Not sure if the answers I'm looking for are out there in a compact form, but I figured I can ask here.

It also gives you a chance to shine.

What is going on with the Kīlauea volcano? As a layman, magma rose up in the crater, the resulting fluidic pressure (plus other geological factors) caused cracks on the east side creating vents and lava flows.

It looks like there is no magma in the crater anymore and the sides of the crater are slowly caving in. Not to say that Kīlauea will never have magma in it again, but is this the beginning of the movement of the mantle 'hot spot' with a possible new crater forming in the Puna area? If a significant portion of the crater wall collapses into the throat, is there a chance of a future violent event if the magma returns?

I've been watching the USGS YouTube updates, which are just that, updates. I try to avoid other channels as clickbait (running USGS footage as their own, or sensationalism of doomsday scenarios). I know volcanology isn't an exact science, but I'm curious as to a concise explanation of what's going on and what is a possible future scenario.


Vulcanologist or Volcanologist?

Here's a really good and basic summary of volcanoes: https://www.zmescience.com/other/sci...es-of-volcano/

But basically, the Hawaiian volcanoes are shield volcanoes, and -- generally -- shield volcanoes do not experience pyroclastic eruptions.

You're perceptive about hot spots. That's what the Hawaiian Islands are...a series of hot spots.
