Astonishing images were taken - especially the first photo - showing the ambiance of the whole eruption together with the houses everywhere close by. Fascinating as well scary at the same time. Really speechless.

The volcano is called Semisopochnoi. From Express.co.uk:

It is located on Unyak Island, which is part of the Rat Islands group in the western Aleutian Islands of Alaska.

A RED alert warning has been issued by scientists stating that a "major eruption" of an Alaskan volcano is occuring.​

Volcanologists have stated that the major volcanic eruption is underway with hazardous activity both on the ground and in the air. Seismic observations represent an increase in eruptive activity at the site of the volcano. Scientists have upgraded the Aviation Color Code and Volcano Alert level to a red warning.

The volcano is called Semisopochnoi. It is located on Unyak Island, which is part of the Rat Islands group in the western Aleutian Islands of Alaska.

Observations of Semisopochnoi volcano shows an increase in ash plumes rising to 15,000 feet into the atmosphere.

The ash emissions from the volcano have increased in frequency and intensity and can be seen on satellite images rising above the weather clouds.

The ash cloud, blown by high winds, has extended approximately 60 miles to the southeast of the volcano.

Alaska Volcano Observatory (AVO) reported: "Explosions have been observed throughout the day and increased sulfur dioxide gas emissions have been observed in satellite data this afternoon.

"These observations represent an increase in eruptive activity and Aviation Color Code and Volcano Alert level are being increased to a red warning.

"Increasing high clouds over Semisopochnoi will likely obscure satellite views of ash emissions within the hour.

"Seismic and infrasound monitoring will continue to provide notice of ongoing explosive activity, however, it cannot determine the height or extent of ash emissions.

"The Alaska Volcano Observatory will continue to closely monitor all available data."

The volcano sits on the Ring of Fire that surrounds the Pacific ocean.

Cumbre Vieja Volcano, LaPalma - Spain

20 Sep 2021

I just got know, that the cousin of my husbands ex wife, apparently lives 5 km from the eruption site on LaPalma - albeit on the other site of the Cumbre Vieja Volcano ridge - so his family seems is fine. He hasn't gotten back with much info yet. Apparently the airport, also located on the other site, has reopened again. He is a guy who has worked for 20 years at the Roque de los Muchachos Observatory at the Italian Galileo National Telescope. :wow: Waddayaknow.

Marc Szeglat reports via his german site Vulkane.net following:


Day & Evening:

The volcano at Cumbre Vieja on La Palma is still active. Yesterday afternoon, 2 fissures had opened, each about 200 m long. They run in a line and can actually be seen as one 400 m long fissure interrupted in one piece. Lava fountains rose several hundred metres high. The VAAC detected volcanic ash at 3000 metres. As is often the case with fissure eruptions, many of the vents along the fissure have already ceased their activity. However, recent video footage still shows a wide lava fountain rising. One vent has been strombolically active this morning.

A wide lava flow has marched right through the settlement of El Paraiso, burying about 100 houses. It is an Aa lava flow that is several metres thick. It initially travelled up to 700 m per hour. The lava has an exit temperature of 1075 degrees. This means that the lava is much cooler than at Fagradalsfjall on Iceland. MIROVA registered a very high thermal radiation of 2828 MW power tonight.

Paradoxically, many news reports say that the eruption is taking place in a non- or sparsely populated area. :scared: The pictures and facts speak a different language. Only a few volcanic slopes are more densely populated than is the case here. However, the houses on the flank seem to be mostly holiday homes. Nevertheless, 5000 people are being evacuated. The evacuations are hampered by onlookers blocking the roads.


from this morning

the whole area is shrouded in haze, partly caused by volcanic gas, but also by the numerous fires. INVOLCAN volcanologists put the sulphur dioxide emission at 6000-9000 tonnes a day. The visibility of the eruption is very limited, but I have the impression that it is decreasing. Seismicity has greatly diminished and only a few tremors have been recorded in the last few hours: either new magma is no longer rising, or the paths of ascent are clear. Since the ground deformation is now 16 cm, the latter is probably the case. However, the curves of the GPS measuring stations are starting to drop: more lava is erupting than magma is flowing in. Below is a livestream from local television.

Here some more images from La Palma. Houses falling under the lava. They say that the lava will continue for months. Also that when she will reach the ocean it is danger of explosions in the ocean.

More than 5 thousand people are out of their houses or villages waiting. The government give the assurance that they will help to the reconstruction. But they lie.

It is a tragedy and our President, the psychopath president of the Canarias Island, said: enjoy this marvelous spectacle of the nature.

Also in the second video you can see handsome police man helping to save some animals.

Etna Volcano, Sicily - South Italy
Paroxysm No 55 (since 16 Feb 2021)
21 Sep 2021


Mama Etna isn't standing in the shadow of the European Volcano scene... :-P and just blew another Paroxysm, the 55th, in a row of many since 16 Feb 2021.

writes at his site 🇩🇪 Vulkane.net today following:


Cumbre Vieja continues

"The eruption at Cumbre Vieja on La Palma remains stable and continues without much fluctuation. A lava fountain is being produced which feeds lava flows. There are occasional strombolian eruptions from a 2nd vent. A 3rd vent is effusive. Last night, a stronger explosion was observed, spherically dispersing incandescent tephra. Such explosions are known from Etna, among other places. There they mainly occur during the final phase of paroxysms. They have already been described as phreatomagmatic.

The lava flow crosses the municipality of Todoque and is close to a cinder cone on the coast. This blocks the path to the sea and must be flowed around. The latest forecasts say that Ocean Entry could then occur the next night. However, this "event" has already been postponed several times because the progress of the lava front on the flatter terrain in the coastal area has slowed down. If Ocean Entry does occur, it could be a spectacular event as it is a cliff face.

Since yesterday afternoon the seismicity has decreased and only single earthquakes were recorded. On the other hand, the tremor increased significantly, which caused additional concern. There was speculation about whether the volcano might be entering a more explosive eruption phase. New data from volcanologists is still pending and will be provided in an update"

28 cm inflation

I also read at the Spanish Institut Geográfico Nacional, that the accumulated inflation has now reached 28 cm - which means a lot of magma is collecting under the volcano...
Additionally I encountered some magnificent photos people have made from the eruption, between 20-22 Sep 2021 + one photo from 19 Sep 2021, how it all started.

Canary Islands island/Spain: A volcano erupted on the Spanish Canary Island of La Palma on Sunday, sending lava shooting into the air and streaming in rivers towards houses in two villages from the Cumbre Vieja national park in the south of the island.
Incidentally, we owe the term "caldera" to the Canary Islands.The Wiki on La Palma has:
In 1815, the German geologist Leopold von Buch visited the Canary Islands. It was as a result of his visit to Tenerife, where he visited the Las Cañadas caldera, and then later to La Palma, where he visited the Taburiente caldera, that the Spanish word for cauldron or large cooking pot – "caldera" – was introduced into the geological vocabulary. In the center of the island is the Caldera de Taburiente National Park; one of four national parks in the Canary Islands.
La Palma.png
On the map above, the larger island next to La Palma is Tenerife, followed by the round Grand Canaria

History of the eruptions on La Palma:
Since the Spanish have kept records, there have been eight eruptions – all of which have occurred on the Cumbre Vieja:

  • 1470–1492 Montaña Quemada
  • 1585 Tajuya near El Paso
  • 1646 Volcán San Martin
  • 1677 Volcán San Antonio
  • 1712 El Charco
  • 1949 Volcán Nambroque at the Duraznero, Hoyo Negro and Llano del Banco vents
  • 1971 Volcán Teneguía
  • 2021 Volcán Cabeza de Vaca (ongoing)
So it is exactly 50 years since the last time.
