Incredible satellite image of Anak Krakatau eruption

NASA’s Earth Observatory released incredible images of Indonesia’s Anak Krakatau volcanic eruption which happened last week.

Taken with the the Operational Land Imager (OLI) on Landsat 8, the image shows the plume of smoke rising over its peak.

“The location of the plume suggests that it is volcanic in origin,” said Verity Flower, a USRA volcanologist based at NASA’s Goddard Space Flight Center in a statement.

Flower and colleges used the Multi-angle Imaging Spectroradiometer (MISR) sensor on NASA’s Terra satellite to measure the height of volcanic plumes and to observe the shape, size, and light-absorbing properties of the particles within plumes.

They believe that the plume is most likely comprised of water vapor and gas because of its white colour.

“Anak Krakatau volcano has displayed these small eruptive bursts periodically through the last few years,” Flower said. “However, it can also display more destructive activity such as tsunami-triggering eruptions.”

This volcano, located in the Sunda Strait, has had more than 50 known periods of eruptions in almost 2,000 years.

The most recent eruption included fountains of lava, lava flows and ash rain within the 2km radius of the crater.
