At least one person is trapped under rocks after a landslide at a beach at Burton Bradstock.
Emergency services were called to the incident near the Freshwater Beach Holiday Park at about 12.30pm.
South West Ambulance Service said: "One person is reported as being trapped and the ambulance service is working in partnership with the other agencies on the scene to reach them as quickly as possible."
A spokeswoman for the coastguard said the landslide was about 400m from the park on the Jurassic Coast, which is popular with fossil hunters.
Witness Len Muggeridge, who was fishing off the coast, told Sky News: "Basically we heard a large thunder-like sound and we looked up and half of the cliff towards Freshwater had fallen down.
"Within 20 minutes there were people tramping over the top of it and then a second fall occurred.
"I would say somewhere in the region of about 30 or 40 tonnes of rock fell in the first fall and somewhere in the region of about 100 tonnes or more in the second fall."
In a joint statement Dorset Police and Dorset Fire and Rescue Service said: "Officers, with assistance from the police helicopter, are currently working alongside Dorset Fire and Rescue Service and other agencies to search the area.
"The Urban Search and Rescue Team (USAR) from Devon and Somerset has also been deployed to this incident. This is a national resource."
The Maritime and Coastguard Agency said three Coastguard rescue teams and the Coastguard rescue helicopter based in Portland are also at the scene in Lyme Bay.
