Koryaksky (Koryak) in Russia
Yesterday in the USGS/SI update, I mentioned the current eruption going on at Koryaksky (a.k.a. Koryak). Today, the NASA Earth Observatory has some images of the plume from the Russian volcano heading out to the east over the Peninsula. The plume itself looks fairly diffuse and mostly whitish steam rather than laden with grey/brown ash. The last significant eruption from Koryaksky was a VEI 3 eruption in 1956-57 that produced ash fall and pyroclastic flows from the volcano.
One thing that is noted on the EO page is this snippet:
MODIS captured this plume days…
eklemetti | August 26, 2009The slow summer for volcanic eruptions continue. Only 11 updates in this week's USGS/SI report. Thanks again to SI's Sally Kuhn Sennert for compiling the news!
Highlights this week include (not including Kilauea) include:
Tungurahua in Ecuador produced some minor lahars on August 21 to go with steam-and-gas emissions.
Popocatépetl in Mexico produced an ash plume that reached ~8.2 km / 27,000 feet on August 20 and continued to produce steam-and-ash plumes throughout the week following.
Over on the Kamchatka Peninsula, both Koryaksky and Shiveluch produced significant ash plumes (reaching 3-5…
eklemetti | August 19, 2009Busy today with scouting out some field location for the class I'll be teaching this fall. Here's this week's USGS/SI Weekly Volcano Report. The report is a little more eventful than last week's, so enjoy!
Kliuchevskoi Volcano in Kamchatka, taken summer of 2009 by Theresa Kayzar.
Highlights include:
Three volcanoes on the Kamchatka Peninsula are currently producing ash plumes: Kliuchevskoi, Koryaksky and Shiveluch. Shiveluch has been having the most intense eruptions, but the former two are both producing ash-and-steam plumes that reach over 3 km / 10,000 feet.
Talang in Indonesia saws its…
eklemetti | August 12, 2009Even the SI/USGS Weekly Volcano Report seems a little light -- welcome to the dog days of summer!
Highlights from this week's report include:
"Thunderous sounds", incandescence and small plumes (hundreds of meters) with more frequent seismicity at Ibu in Indonesia.
A sharp increase in sulfur dioxide output was noted at Mayon in the Philippines on August 4 - from ~700-900 tonnes/day to almost 2,000 tonnes/day.
~3,000 meter/10,000 foot gas-and-ash plume from Bagana in Papua New Guinea - you can see it on this recent NASA Earth Observatory image.
Ash/gas plumes from Sakurajima in Japan rose to…
eklemetti | August 10, 2009Some more volcano news for the day ...
UPDATE 10:40AM Eastern: It has been pointed out to me that both of these articles are old. They apparently made it into my Google News feed thanks to a glitch in the magic interweb tubes somewhere. Just goes to show that blogging before coffee on a Monday after traveling across the country = bad idea. Sorry for any confusion.
A summit dome at Kelud during the 2007 eruption.
OLD NEWS ABOUT SARYCHEV PEAK IN JUNE 2009. An unnamed Russian volcano in Kamchatka is disrupting flights from Canada to Asia. No ID in the article on which volcano, and I couldn't…
eklemetti | August 9, 2009Does anyone else feel like this has been a rather quiet summer, volcano-wise? Maybe I've been too preoccupied by my move to Ohio, but I feel like beyond a few relatively minor events (Shiveluch comes to mind), the volcano news has been pretty slow compared to the spring of this year. Go figure.
The sulfur dioxide plume from the 2008 eruption of Kasatochi spreading over the northern Pacific Ocean.
Anyway, a few tidbits to tide us over:
Over eighteen years after the eruption, Mt. Pinatubo is still causing fatalities from the copious amounts of tephra deposited during the 1991 event. Five…
eklemetti | August 6, 2009In case you don't frequent the NASA Earth Observatory, I thought I'd call your attention to some images they recently posted that are, again, excellent shots of volcanism captured from space.
The current plume from Tavurvur Crater at Rabaul was shot by the MODIS imager on Terra in early August. The plume is mostly made of volcanic gases and steam, but minor amounts of ash are also found - and remember, even small concentrations of ash in the air can be hazardous to aircraft.
Shiveluch has been having a busy summer, with moderate-to-large plinian eruptions produced by the emplacement (and…
eklemetti | July 30, 2009This is likely my last update until the end of next week sometime, so feel free to use it for any new volcano news you might see. Look for the Erebus Volcano Profile to be posted on Friday sometime, followed by the vote for the next Profile. Next time I post I'll be (back) in the eastern time zone!
With that, I leave you with the latest USGS/SI Weekly Volcano Report.
Highlights (not counting Shiveluch) include:
Small ash plumes were spotted several times from Batu Tara in Indonesia.
Explosions, ashfall and earthquakes were reported at Nevado del Huila in Colombia.
There were reports of…
eklemetti | July 27, 2009Again, sorry about the paucity of posts. Getting prepared to move 3/4 of the way across a continent will do that. Look for the next Volcano Profile, this time for Erebus in Antarctica, to be posted sometime in the next week or so.
We did get some news over the weekend of a large eruption at Shiveluch. The volcano in Kamchatka has been active all summer, but on Saturday it produced a 5,000 meter / ~23,000 foot ash plume. This was accompanied by 170 earthquakes and multiple avalanches, likely produced by the collapsing dome on the summit of the volcano. There is a little more information about…
eklemetti | July 22, 2009Your volcano news!
Thanks, as always, to the USGS/SI Global Volcanism Program.
Highlights include:
The alert level at Sakurajima was raised from 2 to 3 by the Japanese Meteorological Agency. This was due to the increasing frequency of explosions at the volcano, some of which produced ash plumes up to 1.8-2.7 km / 6-9,000 feet.
Ash was reported up to 3 km away from Ibu in Indonesia. However, officials in Indonesia lowered the alert from 3 to 2, but tourists are still restricted from going with 2 km of the volcano.
Lots of activity at Shiveluch in Kamchatka. You can see some of the activity in…
eklemetti | July 15, 2009Your weekly dose of volcanism from the USGS/Smithsonian Global Volcanism Program.
Highlights (not counting Mayon), include:
The activity at Mando Hararo in Ethiopia appears to be a fissure eruption. Ground observations saw a 4-5 kilometers / ~2.5-3 mile fissure with new predominantly 'a'a lava flows that were 2-3 m thick ... the fissure was lined with scoria ramparts 30-50 m high. They did not see any active lava, though.
As some Eruptions readers have pointed out from the OMI SO2 maps, Sarychev Peak (Russia) is still producing gas-and-steam (with some ash) plumes, mostly drifting off to the…
eklemetti | July 1, 2009A wrap up of the week's volcanism, brought to you by Sally Kuhn Sennert and the USGS/SI Global Volcanism Program.
Highlights, not including Sarychev Peak, Redoubt and Shiveluch (busy week in the north Pacific), include:
A small ash cloud was spotted at Bagana in Papua New Guinea.
The Tavurvur cone at Rabaul (PNG) continues to glow at night and produce small ash/steam plumes.
The Santiaguito dome at Santa Maria in Guatemala produced 8,000-10,000 foot / ~2.9-3.3 km ash plumes, along with a lahar that carried blocks over 1.5 m downstream from the volcano.
A 25,000 foot / 7.6 km ash plume was…

Shiveluch volano in Russia.
Just like last summer seemed like a busy time for the Aleutians (Cleveland, Okmok and Kasatochi), this summer could be dubbed the "summer of Kamchatka-Kurils" (alright, it isn't that catchy, sorry). The biggest news was/is, of course, the sizeable eruption from Sarychev Peak in the Kuril Islands, but not to be outdone, Shiveluch on the Kamchatka Peninsula has starting playing catchup.
KVERT is reporting that Shiveluch produced a 7 km / 23,000 foot ash column on Monday, with increased seismicity to go along with the explosions. These explosions are generating the…
eklemetti | June 24, 2009Busy busy analysing on the multicollector ICP-MS today (but not busy enough to miss this).
Here's your weekly volcano news roundup from the USGS/Smithsonian GVP.
Highlights (not including Sarychev Peak) include:
Continued dome growth and degassing at Bezymianny in Russia. Starting next year, there will be live webcams for three of the major volcanoes (Bezymianny, Kliuchevskoi, and Shiveluch) on the Kamchatka peninsula! Now, that is exciting news.
The glowing coming from the vent in the Halema'uma'u Crater at Kilauea in Hawai'i is still prominent. The lava levels in the crater have been…
eklemetti | June 17, 2009Your weekly dose of volcano news brought you by the Smithsonian Institute GVP and the USGS.
This week's highlights (not counting Sarychev Peak and Turrialba) include:
13,000 foot / 4 km ash plumes from Rinjani in Indonesia. This is part of the continuing eruption there.
The alert level was lowered at Galeras, Colombia to "Orange" after intense eruptions last week.
The current lava dome at Redoubt is 1 km long, 460 m wide, and 200 m high according to the latest images from the Alaskan volcano.
18,000-23,000 foot / 4.8-7.7 km ash plumes from Shiveluch in Kamchatka, along with thermal anomalies…
eklemetti | May 15, 2009Volcano news ahoy, today brought to you by Islands.
Lake Kivu, located along the border the Democratic Republic of the Congo and Rwanda
A gorgeous satellite image (brought to us by the NASA EO) of a steam plume and ash from the ongoing eruption at Shiveluch in Kamchatka. The ash distribution stands out remarkably well on the white snow, with the central circle of ash near the vent/dome and then the wind-aided ash blanketing the terrain to the northeast of the volcano (and a little bit to the south).
Nature has a post reminding us that one of the big hazards at Nyiragongo/Nymuragira is not…

Shiveluch volcano in Russia. Image courtesy of KVERT.
Over this past weekend, Shiveluch in Kamchatka experienced a plinian eruption, producing a 7-km / 23,000 foot ash column. The NASA Terra satellite caught a great image of the ash plume over the snowy landscape of the Kamchatkan Peninsula on April 26, 2009. KVERT issued these comments on the current eruptive activity:
Seismic activity of the volcano slightly decreased but continues to
remain at high levels. A continuous spasmodic volcanic tremor and
series of weak shallow events continue to registering at volcano at
present.
According to…
eklemetti | April 22, 2009Has a week gone by already? It is time for another USGS/Smithsonian GVP Weekly Volcano Activity Report.
Highlights (beyond Fernandina, Pagan and Redoubt) include:
A new underwater eruption at NW-Rota 1 in the Mariana Islands.
Increasing seismicity and incandescence from the rhyolite domes forming at Chaiten, Chile.
A spike in sulfur dioxide emissions from Kilauea, Hawai'i to 700 tonnes/day (up from a 2003-07 average of 150 tonnes/day).
4.5-7.5 km / 15-26,000 foot ash columns produced at Shiveluch in Kamchatka from new lava dome.
Continued dome growth and ~6 km / 26,000 foot ash columns from…
eklemetti | April 16, 2009Here's the latest Global Volcanism Program activity report for worldwide volcanism. Some of the highlights (beyond Fernandina and Llaima) include:
Vulcanian-style eruptions at Sakurajima, Japan. And guess what? There is a Sukarajima webcam! {Hat tip to Eruptions reader Jodie Morris for this link}.
Strombolian-style explosions and avalanches associated with lava flows at Arenal, Costa Rica.
A 10,000 foot / 3,000 meter ash plume from Dukono in Indonesia.
Satellite imagery exposed a thermal anomaly in the dome at Shiveluch on the Kamchatka Peninsula.
eklemetti | December 28, 2008
News is filtering in that Koryak (aka Koryaksky) Volcano in Kamchatka might be heading towards an explosive eruption. The details are scarce, but it seems that a breach on the northwest slopes of the volcano might cause an explosive eruption, however, it is not clear why this is. All this talk has caused the Petropavlosvk-Kamchatsky Airport (~13 miles northeast) to close in fears of this potential activity.
Koryak is yet another potentially active volcano on the Kamchatka Peninsula, along with currently active Bezymianny, Kliuchevskoi, Karymsky and Shiveluch. The last eruption at Koryak…
