La Palma volcano lava reaches sea, raising toxic gas fears

Lava from an erupting volcano in Spain's Canary Islands has reached the ocean, volcanologists said, raising fears of toxic gases being released as the molten magma hits the seawater.

The Spanish archipelago had earlier declared an exclusion zone of two nautical miles around the location the lava was expected to enter the Atlantic and asked residents to stay at home.

“The lava flow has reached the sea at Playa Nueva,” the Canary Islands Volcanic Institute (Involcan) said on Twitter Tuesday night.

La Cumbre Vieja volcano, which straddles a southern ridge in La Palma, an island with 85,000 inhabitants, erupted on September 19th, spewing out rivers of lava that have slowly crept towards the sea.

Television images showed a stream of glowing lava entering the water, creating a large cloud of smoke.

Residents of several areas of Tazacorte, a village near the coast, were told Monday to stay at home to avoid harm from the release of toxic gases that can take place due to a reaction between the 1,000 degrees Celsius (1,800 degrees Fahrenheit) molten lava and water.

On Tuesday afternoon, the slow-moving lava flow, which has varied in speed over the past few days, was still around 800 metres (half a mile) from the coast.

Residents were warned to stay home due to “the possibility that there will be a small shock when the magma enters the seawater, and that this small shock causes vapours which can be toxic,” stressed Miguel Angel Morcuende, technical director of the Canary Islands Volcanic Emergency Plan (Pevolca).

Homes destroyed

Experts say the entry of lava into the seawater could cause explosions and a fragmentation of the molten rock like gunshots.

“Inhalation or contact with acid gases and liquids can irritate the skin, eyes and respiratory tract, and may cause breathing difficulties, especially in people with pre-existing respiratory diseases,” Involcan warned.

The two last eruptions on La Palma, in 1949 and 1971, killed a total of three people, two of them from gas inhalation.

A state of natural disaster has been declared on the island, where the molten rock has so far scorched its way across more than 268 hectares (660 acres) of land and destroyed 656 buildings, according to the European Union’s Copernicus Earth Observation Programme.

The eruption has forced the evacuation of more than 6,000 people from their homes but has not killed or injured anyone.

The lava flow has destroyed several roads, with the Canaries regional head Angel Victor Torres estimating last week that the damage to land and property would exceed €400 million.

Since it erupted, the volcano has been spewing huge columns of smoke and ash reaching several hundred metres high, disrupting air traffic.

Domestic flights were cancelled on Friday and the airport was closed the following day.

The airport has since reopened but flights remain suspended.

Experts estimate the eruption could last for several weeks, or even months.

Like other islands in the archipelago off the northwest coast of Africa, La Palma relies mainly on the cultivation of bananas and tourism.

3,000 people in Spain’s La Palma forced indoors as lava reaches sea

Around 3,000 people were ordered to remain indoors on the Canary island of La Palma on Monday as lava from an erupting volcano reached the sea, risking the release of toxic gas.

The Canary Islands Volcanic Emergency Plan (Pevolca) “ordered the confinement” of residents of coastal towns and villages near where the lava cascaded into the sea, sending large plumes of white smoke into the air, local emergency services said on Twitter.

The order was given due to “the possible release of gases that are harmful to health,” it added.

The order affects “around 3,000” people on the island, Miguel Angel Morcuende, technical director of Pevolca, told a news conference.

This is the third time that a lava flow has reached the Atlantic Ocean since the Cumbre Vieja volcano in the south of the island erupted on September 19th, covering large areas with ash.

All flights to and from La Palma’s airport were cancelled on Monday because of the ash, the third straight day that air travel has been disrupted.

And for the first time since the eruption started, local authorities advised residents of La Palma’s capital, Santa Cruz de La Palma in the east, to use high-filtration FFP2 face masks to protect themselves from emissions of dioxide and sulphur.

Most of the island, which is home to around 85,000 people, is so far unaffected by the eruption.

But parts of the western side where lava flows have slowly made their way to the sea face an uncertain future.

The molten rock has covered 1,065 hectares (2,630 acres) and destroyed nearly 1,500 buildings, according to Copernicus, the European Union’s satellite monitoring service.

Lava has destroyed schools, churches, health centres and irrigation infrastructure for the island’s banana plantations — a key source of jobs — as well as hundreds of homes.

Provisional damage was estimated on Friday at nearly €900 million ($1 billion), according to the regional government.

The island of La Palma, part of the Canary Islands archipelago off northwestern Africa, is experiencing its third eruption in a century, with
previous ones in 1949 and 1971.
