john.r.davies Posted March 28, 2021 Report Share Posted March 28, 2021 As of now, 2030 on Sunday, I can see a pixelated pic that loks to be in dim daylight (this is Iceland so maybe) and a thunderous soundtrack, with lots of onlookers, but the activity is a lot less dramatic than before.

RobH Posted April 5, 2021 Report Share Posted April 5, 2021 Dramatic action - new fissures 500m long, opening to the NE of the old eruption. https://www.visir.is/g/20212093433d/ny-sprunga-ad-opnast-a-reykja-nes-skaga Quote Link to post Share on other sites

Peter Cobbold Posted April 5, 2021 Author Report Share Posted April 5, 2021 the mbl webcam shows the original eruption is quieter, but both cones still flowing lava http://k100streymi.mbl.is/spila/webcam0 But the new fissure appears to be the more active. Quote Link to post Share on other sites

john.r.davies Posted April 5, 2021 Report Share Posted April 5, 2021 That river of lava is terrifying! The lava field around the original cones looks more like a scree slope from a slate mine, than the product of a lava flow. Jagged plates piled atop each other. Is there a reason for that, Peter? I'd expect it to look more like this (from Hawaii) John Quote Link to post Share on other sites

I'd expect it to look more like this (from Hawaii) John John, IIRC the smooth surfaced ropy stuff has cooled in situ and is called pahoehoe while the lava that looks like a heap of coke is comprised of scoria, ejected magma that solidified in air or upon impact. Its is called aa (pronounced ah-ah after the sound made when walked upon). But I suspect there are graduations between the two..... Peter Quote Link to post Share on other sites

RobH Posted April 7, 2021 Report Share Posted April 7, 2021 (edited) And yet more drama. A third vent has suddenly opened on the hill between the two existing ones, and lava from it is getting awfully close to one of the cameras...... http://k100streymi.mbl.is/spila/webcam0 edit - that camera seemed to stop at about 08:19 and is just playing a recorded loop, so it has probably been eaten by the lava now. second edit - no, it only ate the power cable it seems.

The name dates back to Erik the Red, a renegade expelled from his home on the island who set up a colony to the west, which he called Greenland. To attract more settlers he toldd them to avoid "Ice"land. The tourist office invented the term "Land of Ice and Fire", despite the fact that nothing burns much in an eruption, a bit of herbage and some gas. Likewise volcanoes dont emit smoke, its ash.
