The advance of lava from a volcano on La Palma has slowed down, raising fears it will fan out across the island and destroy more homes instead of flowing into the sea.
As it slowed, the lava grew thicker. In places, it rose up to 50 feet high.
The lava now covers 410 acres and has swallowed around 350 homes.
The lava’s slowing pace meant more residents could retrieve their belongings, with the Guardia Civil police force escorting them to their homes in Todoque on Thursday morning.
The Guardia Civil said seismic activity in the area, which surged before the eruption and has remained strong, has stabilised.
Molten lava, ash and smoke continued to pour from the volcano’s mouth, shooting up to nearly 14,000 feet high, the Canary Islands Volcanology Institute said. That raised concerns about whether airspace above the island could remain open.
ENAIRE, which manages Spain’s airspace, said two areas above the affected area are being declared no-fly zones to allow emergency services to operate freely. Some flights into and out of La Palma were delayed early on Thursday.
The Emergency Military Unit deployed on the island said the readings it has taken of the air found no threat to health.
Authorities have not reported any casualties from the eruption, although damage to property, infrastructure and farmland is expected to be significant.
Scientists were monitoring the volcano and had warned of a possible eruption. That allowed almost 7,000 people to be evacuated in time.
Officials had initially expressed fears about what would happen when the lava reached the Atlantic Ocean. The lava which exceeds 1,000C (more than 1,800F), could cause explosions, trigger landslides and produce clouds of toxic gas when it hits the ocean, experts say.
Joel Francisco, 38, said he and his elderly parents had to evacuate the area around the village of Todoque in a rush, taking only a few belongings and important documents.
Now that the flow seems to have slowed, he hopes to go back and retrieve some more things in case the house is entombed in lava.
“We don’t know how long we have to wait until we can return to our homes because the roads are closed,” he said. “Some people have it worse off, their houses are gone.”
The eruption and its aftermath could last for up to almost three months, according to the Volcanology Institute.
Spain’s king and queen, and the Spanish prime minister, are due to visit the affected area.
Life on the rest of La Palma, which is roughly 22 miles long and 12 miles wide at its broadest point, has been largely unaffected, with undeterred tourists landing for previously scheduled holidays.
