Thousands of small earthquakes have hit the Canary Island of La Palma in recent days, while the authorities claim they have strengthened and moved closer to the surface.
As the quakes intensified and moved closer to the surface, the Canary Islands regional government put the island on a yellow alert for an eruption on Tuesday, the second of a four-step alert system.
The “earthquake swarm” is also likely to escalate, authorities said.
The authorities said the situation could change “in the near term,” but authorities said they had no indication that the latest outbreak was imminent, since the Scientific Committee for the Special Response to Disaster Control Plan said Thursday the number of earthquakes and their intensity had decreased.
More than 100 million cubic metres of magma have entered Cumbre Vieja in recent days, swelling the summit by 100 millimetres, the Canary Islands Volcano Institute said on Thursday.
