Welcome to a new Friday feature on Volcanocafe.
Starting today and coming every Friday, we will be publishing a report on the previous weeks volcanic eruptions from around the world and also any noteworthy stories that also pop up on Twitter or in the news. I will also be posting a globe with the volcano in question marked so that people who are not familiar with them can get an idea of their location.
As this is the first edition of the report, and we are already into February, I thought a recap on January’s activity, based mainly on what was reported by the various VAACs (Volcanic Ash Advisory Centre) around the world, which some extra information thrown in if I could find it.
London VAAC have no reports of activity from 01/01/2016 to 31/01/16
Toulouse VAAC have no reports of activity from 01/01/2016 to 31/01/16
Anchorage VAAC have no reports of activity from 01/01/2016 to 31/01/16, however they do point to some activity from Zhupanovsky, which is covered by the Tokyo VAAC
Washington VAAC has a number of activity reports:
- Santa Maria, Guatemala has had a number of reported activities over the period, mostly low level and minor ash emissions.
- San Miguel, El Salvador had a couple of days activity in the middle of the month with a “moderate ash eruption… reaching 1500 meters” (according to Volcano Discovery)
- Reventador, Ecuador had a few events of low level ash emissions with lechaudrondevulcain.com reporting “At night, small emissions up to 150 m above the summit of the volcano were observed, such as a glow on the western flank to about 1200m below the summit.” on the 29th of January.
- Popocatapetl, Mexico had a busy month with reports throughout the month. Explosions and plumes were reported during the month and Volcano Discovery reports that a “growing lava dome has filled inner crater” and this is responsible for the glow visible on the night time webcam shots.
- Momotombo, Nicaragua has had a couple of very impressive eruptions this month. On the 3rd we had a very impressive night time explosion which covered the volcano with glowing material. This was followed on the 12th with another large blast which sent a plume up to 3km and sent a pyroclastic flow down the side of the volcano
- Fuego, Guatemala is another volcano that had impressive eruptions. At the start of the month, Fuego had a beautiful eruption with lava fountains and flows lighting up the night sky and a plume that reached 24,000 feet (7km). An eruption on the 21st that caused La Aurora airport to close with a plume that reached a similar level as earlier in the month.
- Colima, Mexico was a very busy volcano throughout January with multiple events throughout the month. However, the story of the month from this volcano appears to be the sighting of a “UFO” that used the eruption to either “refuel” or “transported someone or something to or from the underground base below the volcano” according to the Daily Mail.
Montreal VAAC have no reports of activity from 01/01/2016 to 31/01/16
Wellington VAAC have no reports of activity from 01/01/2016 to 31/01/16
Tokyo VAAC has a number of reports:
- Karymsky Volcano in Russia provided a number of explosions throughout January providing plumes up to 22,000 feet (7km).
- Sheveluch is another Kamcatcha volcano that provided a number of large plumes, with KVERT reporting a plume to 22,000 feet (7km) on January 9th and warning that “Ash explosions up to 32,800 ft (10 km) a.s.l. could occur at any time”
- Zhupanovsky also provided a number of explosive events, throwing a plume up to 26,000 feet (8km) on the 19th, 21st and 24th of January.
- Japan’s own volcanoes appear to have been quiet throughout January with only Suwanosejima providing any activity that the Tokyo VAAC reported, and even this was only to 5000 feet (1.5km)
- Japan’s coastguard announced that the Nishino-shima eruption is officially over, following fly-overs in December and January, which showed no on-going activity.
Buenos Aires VAAC
- Capohue was active throughout the month with almost continuous steam emissions and some low level ash eruptions.
- Nevados del Chillian had a short burst of activity on the 8th and 9th of January (according to the Smithsonian Institute, but not listed on the VAAC reports), with at least 1 phreatic event causing an ash emission. And a further “puff of steam and gases to FL120 (12,000 feet or 3.6km) on the 16th/17th of January (according the the VAAC report)
- Sabancaya had various unconfirmed reports from pilots of volcanic ash, these appear to have been largely discounted.
- Ubinas had an explosion on the 15th January which sent a plume up to 10,000 feet (3km)
Darwin VAAC archive is a bit of a mess, there are no labels or information regarding the volcanoes that it covers, just a bank of text files with dates, so apologies if I miss anything.
- Sinabung continued to do what it has done for the last few years with numerous pyroclastic flows and ash clouds produced.
- Dukono was also a very active volcano throughout January sending numerous ash clouds up to 10,000 feet (3km)
- Tengger Caldera managed to produce a number of ash events up to 14,000 feet (4km) and during to 20-26th “Seismicity fluctuated; the number of explosion signals increased and some shallow and deep volcanic earthquakes were recorded” (according to the Smithsonian GVP page)
- Barren Island managed to produce a couple of low ash events, with plumes sent up to 5,000 feet (1.5km) at the beginning of January
- Soputan managed to produce a lava flow which was seen on the east flank on the 4th of January (Smithsonian) and a pyroclastic flow on the 6th of January. Ash plumes were also sent up to 6.5km high and ashfall was reported in villages up to 14km away.
So that was quick run down of the eruptive activity around the world for January. I apologies that it was a bit dry, but it was a lot of info to dig through and I hope that once I get into the swing of the weekly reviews, that things will become less dense and I can perhaps do a bit more information regarding the activity.
So I guess this is a good place to start with February and my first Weekly Report (even though it’s slightly less than a week.)
February 1st 2016
- Australia’s Big Ben volcano on Heard Island managed to be filmed during an eruption by scientists. Normally any activity from this remote location is only noticed on satellite imagery. A video of this eruption can be found on the BBC.
- KVERT reports that Karymsky send a plume of ash up to almost 10,000 feet (3km) and in typical fashion The Express reported on “Fears of the Big One”
February 2nd 2016
- Turriabla, Costa Rica recorded a “passive eruption of gas and ash” according to El Economista, which reached 1,600 feet (500m)
February 3rd 2016
- Popacatapetl, Mexico according to CENAPRED, El Popo had “17 low-intensity exhalations and 9 explosions”, CENAPRED also are warning people to stay away from the volcano due to the danger of “ballistic fragments”.
Colima continued her on-going activity with several explosions.

Our friends at VolcanoHotspot tweeted this stunning picture

#VolcánNevadosDeChillán. Yellow alert continues. Seismicity focused as seen in the graph. 4-2-2016
February 5th 2016
Sakurijima burst into life this morning with an explosion which a vulcanologist that viewed the footage described as “average”
Thanks to wasgeht for posting a youtube video of the explosion:
This eruption broke pretty late on for this post, so more next week!!
