The eruption has been producing more ash today, generating a dense ash column rising several kilometers and drifting slowly towards the southeast, thus affecting again the airport.

Our correspondent Víctor Melo from the Volcanes de Canarias Association who is on location reports less vigorous explosions and lava fountaining compared to yesterday, but stronger ash emissions:
Volcanic tremor remains at similar levels as during the past day, although a weak decreasing trend continues. Lava discharge rates remain high, and the fronts near and at the coast have been reported to continue to advance.
Earthquakes continue at high numbers and with increasing magnitudes: the first few magnitude 4+ events occurred during the past 48 hours, but there is no trend visible as to their locations. They are still mostly at 10-15 km depth beneath the volcano's center and a few at deeper levels of around 35 km. So far, these quake do not suggest that new vents are about to form, but hint at continued magma supply from deeper reservoirs.
During the past 24 hours, there was 1 quake of magnitude 4.2, 22 quakes between 3.0 and 3.9, and 61 quakes between 2.0 and 3.0.
