It can be estimated that current eruption period that has now started on Reykjanes peninsula is going to last until the year ~2400 to the year ~2600. During this time shortest time between eruptions is 1 year but the longest time between eruptions might be up to 10 years. How this going to be exactly is a big question but this estimate of mine is based on the limited historical data that I have read somewhere (I no longer remember where that was).<\/p>\n<p><strong>News items with videos<\/strong><\/p>\n<p><a href=\"https:\/\/www.ruv.is\/frett\/2021\/03\/22\/tower-breaks-again-lava-gushes-forth\" target=\"_blank\" rel=\"noopener\">Tower breaks again, lava gushes forth<\/a> (R\u00fav.is)<\/p>\n<p><strong>Web cameras now with English text<\/strong><\/p>\n<p><a href=\"https:\/\/www.ruv.is\/frett\/2021\/03\/20\/live-feed-from-iceland-volcano\" target=\"_blank\" rel=\"noopener\">Live feed from Iceland volcano<\/a> (R\u00fav.is)<br \/>\n<a href=\"https:\/\/youtu.be\/BA-9QzIcr3c\" target=\"_blank\" rel=\"noopener\">Live from Geldingadalir volcano, Iceland<\/a> (YouTube)<\/p>\n<p><strong>R\u00fav has moved the stream to YouTube only.<\/strong><\/p>\n<p><a href=\"https:\/\/www.mbl.is\/frettir\/innlent\/2021\/03\/22\/beint_eldgosid_i_fagradalsfjalli\/\" target=\"_blank\" rel=\"noopener\">Beint: Eld\u00adgosi\u00f0 \u00ed Fagra\u00addals\u00adfjalli<\/a> (mbl.is, this camera is on the other side compared to the R\u00fav camera)<br \/>\n<strong><br \/>\nUpdate at 23:57 UTC<\/strong><\/p>\n<p>According to the evening news on R\u00fav the lava and magma that is now flowing into the valley of Geldingadalur is around 1200C and is a primitive magma of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Tholeiitic_magma_series\" target=\"_blank\" rel=\"noopener\">Tholeiitic magma series <\/a>(Wikipedia). The source of this eruption is a magma chamber with the depths of 17 km to 20 km and the origins of the magma it self is far deeper into the hotspot below Iceland. This magma has a lot of CO and CO2 gases that are highly dangerous. There is also a lot of SO2 gas in the eruption and that is dangerous gas.<br \/>\n<strong><br \/>\nNews in Icelandic about this<\/strong><\/p>\n<p><a href=\"https:\/\/www.ruv.is\/frett\/2021\/03\/22\/hraunkvikan-synir-beintengingu-vid-midju-mottulsins\" target=\"_blank\" rel=\"noopener\">Hraunkvikan s\u00fdnir beintengingu vi\u00f0 mi\u00f0ju m\u00f6ttulsins<\/a><\/p>\n<p><strong>Rate of updates<\/strong><\/p>\n<p>Since the eruption is now in stable activity I am going to limit update to if anything major happens.
