Not much has changed at the ongoing eruption. The main vent at the crater emits near-continuous jets of ash-rich fountains while modest amounts of lava flow from lower vents into a channeled surface flow on the western flank of it.
Volcanic tremor as an indicator of magma flow rate has decreased a bit, but remains high. No significant changes in earthquake activity or ground deformations can be reported either, all pointing to that the eruption is in a more or less stable phase and shows no clear trend, certainly no signs of possibly ending very soon, unfortunately.
Meteorological conditions remain adverse for the western part of the island, in particular the Ariadne valley, where thick vog (volcanic fog) prevails, an unhealthy mixture of gasses and fine ash particles trapped in the air.
In Los Llanos de Ariadne, concentration values of up to 499 grams of fine dust or ash particles per cubic meter in the air have been detected recently. This is 10 times the standard threshold of 50 micrograms/m3 still considered as healthy to breathe. It is strongly advised to avoid going outside, close windows, and wear dust masks (preferably FFP2 type).
