ISRO released images of Uttarakhand Glacier Burst.

10 February 2021.

Introduction:

The Indian Space Research Organisation (ISRO) has released the first images of the glacier burst in Uttarakhand.

Highlights:

According to the satellite images, the flash floods — reported in Rishi Ganga and Dhauli Ganga river catchment areas are a result of a major snow avalanche near Raini village of Chamoli district.
The power plants located at Raini and Tapovan suffered the maximum damage in the deluge.
The images were captured by the space agency’s advanced earth imaging and mapping satellite CARTOSAT-3.
CARTOSAT-3 is a third-generation agile satellite with high-resolution imaging capabilities.
A DRDO team is working along with ISRO scientists to ascertain the cause of the tragedy..
Scientists are investigating the cause of glacier break to be possibly an avalanche or a release of accumulated water.
According to experts climate change may be to blame since warming temperatures are shrinking glaciers and making them unstable worldwide.
A portion of the Nanda Devi glacier possibly burst through its banks at Joshimath, triggering an avalanche and a deluge that rippled through the Alaknanda river system in the upper reaches of the Himalayas .
It swept away a small hydroelectric project and damaged a bigger one downstream on the Dhauli Ganga.

It is an advanced Indian Earth Observation satellite.
The satellite has been built and developed by Indian Space Research Organisation (ISRO).
It replaced the IRS series.
The satellite comprises of a panchromatic resolution of 0.25 metres.
Thus, it is the imaging satellite having highest resolution in the world.
It has Mx of 1 metre with a high-quality resolution.

Satellite is used to map the weather, in the cartography or defence, and in the strategic applications
