The British woman killed by a landslide at a beach in Tenerife in the Canary Islands has been named by the Foreign Office as Marion O'Hara.
The accident happened shortly after 4pm local time at a small beach at Playa de los Gigantes.
The collapse of a 130ft stretch of cliff on to the beach killed another person and may have buried another two on the popular holiday island, a Spanish Interior Ministry spokesman said.
The local Civil Guard said the second victim was also female.
Diane Morris, who works at the nearby Bamboo Bar, said emergency workers were still at the scene.
She said: "There has been a lot of activity today with helicopters and there are still ambulances and fire engines down there.
"There has been a lot of speculation about it. Originally people said one person had died but now they are saying more.
"It is a little beach, more like a cove really, but its all taped off now."
A British holidaymaker said the area was known to be dangerous.
Howard Williams told Sky News: "Police were aware the cliff was dangerous for days, but the only thing they put in place was a bit of builder's tape."
