overflowed and flooded Purok 2 of

Barangay Balintawak. The flood affected crops and livestock.

Flashfloods caused by Tipanoy Creek affects Barangay 50th District, which is the commercial center of Ozamiz City.

During heavy rains, the creek overflows rendering the submarine bridge leading to Sangay Diot impassable to vehicles and people.


In Barangay Bongbong, the Ozamiz City Socialized Housing Project located in Purok 5 is prone to flooding due to its proximity to a meandering creek. Also, the housing project is built on top of stream deposits. During heavy rains when water volume in the creek is large, floodwaters in the creek may cut across plains and seek a shorter route abandoning the curve of the creek and inundating the housing project instead.

1.2 Coastal Flooding

The Ozamiz City Coastal Zone (OCZ) is characterized as rocky to sandy to muddy coastline. Rocky coast can be observed along Barangays Dimaluna, Malaubang and some portions of Barangays Sinuza and Tabid. Boulders of basaltic to andesitic rocks are found scattered along the coast. Barangays Maningcol and Pulot are typified by a sandy to silty coast. The intertidal zone within Barangays Mauswagon and Tabid and some parts of Barangay Dimaluna and Barangay Sinuza is generally blanketed by silty clay to mud deposits.

Coastal flooding in the OCZ is mainly controlled by seasonal variation. During Northeast Monsoon System (November to March), the wind-driven circulation of the bay is directed towards the coast. On the other hand, during Southwest Monsoon System (June to October), a general weak reversal in circulation occurs.

Areas in Ozamiz City prone to coastal flooding include Barangays Sinuza, Doña Consuelo, Dimaluna, Catadman, Maningcol, Pulot, Tinago, San Antonio, Baybay San Roque, Baybay Sta. Cruz and Baybay Triunfo. Built-up areas that cover former mangrove and/orswampy areas including most of Barangay Sinuza and Dimaluna are particularly prone to the hazard. These coastal barangays have elevations of less than 1.9 masl and are underlain by lahar deposits and recent alluvium.

Most coastal barangays in Ozamiz City have high population and so many dwellings were built very near the shore or on stilts on the bay itself. These houses are particularly prone to flooding and storm surges.

Flooding in these areas affects not only houses but the livelihood of the residents. In Barangay Pulot, crops and fishponds were destroyed by recent flooding events.

The seawall in Doña Consuelo built during the early 1990s was

damaged by coastal flooding.

2. Mass Movement

2.1. Mass movement (or mass wasting) is the downslope movement of bedrock, rock debris or soil due to gravity. It usually occurs when the shear stress exceeds the shear strength of material and usually occurs along a plane of weakness, i.e., a bedding plane, fault or joint. Majority of mass movement/slope failures/landslides


occur during times of heavy precipitation. Effective stress is reduced by any increase in water pressure and there is a consequent reduction in resistance to shear. Mass movement/landslides occur with increasing frequency in areas having progressively steeper slope angles.

Barangays Guingona, Guimad and Stimson Abordo (Montol) are

characterized by hilly to steep or 11.9 – 28.8 slopes while Barangays Pantaon and Bongbong are characterized by gently sloping terrain. These areas are underlain by volcanic deposits and are prone to landslide especially during periods of high precipitation.

Barangays Guingona and Stimson Abordo (Montol) were

classified as having moderate landslide susceptibility. According to interviews, threecasualties were reported in the 1987 landslide in Purok 7, Barangay Stimson Abordo (Montol) after a hurricane. In Barangay Guingona, a landslide near Purok 3 in 2000/2001 damaged cornfields and killed farm animals.

A landslide was observed along Sebasi River in Barangay

Stimson Abordo (Montol). Barangay Guingona is characterized by steep slopes.

Barangays Guimad and Pantaon were classified as low-moderate in terms of landslide susceptibility. According to residents, in 1990, a small landslide occurred near the elementary school in Barangay Guimad. Cracks appeared behind the school but after several years, these cracks have been filled up and are now covered by vegetation.

During the time of the survey, a small landslide was also

observed along the river on the way to Barangay Guimad. Fortunately, this area is uninhabited. In Barangay Pantaon, a landslide in 2003 damaged two houses in Purok 4.

Parts of Barangay Bongbong, particularly the Ozamiz City Socialized Housing Project is prone to landslide hazard. The slopes near the housing project are steep and are composed of highly weathered pyroclastic rocks.

3. Subsidence and Liquefaction

Subsidence is the lowering of the earth’s surface caused by

such factors as compaction or settling, a decrease in groundwater due to extraction, artificial withdrawal of support or the development of caverns in areas underlain by limestone. Meanwhile liquefaction is a type of ground failure in which water saturated sediments turns from a solid to a liquid as a result of ground shaking often caused by an earthquake.


Based on previous geological coastal assessment, the city proper andits immediate vicinity particularly Barangay Maningcol are prone to subsidence due to settlement and liquefaction if induced by ground shaking such as earthquake. These areas are underlain by recent alluvium which are unconsolidated sediments composed mostly of clay, silt and sand. The water table is encountered at a level of less than one meter. Water saturated sediments are more prone to liquefaction. Former mangrove and swamp areas are also prone to liquefaction as they are underlain by water-saturated fine sediments. This includes most of Barangays Tinago and Doña Consuelo.
