The previous eruption in the Reykjanes peninsula was between 1210 and 1240 CE. Therefore, they lasted for approx. 30 years. Even though THIS particular fissure might die down this year, it is quite likely other eruptions in this area will take many more years before "the nightmare" in this region will end. It might even take dozens of years before Grindavik is safe again to actually live in, but only time will tell.

Thanks as always! The eruption is fascinating, but condolences to those who live in the general vicinity. The lava flow west of Grindavik is already very close to the ocean, but as mentioned in the video, the lava flow may not advance much further due to the decreasing effusion rate. Still, 50 cubic meters per second is quite a high effusion rate, especially compared to the Fagradalsfjall eruptions and the other Reykjanes eruptions after they diminished in intensity. The Iceland Meteorological Office (linked in the video's description) published several new maps of the eruption's lava field. More area to the southeast has been covered, giving the May 2024 eruption a significantly different and even somewhat unique appearance on satellite, at least compared to the previous Reykjanes eruptions. I do wonder how long these eruptions, including the ones at Fagradalsfjall, last. This series may last decades, and some estimates even say centuries. I am so sorry for those living in the vicinity.

It's possible that the size of the eruptions decrease the further away they are from the source of magma. The December, February, March and May eruptions started near the Svartsengi/Blue Lagoon area and were large. The January 14 eruption, the most southerly one so far was the smallest so far, and barely progressed further south with that fissure next to Grindavik. Same kinda happened here. The strongest part of the eruption was near the source, while further south it was weaker.

Technically, it would have most likely reached it at least twice now. Iceland has done an amazing job diverting the lava. The quickest route to the ocean is right through the middle of the town since the town is much lower than the surrounding area. By diverting the lava the way they have, it’s forcing the lava into flatter ground. This allows the lava to pool instead of flowing downhill. While this does currently save the town it could also mean that at some point the town will be the path of least resistance for this lava to reach the surface and a fissure just like what we saw with this eruption will be in the dead middle of town. At some point, Earth will win this battle and claim the town. At this point it would just be easier and smarter to move the town

@@deathbycheese850 From what I remember of the seismic swarms and the magma chemistry the mantle plume appears to be the main source of material with an origin in the mantle from around Bardarbunga so the distance of the source probably does matter. Notably the the mid ocean ridge extensional eruptions are much much more severe when they occur near the hot spot core especially they occur along one of the fissure lineaments which serve as the path of least resistance for one of the major Icelandic stratovolcanoes though admittedly that changes the dynamics substantially by providing a large source of local melt at high pressures as seen with the Eldgjá fissure eruption of the Katla system in 939-940 or the more famous but smaller Laki fissure eruption from Grimsvotn. The point is that while the mid ocean ridge dominates the tectonics the rate of melt production appears to primarily be controlled by the mantle plume which feeds Iceland since the upwelling plume derived melt is much more readily available compared to the main mid ocean ridge sections elsewhere. Distance from that source is likely what actually matters though it should be noted that the hot spot appears to gradually be moving south.

@GeologyHub The problem is that there is no evidence supporting the inflow magma rate decreasing over time, as the rate of 6-7m3/s for inflow rate remained consistent since January as there was no changes. Not mention that we're still seeing inflation at sill storage area even after the eruption. So I would discard on your predictions of this eruption stopping if I were you, as I will have to note that this area's geological history clearly shows that volcanic activity can last decades to centuries. For example, refer to this area's last eruptive activity in 1210-1240 AD, it had 12 to 15 eruptive periods.
@sigisoltau6073
4 ай бұрын
I agree with that inflow rate. Towards the end of the last eruption, inflow at the magma chamber was around 3 cubic meters per second, while at the eruption site around 3 cubic meters per second were erupting. This tells me that magma was coming up at a rate of about 6 cubic meters per second. The reason why uplift seemed so slow before the current eruption may be because the rock has been stretched multiple times since October 25th last year.

Fiber Optic sensors buried in the ground. As many fluids (Lava and water) make a noise as they flow over ground. Noise or vibrations.

But I do not know where the above stats were obtained from.

That 'exponential deca' is not as fast as the pressure release when a balloon is popped. The continuation over 3 or more days seem to imply that the release is not all at once as the aperture (vents) are smaller than the pressure feeding it.

Wouldn't it be better if the peruvians did the scientific research. Most of the videos and science here for the Icelandic Volcanoes are by local or near by scientists who can at least read the icelandic research data from all the other icelandic support groups. Their interests are heightened by the fact the volcanoes are close to home. Some geologist may want to study El.Misti. But first he may need to learn to read Peruvian and to learn if there are existing support local support groups with recorded history of activity. (Seizmic, GPS, Fiber Optic, etc). LOL-I was thinking maybe it is the local peruvians themselves who ought to be informing the world. Good Luck.

No. No one knows if lava is not going to pop-up with in the defense walls or with in Grindavik town or the harbour. The lava flowed right to the North Town Defense Wall. If the lava is building a mountain of basaltic crust north of the Town getting higher and higher. Then it is like building a gradiant down hill to the Town. That is not actually protecting the Town. The lava is also filling the shallow land north of the Sundhnuka crator. So if that fills then more lava could flow in different directions or south to the Town.

Double-decker coaches in England have traditionally been 12 metres (39 feet 4 inches) in length, though many newer models are about 13.75 metres (45 ft 1 in). While 'highbridge' buses are normally about 20 centimetres (8 in) taller. So 12 meters squared would be 144 and that times another 12 would be 1,728 M³. Therefore with 2,000 cubic meters of lava erupted every second at one point from Iceland's eruption the volumn of lava was greater than volume of one square cubed bus (12 meters). So the volumn in double decker buses is one double decker bus cubed about every 95 hundreths on one second.
