thanks. that was awesome.

I missed two of them the other night. I heard it when I was in another room, but everyone in the chat site said they could see the shockwave when it happened (most said immediately before).

Me: oh wow. smoke/steam whatever coming out from all over the sides.

from someone on the chat:
tops clogged!! big booom coming.

Me:
I just watch five more tiny places start having smoke/steam coming out.
more since I started typing.
weird. scary. like it is going to blow out from everywhere; lots of little cracks or vent forming in the sides. hope not.
ETA: they pulled the camera veiw back to show the whole thing from afar.
ETA2: looks like little streams of lava starting to come out of some of them

multiple streams of lava coming from cone now (not tiny wisps of a stream; pretty fast moving and fairly wide streams. At least two and it looks like a low-shooting vent/opening on top.

Yeah, the lava has been pouring out almost all day (our time).

DK, it is Cumbre Vieja that they have feared would cause the landslide collapse, however, due to the weight of the lava/ash, scientists have been concerned that it could cause a collapse of the volcano, or the landslide either one.

Which scenario they are talking about in that tweet, I don't know at moment.

Interesting tidbits from the chat area on one of the live cameras.

Person was told lots of uplift reported today, that person was trying to verify. been steady at 28, jumped to 36. (still looking to see if the person verified it)

There is a crack in the cone.

Three more areas evacuated tonight. They had already evacuated a whole bunch earlier today.

someone posted that fishermen said there are no fish to be found within 10 km of island. All fish have fled.
Nana note: ^^^^ that right there is a sit up straight moment; fish, like animals, know something is coming.

2.7 EQ a little bit ago

So far, seems the collapse they were talking/worrying about would be a collapse of the cone/volcano.

Said the crack/fault in the island is a good bit away from the eruption/vents.

But what are chances it will create the landslide that will create the tsunami that will flow to the East Coast that will rise up to the 3rd floor levels of Manhattan?

Neither here nor there.
Post #5, big boom at 1:00.

I was thinking this thing will belch & fart for awhile and be done.

Maybe not?

Tambora belched and farted for something like 18 months before it blew it's cap, and then we ended up with the year without a summer... well actually it's probably more like two years. So yes it could do this for awhile and go silent for a hundred years or more, or it could keep building up and shut the global economy down with one massive VEI7 eruption.

Red-hot lava spews from La Palma volcano as eruption intensifies
Updated / Saturday, 25 Sep 2021 13:06

Lava and smoke rise from the Cumbre Vieja volcano on La Palma

Lava and smoke rise from the Cumbre Vieja volcano on La Palma

Rivers of lava raced down the Cumbre Vieja volcano and exploded high into the air overnight on the Spanish island of La Palma as an eruption intensified.

The island's airport was also closed as the volcano entered its most explosive phase so far.

Since it began erupting on Sunday on the small island in the Atlantic, the volcano has spewed out thousands of tons of lava, destroyed hundreds of houses and forced the evacuation of nearly 6,000 people.

Authorities said this morning that the 160 people evacuated from three more towns yesterday would not be able to return to their homes to retrieve their belongings because of the "evolution of the volcanic emergency".

Experts said the volcano had entered a new explosive phase.

"Volcanic surveillance measurements carried out since the beginning of the eruption recorded the highest-energy activity so far during Friday afternoon," emergency services said in a statement yesterday evening.

Spanish airport operator Aena said this morning that the island's airport had been closed.

"The airport is closed because of the accumulation of ash," said the state-owned airport.

"Clean-up operations have begun but the situation can change at any moment," it added.

La Palma, with a population of over 83,000, is one of an archipelago making up the Canary Islands.

According to the European Union's Copernicus Earth Observation Programme, lava has so far destroyed 420 buildings and covered more than 190 hectares of land.

Prime Minister Pedro Sanchez announced La Palma would be declared "a zone affected by a catastrophe" which opens financial aid to residents.

The speed of the lava flowing from the crater has steadily slowed in recent days, and experts hope it will not reach the coast.



If the molten lava pours into the sea, it can generate clouds of toxic gas into the air, also affecting the marine environment.

Yesterday, firefighters retreated from clean-up work in the town of Todoque, airlines cancelled flights, and authorities evacuated the towns of Tajuya, Tacandede Abajo and the part of Tacande de Arriba that had not already been evacuated after a new vent opened up in the flank of the volcano.

Videos shared on social media showed a massive shockwave emanating from the eruption site.

No serious injuries or fatalities have been reported in the volcano's eruption, but about 15% of the island's economically crucial banana crop could be at risk, jeopardising thousands of jobs.

The eruption on La Palma was the first in 50 years.

The last eruption on the island came in 1971 when another part of the same volcanic range - a vent known as Teneguia - erupted on the southern side of the island.

Two decades earlier, the Nambroque vent erupted in 1949.

This is a very different volcano with 9 "mouths" so far, but I gather the main cone just blew sky-high, or rather it did last night. They are telling us the "acid rain" may be here within 48 hours, about 24 hours before it gets to France. No big deal (for us) at last not yet, but something to keep paying attention to. I hope they don't end up evacuating the entire Island but if this thing keeps growing and spreading (as a fisher volcano) they might have to.

The airport on the Spanish island of La Palma was closed on Saturday because of an ash cloud spewing out of a volcano that has been erupting for a week, and scientists said another volcanic vent had opened up, exposing islanders to possible new dangers.

The eruption began on 19 September and has increased in intensity in recent days, prompting the evacuation of three further villages on La Palma. Almost 7,000 people have had to abandon their homes.


The recent volcanic eruption is the first since 1971 on La Palma, which has a population of 85,000 and part of the Canary Islands archipelago off north-west Africa.

La Palma Airport operator Aena said the airport was “inoperative” because of the accumulation of ash. Other airports in the Canary Islands were still operating on Saturday, it adaded, but some airlines were suspending flights.

Emergency crews pulled back from the volcano on Friday as explosions sent molten rock and ash over a wide area. The Canary Islands Volcanology Institute said another vent opened early on Saturday.

Rivers of lava have been sliding down the mountainside toward the south-western coast of the island, destroying everything in their path, including hundreds of homes. However, the speed of the flow had slowed considerably and the lava was now barely moving forward, with about 2 km left to reach the sea, said Miguel Ángel Morcuende, head of the Canary Islands Volcanic Emergency Plan.

“I don’t dare to tell you when it’s going to get there, nor do I dare to make a forecast,” Morcuende told reporters.
A more immediate concern for residents of La Palma is the huge ash cloud rising from the volcano and being carried by the wind to other parts of the island. Volcanic ash can damage people’s airways, lungs and eyes. The local government has urged residents in affected areas to avoid going outside and only do so wearing masks and goggles.

Looks ominous to me, but I get the impression from the tweet, they think it is a good thing.
Guess we will find out in next few days.
ETA; the image is from 6 PM on Sept 24th to around 6 PM on 25th. (I don't know what time zone they are using, probably UTC)

In the last few hours, the amplitude of the volcanic tremor has decreased notably in all the stations of the Canary Islands Seismic Network in La Palma. We recall that the volcanic tremor is related to the intensity of the strombolian explosive activity

Nothing really new this morning that I could find.



LA PALMA, Sept 26 (Reuters) - The airport on the Spanish island of La Palma reopened on Sunday but flights remained cancelled as the volcano continued to spew lava and emit ash clouds over the surrounding area a week after it erupted.
Reuters drone footage showed a rapid river of red hot lava flowing down the slopes of the crater, passing close to homes, and swathes of land and buildings engulfed by a black mass of slower-moving, older lava.

Spain's airport operator Aena (AENA.MC) said the airport had reopened after teams cleared ash off the runway. But Binter, the Canary Island airline saying it will keep flights cancelled today because of the conditions.

"The ash cloud originating from the volcanic eruption makes it necessary to maintain the temporary stoppage of flights to La Palma... The flights scheduled for today have been cancelled," it said in a statement. "The stoppage will continue until conditions improve and allow flying, guaranteeing safety."

Spanish media reported all flights would remain cancelled on Sunday.

The Cumbre Vieja volcano, which began erupting last Sunday, entered a new explosive phase on Friday, experts said. The national Geographical and Mining Institute said on Saturday its drones had shown the volcano's cone had broken.
The eruption has destroyed hundreds of houses and forced the evacuation of nearly 6,000 people since it began on Sept. 19.

"La Palma airport is back in operation. After progress in ash cleaning work, it can now be reopened," Aena tweeted.

Travellers had been faced with cancelled flights on Saturday, and many had joined long queues at the port in the hope of getting a boat off the island. read more
On Sunday, ferry operator Fred Olsen Express said it would add an extra round trip between La Palma and Tenerife from Monday until Wednesday.

"Fred Olsen Express will increase connections... to continue meeting the demand for transport generated by the energency situation caused by the volcanic eruption," it said in a statement.

Some people evacuated from towns close to the volcano were allowed to return to their homes to collect their belongings, authorities said on Saturday night.

La Palma, with a population of over 83,000, is one of an archipelago making up the Canary Islands.

The eruption continues at fluctuating intensity and with significant changes at the morphology of the new crater:
During the course of yesterday, a significant portion of the western flank of the cone collapsed, likely during a series of rockfalls, leaving a narrow horse-show shaped breach, thus lowering the main vent, which continued to produce violent pulsating lava fountains at fluctuating intensity.

During periods, the jets of lava likely surpassed 500 m in height with individual bombs reaching perhaps up to around 1000 m in height. Jets usually were more or less vertical, but sometimes also oblique to the west, suggesting the presence of at least two closely-spaced vents.

The lava flow from the effusive vent on the NW flank of the cone seemed to almost cease during the evening, but later resumed, creating a new flow in the same channel. This lava flow was still active by the time we left the scene at around 10 a.m.

Violent spattering could be seen at the vent; the following video shows the high fluidity of the erupted lava:


Fluctuating intensity of lava fountains
The lava fountaining activity from the main vent changed somewhat as it became more fluctuating after late last night, switching from moderate to very intense during phases lasting several minutes.

After around 0.30 a.m. local time this morning, the fountains significantly decreased and switched to intermittent, weaker pulses. Later, they resumed and gained strength again, but decreased again in the early morning hours, only to pick up again a bit.

The associated ash plume was weaker than during the previous days, but still rose to approx. 3 km height and slowly drifted towards northeasterly directions.

In undisturbed areas around El Paso and Tacande, there is now a 3 cm thick deposit of black ash and lapilli from the ongoing eruption.

Seismic and deformation data
Tremor intensity remains high, but with significant fluctuations over periods of hours. Overall, its trend is either to be stable or even increasing. The latest GPS data suggest that ground deformation is slowing down and coming to a halt, suggesting that the overall magma effusion rate is now in balance with the supply of magma into the shallow reservoir feeding the eruption.

As to what might happen next, there can only be speculation at this point. For sure, it will be interesting...

Canary Island volcano spewing ash again after lull
Updated / Monday, 27 Sep 2021 14:13

People on the coastal areas of San Borondon, Marina Alta and Baja and La Condesa were ordered to lock down

People on the coastal areas of San Borondon, Marina Alta and Baja and La Condesa were ordered to lock down

A volcano began again spewing out ash after a brief lull in the Canary Islands today, where coastal residents are confined to their homes over fears of toxic gases when the lava hits the sea.

La Cumbre Vieja, which straddles a southern ridge in La Palma in the Atlantic archipelago, erupted on 19 September, spewing out rivers of lava which have slowly crept towards the sea.

But this morning, the lava and ash flow had stopped, and the week-long rumble of the eruption faded to silence, before resuming its activity several hours later, an AFP correspondent at the scene said.

Smoke had continued to emerge from the top during the lull.


"In the last hours, the volcanic tremor has almost disappeared, as well as the explosive strombolian activity," tweeted Involcan volcanology institute, using the scientific term for a mix of explosions and lava flow.

"Volcanic activity in La Palma has reduced significantly in the last few hours," Madrid's Institute of Geosciences tweeted.

"We must be very vigilant about how it evolves because the scenario can change quickly."

Several hours later, the volcano started pumping out ash again.



Fits and starts

00183954-614.jpg


Speaking to AFP after the resumption, Involcan spokesman David Calvo said it was "just ash, for the time being". La Cumbre Vieja had been switching between "explosive episodes and lulls for quite a while," he added.

Even so, its activity had "decreased with respect to previous days".

Overnight, the inhabitants of several coastal areas were ordered to stay at home to avoid harm from the release of toxic gases when the lava finally reaches the sea, a process which has been much slower than expected.

Experts say the entry of lava into the seawater will send clouds of toxic gas into the air, causing explosions and a fragmentation of the molten rock like gunshots.

"When the lava, with a temperature of over 1,000 degrees Celsius meets the sea... a thermal shock is produced that generates plumes of water vapour charged with hydrochloric acid," Involcan said.

These plumes "also contain tiny particles of volcanic glass," it said.

"Inhalation or contact with acid gases and liquids can irritate the skin, eyes and respiratory tract, and may cause breathing difficulties, especially in people with pre-existing respiratory diseases."

But Involcan said the vapours were only dangerous to those in the immediate area, with the authorities setting up a two-kilometre exclusion zone to head off curious onlookers.
