Guatemala

Lots of little pieces of news I've run across ... time to play a little catch up. Stromboli: A volcano after Don Ho's heart. Every once in a while, my RSS feeds will dredge up some articles from years gone by ... and this week there were two New York Times pieces that are a few years old, but interesting nevertheless. The first is about research conducted by Dr. Robert Sohn at WHOI on explosive undersea eruptions. The second is work by Corr and Vaughan about finding subglacial volcanism in Antarctica. Both are interesting reads if you missed them (like I did) the first time around. Yesterday…
Tourists hiking next to an active lava flow on Pacaya in Guatemala in 2006. I'm flying back to Ohio today after a successful few weeks of fieldwork/paper writing. Apparently I have a pile of tomatoes waiting in our garden in Granville ... ! On to news: To go with the news that lava flows from Kilauea creep ever closer to structures in Kalapana, the NASA Earth Observatory posts its first volcano image in a bit. The shot shows the steam-and-gas plume from the Halema`uma`u Crater in Kilauea's summit caldera. You can also see some video of the lava flows near Kalapana as they move along the road…
An explosion at the Santiaguito dome at Santa Maria in Guatemala. Now, we've been talking recently about funding volcano monitoring - specifically with the threat that KVERT in Russia will close down after today (June 30). Well, Jessica Ball over at Magma Cum Laude has another worthy volcano observatory that needs your help. The Santiaguito Volcano Observatory, run by the INSIVUMEH in Guatemala, is the main station to watch over the activity at Santa Maria and the (very) active Santiaguito domes near the Pacific coast of the country. However, this observatory is run an a shoestring budget if…
The latest update from the Smithsonian/USGS Global Volcanism Program! Highlights (not including Taal, Eyjafjallajökull and Bezymianny) include: Another thermal anomaly was spotted on an Kuril Island volcano - this one being Tiatia. The volcano has no seismic monitoring network, so the thermal anomaly is all that has been observed. Lava flows and strombolian explosions continue at Guatemala's Pacaya. Some of the explosions have launched bombs hundreds of meters into the air. Kliuchevskoi was another busy Russian volcano, with a large thermal anomaly and ash explosions that produced a plume at…
Looking for some volcano news - you've found it. A shot of volcano "tourists" near the erupting Pacaya. Photo by the Associated Press. Eruptions reader Dr. Boris Behncke dropped a note that Kilauea has not one but two active lava lakes right now. The lava lakes can be seen on the webcams for the Halema`uma`u Crater and the Pu`u O`o flank vent. The latest status update from June 6th by the USGS Hawaiian Volcano Observatory talks about both the summit and rift activity (video) on Kilauea as well. Meanwhile, Hawaii 24/7 has a piece in the Volcano Watch series about whether residents of Maui need…
The 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,…
Quick news on Memorial Day (in the US at least): Ash soaked by rain from Tropical Storm Agatha on the roofs of homes in Guatemala after the late May eruption of Pacaya. Sixteen scientists were evacuated from islands in the northern Marianas due to the eruption of the unnamed submarine volcano south of Sarigan Island. The eruption is continuing to be monitored closely by the USGS and National Weather Service as the plume - which is most steam with minor ash - could disrupt air traffic in/around Saipan. The latest USGS CNMI update:Seismicity at a single nearby station on Sarigan Island declined…
Dark ash covers an American Airline 737 on the tarmac at the airport in Guatemala City. Two volcanoes are making headlines right now (and neither is in Iceland). As I mentioned yesterday, Pacaya in Guatemala erupted (video) causing widespread disruption of life in the nearby Guatemala City and costing two people their lives (including a TV reporter who got too close to the vent). Almost 2,000 people have been evacuated from the region near the volcano. The BBC has posted some impressive video of the eruption of Pacaya, showing the strombolian explosions sending basaltic tephra high into the…
This week has been destroyed by workshops and my last death throes with a paper I am submitting on my research in New Zealand. And to think, I thought it might settle down a little after the students left. To news! Ash fall on a taxi cab near Guatemala's Pacaya. Pacaya in Guatemala erupted yesterday causing evacuations of people near the volcano and the closure of Guatemala City's main airport. Pacaya is a mere ~25 km from the capitol of this Central American nation. Tragically, a news reporter from one of the capitol's TV stations died when they were struck by volcanic debris, again…
An undated painting of the island volcano of Ischia near the Bay of Naples, Italy. Guess what? It is the end of the semester (well, school year) here at Denison, so I might be a little busy for the next couple weeks. Here are some news bits (with special thanks to all who emailed me some of these links): Boris might have more information or opinion on this, but Italy is back in the news concerning the threat of volcanism to the country. This time the volcano is Ischia, off the coast in the Bay of Naples. Guido Bertolaso of Italy's civil protection agency is quoted as saying that the "magma…
Guatemala's Santa Maria volcano with the dome complex visible in the foreground. I got a tip the other day from an Eruptions reader of something afoot at Guatemala's Santiaguito - a part of the larger Santa Maria volcano - and sure enough, there are reports today that the volcano is experiencing an "unusual and violent" display. The articles I can find only mention that ash was spread over six provinces in the western part of the country, which is unusual for this volcano that normally produces diffuse ash plumes and minor dome collapse avalanches (at least in the recent past). The Institute…
The weekly volcano report, brought to you by our friends at the Smithsonian Global Volcanism Program and the U.S. Geological Survey. Highlights (not including Mayon, Nyamuragira and Turrialba): Eruptions continue at Piton de la Fournaise on Reunion Island - heck, this would be the volcano news if it wasn't for all these other, more explosive systems getting in the way. Lava fountains, flows and pools were the order of the day in the SW Dolomieu crater until the 12th of January. Chaiten in Chile continues to chug along - block-and-ash flows were seen and ash plumes continue to emanate from the…
Before 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 in…
The 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…
The SI/USGS GVP site is back up and running - and they've posted a new weekly volcano activity report. Enjoy! Highlights include: Nevado del Huila in Colombia has been showing signs that a new eruption might be starting. Seismicity has increased and minor ash fall has been reported, leading to an increase in the alert level at the volcano to "orange" (high). Ebeko in the Kuril Islands off Russia and Japan produced a ~8.8 km / 29,000 foot ash plume. Thermal images of the crater at El Reventador in Ecuador show that hot material is filling in the dome complex - this followed ash-and-steam…
Before 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…
We'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…
Your 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…
A 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…
The weekly USGS/SI roundup is out. Highlights (beyond Slamet) include: Explosions (some heard 25 km away) and incandescent blocks that started fires at Galeras, Colombia. Ash and tephra being thrown tens of meters into the air and a 4-m tall spatter cone being built at Pacaya, Guatemala Also in Guatemala, Santa Maria's Santiaguito dome produced ash plumes and explosions. Steam, ash and sulfur odors from the continuing eruption at Redoubt, Alaska. Increased seismicity, steam and ash plumes along with a thermal anomaly at El Reventador in Ecuador
