sanfrancisco 41 mins ago Todok, Canary Islands-A small Spanish island in the Atlantic Ocean struggles days after a volcano erupts, forcing thousands to evacuate and officials warn that further danger from the explosion awaits. doing. Let’s take a look at the volcanic eruption of La Palma and its consequences. Where did the volcano erupt? The eruption occurred on Sunday afternoon in La Palma, one of eight volcanic islands in the Canary Islands archipelago of Spain, which stretches along the northwest coast of Africa. It was the first volcanic eruption in 50 years for an island with a population of 85,000. A magnitude 4.2 earthquake was recorded before the eruption. After a week of thousands of small earthquakes, a huge eruption of black and white smoke erupted from the ridge of Kumbrevieha volcano. An unstoppable river of lava up to 6 meters (20 feet) high now runs downhill towards the sea, swallowing all of its path. The Canary Islands are a popular volcanic hotspot for European tourists due to their mild climate all year round. Mount Teide on the nearby island of Tenerife is one of the tallest volcanoes in the world and the highest mountain in Spain. In La Palma, people live primarily in agriculture. What is the cause of the eruption? Scientists carefully monitored the accumulation of underground magma in La Palma during the week before the eruption and detected more than 20,000 earthquakes. This is too small to feel. This is known as an “earthquake swarm” and may indicate an approaching eruption. Three days before the eruption, the Canary Islands Volcanic Institute reported that 11 million cubic meters (388 million cubic feet) of molten rock had been pushed into Cumbrevieja. After a magnitude 4.2 earthquake, two crevices blew bright red magma into the air. Lava ran down the slopes of the mountain. How terrible was the damage? Close scientific surveillance meant that authorities could quickly evacuate people when the volcano erupted and no casualties were reported. However, the damage to property, infrastructure and agricultural land was enormous. So far, the eruption has destroyed about 190 homes and forced 6,000 people to evacuate. Melted rocks also embed banana groves, vineyards, avocado and papaya crops. Some irrigation networks were lost, groundwater was polluted, and roads were blocked. Lava rivers are now moving towards the island’s populated coasts and the Atlantic Ocean, where they can pose new problems. What is the danger now? Authorities say residents will face many dangers in the coming days and weeks. When lava reaches the Atlantic Ocean, it can cause an explosion and create a cloud of poisonous gas. Scientists monitoring lava measured lava at temperatures above 1,000 degrees Celsius (above 1,800 degrees Fahrenheit). The last eruption of the island in 1971 killed one person after inhaling the gas released when the lava hit the water. The island’s earthquakes continue, rattling nervous residents. After the Canary Islands Volcanology Institute said it was a magnitude 3.8 earthquake, a new rift opened at the end of Monday and began to erupt more lava. Scientists say more new lava spouts and cracks could emerge on Earth, endangering new regions. According to the Volcanology Institute, the volcano produces 8,000 to 10,500 tonnes of sulfur dioxide per day. Sulfur dioxide is odorous and irritates the skin, eyes, nose and throat. It can also cause acid rain and air pollution. The eruption also produced volcanic ash that could cause respiratory problems. La Palma officials have told people in large areas where the ashes had fallen to stay indoors with the doors and windows closed. How long will the eruption last? Scientists say the lava flow in Lapalma can last for weeks or months. The last eruption on the island was in 1971 and lasted for over three weeks. The last eruption across the Canary Islands occurred underwater off the coast of El Hierro in 2011. It lasted 5 months. Copyright © 2021 By AP communication. all rights reserved.
