Bournemouth Borough Council has said that assessment of a 250m section of East Cliff continued over the Bank Holiday weekend following a landslide at the site a week ago.
“Engineers have installed up to 40 monitoring points along an area of East Overcliff Drive 120m either side of the landslip,” said council head of operations Chris Saunders.
“These monitoring points will take detailed measurements over a number of days, which should indicate the likelihood of further movement.”
The landslide on 24 April severely damaged an Edwardian-era funicular railway and destroyed a block of toilets at the foot of the cliff.
Saunders has said that this monitoring data will be used along with historical information to inform decisions about site clearance and longer term action at the site.
“Pedestrian access to the footway in this area is being restricted in order to maintain the sterility of the monitoring points and minimise the risk of disturbance,” added Saunders. “Signage on site has been erected to keep the public informed.”
The council has declined to comment on the cause of the recent stability problems or possible courses of action but it has been suggested by industry experts that regrading of the cliff face may be necessary to prevent further failures.
