Investigating how ๐ eruptions can affect climate projections
Unlike human influences on climate change, which occur slowly & can be accounted for in climate models under a range of socioeconomic scenarios, the sporadic nature of ๐ eruptions poses a challenge for climate projections
Scientists can't currently forecast the occurrence of ๐ eruptions โ incl. when & where they will occur & how much SOโ they will emit

Lava coil (Volcanology ๐)
A lava coil is a spiral or scroll-shaped lava formation occurring when relatively low viscosity lava such as Pahoehoe solidifies along a slow-moving shear zone in the flow. The shear produces a KelvinโHelmholtz instability that forms spiral-shaped patterns. Depending on the side of the flow the spiral is clockwise or anti-clockwise. They have been observed on flows near Kilauea on Hawai'i...

The mountain started to crumble or fissures formed maybe long before humans started messing the atmosphere at a large scale. However, accelerated global warming probably moved the geological clock forward for such an event. This may also be the case earthquakes

Deformation (volcanology) (Volcanology ๐)
In volcanology, deformation refers to the change in the shape of a volcano or the surrounding landscape due to the movement of magma. This can be in the form of inflation, which is a response to pressurization, or deflation, which is a response to depressurization. Inflation is represented by swelling of the ground surface, a volcanic edifice, or a ...

This is in part the work of Robert Bogue, with John Stix & Peter Douglas.
Diffuse CO2 emissions can permeate to the surface and can stimulate plant growth, preceding any deformation, heat, or other warnings of an impending eruption.

Magmatic lull (Volcanology ๐)
A magmatic lull is a period of declined magmatic activity in volcanically active regions. They may occur as a result of underthrusting of hinterland lithosphere beneath a volcanic arc, changes in subduction parameters such as relative velocity, direction and slab dip, arc-arc collisions and subduction hinge advance. Individual magmatic lulls may last tens of millions of years between period...
Volcaniclastics (Volcanology ๐)
Volcaniclastics are geologic materials composed of broken fragments of volcanic rock. These encompass all clastic volcanic materials, regardless of what process fragmented the rock, how it was subsequently transported, what environment it was deposited in, or whether nonvolcanic material is mingled with the volcanic clasts. The United State...

Second earthquake swarm hits Campi Flegrei one day after state of emergency declaration
A new #earthquake swarm began in the Campi Flegrei caldera at 14:23 local time on May 14, 2025, just five hours after Italyโs National Institute of Geophysics and #volcanology (INGV) reported the end of a previous swarm that led to a state of emergency declaration.
