    "KEY POINTS:
    • The volcano generated Rayleigh waves about 15 min before the giant eruption with no apparent surface activity
    • These waves dominated in 0.03–0.1 Hz with amplitudes comparable to the amplitude of M4.9
    • Seismic stations 750 km from the volcano and appropriate data analyses allowed [them] to capture precursors of the catastrophic eruption..."

  6. Wicked smart scientists calculate how long volcanoes on Jupiter moon Io have been active. Measure relative abundance of 2 sulphur isotopes belched into the atmosphere then reprocessed as crust — bias toward heavy sulphur. Compare ratio to early solar system meteorites. science.org/content/podcast/ve

    [as a geologist and an adventure rider – and a Colorado resident that loves history - I have travelled all over this area; first photo is mine, my motorcycle under the Apishapa Arch in Aguilar, Colorado, a 1930s Civilian Conservation Corps project through a volcanic dyke, ‘coincidentally’ providing better access to land that a senator had purchased up around Cuchara and Cordova Passes]
