The crack remained dormant for decades, stuck in a section of the ice shelf called a suture zone, an area
where glaciers flowing into the ice shelf come together.
There is a potential difference between the two, in glacier such as most marine terminating outlet glaciers,
where the glacier flow is rapid, acceleration results from retreat and thinning.
