The eruption continues in a similar way as during the previous days. Lava fountaining with strong ash emissions as well as lava flows occurs from 3 main vents aligned in the crater, and tremor intensity has been more or less stable.
The new lava flows have not changed the flow field's surface significantly, but mostly overlap older flows, thickening it. A significant part of the erupted lava goes into a tube system that feeds the flow field downslope including the lava delta that mostly continues to grow slowly on its northern margin.
After a decrease yesterday, earthquakes under the central part of Cumbre Vieja volcano at 10-15 km depth have again picked up, and included the strongest-so-far quake at magnitude 3.9, which occurred 9 hours ago.
In total, IGN registered 32 quakes of magnitudes 3.0-3.9 and 54 quakes of magnitudes 2.0-2.9 during the past 24 hours.
