Volcanic activity in Canary Islands 2021

[jand]

The IGN locates 18 earthquakes in the south of La Palma, 4 of them felt
Today at 12:06, due to the increase in height reached by the eruptive cloud, the IGN has issued a new VONA (Volcano Observatory Notice for Aviation) communicating that the current height of the ash cloud is 5000 meters above the level of the sea.


The National Geographic Institute has located a total of 18 earthquakes in the southern part of the island of La Palma, 4 of them felt very weakly by the population .

One of them is located to the west of the island's coast while the rest are located between 10-14 km deep in the area where the reactivation that preceded the eruption of Cumbre Vieja began.

The maximum magnitude is 3.3 (mbLg) corresponding to two of them, indicates the IGN.

Like yesterday, the mean amplitude of volcanic tremor continues very stable in the last 24 hours, in a range of average values ​​with respect to the values ​​observed since the beginning of the eruption.

The island's network of permanent GNSS stations shows a return to deformation stability.

Today at 12:06, due to the increase in height reached by the eruptive cloud, the IGN has issued a new VONA (Volcano Observatory Notice for Aviation) communicating that the current height of the ash cloud is 5000 meters above the level of the sea.

This VONA was sent, as established in the International Civil Aviation protocols, to the VAAC (Volcanic Ash Advisory Center) in Toulouse, the ACC Canarias (Area Control Center), and the AEMET (State Meteorological Agency).

Update from Volcano Discovery and every update I have read today from all countries says there is an uplift and have added maps as proof.

I have no idea why Canarias7 posted ''The island's network of permanent GNSS stations shows a return to deformation stability.''



Since the violent re-start of activity on Monday evening, the eruption has been going on with more or less stable lava output from the vent, and volcanic tremor has been stable. During this morning, a tendency of increasing activity seems to be manifesting itself.
Interestingly, more quakes have started to occur again, mostly at 10-15 km depth under the central part of the volcano. There were 6 quakes of magnitude 3.0 or above and 21 quakes between 2.0 and 3.0. The latest magnitude 3+ quake occurred only 1.5 hours ago, at 11.13 a.m., and was felt again by the local population.
Inflation and ground deformation have picked up as well during the past 12 hours or so, after they had been leveling out in the days before.
What could all this mean? We cannot say for sure, but one possible interpretation could be that the quakes and inflation reflect new magma intruding at depth, from where it might connect to the shallower system and further supply the eruption. It could also lead up to new vents forming, depending on how effective the currently active magma feeding system is to counteract the building pressure underground.
The next days will likely be very interesting to follow!

''30/09/2021 h Canary Islands.- PALM ISLAND ERUPTION.- GASES, MORE ASHES AND RAIN OF PYROCLASTES. THE DANGER OF GASES, ASH AND PYROCLASTES IN HEALTH.- Gas emission control is very important, especially sulfur like SO2, SO3 and H2S and any volcano that is precious is put on an alert page for this gas by satellite measures and on land, giving alerts, but, this is Spain and here of course nothing at all. There's a satellite page to watch from NASA

And also from the Copernicus system from late afternoon let out something, system that has caped and releases data from the extension of laundry 24 h delay... I ignore the reasons. I leave you two very good examples.. Iceland and Hawaii.

Sulphur gases such as SO2 or H2S (smell of rotten eggs) are dangerous in certain high concentrations as it causes health problems in people, so don't take it as a joke. If you smell so much like rotten eggs in a place with a lot of concentration, so that at 2-3 minutes they no longer smell it, because they saturate the olfactory recipients of your nose, leave that area and look for a closed place inside from home. If they smell it... nonstop, it's very annoying, but indicates low concentrations, usually not too dangerous.

GASES TO BE TOUCHED
1-Thus the SO2 that has ′′ sulfur smell ′′ causes the following effects: Difficulty in breathing. Inflammation and irritation of the airway. Eye irritation from sulfurous acid formation over wet mucouses.

2.- H2S or sulfhydric acid or ′′ smell of rotten eggs ′′ irritates soft tissues of the body, like eyes, nose, throat and lungs. High concentrations quickly dampen sense of smell and continuous exposure can lead to asthma attacks, respiratory distress, loss of consciousness and death.

3.- CO2 can displace oxygen in low-lying areas, basements and poorly ventilated depressions, including coastal areas, may cause respiratory problems and even death if you are too long in the area where no oxygen is.

And there's more... like HCL or HF in areas close to mouths or when lava laundry interacts with masses of salt water as is now the case with the ocean. Here's a complete guide to the issue:

VAAC Toulouse's new prediction of ash cloud evolution reaching 5000 meters high and for SO2 for today in La Palma. The wind should move it west of the island and leave ashy free from both the airport area and approach. In the valley of Aridane to N and NO of the eruption you smell quite like Rotten eggs and ashes and pyroclasts fall over the area.

And a long time ago article that talks about what's to come, and we only remember Santa Barbara when Thunder. (Enrique)

Cont:

They tell me that they are evacuating the commercial area of the cat alley north of flow, they must fear a broken tear of the lavic canal or not discard that has already occurred and will drop a flow on the N edge of the existing one. I leave you a drone flight today.. (Enrique)

There has been a 3.5 Fuencaliente felt over most of the island.
