    Severe monsoon rains have battered Pakistan since mid-June 2022,
    creating a massive disaster that has affected about 30 million people.
    According to the Pakistan National Disaster Management Authority
    (NDMA), as of August 29 an estimated 1,136 people have died since June
    14 and additional 1,634 have been injured. Floodwaters have damaged
    more than 3,400 km (2,113 miles) of roads—more than the straight-line
    north-to-south distance across the United States from its border with
    Alberta, Canada and the Mexico border. The NDMA reported that 162
    bridges and 170 shops have been damaged and 735,375 livestock have
    died.

    Reliefweb, a publication of the UN Office for the Coordination of
    Humanitarian Affairs (OCHA) states that floods have affected
    Balochistan, Sindh, Gilgit-Baltistan, Punjab, Azad Jammu and Kashmir,
    and Khyber Pakhtunkhwa (KPK) provinces of Pakistan. As of August 29,
    they report that around 1 million houses are totally or partially
    damaged, leaving behind millions in need of urgent shelter.

    The weather forecast calls for mainly dry weather over most of Pakistan
    for the next 24 hours. However, isolated thunderstorm activity and rain
    is expected along the upper catchment of all major rivers in the
    country, and this may add to flood conditions over the next several
    days.

    Today’s Image of the Day is a roll-over comparison of two false-color
    images of the Indus River and adjacent floodplain in the Sindh province
    of Pakistan. The two images were acquired by the Moderate Resolution
    Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite on
    two different days—August 27, 2022, and August 27, 2021. The comparison
    is provided by NASA’s Worldview App. To best use the roll-over feature,
    click on the arrow and slide your cursor to the right or left. Clicking
    on either image will allow moving only the image, with the comparison
    bar remaining stationary.

    This type of false-color image uses infrared and visible light (MODIS
    bands 7,2,1) to help distinguish water from land. Water appears various
    shades of blue, depending on depth and any sediment in the water, with
    the deepest water looking the darkest. Vegetation looks bright green
    while open or sparsely vegetated land looks tan. Cloud ranges from
    white to electric blue.

    These images clearly show the difference between the more normal
    monsoon season of 2021, when the flood plains near the Indus were green
    and the river remained within its banks, and the catastrophic and
    deadly inundation of the 2022 monsoon.
