BCP Council is to carry out a full assessment after the second landslip on the same area of Durley Chine in the space of ten days.
The latest on Saturday pushed several beach huts across the promenade walkway.
It’s thought to have been caused by heavy overnight rain on Friday.
A section of the promenade has been cordoned off while the site is inspected.
Cllr Richard Herrett, Portfolio Holder for Destination, Leisure and Commercial Operations, BCP Council, said: “Following a visual assessment during the day of the slip, an extended cordon was implemented immediately in the interest of public safety, and special matting has been laid to enable wheeled and disabled access along the promenade.
“This area of cliffside has been inspected by the council’s Flood and Coastal Erosion Risk Management (FCERM) experts and Geotech engineer. Data gathered today is with our consultants now and we expect an update on these assessments nearer the end of this week, although cliff slip monitoring is an ongoing process.
“We have been in touch with the licensees of the beach huts and will continue to keep them updated.”
