Quote HistoryQuoted: 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? Because this is how you get global warming... Damn. So what are the chances this thing burns for 87 million years? Or even more than a few months |

Damn. So what are the chances this thing burns for 87 million years? Or even more than a few months Keep a watch on several things: The amount of uplift of the ridge. The presence and intensity of harmonic tremors on the seismos. The presence and location of earthquake swarms below the island. A high amount of SO2 and the presence of He3 in the emitted gas mixture. As long as the uplift stays constant/fluctuates moderately and you have the other conditions occurring, chances are it'll keep erupting. Taken together, the factors indicate a healthy flux of magma into the system - magma of deep mantle origin. Steady inflation of the ridge is a sign that material input and output are in balance. Based solely on observations of available data, it would be easier to predict a cessation of activity than it would a duration estimate without knowing how much athenosphere-derived magma is available and how fast it's rising into the chambers. |

I saw a quake of moderate intensity at 2km depth a bit ago. If the deflation trend reverses itself, expect another vent to open.

An hour and half ago it was going crazy! Especially the lowest vent. The lava was hotter (bright white hot!), flowing quicker and with greater volume than I’ve seen any other time since this started. Scroll back if you’re on a computer to around 10pm to see it. The past hour it quieted down but right now she’s coming back to life….

I do not want to see a massive explosion or island destruction event while there are people still on the island. Active volcanoes are real-life geology labs, much as a supercell thunderstorm's life cycle can be studied and the data used to refine predictive algorithms. Weather is another passion of mine (for that matter, many Earth sciences) and while I'd love to analyze a long-track F5 in real time I DON'T want to witness it moving through densely populated areas. In terms of what this volcano is doing: Much is understood about how certain types behave, but at the same time, much isn't. We can't actually dive into the vent and all the way to the core/mantle interface to see how the system is being supplied with magma - and with what type(s) over the lifetime of an eruption. You have to rely on some theories...some generalized, some refined...in order to gauge the duration and effects of an event. The chance to analyze fresh erupted material helps to bolster theories and refine your data sets. Along with them, your models get better. Anyone remember the BBC TV movie "Supervolcano" about Yellowstone? In it was portrayed a predictive supercomputer 'VIRGIL' (which was somewhat crash prone). Though not as elegant as the machine which was depicted, some of the larger ones in existence today are capable of running sophisticated thermodynamic modeling series. All these data you can get to feed them helps to refine their thinking processes (as AI is factoring into analytics more and more). |

Assuming this wasn't an optical effect of a low contrast video system and truly is a reliable indicator of magma temperature...and the right combination of gases are present: You're getting a flux of deeper-sourced magma, possibly moving faster up the plumbing than before.

Off to look at more data. Station LP03 shows an 80+ mm drop over the past couple of days. That may explain the hotter-than-normal magma; the lower portions of the upper chamber may be sourcing it. Would explain the shallow quakes and localized deformation effects too.
Magmatic systems act as ladle cars in steel making do - both are very good insulators of their contents. The latter quite possibly has its origins in the former.

Data feeds show a marked decrease in volcanic tremor amplitude and harmonic tremor strength is steadily trending downward.
IGN and local authorities holding a press conference at the moment on the feed...in Spanish. I'm guessing they're discussing the reduction in strength and a potential end to it...if more magma doesn't get injected into the plumbing. |
