Fuego
eklemetti | June 3, 2010The level of news-frenzy on some of the recent volcanic eruptions has died down, but if you're looking to see information on the many rumbling going on worldwide, look no further. Here is this week's Volcanic Activity Report put together by Sally Kuhn Sennert of the Global Volcanism Program.
Highlights - not including Pacaya, Yasur, Tungurahua and our friend in Iceland - include:
The eruption in the Marianas apparently came from South Sarigan volcano - at least according to the best guess by folks who work in the Marianas. This submarine volcano apparently shows evidence of young lava flows…
eklemetti | December 17, 2009Before it gets lost in the mists of time/finals, here is the weekly volcano report brought to us by the USGS and the Smithsonian Global Volcanism Program.
Highlights (not including Mayon, Soufriere Hills or Piton de La Fournaise):
Fuego in Guatemala produced ash plumes that reached 4.1-4.7 km / 13,500-15,400 ft along with avalanches of volcaniclastic debris.
Also in Guatemala, lava flows erupted from Pacaya, traveling hundreds of meters from the main vent area.
Manam in PNG produced an 3 km / 10,000 foot ash plume as part of its renewed activity this year.
The lava dome on Nevado del Huila…
eklemetti | November 18, 2009The latest news from the USGS/Smithsonian Global Volcanism Program Weekly Volcano Report ...
Highlights (not including Mayon) include:
Strombolian eruptions and small pyroclastic falls at Arenal in Costa Rica.
3 km / 10 000 foot ash plume from Bagana on Bougainville Island in Papua New Guinea.
Rumbling noises, ~4.5 km / 14 000 foot ash plumes and incandescence were all reported coming from Fuego in Guatemala.
Steam-and-ash from Popocatepetl near Mexico City reached 7.4 km / 24 300 feet.
Satellite images of Shiveluch revealed a large thermal anomaly - the new lava dome - along with multiple…
eklemetti | October 15, 2009Before we get to the latest SI/USGS Weekly Volcanic Activity Report (WVAR), I wanted to draw your attention to some nifty NASA Earth Observatory images from the current activity at Soufriere Hills in Montserrat. After a few puffs last week, the volcano is now releasing a relatively constant stream of ash and steam, this after ~10 months of quiescence. The two images, one on October 12 and one on the 13th, suggest there is a lot of a variability, day to day, in the plume. See the latest WVAR for more info on Soufriere Hills.
On to the Report!
Highlights this week (not including Soufriere Hills…
eklemetti | August 5, 2009We've made it to Ohio! Tomorrow I'll hopefully be returning to regularly scheduled updates, but until then, enjoy this week's SI/USGS Weekly Volcano Report.
Highlights include:
KVERT mentions that seismicity has increased recently at both Kizimen and Kliuchevskoi on the Kamchatka Peninsula.
~4 km / ~13,500 foot steam-and-ash plumes spotted at Colima in Mexico.
Rumbling noises, incandescent ejecta and ~4.3 km / 14,000 foot ash plumes at Fuego in Guatemala. Explosions were increasing as the August began.
It was a busy week in Guatemala, as ash/gas plumes were spotted at Santiaguito and Pacaya…
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 | May 28, 2009Your weekly dose of volcanic activity from the USGS/SI. (a little late thanks to an exciting day of column chemistry).
Some highlights include:
A 3.7 km / 12,000 foot ash plume from Karangetang in Indonesia (great name, eh?)
Lava flows, ash plumes and local ash falls from Slamet in Indonesia.
White and grey ash plumes rises to ~4 km / 13,000 feet from Colima, Mexico.
Blocks up to 2-m across were transported by lahars from Fuego in Guatemala. The volcano also produced ~4.6 km / 14,500 foot ash plumes.
Small ash plume spotted at Barren Island in the Andaman Islands of India.
eklemetti | April 1, 2009For those of you looking for real volcanic eruption news (no, there was no "Yellowstone eruption"), here is this week's SI/USGS Volcano Activity Report.
And speaking of April Fools Jokes, this is by far my favorite (mostly by its combination of volcanoes and baseball. How could you go wrong with two of my favorite things - hat tip to Fletcher for finding the article).
Highlights (beyond Redoubt) include:
Earthquakes, tremors and steam at El Reventador in Ecuador
12,000-15,000 foot (4-5 km) steam/ash plumes were spotted at Colima, the Mexican volcano.
A shockwave was felt 10 km away from…
eklemetti | June 23, 2008
Things have quieted down on the volcano-news front lately. I did catch a report that Fuego (Guatemala) is having small explosions (stombolian eruptions; link in Spanish), producing small (100s m-tall) ash columns along with some throwing incandescent blocks 30-50 meters from the vent. Just the typical noises expected at an active volcano. In the meantime, you can check out the volcanic hazards information that the Guatemalan survey (INSIVUMEH) has posted on their website. I'm always a fan of a country trying to educate their citizens of the real dangers of volcanoes and how to prepare.
