Dukono

Sally Sennert from the Smithsonian Institution sent me an email to say that this week's USGS/Smithsonian Institute Weekly Volcanic Report will be delayed due to the inclement weather in the Washington DC area. She can't connect with the server, so the report can't be updated on the Smithsonian website ... so here it is! Look for it to show up on the Smithsonian site with all the bells and whistles as soon as DC thaws out. And a big thanks to Sally for sending me the Report to post. ***PLEASE NOTE: Website posting of the SI/USGS Weekly Volcanic Activity Report for 3-9 February 2010 will be…

We've already talked about how many active volcanoes reside in Indonesia, but this week's USGS/SI update just drives that point home. Listed in the update are no less than 5 volcanoes were activity is being seen or is on the increase (Karangetang, Slamet, Dukono, Batu Tara and Makian). This doesn't mean mention the activity at Anak Krakatau, Rinjani or Semeru. Amazing. Anyway, highlights - not counting Indonesia or the South American trio - from this week's report (as usual aptly put together by Sally Kuhn Sennert) include: A ~8,000 foot / 2.4 km ash and steam plume from Bagana in Papua New…

Some brief tidbits from the volcanic realms: Active volcanism at NW Rota-1 Kilauea? Explosive? You might think of Kilauea as a volcano that generates impressive Hawaiian-style eruptions with fire fountains reaching 100s m and dazzling lava flows, but Don Swanson at HVO sees evidence of a big explosive event at Kilauea. This eruption was ~1,000-1,600 years ago and may have produced a plinian-scale eruptive column and threw cm-scale chunks up to 17 km from the vent. The intermingling of life and active volcanism always seems counterintuitive, but when you're talking undersea volcanism, all…

Here'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.
