Volcano in the Canaries: a cloud laden with sulfur dioxide arrives in France

2021-09-23T21:47:29.237Z


It will be particularly present on Saturday, but with limited health risk, although more acid rain than usual is expected.


The eruption of Cumbre Vieja in the Canary Islands continues and is not without consequences in the northern hemisphere.

A cloud charged, among other things, with sulfur dioxide, has formed over the archipelago and is rising towards Europe, passing through northwest Africa and the Maghreb.

If the virulence of the eruption has diminished, the volcano continues to emit smoke in quantity and to supply the air with different substances.

They can have an influence on health, but which would be minimal, even very weak.

The volcanic eruption continues in La Palma (Canary Islands) 🌋 The lava flows have slowed down, but the sulfur cloud plume is still present, although limited: it is a lateral eruptive mouth that had formed on the slopes of the main volcano.

According to the Canary Islands Volcanological Institute (Involcan), the eruption of Cumbre Vieja could last “between 24 and 84 days”, with significant gas and smoke emissions over this period. According to the Involcan, between 6,000 and 11,500 tonnes of sulfur dioxide (SO2) are spit out into the atmosphere daily, according to data cited by AFP. The cloud, which has already reached the Moroccan coasts and the Iberian Peninsula, should then rise towards the Balearic Islands and the south of France, according to projections by the European program Copernicus. According to the same source, this cloud of sulfur dioxide should even cover the entire western Mediterranean and much of the Maghreb on Friday.

It will go up to France on Friday and especially Saturday, arriving via the Pyrenees and the Mediterranean.

The south and east of the country will be the most affected until the gradual evacuation of this cloud on Sunday.

As Keraunos, the French observatory for tornadoes and severe thunderstorms, points out, the densest concentration of particles should be at an altitude of between 1000m and 3000m.

The SO2 concentrations from the eruption of the volcano in the #Canaries will increase over the Mediterranean basin and in France during the weekend, under the effect of a southwest flow.


They will be especially sensitive between 1000 and 3000 m altitude.

The particular problem that arises is that thunderstorms are expected Saturday over a large part of the country.

They are therefore likely to bring these SO2 particles to the ground.

BFMTV explains that the rains "will be a little more acidic than usual".

The distance separating the Canaries from mainland Europe allows SO2 particles to be partially diluted.

The phenomenon expected this weekend will remain "quite weak in France because it is still well dispersed", according to Christophe Person, the meteorological specialist of the channel.

A specialist in the Copernicus program agrees with this.

"The impacts of SO2 on weather conditions and surface air quality are probably very low."
