Volcano razes hundreds of buildings on Spain’s island

LOS ARIDANE: A vast wall of molten lava creeping down the slopes of Spain’s La Palma island has now destroyed 320 buildings, as distraught residents watched the flow inching towards the sea on Wednesday.

The Cumbre Vieja volcano erupted on Sunday in the south of La Palma, one of seven islands that make up the Canary Islands archipelago off the coast of Morocco.

The EU’s Copernicus observation programme said the lava now covered 154 hectares and had destroyed 320 buildings, double the figure it had given 24 hours earlier.

Experts are expecting the number to rise as the slow-moving mass slides towards the island’s western coast, when its interaction with the sea is likely to cause explosions and trigger toxic gas emissions.

So far, 6,100 people have been evacuated, among them 400 tourists who were taken to the neighbouring island of Tenerife, the Canaries regional government said.

Although there have been no casualties, the damage to land and property has been enormous, with the Canaries regional head Angel Victor Torres estimating the figure to be well over 400 million euros ($470m).

In a desperate attempt to divert the flow, firefighters could be seen using heavy machinery to dig a channel towards a nearby ravine as the advancing lava glowed in the background.

“It’s not for a want of trying,” they tweeted alongside a video of the digger hard at work.

Experts working on the Pevolca volcanic emergency plan say there are two lava flows: one to the north and one further south, which is barely moving.

David Calvo, an expert with the Involcan volcanology institute, said the lava had “slowed down a lot because it is reaching a very flat area but it is gaining height. There are areas where it is already 15 metres thick”.

If the lava — which has a temperature of 1,100 degrees Celsius — continues to move at the same pace, it will reach the sea by Thursday.

And when it gets there, there will be “a huge battle of the titans between the water and the lava,” he said. “With those contrasting temperatures, it causes massive explosions and a fragmentation of the lava which shoots out like missiles.”

Involcan experts witnessed the same phenomenon in 2018 at the Kilauea volcano in Hawaii where 16 people were hurt by the explosion of fragments and one person “almost lost a leg”, he said.

When the lava reaches the shore, it will also send clouds of acidic, toxic gas into the air, generated by the interaction with the seawater, which can be dangerous to inhale, experts say.

The volcano was also putting out some 10,000 tonnes of sulphur dioxide emissions per day which showed “the pace, the intensity of the eruption is not going to decrease”, Calvo said.
