At 17:30 UTC on February 13, 2014, the Suomi NPP satellite passed over the Indonesian island of Java, capturing the ash cloud emanating from the Mount Kelud volcano. Mount Kelud erupted just hours before, causing the evacuation of over 75,000 people, and impacting air travel in the region. Satellite analysis shows that the ash cloud is moving southwest into the Indian Ocean.
This false-colored image from the VIIRS instrument's infrared sensors on the Suomi NPP satellite shows the radial shape of the ash cloud. The yellow colors indicate higher, cooler cloud top heights. It is estimated that the ash extended 10 miles into the atmosphere.
