The The Antarctic will soon lose a block of ice whose surface would be close to 1,700 kilometers square, according to NASA, which will generate an iceberg of a size twice as big as the city of New York.
The space agency said Friday in a statement that the block of ice would fall, produced a crack appeared in October 2016 and since then has gradually deteriorated. long and deep.
Although scientists did not specify when this would happen, they cautioned that this break-up could affect the rest of the continental shelf and, consequently, all stakeholders. scientific infrastructure he wants.

In its announcement, NASA compared a photograph of this area taken from the Landsat satellite in January 1986 with another, dating from January 2019, where it can be seen. a crack that runs from west to east all the part that will come off and that has the shape is that of a coastal cape.

When this crack meets another that crosses the tip from south to north, the territory will be converted into huge iceberg, whose direction is unpredictable, as well as the effect it will have on the rest of the surface of this region of Antarctica.
The second gap already existed and has remained stable for 35 years, NASA said, but its growth has accelerated suddenly and continues northward at a speed of more than 4 km per year.
The iceberg that will be born seems gigantic, but it is not for the Antarctic standards, specified NASA, although they admitted that "it will be important".
"This is perhaps the largest iceberg that has broken on the Brunt ice floe since the observations began in 1915," the space agency said on its website.
"Scientists are currently studying whether this loss would result in surface change and possibly instability or breakage," they warned.
Increasing fissures that fracture the surface of Antarctica are generated concerns about the safety of people working on the platform, especially researchers at the Halley station of the British Antarctic Survey.
This base, which is one of the main bases of investigation of the Earth, Atmosphere and Space sciences, generally operates all year round, but has been closed twice in recent years due to changes unpredictable ice.
