Quoted: OK, when is it going to go boom? My patience is wearing thin and I am about to loose interest. View Quote If the magma supply transitions to a type that's more viscous and higher in CO2 content...or if one of the quakes opens up a conduit into the upper magma chamber through which sea water can enter in sufficient quantities. Rampino (of SUNY) did something on Krakatoa and stratification of the magma chamber as it relates to the eruptive sequence. Let me see if I can find it. ETA: All good things are behind paywalls these days, it seems... But here's a good listing of material that delves into topics we've discussed in the thread. |

(ETA) - without more information, this is a SWAG, but:
It's possible that more magma is intruding into the chamber and inflating it faster than it can be erupted. Curious about how much (if any) crust is being entrained in that melt, and the rate of inclusion. Thus: Is the chamber getting larger? Would love to talk to the IGN crew and see what the inflation (ETA: or deflation) rate of the summit is, along with the emitted gas types, ratios and magma makeup. Also see what is known about the plume component - evidence of an impingement as the eruption trigger? |

Found some data on the Volcanodiscovery page I linked earlier.
Right around the time of the start of the eruption there was approximately 120mm uplift of the fault from normal datum, along with a southward shift of roughly the same amount. The geodetic coordinate system has E, N and U(up) as its three axes. Looking at the U channel data over the last few days, one begins to see a slow decrease. The ridge is deflating due to lessening magma pressure. Stutzmech posted earthquake data that shows a gradual contraction of the radius of the quakes relative to the eruptive center (and presumably, to the magma chamber). Which makes sense if the chamber is starting to empty, and is more disc or elliptical (rather than spherical) in shape. Volcanic tremor remains somewhat constant, though I do see a lessening trend there as well...and tonight's fireworks aren't quite as energetic as the last several. Anyone else picking up on this? |

Quoted: Hey "experts" is the big wave happnen or what??? If it does, how much warning/time will the east coast have? View Quote The so-called "rotten rock" theory has largely been debunked. Back story: The Cumbre Vieja has a number of dikes (vertical magma intrusions) that act as dams to water when they solidify. The lavas are relatively high in sulphur dioxide; mix rainwater in with any residual amounts of the stuff and you get sulphuric acid. That begins to attack the solid rocks holding the joint together. It was postulated that if enough rot occurs and you get a quake of sufficient magnitude, the mountain will fail at the decay points. Think "Florida condo collapse" on a hella larger scale. New analyses tend to debunk the theory as the mountain isn't steep enough for a whole-scale collapse to occur...though you may get localized landslides (as with St. Helens). While significant it by no means disrupted the entire mountain. Relief of pressure on the cryptodome (and the ensuing lateral blast) did that. |

I 'wish' that something could be added to a few pics of the volcano and lava flow for scale and to have an idea of their sizes.
The volcano really grew in height over the last two weeks. |

View Quote Can you explain why the north end of the island looks like it came from a major erruption, the south end is showing a bunch of older smaller eruptions and now it is coming from the middle?

Is that island just small enough that plate movement doesn't effect it yet and the weakest area of the island is in middle so that is where it is punching through now? |

La Palma rocked by another earthquake – magnitude of 4.3
October 7, 2021 https://inspain.news/la-palma-rocked-by-another-earthquake-magnitude-of-4-3/ La Palma grocery store shaking - https://twitter.com/i/status/1446146764877275137 The latest quake, which follows a day of relatively quiet seismic activity, was recorded at a 12.17 local time in Mazo, at a depth of 35 kilometres. A second tremor, measuring 3.8 was recorded at roughy the same depth, and a third of 3.4 was recorded at Fuencaliente at a depth of 12 kilometres. In addition, scientists are monitoring a lava flow which broke off from the main flow into the sea, taking a new direction, parallel to the current one, in the area of El Charcon. The stream is working its way through an area of La Palma island dedicated to the cultivation of banana trees. The beach is referred to as Playa del Volcán, because it is near one of the areas which was reclaimed from the sea by the San Juan volcano in 1949. |

Is that island just small enough that plate movement doesn't effect it yet and the weakest area of the island is in middle so that is where it is punching through now? The northernmost crater is actually a caldera. Remember the magmatic system is thought to be a hybrid.. combination of hot spot, subduction zone and linear faults. The Canaries themselves follow the hot spot track over time, but you will get localized variances. La Palma started at the big cone as a triple junction rift, and eventually the chamber feeding it collapsed - causing the top to fall inwards. New activity (including the current magma chambers) trended southward along deep fault lines. If you look at the plate boundaries, the axis runs somewhat parallel. It is a fairly complex system. Not your textbook setup by any means, and is a great "live" lab. |

Quoted: Mantle plumes are large and deep. Fingers of magma coming up from it branch out like the branches of a tree. Even if the plume (trunk) has moved a bit... the branches extend laterally outward to encompass more than the whole island. So lava can erupt from anywhere there is a weakness it can push through.

Quoted: Feed is showing SO2 emissions at 13,100 tons/day, up from 8,700 previously. View Quote In my attempt to expand my knowledge as well I just looked up some info on SO2. When I was a kid in the 1980s the biggest climate concern was acid rain and the ozone hole both of which were blamed on SO2 emissions. This was right after the biggest concern was "the coming Ice Age" from the late 1970s. To stop acid rain and deforestation SO2 emissions were greatly reduce "to save the planet". However, in the research I just raid it says SO2 gas has global cooling effect. Meaning the environmentalists that saved us from acid rain gave us global warming. I wonder why the scientists don't talk about this aspect of the climate. To compare the volcano to the US SO2 "pollution", the EPA estimates that the US produces 35,616 tons a day vs this one volcano at 13,100. That begs the question, if La Palma keeps it up will winter weather come early this year? |

Lava vent (lower one) is now fountaining more and the uppers are primarily emitting gas and ash. U Channel on their GPS sensor is showing a deflation trend. Comments on Volcanodiscovery reflect this.
May be winding down, or may be cycling upon the next influx of deeper, hotter melt. Seismos will tell the story. If you get a lot more small quakes, things are refilling. Fewer, larger amplitude tremors indicates that the chamber is settling back into itself and is emptying. |
