Antarctica france sized ice shelf makes daily jumps raising icequake concerns

Global warming is creating disastrous conditions for the earth. The steady temperature of the earth is affecting the frozen ice at the poles. Researchers have now seen an incident in Antarctica that is heartbreaking. Researchers say that a piece of ice like France in Antarctica is called Ross Ice Shelf, slipping several centimeters ahead once or twice a day. Researchers are saying that this speed in Ross Ice Shelf is produced by Whillans Ice Stream. It is a sharp flowing river of snow that sometimes gets stuck and then starts moving forward.
The latest discovery sheds new lights on the dynamics of the ice shelf, and exposes one aspect of it that was unknown earlier. Due to the climate change, now the question of Ross Ice Shelf remains stable for a long time is questioned. This research Geophysical research letters Has been published in

Usually all glaciers proceed with a fixed speed. But the wheelns run on the ice stream stop-end-go motion. It is stuck due to lack of water under it. Then when too much pressure is collected, it bursts completely and then moves forward. This process is something similar to earthquake, similarly these shocks push the ross ice shelf further.

According to the study, such shocks can weaken the Ross Ice Shelf. Ice shelf acts as a barrier to the flow of glacier. The glaciers flow towards the sea, and the ice shelf maintains it under control. But if Ross ice shelf is weakened and breaks into parts, the result can be revealed in the form of ice melting speed. If the snow melted rapidly, it will increase the sea level rapidly.

The research team emphasized that snow tremors, and fracture ice shelf are natural events. Nevertheless, the researchers will closely monitor this activity happening inside it whether it was broken. Because even before this it has happened with small ice shelf. The new study exposes the dynamic and complicated nature of the Antarctic ice shelf. This will prove to be very important in furthering research in this direction.
