More than a week later Volcano The islanders of La Palma, who erupted in a magnificent exhibition of lava, are threatened with the new danger of poisonous gas and particles produced when volcanic streams spill into the sea.
Authorities have opened doors and windows to residents of the Spanish island, one of the Canary Islands, about 60 miles (100 km) from the coast of West Africa, to prevent potentially dangerous clouds from occurring. I told him to seal it with tape and a wet towel. When melted lava is poured into the sea.
Lava is essentially lava and is estimated to be around 2,200 degrees Fahrenheit (1,200 degrees Celsius). Suddenly cooled by seawater creates dense clouds of “lava,” a combination of lava and haze, which contains dangerous amounts of hydrochloric acid, says volcanologist Robin George Andrews. Told the BBC “Obviously, it’s not good to take a breath.”
When very hot lava hits seawater, the heat splits the water molecules into hydrogen. air Aeon; NS hydrogen Next, it combines with chloride ions dissolved in seawater to form hydrochloric acid. Vapors from this acid are dangerous to inhale. The resulting cloud of laziness also contains shards of volcanic glass and particles of ash. These are small enough to stay in the air and enter a person. lung..
No one has yet been injured by the laziness of the recent eruption of La Palma, but it can be fatal. United States Geological Survey (USGS), two people were killed in Hawaii in 2000 after they inhaled acidic vapors.
In addition to the risk of choking, clouds of laziness can irritate the skin, eyes and airways. Also, hot lava mixed with relatively cold seawater can cause dangerous explosions. Reported by USGS..
According to Josemangas Vinuela, a geologist at the University of Las Palmas on Gran Canaria, another city in the Canary Islands, the island began to form in the Atlantic Ocean over 150 million years ago, perhaps as a volcanic “plume” or “hotspot.” Is above. “It’s not just the Earth’s mantle under the ocean, but probably another type of mantle anomaly, disruption between structural plates, or other causes,” Viñuela said in a study published on a scientific website. Said MantlePlumes.org..
Over time, older islands such as Tenerife and Gran Canaria are drifting almost east of the mantle features that cause volcanic activity, resulting in less volcanic activity today. However, La Palma, northwest of the group, is currently the most volcanic.
Since the record began in the 15th century, eight volcanic eruptions have occurred in Cumbre Vieja (meaning “old peak”), the main mountain range and volcano of La Palma.
The last eruption before this eruption occurred in 1971, killing a fisherman who was suffocated by smoke (probably laziness) when he was too close to the lava stream.
The latest eruption began on September 19, when the Cumbre Vieja crater erupted lava. The lava began to flow downhill down a stream up to 2,000 feet (600 meters) wide and reached the sea on Tuesday (September 28).

The BBC reported that three coastal villages were blocked in anticipation of lava contact with water, but otherwise Lapalma officials downplayed the threat of toxic gas.
Currently, about 85,000 people live in La Palma. Approximately 6,000 people were evacuated to keep them safe during the recent eruption, which covered more than 470 acres (190 hectares) of land with lava and destroyed more than 650 homes.
