But the volcano emissions are a big problem for flights to and from all the airports. Ash cloud disrupted air traffic on the neighboring island of Tenerife and forced flight delays.
Airlines flying to the Canary Islands are advised to load extra fuel. It is anticipated that planes may have to change course or delay their landings because of air quality issues, said a spokesman for Enaire, the navigation control agency for Spanish airspace.
Canary Islands Volcano seismic intensity increases
On Saturday there were 37 seismic movements. The largest was measured at 4.1, according to the Spanish National Geological Institute. There has been a steady increase in seismic activity on the island. The number of earthquakes and their magnitude are more frequent and have a higher intensity.
Lightning flashes have been seen near the eruption activity. A study published in 2016 by the journal Geophysical Research Letters found that lightning is often produced during volcanic eruptions. The phenomenon is caused when ash particles collide and create an electrical charge.
