Earths Largest volcanic region found in Antarctica

Researchers from the University of Edinburgh in Britain have discovered the largest volcanic region on Earth, two km below the surface of the vast ice sheet in west Antarctica.

They have found 91 previously unknown active volcanoes in the region known as the West Antarctic rift system, adding to the exiting 47 volcanoes that were discovered earlier. This makes it largest volcanic region on the Earth.

Key Facts

These active peaks are concentrated in the west Antarctic rift system region — which stretches 3,500 km from Antarctica’s Ross ice shelf

to the Antarctic peninsula. The height of these newly discovered active volcanoes range from 100 to 3,850 metres, with the highest being almost as tall as Switzerland’s Eiger mountain (3,970 metre). All of these volcanoes are covered in thick layers of ice.

This region is larger than east Africa’s volcanic ridge which is currently rated as the densest concentration of volcanoes in the world. Any volcanic activity of Antarctic rift system may have crucial implications for the rest of the planet.

If one of the volcanoes in Antarctic rift system erupts, it could further destabilise west Antarctica’s ice sheets. If it causes the melting of ice on eruption may speed up the flow of ice into the sea. It will enhance sea level rises that are already affecting our oceans due to climate change.

Government launches nationwide campaign Gaj Yatra to protect elephants

The Union Ministry of Environment and Forest has launched a nationwide campaign Gaj Yatra to protect elephants. It was launched on the occasion of World Elephant Day observed on August 12.

The ministry also released the All India Census 2017 Report on elephants and Agreed Points of Action on Trans-Boundary Conservation of Elephants by India and Bangladesh.

Gaj Yatra Campaign

The campaign is planned to cover 12 elephant range states across the country. It is 15 months campaign the will be led by the Wildlife Trust of India (WTI). The ‘Gaju’ mascot, which was released by the Ministry in 2012, will be helm of the campaign.

The campaign aims create awareness about elephant corridors to encourage free movement in their habitat. During the period of the campaign, artists and craftsmen will create life-size works on the theme of elephants in places along the route of the roadshow using local art and craft. Specially fabricated vehicles will be also deployed to display these on pre-determined routes with campaigners.

World Elephant Day

The World Elephant Day is observed every year on August 12 to support various stakeholders involved in supporting various conservation policies to protect elephants. It also seeks to support stakeholders involved in improving enforcement policies to prevent illegal poaching and trade in ivory, conserving elephant habitats, providing better treatment for captive elephants and reintroducing captive elephants into sanctuaries.

The World Elephant Day was conceived in 2011 by Canadian filmmakers Patricia Sims and Michael Clark of Canazwest Pictures and Sivaporn Dardarananda, Secretary-General of Elephant Reintroduction Foundation of Thailand. Now it is supported by over 65 wildlife organisations and many individuals in several countries across the globe.

Elephants

As per the available population estimates, there are about 400,000 African elephants and 40,000 Asian elephants across the globe. Asian elephants are listed as “endangered” and African elephants are listed as “vulnerable” in the IUCN Red List of threatened species.
