Friday Flotsam: USGS/SI update and the plume from Rabaul

Your (late) USGS/SI volcano update and more shots of the ash plumes from Rabaul.

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. What this says about any potential future activity at Tavurvur crater at Rabaul is unclear, but it does show that the volcano is on a constant "simmer" right now.

    While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.

    Why we're so self-critical of ourselves after meeting someone new

    A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.

    Surprising Science

    We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.

    NASA launches ICESat-2 into orbit to track ice changes in Antarctica and Greenland

    Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.

    Firing three pairs of laser beams 10,000 times per second, the ICESat-2 satellite will measure how long it takes for faint reflections to bounce back from ground and sea ice, allowing scientists to measure the thickness, elevation and extent of global ice

    Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
