From The Guardian: Iceberg size of Greater London breaks off Antarctica
From article: 'The 1,270sq km chunk separated from Brunt Ice Shelf near a British Antarctic Survey station on Friday
snip
The separation occurred just over 20km from Britain’s Halley research station but there was no one in the base and so there was no risk to human life. The 1,270 sq km, 150-metre-thick chunk of frozen water separated from the Brunt Ice Shelf on Friday.
The British Antarctic Survey (BAS), which has been operating Halley in a reduced role since 2017 because of the concern an iceberg could imminently split off, captured footage of large cracks at Antarctica’s Brunt Ice Shelf earlier in the month.
Large cracks in the ice of this part of Antarctica were first discovered a decade ago and, since then, the BAS has been monitoring the area in case of just such an event. BAS has a range of GPS devices on the Brunt. These relay information about ice movements back to the agency’s headquarters in Cambridge.'

They relocated the Halley VI station (built on skis, and designed to be moved) to avoid 'Chasm 1' to the west - this is to the north:
