Assessments are underway into the damage caused by a landslip at Bonchurch, which has destroyed gardens behind popular Isle of Wight cafe, Smugglers Haven.
The residents of 20 homes have been evacuated and Leeson Road, on the Island's south east coast, has been closed.
There are fears for property on the south side of the road, between Bonchurch Shute and Bonchurch Road.
A car and shipping container - and the land they were standing on - sank around 70 feet on Sunday night, at around 9.20pm, when part of the cliff behind Smugglers Haven cafe completely collapsed.
Further along the road, more gardens were destroyed, sinking as much as 40 feet, and leaving a sheer drop behind.
The Isle of Wight Council's former land manager, Matthew Chatfield, has told the County Press he now fears for the future of land below the affected gardens, which is owned by the local authority and cared for by Gift To Nature.
In June, the County Press confirmed the continued closure of the well-known beauty spot, the Devil's Chimney.
At the time, a County Hall spokesperson said the public footpath (V65C) was unsafe, after significant movement to the concrete steps and a landslide at the top.
A set of timber steps on the path were also damaged.
The path did not open across the summer season.
Calling the route 'characterful and challenging', Matthew Chatfield said, "this slip shows the decision to close Devil's Chimney was appropriate."
He warned it may not be possible to reopen it, adding another cut through nearby may eventually be accessible, after safety checks have been completed.
In the meantime, he has warned walkers not to use the site and to avoid the the stretch of coastal path, which runs below it.
Also threatened is a 20th-century shelter on Parapet Walk, which he describes as a lesser-known feature of The Landslip nature reserve.
Further east, a Victorian folly call The Lookout could also be affected.
What is the Isle of Wight Landslip at Bonchurch?
- Although it is possible the area known as The Landslip is actually thousands of years old, it became best known after big landslides in 1810 and 1818
- In 1955, there was a further slip
- The area is now picturesque woodland, criss-crossed with paths and boasting views of the English Channel
- Popular with walkers, it runs along the Island's south coast
Emergency crews remain on the scene this morning (Monday) and Leeson Road is closed. Buses are diverting and are not stopping at some stops in Shanklin, as a result.
