In the last couple of days, there has been 80mm of uplift recorded at station LP03, on the downslope side of the active vent series.
And then you have this:  Harmonic tremor - 18Hz line. Indicates magma movement in the plumbing. Coupled with an increase in volcanic tremor strength, I think we'll soon see additional activity. Possibly west of the current vent complex. If a quake of Mag 5 occurs anywhere near the surface given this dynamic, things will likely open up. |

For the western flank to collapse? At some future point, but unlikely at present. What's in question is the capacity of the existing vent system to deal with a greater influx of magma. The fact that uplift is occurring indicates it's not being erupted as fast as it's being supplied. Get enough uplift in a brittle area (say, at the 2-3km depth) and it'll cause the cap rock to fail, resulting in an earthquake and fissuring. That means new vents. |

Does this now have three vents we’re seeing? The large main one, the jet-spewing one behind it, and a more sedate lava pumping vent up front that’s providing the down slope lava?

I've been told by a friend in hawaii that you really start paying attention when the vents aren't releasing magma but are still releasing gases (or otherwise showing signs of building pressure) ... or when the vent collapses (read: lava possibly going elsewhere).

That would be correct. Outgassing is a precursor to an eruption, which is one reason why collections are done any time you see other tell-tale signs of magmatic activity. If the vents close and gas emissions are still occurring but no material is being erupted, you're getting into some high pressure levels. Something will give. |

GeologyHub: La Palma Eruption Update; New Evacuations, Large Earthquake
 La Palma Eruption Update; New Evacuations, Large Earthquake "The La Palma / Cumbre Vieja eruption is now in its 27th day. So far, more than 6 square kilometers have been covered with lava, and 40 hectares of new land have been added to the island. On October 13th, the largest earthquake during the overall eruption occurred, rating as a 4.5 on the richter scale. Additionally, in recent days, more people have been evacuated as the lava flows split into two new branches. This video will discuss what is likely to happen next as this Spanish Canary Island volcano." |

The magmatic system of the Canaries is a hybrid of plume, subduction zone and linear fault series. A quake at that depth indicates a plume head impingement is ongoing or is imminent. See Phase 2 of the graphic below. ETA: This is a depiction of a pure plume-driven hotspot. The Canary Island chain is near enough to the African plate that subduction zone magmatism has an influence on the system.  ETA 2: First impression is that the quoted source is weapons-grade whackadoodle but the basic geology is pretty close. I'd like to know where that epicenter depth figure came from, though. |

Here's another good plume graphic:
 Note the curly areas at the bottom. You've seen these at the lower part of a mushroom cloud. That's known as a Rayleigh-Taylor Instability, and is the mechanism whereby crustal melt is entrained in the plume and subsequently erupted. |

Vesuvius was not a plume driven eruption. Subduction Zone. Explosive rather than effusive. Lots of ash, whereas the La Palma ash output is lower for the amount of material being erupted. A large igneous province scale eruption (think Siberian or Deccan Traps) would put a gigantic amount of SO2 into the atmosphere but it would take centuries to do so. You'd see a degree or two yearly potential drop, which would be vastly offset by the greenhouse effect of the erupted CO2. ETA: You want global warming?

LP03 U channel data shows a 70+ mm drop in elevation for the 24h period starting from 00Z on 15-OCT, and LP04 is down around 20mm. Also noted a recent (12h) earthquake swarm in the upper chamber. Some were of pretty decent amplitude. |

In other words, just a little less energy than a 10mm Mag round at the muzzle - but that's an argument for one of those shooty threads. Computer models have shown there would be a non-trivial ground wave amplification effect at the antipodal point. Combine with a relatively thin crust and plume generation/flood basalt eruptive initiation is a possibility, though not absolutely proven to date. There's the matter of timelines...how long afterwards would a magmatic pulse reach the surface? Long enough so that cause may not be accurately related to effect? Should I ever cross paths with Rampino (in real life or online) I'm going to make it a point to discuss the theory at length with him and see what the modern day consensus is. |

It seems more likely that the planet expanded from the core, the crust cracked up as it continued to grow and things wound up where they are when the expansion was done. |
