Moderate Explosion Of The #Popocatepetl #Volcano.
From Matías Tlalancaleca-Puebla
At 2:16 am an explosion of #Popocatépetl was recorded. It was heard in nearby towns and even in Puebla where doors and windows were shaken by the shockwave.
Although clouds covered the volcano, you can see the glow and seismic record.

Villarrica volcano (Central Chile): strombolian activity remains elevated
The activity at the volcano continues to be elevated.
An increased strombolian-type explosion took place from the summit vent over the last night with glowing ejecta thrown at an approximate distance of 400 meters off the crater.
The Volcanic Alert Level remains at Yellow with 500 meters exclusion zone around the main crater in place.

Enmedio Volcano, Canary Islands
In order to connect to the earthquake swarm between islands of Tenerife and Gran Canaria today/yesterday, i found more information about the submarine volcano Enmedio, whose text is also coming from the site Vulkane.net - which writes following:
Unterwasservulkan Enmedio bei den Kanarischen Inseln
Enmedio ist ein Unterwasservulkan der zwischen den Kanarischen Inseln Teneriffa und Gran Kanaria liegt.

Erta Alé, Ethiopia
28 Jan 2023
An eruption has occurred at the Erta Alé Volcano in Ethiopia.
Photos by Ayuba Ahmed • 28 Jan 2023
German Vulkane.net reported following in their latest article:
Rupture in the north crater of Erta Alé volcano confirmed
This morning I reported on the unusually high heat radiation emanating from the Ethiopian volcano Erta Alé and presented 3 scenarios, of which scenario b) has now been confirmed. This was confirmed twice: first, a new Sentinel satellite image was published, which shows in the infrared spectrum that the heat radiation emanates from the North Crater, whose entire floor radiates heat. Then came the second confirmation in the form of photos shared in our FB group. Lava can be seen gushing from a new vent on the crater floor. A low hornito has already formed around the vent. The rate of production must have been relatively high, especially at the beginning of the eruption, because the flat crater floor was quickly flooded with lava and filled up by several metres. The eruption is reminiscent of the eruption in Halema'uma'u crater in Hawaii.
It is very likely that this lava lake is still a secondary or dammed lava lake that does not yet have circulation, but it is not impossible that a second permanent lava lake will develop from this. But it is more likely that it will remain a dammed lava lake. As you can see from the photos, the crater rim is not very high. I would estimate it at 15 m. If the activity lasts several days, the crater could fill up and the lava could overflow. It is then quite possible that it will flow towards the south crater and fill it up further.
The only thing missing now is that other volcanoes in the Afar Triangle will also erupt. Erta Alé is only one of several shield volcanoes in the region. The whole structure reminds me a little of a mid-ocean ridge, a comparison that is not quite as far-fetched as it might seem at first glance: in the Afar Triangle, the divergent East African Rift Valley opens up to the Red Sea. Only a higher sill separates the sea from the rift. During my first stay in the region, I found corals that testify to the fact that the Afar Triangle had already been flooded by the sea.

East Epi, Vanuatu
31 Jan 2023
Also German Vulkane.net had an article about the underwater volcano located east of the island of Epi in Vanuatu. Here is the report:
East Epi underwater volcano erupts off the east coast of Epi
A few hours ago, the East Epi underwater volcano erupted in the South Sea archipelago of Vanuatu. It is located about 7 kilometres off the east coast of Epi Island. Images show the ash vapour cloud of a Surtseyan eruption rising several hundred metres high. WAAC Wellington issued a VONA warning at 6.30pm Zulu time last night but was unable to satellite the eruption cloud. The message states that the eruption cloud has already disappeared. However, this does not necessarily mean that the eruption is already over. It could also be the prelude to a longer-lasting volcanic eruption.
No signs of an imminent underwater eruption have been reported. The last Sentinel satellite photo was taken on 30 January, one day before the eruption. Water discolouration is not visible there. However, there was a strong earthquake Mw 7.0 on 08 January on the island of Espiritu Santo, 200 km away. It is not impossible that the quake triggered the volcanic eruption.
The underwater volcano is not only located off the east coast of Epi, but also at the same time about 14 km off the south coast of Lopevi. This volcano has been showing signs of an imminent eruption for some time and has been set to warning level "2" by the VGO. In their weekly bulletin on Lopevi, they write of great volcanic unrest with steam emissions and volcanically induced earthquakes.
(Above) Seismogram at Ambrym Volcano [I think]
It is also interesting to note that the summit of the Ambrym caldera is only about 50 km from the submarine volcano. Ambrym is known for its lava lakes in the Marum, Benbow and Niri Mbwelesu craters, which were last permanently active in 2018. In March last year, it briefly looked as if the volcano would reawaken, but it did not make it to a prolonged eruption. The day before yesterday, I saw a series of seismic signals on the seismogram to Ambrym and thought "whoops, something's happening". Today you see similar signals and at a time when the submarine eruption was happening. It is quite possible that the vibrations from the eruption reached the seismometers on Ambrym.
Tsunami warning
The Fiji Seismological Institute issued a tsunami warning because of the submarine eruption. A particularly great danger is posed not only by powerful explosions whose pressure waves could trigger tsunamis, but especially by submarine landslide events should the volcanic edifice destabilise.

Etna, Sicily
1 Feb 2023
More about Etna, which has been active with lava streams for many weeks now. Beautiful images made by "Etna Walk", and the article comes from German Vulkane.net, which wrote following (below images).
Lava flow on Etna remains active
The lava flow on Etna is still active, but its intensity fluctuates significantly. Yesterday at noon, hardly any thermal signal could be seen on the livecam, but the lava output increased again in the afternoon, so that the INGV issued a new activity warning. On the whole, however, the activity has remained as we know it from the last few weeks: Lava flows from a vent at 2830 m altitude and reaches the steep slope of the Valle del Bove in spurts. In the best winter weather, the red lava contrasts with the white snow, creating very atmospheric night shots.
Data on the Etna eruption
The analysis of satellite data shows the INGV scientists that the production rate reached a maximum value of 1.9 cubic metres per second on 30 January. A total of about 5,990,000 cubic metres of lava had been produced by this date.
[Now that sounds a lot in numbers, but putting the number in a converter, in order to see how this relates to km3 instead; the result i got was "only" 0.00599 Cubic kilometers (km3)]
Between 28 November 2022 and 29 January 2023, so much lava was produced that it covered an area of 0.93 square kilometres. The longest lava flow was 1920 metres long.
The INGV's new weekly bulletin also attests to the volcano's weak infrasound activity and sporadic ash eruptions from the New Southeast Crater. There, red-hot vents and thermal anomalies at fumaroles were detected in some places.
The tremor was at a medium level during the observation period 23-29 January. The tremor source was located in a region between 2400 and 2800 metres above sea level and lies below the base of the southeast crater cone. The tremor originates from the magma body feeding the lava flow. It probably intruded in spring 2022, a few weeks before the first lava flow erupted. The intrusion was accompanied by a swarm quake. This was also the last major swarm earthquake on Etna since then. No significant ground deformation was observed during the observation period. However, there is always a weak inflow of magma that is reflected in long-term inflation and weak ground uplift.

Here's a current map of ongoing volcanic eruptions. I thought it would be interesting to see the global pattern of these eruptions considering ongoing reports. Daily (static) map of currently erupting active volcanoes world-wide
