Something a little different today. I was having a look at the volcanic activity in Alaska as I do every now and then as I have friends in the shadow of Redoubt and ran across this image.
If you ever wondered what volcanic ash looked like when viewed with an electron microscope, heck even if you didn’t, you know now. It’s little wonder the stuff is so damaging.
This ash sample was collected in Sand Point by Kathleen Harper a Sand Point resident. The ash consists of exclusively of juvenile vesicular glassy particles with few crystals.
There are a number of volcano’s in Alaska, this one Pavlof is currently a “Code Orange” defined as: ORANGE: Volcano is exhibiting heightened or escalating unrest with increased potential of eruption, timeframe uncertain, OR eruption is underway with no or minor volcanic-ash emissions [ash-plume height specified, if possible].
If you are interested in such things have a look around the Alaska Volcano Observatory.
