Authorities have warned people on the island of La Palma of fresh dangers after a new volcanic vent blew open and rivers of unstoppable lava flowed towards more densely populated areas and the sea.
Residents have been cautioned about earthquakes, toxic gases, volcanic ash and acid rain after several small earthquakes shook the Spanish island, which sits in the Canary Islands archipelago off northwest Africa.
How bad has the damage been?

The volcanic eruption on Sunday afternoon forced the evacuation of 6,000 people and unstoppable rivers of molten lava have destroyed around 350 houses and caused significant damage to banana plantations, schools and infrastructure.
The island of 85,000 people is a popular tourist destination for Europeans.
Thousands of small earthquakes have happened in the days following the eruption.

How long will the eruption last?
The aftermath of the volcanic eruption could last for up to 84 days, the Canary Islands Volcanology Institute has said.
It based its calculation on the length of previous eruptions in the archipelago.

On Tuesday a new volcano vent opened up 3,000ft north of the Cumbre Vieja ridge, where the first eruption happened on Sunday.

The flow of lava has slowed significantly, making it ambiguous whether it will fan out across land and destroy more homes or flow into the sea.
A day after the eruption on Sunday it moved at 700m (13ft) per hour, but has since slowed to four metres (13ft) per hour.

But as the lava slowed, it has grown thicker, rising up to 15m (50ft) high in some places. It now covers some 166 hectares (410) acres.
Angel Voctor Torres, the head of the Canary Islands government, said on Tuesday that there would be a “critical moment” when the lava reaches the sea.

The rivers of molten rock have a temperature exceeding 1,000C and could cause explosions and produce clouds of gas when they meet the sea.
Mr Torres reminded locals of the island’s last eruption in 1971, when one person died after inhaling the gas emitted as lava met the water.
What dangers lie ahead?

A change in wind direction on Tuesday blew volcanic ashes, which irritate the eyes and lungs, over a vast area on the western side of the island.
Authorities have warned people to clean food and clothes to avoid ingesting the toxic ash.
The volcano has also been spewing out 8,000 to 10,500 tons of sulfur dioxide, which also affects the lungs, every day, according to the Volcanology Institute.

However, the Canary Islands’ chief vulcanologist, Miguel Angel Morcuende, said the levels of toxic gases currently being emitted were not dangerous for humans.
“There is no problem with the sulphur levels,” he said. “The readings being taken are not dangerous for human health.”

However, a thick plume of cloud has spread some 2.6 miles (4.2km) into the air, raising concerns around visibility for pilots.
The island’s airport remains open but authorities have told flights to stay away from the eruption site.

Winds are expected to push the cloud eastward over the rest of the Canary Islands, the Iberian peninsula and the Mediterranean, according to the European Union’s Copernicus Atmosphere Monitoring Service.
How is the government helping?

Mr Torres described the region as a “catastrophe zone” and said he would request funding to rebuild roads, water pipes and create temporary accommodation for families who have lost homes and their farmland.
