A volcano which has been erupting on the Spanish island of La Palma for two weeks has blown open two new fissures, sending more molten lava streaming towards the sea, as authorities warned that activity in the area was becoming “much more aggressive”.
The new vents, about 15 metres apart, have sent streaks of fiery red and orange molten rock down toward the sea in a parallel channel to the earlier flow that reached the ocean.
Miguel Angel Morcuende, technical director of the Canary Islands’ emergency volcano response department, said the volcano was “much more aggressive” now that it had been over the previous two weeks of eruptions.
A flow of magma which reached the Atlantic Ocean earlier this week has sent huge plumes of steam and other gases into the air.
Experts say that due to the huge difference in temperatures between the lava, the oceean, the magma is turning into glass below the surface of the sea.
A new area of solidified lava where the molten rock is flowing into the sea extends over more than 20 hectares.
Particles from the eruption have now reached the Azores, 1,500km away, causing a reduction in visibility, according to the Portuguese Institute of the Sea and Atmosphere (IPMA).
Strong winds have transported particles from the eruption to the Portuguese islands “in the form of sulphate aerosols”, the Portuguese agency said.
Overnight on Saturday, scientists recorded eight new earthquakes up to magnitude 3.5.
The country’s prime minister, Pedro Sanchez, will visit the Canary island on Sunday for the third time since the eruption, with the volcano showing no signs of slowing.
The eruption has sent gas and ash up to 6,000 metres into the air, officials said, and around 1,000 soldiers are working on the ground.
Officials are monitoring air quality along the shoreline but sulphur dioxide levels in the area do not represent a health threat, La Palma’s government said.
It recommended that people on the island wear face coverings and eye protection against heavy falls of volcanic ash.
The volcano has so far emitted some 80 million cubic metres of molten rock, scientists estimate – more than double the amount in the island's last eruption, in 1971.
The lava has so far destroyed or partially destroyed more than 1,000 buildings, including homes and farming infrastructure.
