On November 7-8, 2013, Typhoon Haiyan slammed into the Samar
and Leyte provinces of the Philippines. One
of the hardest hit areas was the island of Leyte and its capital Tacloban
City. The Advanced Spaceborne Thermal
Emission and Reflection Radiometer (ASTER) instrument aboard NASA’s Terra
satellite collected these false-color (near-infrared, red, green) images of
Tacloban City before and after Typhoon Haiyan that are featured below.
The ASTER image on the left (before) was collected on November 14,
2010. In the before image the urban
areas appear blue-grey, with distinct urban patterns of blocks, streets, and
the Daniel Z. Romualdez Airport. The
vegetation appears bright red, and water is almost black. On the right is the ASTER image that was
collected after Typhoon Haiyan on November 15, 2013. The devastating typhoon leveled the city and
vegetation. Urban patterns were erased leaving
most of the city with a solid blue-gray appearance. Vegetated areas now appear light red where
vegetation was wiped out. Water still
looks black with visible pools of standing water on land.
