Following the onslaught of STS Ineng in the country, Philippine Earth Data Resource and Observation (PEDRO) Center snapped satellite images over Ilocos Region, one of the hardest-hit by the storm.

The PEDRO Center was able to obtain pictures of some municipalities in Ilocos Norte after Ineng left the Philippine Area of Responsibility (PAR). The satellite images showed swollen rivers and possible flooded areas across the province.

Ineng left PAR evening of August 24, leaving damages in its wake. The storm also left two dead and two injured in Pasuquin and Laoag City, Ilocos Norte, according to the situation report of National Disaster Risk Reduction and Management Council (NDRRMC) as of 10:00 a.m., August 27.¹

According to the same report, Ineng affected 51,416 individuals in 208 barangays in Regions I, II and III, with around 58 houses damaged (24 totally damaged, 34 partially damaged) in six municipalities across Ilocos Norte.

Two images last August 25, 2019 by KOMPSAT-3 showed the swollen Bislak river that sits along the municipalities of Bacarra and Vintar. The blue color on the images indicates the water covered by the river during STS Ineng while the green color indicates the water covered before the storm. A total of 117 and 36 families were affected in Bacarra and Vintar respectively, according to the same report by NDRRMC.

Dove Satellite image last August 26 showed another neighboring river in the province. In the image, the Padsan river that runs along the municipalities of Sarrat, San Nicolas, Dingras and Laoag City was still swollen. The municipalities reported the number of families affected in their area: Laoag City with 3,693 families, San Nicolas with 2,363 families, Sarrat with 393 families and Dingras with 5 families.

Using Normalized Difference Water Index, the Dove Satellite was able to show possible flooded areas over Paoay, Ilocos Norte. The municipality reported 1,171 families affected by the storm.

The whole province of Ilocos Norte was put in a state of calamity last August 24 due to flooding and damage to infrastructure and agriculture.

Ineng first developed into a tropical depression east of Virac, Catanduanes last August 20 and left Philippine Area of Responsibility at 6:00 p.m., August 24 moving 25 km/h west northwest.²

The PEDRO Center gave copies of the satellite images to NDRRMC to help in assessing the damage from the tropical storm.
