Albert casting a line in Yellowstone yesterday, trying to catch some whoppers! – taken from here
Welcome to another (late) weekly update. I am sure everyone will agree that yesterday’s big news from Yellowstone deserved a day to be digested.
In case anyone did not realize (and many did not), yesterday was April Fool’s day and Albert served up a cracker of a story for everyone, which some (especially on Facebook), fell for hook, line and sinker.
I have blurred the names and profile pictures of the following comments to save the blushes of those involved:
I am sure there are more comments hidden around the various Facebook shares of the article too.
Starting with the quiet VAACs, London, Wellington and Montreal are the only quiet areas this week, although Montreal did have reports of ash from Pavlof, but this will be covered under the Anchorage reports.
Etna ended the week with a couple of small eruptions. On the 31st, a small ash eruption was reported to 10000 feet, and on the 1st a similar report of ash to 15000 feet.
As Carl said in his article last week, Pavlof had a Hekla moment erupting without any warning and catching everyone by surprise. An initial report by a pilot on the 28th of an eruption caused a VAA to be issued at 0100 UTC, this report showed a eruption of ash to 20000 feet, further reports throughout the day increased this height to 30000 feet, then 37000 and finally 40000 feet where it appears to have stayed steady until 0302 UTC on the 29th, when the report suggested that the plume had dropped in intensity to 25000 feet.
The Event finally ended with a report on the 30th the 1021 UTC .
Colima has had a busy week continuing it’s recent trend of short lived explosions of ash. The VAAC reports show that ash was sent up to around 17000 to 18000 feet mark, with a plume to 20000 feet reported on the 29th of March.
A single event was reported at Cotopaxi on the 30th when a plume was reported up to 20000 feet.
Another volcano reported with a single event is Fuego. On the 27th ash was reported up to 20000 feet, this appears to be a continuation of the previous day’s report (as reported last week)
Returning to a busier state this week is El Popo. Daily activity was reported throughout the week with plumes ranging from 21000 feet all the way up to 30000 feet and incandescence reported visible on the webcams on the 28th.

At Reventador, a “possible” ash emission was reported on the 31st to 30000 feet, no further information was available regarding source of this report, but given previous weeks reports I will assume this come from the local MWO.
on the 29th, a “blip” on the seismographs suggested an eruption once more at Nevado Del Ruiz but due to bad weather and cloud cover, this was not visible on satellite nor webcam footage. However on the 30th, a plume was reported and corroborated to 30000 feet.
The local Meteorological Watch Office reported a continuation to last weeks eruptions with ash reported to 25000 feet on the 27th and a further eruption reported on the 28th, however no further data was given for this particular event.
A brief return into the report with a single event for Santa Maria de Guatemala with ash reported to 17000 feet on the 29th of March.
A possible new eruption was reported on the 31st from Tungurahua, with the seismograph suggesting some activity but the visible sources were unable to corroborate due to cloud cover.
Dukono continues to produce a steady plume to 7000 feet every day.
Sinabung also continues with her recent trend in activity with eruptions and pyroclastic flows reported throughout the week, with plumes reaching 11000-14000 feet mark.
Quietly sneaking into this weeks report is Indonesia’s largest volcano, Mount Kerinci. Reports from CVGHM show that starting on the 30th and continuing on the 31st and 1st, Kerinci sent ash up to 16000 feet.
A short single report from the 1st shows an event on the 1st of April throwing ash up to 10000 feet.
Switching VAACs, we find that the Kuril Island volcano of Alaid continues its recent activity, with “possible” eruptions reported on the 30th and 31st of March sending ash to 10000 feet.
Slightly further sound than her sister volcano of Alaid, sits Chirkurachki in the Kuril Islands. Starting on the 29th and continuing on the 30th and 31st Chirkurachki sent plumes up to a similar level as her sister. you can see how close these two volcanoes are in CultureVolcan’s tweet above.
On the 29th in the Philippines, a report from Phivolcs and the Himawari-8 satellite picked up an eruption of material to 10000 feet.
March ended on a spectacular note for Sakurajima. A large explosion was reported on the 26th sending ash up to 9000 feet, followed by a more usual 5000 to 8000 feet eruptions on the 27th and 28th. Then on the 31st we had a bigger explosion than has been recently reported sending ash up to 10000 feet, it appears that against its pattern normal short lived plumes, this event continued into the 1st of April with “continuous” ash reported and further larger explosions raising this ash to 14000 and 15000 feet.
Heading back to Russia, Sheveluch has had a number of events over the past week. Starting on the 28th we had reports of 3 seperate events sending ash up to 14000, 12000 and 13000 feet. The volcano the had a rest on the 29th, before bursting back into life on the 30th with a plume to 14000 feet, 20000 feet on the 31st, before dropping back down to 14000 feet on the 1st of April.
Rounding up to Tokyo reports is a single report of activity on the 30th from Suwanosejima, with an eruption reported to send a plume to 6000 feet.
Finally rounding off our report is a report of activity at Sabacaya, where a pilot sent in a report of ash, but webcam feed and satellite data appear inconclusive. No other data on potential ash levels.
I will finish off this weeks round up by asking a question of the readers.
In a conversation between Carl, Henrik and myself, Carl and Henrik suggested that they have a problem with current format causing the comments box to jump around and generally have a fit when their computers load the page.
Personally, I dont have this issue, but I suspect that it is due to me having all the images and links in my cache and therefore loading quicker. I also suspect that because most of the images are hosted on Twitter and Facebook, there maybe a delay in the cross-loading from these servers.
So to my question, is this an issue for everyone?
If this is a problem, I will make changes to the setup so that I am not posting a direct link to the content, instead I will grab a screenshot of the tweets and posts and provide a link to the source. I will also look into other options because I will freely admit doing it the current way is very simple and changing to a screenshot/link setup will significantly add to the time this take to write. It may seem fairly easy, but this is actually very time consuming, I estimate that this weeks report has taken me around 5 to 6 hours to compile and write, and the proposed change might add up to an hour to this.
As ever I welcome your comments/suggestions and criticisms and I look forward to reading them all.
Until next week.
