Recent Icelandic rifting events have illuminated the roles of centralized crustal magma reservoirs and lateral magma transport, important characteristics of mid-ocean ridge magmatism. A consequence of such shallow crustal processing of magmas is the overprinting of signatures that trace the origin, evolution and transport of melts in the uppermost mantle and lowermost crust.
Here we present unique insights into processes occurring in this zone from integrated petrologic and geochemical studies of the 2021 Fagradalsfjall eruption on the Reykjanes Peninsula in Iceland.
Geochemical analyses of basalts erupted during the first 50 days of the eruption, combined with associated gas emissions, reveal direct sourcing from a near-Moho magma storage zone. Geochemical proxies, which signify different mantle compositions and melting conditions, changed at a rate unparalleled for individual basaltic eruptions globally. Initially, the erupted lava was dominated by melts sourced from the shallowest mantle but over the following three weeks became increasingly dominated by magmas generated at a greater depth.
This exceptionally rapid trend in erupted compositions provides an unprecedented temporal record of magma mixing that filters the mantle signal, consistent with processing in near-Moho melt lenses containing 107–108 m3 of basaltic magma. Exposing previously inaccessible parts of this key magma processing zone to near-real-time investigations provides new insights into the timescales and operational mode of basaltic magma systems.

The Minister of Justice is not too happy with turisti...
Not sure why the MoJ is fronting this.
This is interesting...

Should be if the iff8cials there don’t get cranky.
Best kind of volcanic eruption, least likely to damage any infrastructure, not likely to make people homeless or put populations in harm’s way.
Not sure how easy the area is to access.
But if the government is smart it’ll tell turisti to use their noggins while making some money off their natural wonder.

You guys are too good, makes me feel like a little sand pebble.
Well, that didn’t take long...
That's some pic at the link.
Not much cooking this morning. I love government.

Nice
Volcano wall slides! Drone flies right next to boiling lava pot!
