Typhoon Nesat made landfall over Calayan Island, Philippines, on
October 16, 2022. Although the storm’s winds were not catastrophic,
extreme rains brought heavy flooding to northern Philippines,
especially the large island of Luzon and the small Calayan Island,
which sits about 190 miles (306 km) north of Luzon.

Today’s Image of the Day compares two false-color images of the
northeast tip of Luzon Island after the passage of Typhoon Nesat. Both
images were acquired by the Moderate Resolution Imaging
Spectroradiometer (MODIS) on board NASA’s Aqua satellite. The upper
image was acquired on October 17, as skies were beginning to clear.
Much of the northern coast was completely under water, and flood water
(which appears blue) is present more than 20 miles inland. The Cagayan
River had overflowed its banks, creating additional flooding near the
river’s course. The lower image was acquired on September 15, a month
before Nesat’s passage, showing a much different scene. The comparison
between the two dates is stark.

According to Agroinsurance, on October 19 damage to agriculture in the
Philippines from Nesat was estimated at 366,058,240 Philippine pesos.
This is equivalent to about $6,214,383 US dollars. It is also estimated
that 14,578 farmers had been affected, with over 19,000 hectares of
crops damaged. Cagayan Valley suffered the greatest agricultural loss.
