Batu Tara

The latest news from the world of volcanoes, brought to us by the Global Volcanism Program, USGS and the Smithsonian Institution. They are also brought to us by Sally Kuhn Sennert - and if you have a question for her about her job at the GVP preparing the Weekly Volcanic Activity Report and all things volcanic (and hopefully it won't end like another recent volcanically-mitigated interview). Some highlights (not including Gorely and Sakurajima): Ioto (aka Iwojima) in the Volcano Islands of Japan produced an ash plume of unknown height. The volcano has frequent phreatic eruptions and abundant…

To the updates! Batu Tara volcano in Indonesia. The volcano is currently producing small ash plumes. I was distracted enough by trying to figure out a way to teach about Miller Indices that I plum forgot to post this week's USGS/SI Weekly Volcanic Activity Report. It was a fairly quiet week so you didn't miss much. Enjoy it at your leisure. Rabaul must be positioned on the globe in such a way that NASA's Aqua satellite always gets a good shot at it. The Earth Observatory posted a new image of the plume from Rabaul and it looks thicker and more ash-laden than the image posted a few weeks ago.…

This 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…

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…
