La Palma volcano eruption: Several earthquakes shake Spanish island amid fears lava flow could create acidic steam when it hits ocean

The flow of molten rock, which has led to tourists and thousands of people being evacuated from their homes, is advancing more slowly than expected but could cause clouds of acidic steam when it reaches the coast.

Volcanic eruption in La Palma

Several small earthquakes have shaken the Spanish island of La Palma as lava from a volcano eruption flows towards the ocean where it threatens to create clouds of acidic steam.

A new volcano vent 3,000 feet north of the Cumbre Vieja ridge, where the first eruption happened on Sunday, has also blown open on Tuesday.

The initial eruption followed a week of thousands of small earthquakes.

That so-called earthquake swarm gave authorities on the island off the African coast a warning that an eruption was likely and allowed more than 5,000 people to be evacuated, avoiding casualties.

Around 6,000 people have now been evacuated, including tourists, and 150 homes have been destroyed since the eruption on Sunday night.

Lava oozes down La Palma's streets

A new stream of lava later erupted from the volcano, prompting the evacuation of more residents in El Paso, on the island of La Palma.

The new fissure has opened after what the Canary Islands Volcanology Institute said was a 3.8 magnitude quake on Monday.

Streams of molten rock were initially expected to reach the Atlantic Ocean on Monday night but have since slowed, officials said.

Explosions and clouds of acidic steam are expected when the lava meets the water, although it is unclear when this will happen.

Lava with a temperature of more than 1,000C (1,800F) was still flowing at 700 metres (2,300ft) per hour on Monday, according to the Canary Islands Volcanology Institute, but mostly through unpopulated areas.

Lava was sent hundreds of metres into the air, engulfing forests and sending molten rock towards the ocean over a sparsely populated area of La Palma, the northwesternmost island in the Canaries archipelago.

No fatalities or injuries have been reported but drone footage captured two streams of black lava cutting a devastating swathe through the landscape as they advanced down the volcano's western flank towards the sea.

The four villages evacuated on La Palma include El Paso and Los Llanos de Aridane, with temporary shelters set up to house displaced residents.

Mariano Hernandez, president of La Palma island, urged people to stay away and described the scene as "bleak".

He said a wall of lava six metres (20ft) high "is consuming houses, infrastructure [and] crops in its path to the coast".

A Reuters witness saw the flow of molten rock slowly tear its way through a house in the village of Los Campitos, igniting the interior and sending flames through the windows and onto the roof.

Spain's tourism minister faced criticism after telling a local radio station the eruption was an opportunity to attract visitors to the island.

"The island is open," Reyes Maroto told Canal Sur radio, calling the sprays of lava "a wonderful show".

"There are no restrictions on going to the island... on the contrary, we're passing on the information so tourists know they can travel to the island and enjoy something unusual, see it for themselves," she said.

About 360 tourists were evacuated from a resort in La Palma following the eruption and taken to the nearby island of Tenerife by boat on Monday, a spokesperson for ferry operator Fred Olsen said.

Another 180 visitors were facing the same prospect. Meanwhile, local airline Binter cancelled four flights to and from the neighbouring island of La Gomera.

La Palma had been on high alert after more than 22,000 tremors were reported in the space of a week.

Cumbre Vieja is part of a chain of volcanoes that last had a major eruption in 1971, and is one of the most active volcanic regions in the Canaries.

It lies in the south of La Palma, which is home to around 80,000 people.

Itahiza Dominguez, head of seismology at Spain's geology institute, told Canary Islands Television that although it was too early to tell how long the eruption would last, previous eruptions had lasted weeks or even months.

Scientists said the lava flows could last for the same amount of time, but that the immediate danger to local people appeared to be over.
