I. Background

A. Chronology of Typhoon Kiko

- On August 3, 2009 at 10:00 AM, a low pressure area east northeast of Luzon developed into a tropical depression (TD) and was named "Kiko". TD Kiko developed into a tropical storm (TS) as it moved towards southern Japan and farther away from the country. However, on August 4, 2009, TS Kiko re-entered the Philippine Area of Responsibility moving in a west northwest direction and maintained its strength as it continued moving towards Taiwan

- It intensified into a typhoon with maximum center winds of 140 kph, gained more strength and slightly weakened as it moved closer to Taiwan. It slowed down while over the eastern coast of Taiwan and weakened as it made landfall over Taiwan.

- It weakened into a storm after interacting with the rugged terrain of Taiwan. Kiko continued to move slowly towards the southeastern China and accelerated as it moved out of the Philippine area of responsibility on August 7, 2009.

B. Emergency Incidents Monitored (25)

The southwest monsoon enhanced by Typhoon Kiko brought occasional to frequent rains over extreme Northern Luzon which resulted in the widespread flooding in northern and central Luzon; the occurrence of ten (10) landslide incidents in Baguio City, Benguet Nueva Ecija, Iloilo, and Negros Occidental ; the swelling of five (5) rivers; and the breaching of ten (10) earth dikes, retaining wall and sea wall to wit:

Landslides -10

Benguet - 4 (Itogon: Sitio Luneta, Brgy. Loakan; Brgy Ilod Poblacion; Brgy Gumatdang; and Brgy Kias in Iltogon) which resulted in the collapse of the Luneta Elementary School and riprap wall at Purok 2, Loakan; the damage of three (3) ball mills and five (5) houses

- The landslide site in Brgy Kias is a tri-boundary of Baguio City-Itogon-Tuba, Benguet Province. On 7 August 2009, undetermined number of small-scale miners from Emerald Mountain Explorers Association Inc. (EMEAI) was operating / manning 3 units of ball mills in their respective camps at Sitio Paltikan, Kias, Baguio City when suddenly a landslide occurred on top of Emerald Mountain upslope the miner's camps. Landslide materials such as mud, earth and boulders cascaded the mountain slope following a gulley which hit 3 miners' camps adjacent the Liwliw Creek . The ten (10) small scale miners who responded and proceeded to the landslide site to conduct rescue operations were hit by another wave of landslide coming from the crest of Mt. Emerald

Baguio City - 3 (Brgy Balsigan; Camp 8; and Camp 5) wherein the retaining wall along Brgy. City Camp Proper collapsed

Nueva Ecija -1 (along Maharlika Highway, Brgy. Putlan, Caranglan)

Iloilo - 1 (Tubungan , Iloilo Province) due to damming of water in the mountain of Pinihakan Daraga resulting to flashflood with muds from Maslog and Jar-ed Rivers thereby, affecting 362 families/1,701 persons with 273 families/1,138 persons evacuated to 25 evacuation centers

Negros Occidental - 1 (Sitio Manaol, Brgy San Quintin Remo, Moises Padilla) A ground movement of about 2 inches /15 minutes was observed with 700 hectares affected. A total of 65 families/325 persons were affected /evacuated to 12 evacuation centers. As per assessment of MGB VI, the mass movement in Brgy San Quintin Remo was caused by a combination of steep slopes, unconsolidated and muddy soil and rocks and the huge amount of water (rainwater and groundwater) in the landslide site.
