What Happens When Volcanic Ash Begins to Fall Globally ?​


Etna ashfall making its way to the Great Lakes in the USA, Pinatubo awakens again, Iceland readies for massive eruption and lumber prices reach all time record high so if you do want to build a greenhouse, its going to cost far more money.



Ash from volcanic eruptions, together with particulates from meteor 'smoke' and wildfire smoke, all jointly contribute to the increased dust-load in the atmosphere. This changes its electric charge rebalancing mechanisms, producing more intense storms and precipitation in the form of record rainfall, hail, lightning strikes, planetary cooling, atmospheric 'anomalies' etc.

Mama Etna does it's thing: Paroxysm No. 14
since 16 Jan 2021

It may not come as a surprize anymore, but the Etna volcano had another short violent eruption, early morning of 17 March 2021. Apparently it started with "Strombolian" style activity (short bursts of relatively low lava fountains) around 01:55 at the "New SE crater". At around 03:25 a lava stream was detected at the surveillance cameras at the Italian INGV, in which the stream went towards the east, into the depression of the "Valle del Bove".
Somewhere around 04:00 private reports from our friends, noted that Etna made very, very loud roars, making them wake up and have difficulties falling back to sleep. (Located north of Catania, around 15-20 km south of the Volcano) Giuseppe, a friend of ours said, he never heard anything like it (so loud). From videos it had a throat kind of roaring sound, constantly ongoing noise, with rhythmic loud booms, reminding me of thunderstorms.


The weather wasn't the best.

A line of Thunderstorms went from the north coast of Sicily around 20:00 and affecting the city of Catania around 22:00 and then went to the southeast, towards the Ionian Sea where they re-ignited at midnight. So, there were quite a lot of clouds left - albeit somewhat clearing up at sunrise. Due to the strong winds, there wasn't much ash detected in satellite images. I managed only to gather low-res images from the eruption.

Etna goes 15th Paroxysm
since 16 Jan 2021

As of writing 10:50 on 19 March 2021, Etna is culminating into another paroxysm, the 15th since 16 Jan 2021. The weather is once again, not really in favor for viewing the show. It is cloudy to overcast along the north and east side of the volcano - and in the areas which appear clear (SE), i only see Cumulus clouds on webcams, without view towards the top of the Volcano. Brief moments on the cam at around 2250 m (7382 ft), did show some of the ash cloud. The Satellite chart also shows the ash cloud this time.

Taal Volcano, Philippines

I often visit the german site "Vulkane.net" by Marc Szeglat - and he mentioned the Taal Volcano yesterday on 18 March 2021, the volcanic institute in the Philippines PHILVOLCS reported that the volcano had numerous earthquakes, and the seismographs recorded 164 signals, from which 94 were of volcanic-tectonic origin, and from those 67 signals being tremors.

My thinking: So, lava is flowing under ground - but that is not always equivalent to that an eruption is guaranteed to occur. Think Iceland: where indeed lava is flowing right now underground the Reykjanes peninsula, in a very long but only 1 meter slim "tunnel") Apparently the tremor on Iceland has steadily decreased as of lately. Taal Volcano on the other hand, has a very explosive history - so any signs there - are not taken lightly.

The Taal volcano shows in the central crater up to 20 meter high fumaroles and a weak inflation recorded, and the sulfur oxide vapors are 605 tonnes a day. THe signs speak for an accumulation of Magma under the volcano.

Breathtaking beautiful image (Taal Volcano Eruption 2020)

Speaking of Taal Volcano - a year ago I stumbled across an image (12 Jan 2020), that took me by storm because of the strange dramatic lighting in the photo - so different than most images I have seen... so I saved it of course, just because of that special atmosphere.

Now, a couple days ago it was reported by the photosite "dPreview" that the very same image is a Nominee for the World Press Awards in the category of "Nature Stories", and therefore more info emerged revolving the photo.

Taal Volcano Eruption by Ezra Acayan (Philippines) for Getty Images

Story: Taal volcano, in Batangas province, on the island of Luzon in the Philippines, began erupting on 12 January, spewing ash up to 14 kilometers into the air. The volcano generated ashfalls and volcanic thunderstorms, forcing evacuations from the surrounding area. The eruption progressed into a magmatic eruption, characterized by a lava fountain with thunder and lightning.

According to the Department of Social Welfare and Development, a total of 212,908 families, nearly 750,000 people, were affected by the eruption. Damage caused to infrastructure and livelihoods, such as farming, fishing and tourism, was put at around US$70 million. Taal volcano is in a large caldera filled by Taal Lake, and is one of the most active volcanoes in the country. It is a ‘complex volcano’, which means it doesn't have one vent or cone but several eruption points that have changed over time.

Taal has had 34 recorded historical eruptions in the past 450 years, most recently in 1977. As with other volcanoes in the Philippines, Taal is part of the Pacific Ring of Fire, a zone of major seismic activity that has one of the world's most active fault lines.


Ezra Acayan also shot beautiful (e.g. reportage style) images from the picturesque MAYON Volcano eruption from Jan 2018 on the Philippines (via the site Aljazeera)

Apparently an eruption is underway in Iceland (picture and link to live webcam below):

"An eruption has begun in Fagradalsfjall. Flight color code is red but very little turbulence is seen on seismometers. The guard's flight will take off soon."
Added: Interestingly a seismologist said just 4 hours before that seismic activity had slowed, and that he believed it meant lava flow into the area was slower and therefore an eruption was less likely:

Here's a picture of how the Fagradalsfjall eruption looks in daylight. It says that activity has slowed:

'The eruption is small and activity has decreased somewhat since yesterday. There are few magma jets and the lava flow covers an area that is at most about 500 meters wide. The eruption is limited to a small area in the valley and it is unlikely that lava flow will cause damage.#Reykjanes#eldgos'

That is pretty close to Spring equinox which happened a few hours ago:

When one goes to the page for quakes, activity is high:

At the same time, there are Global Freedom Demonstrations regarding the Covid measures. Is something burning?

The Eruption

Marc Szeglat from Vulkane.net wrote that the start still came as a surprise because (as I reported earlier) the earthquake rate had gone down during the past week - so all signs pointed towards a relaxation. As the eruption afoot the Fagradalsfjall started on 19 March 2021 at around 20.45 local Islandic time, the tremor levels were very low and no increase had been observed earlier in the frequency bands which were inactive. Even at the start of the eruption, only a very slight raise in the frequency of 0.5-1 Hz was observed. Also the earthquake activity was decreasing.

A vent opened between 500-700 meter, in which several small lava streams emerged. In volcanological terms, this eruption is entirely effusive (meaning, only lava is flowing without explosive appereances or ashfall)

Cool time lapses • Islandic Fagradalsfjall Eruption '21

making the lava movement way easier to follow. Another cool thing to watch (on a larger screen), watching the people swarming out and about, back and forth, right along/outside the lava streams.
