🔥How hot can an intense wildfire get?🔥 Highly graphitic particles in the 2023 Quebec wildfire plume over NY state show that prior estimates may be shy by >>100s °C. Read about it in our collaborative paper with @CornellEng @CornellEAS @PARADIMResearch tinyurl.com/43b3kamh

@MichaelTG09 @obyvatel7 Ze germans have one ready for you. I used to listen to this on tape. youtube.com/playlist?list=…

@obyvatel7 I’m going to make a playlist.

Surface chemistry of volcanic ash particles determined by nanotexture-sensitive fracture focusing during magma fragmentation, modifying the reactive interface and subsequent environmental impacts @LMU_volc @avast_project. nature.com/articles/s4146…

@MichaelTG09 I remember The High King being amazing. I also loved books by Alan Garner - Elidor and The Moon of Gomrath. But my favorite was probably

New paper alert: Our alumnus Adrian Hornby @avast_project has published "Nanoscale silicate melt textures determine volcanic ash surface chemistry" in @NatureComms , the results of laboratory volcanic eruptions and detailed ash particle analysis.

"Fragmentation behavior of young pyroclasts from Mt. Pelée, Martinique." has been published open access. The results of the MSc thesis of @HuebschVolc at @LMU_Volc @LMU_Muenchen. With @CorCima, @avast_project, @AudreyMDubuy, @LDR_Strasbourg doi.org/10.1007/s00445…

Check out our new paper while the ink is still drying - a first global survey of the mineral and glass phases in fine volcanic ash! rdcu.be/dmHAx

I wrote an email to the @royalsociety. Scary to expose myself/my failure like that 😬 Please RT if you think the RS should provide feedbacks to applicants on all of their major funding schemes. 🙏 Has anyone ever tried to write them an open letter to make things change?

@WeAreVolcanica This eruption probably helped push the War Department to request the USGS to investigate Alaskan volcanoes - pubs.usgs.gov/bul/1028a/repo…. My grandfather organized the initial field studies in 1946. Here he is trekking toward an erupting Okmok with Lt. Ray Wilcox and Sgt. C.D. Clawson

@WadsworthFabian @LMU_Volc Here is Krafla glass for you - what you can see of it. This was also a 800 C experiment, with a salt-crammed surface.

@avast_project @LMU_Volc I see.

1/6 Highlighting doi.org/10.1007/s00445…, where Ana Casas of @LMU_Volc formed CaSO4 salts on glassy ash particles in an ash-gas reactor & I wrote an image-analysis macro to measure them. We think this is the 1st time volcanic salts have been quantified on a single-particle basis.

New Report out now! This team demonstrate that during an eruptive crisis, rapid-response petrology can be a powerful tool to quickly understand the magma feeding the eruption, useful for inferring future changes and as a part of the monitoring arsenal! doi.org/10.30909/vol.0…

@WadsworthFabian @LMU_Volc This one's an Fe-free HPG8 cooked at 800C - showing off the big crystals.

@avast_project @LMU_Volc Krafla glass?

6/6 Did I mention Krafla rhyolite? Find out more about that, experiments in HCl-bearing atmospheres and varying timescales in the paper, and the image analysis routine here github.com/hornbya/Ash-su…. Also, shout out to coauthor Carina, LMU alumnus now MSc student at Freiburg.

5/6 We compare results from image analysis to those from leachate, the standard method. We find good agreement for synthetic samples, but not for the largest salts formed on natural Krafla rhyolite, possibly due to a simple shape model for the salts. Something to improve on!

We are a #DiamondOpenAccess journal for peer-reviewed volcanology. A lot has changed since we conceived our publishing project in 2016, and we're changing too, continuing to innovate and introduce new features and policies to improve our journal platform! youtube.com/watch?v=a73h9j…
