Welcome to another Friday Update!
This week also concludes the first month’s reporting. I hope everyone is enjoying the series so far!
I have enjoyed been heartened greatly by everyone’s comments. I was unsure how the series was going to be received by everyone and It appears that this apprehension was unfounded.
I have enjoyed reading the reports and have started to get into a rhythm in terms of taking notes through the week and writing them into a fuller piece in time for publication.
This week sees a very slight change in how I have approached the formatting of the post. Instead of going by region, The volcanoes are sorted by the reporting VAAC, with the VAAC in question linked at the beginning of that section. This is then followed by the volcano name in bold text and the Google Globe showing it’s location and then a brief summary of the activity and then finally any images or social media posts that I find that useful.
I’d love to hear everyone’s comments on this slight change and I welcome any suggestions as to any other changes you’d like to see.
Heading to the Washington VAAC area:
Colima continues its recent activity with occasional bursts of activity throwing plumes into the air
In Equador, the Cotopaxi volcano was reported by a MWO (Meteorological Watch Office) observer to have erupted on the 27th sending a plume of ash to an estimated 20000 feet, however I was unable to corroborate this with any further information from other sources. Even the report states that the plume is not observed from satellite data.
Fuego continues it recent activity with occasional bursts of ash and a visible hotspot visible at night in the crater.
Washington VAAC is only reporting light emissions and these plumes are up around 10000 feet in height. However as you will see below, there have been some large explosions heard at a 40 km distance from the volcano and shockwaves felt even further away at 70km.
Nevado del Ruiz
An MWO observer pilot from Bogata reported activity on Ruiz on the 26th with ash reported to 20000 and INGEOMAS (Instituto Colombiano de Geología y Minería) reported ash continuing on the 29th February and the 1st of March. A further report suggests a further eruption on the 3rd with ash reported to 30000 feet via ASHTAM (for further information about ASHTAMs)
Washington VAAC suggests that a MWO pilot reported an ash emission occurred at Reventador on the 2nd March, but I was unable to get further information.
Satellite observations show that ash was observed on the 27th and 29th to 13000 feet and 14000 feet respectively
Ecuador’s Tungurahua volcano has had a very active week with large plumes virtually every day. The 26th of February saw a large plume reportedly sent up to 44000 feet and continuing emissions to 24000. This set the tone for the rest of the week with the emissions continuing to be above 20000 on everyday except the 27th when they reached 28000 feet.
There was no report of activity from Masaya, but I had to share this video that appeared on my Facebook stream 😀
Heading to Asia, first on my list is Dukono, which has been continuously producing ash to around 8000 feet everyday this week.
Sinabung is another of the Asian volcanoes with continuous activity this week. CVGHM (Center for Volcanology and Geological Hazard Mitigation) report eruptions everyday, noramlly to around 12-14000 feet, these normally are accompanied by pyroclastic flows down the valley below.
Papua New Guinea’s Bagana volcano produces plumes on the 2nd and 3rd of March which were picked up by the Himawari-8 satellite. These plume reached the height of 7000 feet.
The Himawari-8 satellite and the JMA (Japan Meteorological Agency) reported an eruption to 7000 from the Suwanosejima volcano in the southern Japanese islands.
Sakurijima continued its recent explosive activity with daily blasts sending ash plumes up to 11000 feet on the 27th and 28th February. The @en_sakurajima twitter account has not tweeted this last week so our running total of the number of events this year is stopped for the moment.
The JMA reports an eruption of Asosan on the 3rd of March sending a plume to 8000
A new eruption of Alaid was reported on the 3rd of March sending a plume to 11000.
Karymsky was reported to have had eruptions sending plumes to 17000 feet on the 36th February and the 1st March. KVERT reports a thermal anomaly over the volcano and fresh deposits of ash in the immediate area.
Sheveluch is another Kamcatcha volcano continuing to send plumes into the sky with one event on the 28th reaching 20000 feet and producing a pyroclastic flow (see below)
Buenos Aires VAAC reports “light VA (Volcanic Ash) and steam” continuing to emit from Copahue.
This concludes this weeks report.
Have I missed anything??? Let me know in the comments 😀
