A volcano on La Palma, Canary Islands, Spain, released a lava fountain into the air on Sunday (September 19), forcing thousands of people to evacuate the area.
NS VolcanoThis eruption, called Lakunbre Vieja or “Old Summit”, last erupted in October 1971. At this time, lava was continuously poured from the volcano for more than 3 weeks. According to NPR.. This time, the volcano is expected to remain active only “for the next few days,” said President Angel Victor Toures of the Canary Islands. Reuters reported..
Some streams of lava are still spilling from the five fissures on the sides of the volcano. Lava flows, tens of feet wide, reportedly flooded many homes in the nearby town of El Paso, where residents were instructed to evacuate. In total, the eruption destroyed about 100 homes in a village near Kumbrevieja, BBC News reported.. No casualties have been reported.

“I can’t foresee someone else having to evacuate. The lava is moving towards the shore,” Torres said at a press conference on Sunday night. Expected to reach. According to Reuters.. At the time, experts estimated that about 600 to 706 million cubic feet (17 to 20 million cubic meters) of lava had flowed out of the volcano, he said.
Authorities warned last week that Lakumbrevieha could erupt soon, citing the fact that 4,000 small tremors have rocked the island since September 11. El País reported September 16th.
So-called earthquake These periods of herds and sustained seismic activity can sometimes imply that nearby volcanoes are preparing to blow. In this case, the sway is steadily approaching the surface, suggesting that the magma is moving upwards through the crust. In addition, officials said the ground began to expand near the site of the quake and had risen about 2.3 inches (6 centimeters) by September 16.
Based on this evidence, authorities have raised the risk of volcanic eruptions to yellow. This is the second highest in a three-tier system, El Pais reported. The quake could eventually “zero”, but Luca D’Auria, head of the volcano monitoring department at the Canary Islands Volcano Research Institute (Involcan), said the area affected by the eruption. He said he thought it was likely to occur in. trembling.

The next day, the quake became even more persistent. A week before the eruption, BBC News reported that a total of 22,000 tremors were finally recorded near the volcano. And on Sunday, D’Auria’s prediction came true and lava broke through the ground at Cumbre Vieja. Thankfully, authorities have already begun evacuating people and livestock from areas just around the volcano, Reuters reported.
Involcan Tweeted the video Dark smoke swirling from Kumbrevieja at 3:36 pm local time on Sunday. Immediately after that Volcanic Ash Advisory Center (VAAC) Toulouse reports The towering volcanic ash eruption was about 3,280 feet (1,000 m) above sea level and could be seen rising from the volcanic erupting lava fountain.
When lava flows surged across Lapalma Island, some news reports about the eruption raised concerns that the eruption could rush towards the eastern United States and send a “huge tsunami.” Newsweek reported..
The idea was originally born from a 2001 study published in a journal. Geophysics Research LetterThis suggests that if Kumbrevieha erupts again, a huge mass of volcano could suddenly collapse into the Atlantic Ocean. Volumetrically, chunks are 35 to 120 cubic miles (150 to 500 cubic kilometers) in size and can cause waves as high as 82 feet (25 m) to hit the US coast, the authors of the study said. I presumed that there was.
However, based on a recent study by Cumbre Vieja, experts have determined that such a monumental collapse is very unlikely, Dave Petrie, a landslide expert at the University of Sheffield. American Geophysical Union..recently the study suggestion In the worst-case scenario, about 19 cubic miles (80 cubic kilometers) of rock can slide off a volcano during a violent eruption, producing waves 6.5 feet (2 m) high before reaching the volcano. .. Eastern Seaboard.
“But the current eruption in La Palma is very likely to leave the area at risk,” said volcanologist and science journalist Robin George Andrews. Post to Twitter.. “So don’t buy to be afraid.”
