Satellites have been watching because the Cumbre Vieja volcano towering over the Spanish island of La Palma erupted for the primary time since 1971 on Sunday (Sept.19), forcing evacuation of hundreds of residents and vacationers.
The European Sentinel-2 Earth-observing satellite imaged the eruption because it flew over the volcano on Monday (Sept. 20) and captured the plumes of smoke and streams of lava spilling from the volcano in the direction of the western flank of the island, which is a part of the Canary Island archipelago situated off the coast of Morocco.
Sentinel 2 is a part of the European Union’s Earth commentary program Copernicus. Scientists working with information from this system as a part of the E.U. Copernicus Emergency Management Service revealed on Wednesday (Sept. 22) that lava from the eruption had already destroyed 320 buildings within the Los Llanos de Aridane area within the western a part of the island. The boiling lava, which is slowly spreading in the direction of the coast, now covers an space of greater than 0.6 sq. miles (154 hectares).

More than 6,000 individuals have been evacuated and additional evacuations are into consideration as geologists concern the lava may set off harmful explosions and launch poisonous gasoline as soon as it reaches the coast and mixes with the seawater, in line with The Independent.
Scientists are additionally persevering with to observe the unfold of the sulfur dioxide-rich volcanic smoke launched by the eruption. According to the Copernicus Atmosphere Monitoring Service (CAMS), the plume will unfold northwards from the island within the coming days and transfer over Spain and France by the top of this week.
Since the eruption began, determined residents, rescue employees in addition to information crews have shared photographs and pictures of the injury attributable to the slow-moving however unstoppable river of boiling lava.
Twitter person @UK_Expat shared drone footage of swimming pools boiling because the scorching lava spilled inside.
Another person, known as @ezequieleg968, shared scary footage of the lava slowly creeping into the garden of a home.
Volcanic ash from the eruption has to this point solely prompted restricted restrictions on air visitors on the island. According to the Volcanic Ash Advisory Center, satellite photographs reveal the presence of volcanic ash within the ambiance so far as 34 miles northwest of the eruption website. No widespread air visitors restrictions are presently anticipated.
The Geostationary Operational Environmental Satellite (GOES) East, operated by the U.S. National Oceanic and Atmospheric Administration (NOAA), which covers principally the japanese a part of the Americas, additionally managed to seize the eruption from its altitude of twenty-two,000 miles (36,000 km). The satellite’s infrared photographs are revealing the thermal signature of the eruption.
Cumbre Vieja’s final eruption happened in 1971. That eruption, nevertheless, was much less vital than this present one and was not accompanied by Earth tremors. This time, geologists had detected over 22,000 minor earthquakes inside one week previous to the eruption, which alerted them to the rising magma contained in the volcano.
The Cumbre Vieja volcano can be the topic of a controversial scientific concept that predicts that in some unspecified time in the future a strong eruption will break up the La Palma island, sending a large landslide into the ocean. This concept, revealed in 2001 within the journal Geophysical Research Letters, predicts {that a} 35 to 120-cubic-mile (150 to 500 cubic kilometers) chunk of the island might fall into the Atlantic Ocean, sending a tsunami as tall as 82 ft (25 m) into the U.S. Eastern Coast.
More recent studies, nevertheless, counsel that within the worst case, 19 cubic miles (80 cubic kilometers) of rock may slide off the volcano throughout a violent eruption, producing a wave that might be not more than 6.5 ft (2 m) tall by the point it reached the U.S.
Several scientists have spoken up publicly for the reason that present eruption began, attempting to dispel the issues.
“The current eruption at La Palma? It’s very, very likely to remain a local hazard,” volcanologist and science journalist Robin George Andrews posted on Twitter. “So don’t buy into any fearmongering.”
