An important vote for volcanologists/IAVCEI members that you might have missed (see page 49 in Newsletter), about a "proposal change to allow a president to run for multiple terms of office" Vote here: www.iavceivolcano.org/proposal-cha...

New paper: Led by newly-awarded Dr, Anna Brookfield (& her first paper!): 'Magmatic volatile content and the overpressure ‘sweet spot’: implications for volcanic eruption triggering and style': authors.elsevier.com/a/1i2ys1LkU3...

This paper could have been much longer and there's some things we don't cover in as much detail as we would have liked, but it serves as first discussion of this notion in volcanology, should we ever decide to go down this route in decades/centuries to come. END

If volcano geoneringering ever becomes a discipline, we lay out some guiding principles, slightly adapting the 'Oxford principles' from Climate geoengineering.

There are many ethical considerations, such as uncertainty, justice and equality, risk communication, acts-omission asymmetry, biodiverity, miltary uses, safety, culture and governance we all cover in the paper. shorturl.at/DXYZ5 e.g.

Lasty, the consistent threat of volcanoes, esp large eruptions (1 in 6 per century) that pose global catastrophic risks, means the question of whether we can intervene will keep arising. We support a proactive and informed debate before society tries anything in an emergency.

Also, increased research on solar radiation management, means that our our understanding of the stratosphere and how to manipulate it is likely to increase, especially should we want to reverse any stratospheric injections. E.g. 2nd type of volc geoengineering we outline (below)

There's even been various propositions of bombing volcanoes to use as weapons during the 2nd world war! Both from the US side (Mt Fuji, Japan) and the UK (bombing Mt Vesuvius) see MPs discussing this.

1) We've done it before, see figure 1 via multiple ways throughout history. This includes, bombing lava flow channels, draining crater lakes, cooling lavas with seawater, degassing volcanic lakes and accidential drilling into magma chambers at least 5 times.

It might seem it a little sci-fi, but we note two things: 1) Humanity has done it in various ways before (both intentional and inadvertent) and 2) we think it will become increasing likely to occur in the future.

Volcano engineering is the practice of altering the state of volcanic systems and/or volcanic eruptions to exploit them or mitigate their risk. Maniplation of environmental hazards to mitigate their risk is commonplace, but rarely discussed for volcanoes.
