Isikhala sikaLarsen C besifundelwe isikhathi eside, selokhu ipulatifomu yakwaLarsen A yawa ngo-1995, kwathi ngo-2002 uLarsen B. Phakathi nonyaka, 2017, kusuka ngoJanuwari kuya kuJuni ubude be-Larsen C crack bunyuke ngaphezu kuka-200km. Yayinamathiselwe kuleli zwekazi ngocingo oluwu-4,5km ububanzi, kwaze kwaba ekugcineni, phakathi kukaJulayi 10 no-12, lwaqhekeka ngokuphelele.

Lokhu okutholakale ngokudabukisayo sikuthola nge-satellite yeSentinel-1 ye-European Space Agency, okuyiyona esetshenziselwe ukuqapha ukwakhiwa kokuqhekeka kukaLarsen C ngonyaka odlule, nakwisathelayithi i-Aqua MODIS nethuluzi leSuomi VIRS, zombili kusuka ku-NASA.
