LOS LLANOS DE ARIDANE, Spain (AFP) -- A volcano began spewing out ash again after a brief lull in the Canary Islands, where coastal residents are confined to their homes over fears of toxic gases when the lava hits the sea.
La Cumbre Vieja, which straddles a southern ridge in La Palma in the Atlantic archipelago, erupted on September 19, spewing out rivers of lava that have slowly crept towards the sea.
But on Monday morning, the lava and ash flow had stopped, and the week-long rumble of the eruption faded to silence, before resuming its activity several hours later, an AFP correspondent at the scene said.
Smoke had continued to emerge from the top during the lull. Several hours later, the volcano started pumping out ash again.
Speaking to AFP after the resumption, Involcan spokesman David Calvo said it was “just ash, for the time being”. La Cumbre Vieja had been switching between “explosive episodes and lulls for quite a while”, he added.
Overnight, 300 residents living in coastal areas were ordered to stay at home to avoid harm from the release of toxic gases when the lava finally reaches the sea, the regional government said.
The lava, moving very slowly, is currently between 800 and 1,000 meters (around half a mile) away from the shore, it said. An evacuation order affecting four areas is in place around Tazacorte, where it is expected to enter the sea.
Officials have also set up an exclusion zone to head off curious onlookers.
Experts say the entry of lava into the seawater will send clouds of toxic gas into the air, causing explosions and a fragmentation of the molten rock like gunshots.
The molten rock has so far scorched its way across more than 235 hectares of land, burning up many banana plantations, devoured 513 properties and destroyed nearly 20 kilometers of road, the European Union’s Copernicus Earth Observation Program said.
And eruption has so far force more than 6,000 people from their homes, although 160 were allowed to return home on Sunday.
The authorities also said clouds of ash from the volcano had started to affect areas on the eastern side of the island.
