La Soufrière Today: 30th December 2020

[@GuillaumeLevieuxFromEarth]

Merci Stacey et Richie pour votre beau travail d'information scientifique. Votre message est toujours aussi clair et précis !

[@marlene97280]

For all Caribbean brother, all my support from Martinique ! Que Dieu vous garde, et que le futur soit prospère.❤️

[@jozinedurrant3250]

I understand much better. Thanking for the information

[@stinahumana]

Thank you very much from Richmond, St. vincent.

[@baihongliang]

I live next to a volcano. Thanks for the information!

[@StephOzz]

I think that this is a wonderful video. And made in such a short time. Maybe diagrams, photos or animations of effusive vs explosive eruptions and of pyroclastic flows and lahars would help more people to understand.

[@Earthy9025]

🌷Thank you very much.

[@gloriamclean7139]

Thank you for sharing

[@darrellcatwell1178]

What about Kick'em Jenny ? Has anyone decided to check how that's faring as yet ? And what about the other volcanoes along the chain throughout the entire Caribbean area? Are we to expect others to kick off soon ?

[@UWISeismicResearch]

Kick em Jenny is at normal background levels and the other volcanoes are at that as well. The volcanoes along the chain are not connected. Although they are formed by the same process i.e. subduction at the plate boundary, they do not share the same magma chamber nor are there long conduits. A volcanic eruption on one island, cannot trigger an eruption on another island.

[@davidpnewton]

The thing people simply don't think about is the actual physics involved. All of the volcanoes in the arc are indeed caused by the same process of subduction. However the local tectonic conditions also cause a lot of differences in behaviour for each volcano. The two major factors are plate subduction angle and the exact local rocks. The plate subduction angle is quite literally how steeply one plate is diving beneath the other. The conditions necessary for volcano formation are that melt exists, and that melt forms at the same depth each time for subduction zones. Water is driven off the subducting plate and lowers the melting temperature of the crust above. That then migrates upwards and forms volcanoes. The subduction angle determines how far from the trench this process occurs. The melt is formed at a point determined by the subduction angle. As intimated in the previous paragraph, the melt is NOT from the subducting plate. It is from the overriding plate. Therefore the geology of the overriding plate determines the geology of the melt. All active volcanoes save for Ol Doinyo Lengai in Tanzania produce silicate lavas. It produces natrocarbonitate lava. The biggest factor in eruption style for each volcano is silica content of the melt: the more silica, the more viscous, the more dangerous and the more likely there is to be a big boom. The other factor is that overlying geology also determines exact volcanic edifice placement: volcanoes are much more likely to form at pre-existing faults as those provide a path for melt to reach the surface. The only time that individual volcanoes influence each other is when they are directly adjacent to each other. That means like Kilauea and Mauna Loa or Grímsvötn and Bárdarbunga or the Three Sisters system. It's a maximum of 20 to 25 miles apart. That's because the pressurisation level and thus shape of one directly affects the shape and thus pressurisation level of the other. Dikes from one system can also intrude into the other as happened with the Holuhraun eruption in 2014.

[@babysaho9576]

Could the vibrations from the recent drilling for geothermal energy have weakened the walls of the conduits inside the volcano thus allowing for this eruption?

[@jonoliahjohn6800]

No. Simply put, the force that the drilling put on the walls of the volcano would not be enough to effect any real change. Plus, only hot air would have been released at that point. As a matter of fact, the removal of hot air would decrease the pressure in the volcano if it were a closed system.

[@silasla]

Would like to know if an explosive eruption at St. Vincent could be a danger to the people in Martinique and Guadalupe?

[@realryandugger]

Any chance of setting up a live Web cam?

[@UWISeismicResearch]

Installation of additional volcano monitoring equipment is our priority at the moment. Installation of cameras limited to scientific observation is in progress

[@Eddy12700]

will there be a live camera?

[@mauricestokes3635]

it will be really nice if they would do that or a live feed In a helicopter

[@ivornworrell]

With all due respect to the learned professor, if the volcano is going to erupt it will erupt & all the monitoring equipment in the world cannot prevent it.oh well, I think I better start preparing my will.

[@juarezcastelo]

I think the purpose of monitoring the volcano is to get warnings with enough time to evacuate.

[@ivornworrell]

​@@juarezcastelo ok, but whaddif it erupts spontaneously & violently in a mushroom cloud of HOT ash & lava, there'll b little to no time to evacuate bcz one wud not have even seen any warning signals! & depending on the length of the radius of the mushroom cloud, the whole island could be within its ambit! so do u now c y i'm in haste to prepare my will?

[@UWISeismicResearch]

@@ivornworrell There has been lots of research done on this volcano and there is a hazard map of the island that shows the zones and there are safe zones that will not be impacted by the volcano. The monitoring equipment should give us signals to help inform NEMO should activity increase. Yes it's all well and good to be prepared so do take any steps you think necessary.

[@ivornworrell]

@@UWISeismicResearch i hear u, but this safe-zone theory all hindges on the premise that the volcano will erupt in a predictable manner, but if it erupts haphazardly, then this safe-zone hypothesis is OUT THE WINDOW.

[@godfreypoon5148]

haha pyroclastic flow go brrrr

[@cameramon]

I'm not a scientist (CameraMon) but that theory about volcanoes being independent of each other is hypothetically incorrect , i think or rather in my opinion that they are all connected; it's like the blood in your body, just saying.

[@UWISeismicResearch]

The volcanoes along the chain are not connected. Although they are formed by the same process i.e. subduction at the plate boundary, they do not share the same magma chamber nor are there long conduits. A volcanic eruption on one island, cannot trigger an eruption on another island.

[@cameramon]

@@UWISeismicResearch I'm a Vincy, so you know I am going to question that. Keeping in mind that the Earth is always spinning or turning; so what you're saying is that the magma layer doesn't move? I like to question, that is how u learn.
