New before and after satellite images on September 25 and 30 show the new headland formed by lava from the Cumbre Vieja volcano on the Spanish island of La Palma as it poured into the nearby Atlantic.
The Canary Islands Volcanology Institute (INVOLCAN) said on September 27 that lava and salt water would combine to form “water vapor filled with hydrochloric acid”.
The images show lava falling from the rock onto new land, described by Involcan as a “lava delta”.
Meanwhile, the erupting volcano opened two more cracks on its cone on Friday.
The new cracks, about 50 feet across, send streaks of fiery red and orange molten rock out to sea, paralleling an earlier current that reached the Atlantic Ocean earlier this week.
Miguel ngel Morcuende, technical director of the Canary Islands’ Emergency Volcano Response Department, said the volcano was “much more aggressive” about two weeks after it erupted on the island of La Palma.
Overnight scientists recorded eight new earthquakes of magnitude 3.5.
Officials said the explosion was sending gas and ash up to about 20,000 feet in the air.
The quick evacuation of more than 6,000 people helped prevent casualties since the September 19 eruption.
Officials were monitoring the air quality along the shoreline. The government of La Palma said sulfur dioxide levels rose in the area, but there was no health hazard.

Scientists estimate that the volcano has so far ejected about 80 million cubic meters of molten rock – more than twice the volume of 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, and covered about 709 hectares (1,750 acres).
La Palma, home to about 85,000 people who live mostly from fruit farming and tourism, is part of the volcanic Canary Islands, an archipelago off northwest Africa that is part of the territory of Spain.
The island is about 35 kilometers long and 20 kilometers wide at its widest point. Life has continued as normal on most of the islands while the volcano is active.
