SUMMARY REPORT

RESULT OF THE MGB GEOHAZARD ASSESSMENT COVERING THE EIGHTEEN (18) MUNICIPALITIES/CITY IN THE PROVINCE OF

In line with the Presidential Directive and NDCC resolutions following the February 17 Southern landslide incident, and the need to fast track the geohazard mapping program along the eastern seaboard of the , geologists from the Mines and Geosciences Bureau-Regional Office III (MGB-R3) conducted a geohazard assessment of the barangays in the municipalities/city n the province of Tarlac.

Each was classified according to their susceptibility to landslide and/or flooding. For landslide susceptibility, the rating parameters are as follows:

High • Presence of active and/ or recent landslides • Presence of numerous and large tension cracks along slope adjacent to the community and that would directly affect the community • Areas with drainages that are prone to landslides damming • Steep/Unstable slopes consisting of loose materials

Moderate • Areas with indicative and/or old landslides • Presence of small tension cracks along slope and are located away from the community • Moderate slopes

1 Low • Low to gently sloping • No presence of tension cracks

Each barangay was rated into low, moderate or high for flooding susceptibility with the rating parameters as follows:

Low • 0 – 0.5 meter depth of floodwaters

Moderate • 0.51 – 1 meter depth of floodwaters

High • > 1 meter depth of floodwaters

With regards to landslide susceptibility, the barangays assessed include areas that are located on and/or near slopes and riverbanks and have the potential for landslide occurrence. The rating of each barangay presented herein particularly refers to the barangay proper since majority of the population is located there. It should be noted, however, that the rating does not necessarily reflect those of the . Barangays with identified were presented with a Landslide Threat Advisory informing their susceptibility to landslides and the corresponding recommendations particular to the barangay.

The flood susceptibility of the barangays in the municipality was also assessed. Barangays classified with moderate to high susceptibility to flooding are located in identified low portions of the barangay, in topographically low-lying areas and/or near a major river system. These barangays were presented with a Geohazard Threat Advisory informing their susceptibility to flooding and the corresponding recommendations particular to the barangay.

6. Municipality of Gerona

• There are thirty three (33) barangays with low susceptibility to flooding (barangay centers and populated areas) in the municipality of Gerona (, Bularit, Luna, Matapitap, Singat, Oloybuaya, Plastado, Abagon, Caturay, Magaspac, San Antonio, Parsolingan, Cardona, Malayep, Amacalan, Calayaan, Padapada, Santiago, San Agustin, New Salem, Mabini, , Tangcaran, Sulipa, Villa Paz, Buenlag, Don Basilio, Dicolor, Pinasling, Apsayan, Poblacion 1, Poblacion 2 and Poblacion 3). Most of the purok affected with localized flooding are located in the low-lying portion of the barangay, do not have sufficient drainage and located near the creek/river systems traversing the barangay.

• The are seven (7) barangays experiencing different susceptibility to flooding from low, moderate to high depending on the topographic location (Carbonell, Salapungan, Ayson, Sembrano, Sta. Lucia, Danzo and Matayuncab). These are low-lying areas affected by the overflow from the creek/rivers and breaching of dike structures. Backflooding results from the inadequate drainage and exit points during unusually heavy rainy day and typhoon periods. Structurally controlled flooding such as elevated roads and road system with insufficient drainage, irrigation canals and excessive release of water from dams in the nearby municipalities of and is also a possible cause.

• The dike protecting the has some weak points along its length and for the past 10 years had history of breaching. Floodwaters enter the barangays adjacent to the river and/or dike and cause flash flooding to the barangays along the path. Barangays adjacent to the dike have low susceptibility to flooding; however, the risk of floods of greater than 1m is still present due to the history of the dike breaching at some points along its length (San Jose, San Bartolome, Tagumbao, Malayep, Ayson, Dicolor).

6 • The agricultural areas/farm lots have a moderate to high susceptibility to flooding.

• Localized flooding can be attributed to inadequate drainage system during periods of unusually heavy precipitation.

• For landslide susceptibility, there are two barangays with low susceptibility to landslides. The topography is generally gently sloping and no tension cracks were observed (San Agustin and Mabini).

7. Municipality of La Paz

• In terms of landslide susceptibility, no barangays in La Paz have the potential for landslide occurrence.

• There are two (2) barangays with moderate susceptibility to flooding (Mayang and Kapanikian).

• There are twelve (12) barangays with high susceptibility flooding (Lomboy, La Purisima, Macalong (New and Old), Lara, San Roque, Rizal, Balanoy, Caut, Bantog, Paludpud, San Isidro and Guevarra).

8. Municipality of Mayantoc

• In terms of landslide susceptibility, there are six (6) barangays in Mayantoc that have potential for landslide occurrences (Bigbiga, Binbinaca, Gayonggayong, Labney, Nambalan and Pedro L. Quines). The areas near the barangay proper have low to moderate susceptibility to landslides. The generally high and mountainous areas have a high susceptibility to landslides. There are areas in Brgy. Labney that are possible landslide debris accumulation zones. Evidences of landslides present include tension cracks, old escarpments, old landslides and rock fall.

7 flooding (Ambalingit, Binbinaca, Caocaoayan, Cubcub, Gayonggayong, Gossood, Mapandan, Nambalan).

• One (1) barangay has a moderate to high susceptibility to flooding (Baybayaoas). It is adjacent to the river and has a historical high level flood in 1972.

• One (1) barangay has a high susceptibility to flooding (Labney). It is located in the river floodplain.

9. Municipality of Moncada

• There are nine (9) barangays with Low susceptibility to flooding (Aringin, San Roque, Sta. Monica, San Leon, San Juan, Mabini, Maluac, San Julian and Poblacion 2). These barangays had a from low to moderate to high susceptibility to flooding during the 1972 Central Flood;

• Nine (9) barangays with Low to Moderate susceptibility to flooding (Atencio, Villa, Calamay, Lapsing, Tolega Norte, Burgos, Camposanto 1-Sur, Poblacion 4 and Poblacion 4);

• Eight (8) barangays with High susceptibility to flooding (Tubectubang, Ablang Sapang, Banaoang West, , Banaoang East, Baquero Sur, Camangaan West and Sta. Lucia East); and

• Six (6) barangays with Low, Moderate to High susceptibility to flooding (Camposanto Norte, Camposanto 2, Baquero Norte, Camangaan East, Capaoayan and Poblacion 1).

• Flooding in the municipality is influenced by different factors such as topographic location; insufficient and inadequate drainage system; clogged drainage canals; excessive surface runoff; overflow from the river; structurally controlled flooding such as elevated roads and highways, irrigation canals and excessive release of water from dams and water impoundments; artificial damming along waterways (irrigation system and natural river/creek channels) blocking the flow of the channels causing it to overflow its banks; and breaching of the dike protecting Tarlac River especially along the Colibangbang dike portion. Most of the barangays in the municipality of Moncada experience varying depths of floodwaters during the 1972 flood; hence, the same risks associated with that flood event could be expected.

• The following natural rivers and creeks usually overflow its banks and contribute to sheet flooding: Sta. Lucia River, Baca River, Bakit-Bakit Creek, Camangaan

8 River, Banaoang River, Nibulsa Creek, Sukulanat Creek, Umingan Creek, Tarlac River and ).

• The agricultural areas/farm lots have a moderate to high susceptibility to flooding.

• Localized flooding can be attributed to urban development and inadequate drainage system during periods of unusually heavy precipitation.

10. Municipality of Paniqui

• Six (6) barangays with Moderate to High susceptibility to flooding (Salomague, Cabayaosan, Apulid, Canan, Sta. Lucia and Apsayan);

• Four (4) barangays with Low, Moderate to High susceptibility to flooding controlled by topographic location (Matalapitap, Acocolao, Nipaco and Dapdap); and

• Three (3) barangays with High susceptibility to flooding (Coral, San Isidro and Sta. Ines).

• Some barangays adjacent to the Tarlac River have low susceptibility flooding since the dike is protecting the municipality from the overflow from the river; however, the dike is vulnerable to breaching and had a history of breaching along the weak points and avulsion side of the river such as in Sta. Ines, Ayson, Colibangbang and Nagcamarinan. The Tarlac River is also silted with materials and at some portion of the river the channel is higher than the barangay itself. Breaching of dikes along rivers in the province of Nueva Ecija also contribute to flooding in the municipality and vicinity.

• Flooding in the municipality is influenced by different factors such as topographic location; insufficient and inadequate drainage system; clogged drainage canals; excessive surface runoff; overflow from the river; structurally controlled flooding such as elevated roads and highways, irrigation canals and excessive release of water from dams and water impoundments; artificial damming along waterways (irrigation system and natural river/creek channels) blocking the flow of the channels causing it to overflow its banks; and breaching of the dike protecting Tarlac River. The barangays in the municipality of Paniqui with moderate to high susceptibility to flooding during the 1972 Central Luzon flood have the same risks associated with unusually heavy rains and flood event of similar gravity.

• The following natural rivers and creeks usually overflow its banks and contribute to sheet flooding: San Isidro River, Tablang River, Caturay Creek, Biniklatan Creek, Malasin Creek, and Tarlac River).

13. Municipality of San Clemente

10

• There are barangays in San Clemente that are located in and/or near slopes and have the potential for landslide occurrence (So. Dueg- high susceptibility to landslide; Casipo and Balloc-low susceptibility to landslide). • Based on outcrops and exposures and from excavated materials from dug wells, it appears that barangays Maasin, Bamban and Daldalayap are underlain by debris flow deposits consisting of matrix supported gravel to boulder clasts of gabbro and ultramafic rocks set in a clayey to sandy soil matrix. Past debris flows had been generated from the landslide prone areas of Canding-Batacan River and were deposited on these three barangays. • There are three (3) barangays with low susceptibility to flooding (Casipo, Balloc and Maasin) • There are two (2) barangays with low to moderate susceptibility to flooding (Poblacion Norte and Catagudinan). Agricultural areas of the barangay, identified low lying areas and those located near the creek/river channel has moderate susceptibility. • There are four (4) barangays with moderate to high susceptibility to flooding. The barangay has naturally low lying areas and portions located near active creek and river channels. Breaching of protective dike increases the susceptibility of the barangays to high level floods (Bamban, Daldalayap, Nagsabaran, Daclong 1 st ). • There are three (3) barangays with high susceptibility to flooding (Pitao, Daclong 2 nd , Poblacion Sur). These barangays are natural catch basins specially barangays Pitao and Daclong 2 nd which are also affected by over flowing of Agno River as in the case of release of excess waters from San Roque Dam during the October 2009 Typhoon Pepeng flooding. • Riverbank erosion was observed along Canding-Batacan River and natural channels traversing the municipality. • Siltation is also evident along active Canding-Batacan River which serves as the boundary with Mangatarem, Pangasinan.

14. Municipality of San Manuel

• There are eight (8) barangays with low susceptibility to flooding in the municipality of San Manuel (Salcedo, San Narciso, Mangandigay, Legaspi Matarannoc, Pacpaco, Poblacion, Sta. Maria).

• One (1) barangay (Villa Aglipay) has a high susceptibility to flooding. The barangay proper experienced 2-meters deep floodwaters in 1972.

It should be noted that these susceptibility ratings were arrived at as of this field assessment. However, the rating could advance (e.g., from low to moderate, and moderate to high) based on the present and historical accounts of the flood /landslide susceptibility in the municipality/city. Hence, the MGB constantly recommends strict and continuous monitoring of the barangays, continuing information and education campaigns on disaster preparedness, disaster risk management and mitigations; and strengthening of the Barangay Disaster Coordinating Council.

The matrices of the municipalities/city included in the assessment are in the compact disc as an attachment to this report.
