Our latest paper is out! We use the Southern Volcanic Zone as a natural laboratory to assess the impact of loading and unloading of ~2 km thick Patagonian ice sheet on magma plumbing systems. As G.R.R. Martin would say: Ice and Fire!!🌋🗻🧊 https://t.co/BOCQw3zHed

I'm recruiting a graduate student to work in the magma processes lab @LehighU For more details on the project and how to apply, see the position advertisement here: https://t.co/Gz6kFFBkah

Lava flowing from new vent system in this ongoing eruption on #Kilauea's middle East Rift Zone. Lava flowing downslope to brink of Nāpau Crater in channel more than 50 m (about 164 ft) wide, pouring over western cliffs to create lava falls. #HVO overflight video from Sep 19.

🌋🚨Volcano paper alert @GSAPublications! Our new 40Ar/39Ar + 3He ages and magma compositions on Mocho-Choshuenco show an interesting behavior of the volcanic complex before, during, and following the Last Glacial Maximum. See here https://t.co/U8bM30m4p4

Interested in the effect (or lack thereof) of CO2 on magma chamber dynamics? PhD candidate Kate Scholz just published her work about this here: https://t.co/yFbB155SQQ Congrats, Kate!

@Tuff_Cookie @volcano_diana 😭😭😭

@geo_lissie I'm soooo jealous 😭 but SO glad you all got to Rotorua before the floods! Be safe and HAVE FUN!

Throwing the towel in on trying to make it to New Zealand and hereby declaring myself (and my poor husband and 9-month-old baby who I dragged with me) officially #IAVCEIstranded in a hotel airport at SFO

Last week we wrapped up the Volcano-Ice Summer Program (VISP) at Volcán Llaima, Chile with students from Universidad de la Frontera!

[Meredith Townsend @townsendmr]

Thanks @ErinScott_geo for the highlight!

[Nature Reviews Earth & Environment 🌈 @NatRevEarthEnv]

New Research Highlight!

An article by @townsendmr & Mong-Han Huang found that Kīlauea’s destructive volcanic flank eruption in 2018 was likely fed by multiple magma chambers

@Penny_Wieser @VolcanoInSAR @Mongulator We could look at the later stages, though it is more complicated with the caldera collapses. Lots of neat work has been done relating summit dynamics to lava effusion during later stages (e.g. https://t.co/l4RapSoHoA) though not resolving how the S. Caldera reservoir was involved

[Meredith Townsend @townsendmr]

Dynamic magma transport models suggest that rupture of the shallow East Rift Zone reservoir fed the 2018 dike intrusion at Kīlauea and buffered pressure at the summit. My paper with @Mongulator in JGR Solid Earth is out now! https://t.co/Q7InT0iy3E

If you are at #AGU2022, feel free to stop by my talk on Monday at 11:10 AM CT (Session V13A-02). I will be showing how magma storage evolution is potentially influenced by ice loading/unloading on a continental arc volcano (Mocho-Choshuenco)

[Meredith Townsend @townsendmr]

Hey, that's my advisee!! 🤩🌋💪

Meet Gui Aksit She/They, @guiologist a Ph.D. student at University of Oregon. Her research focuses on silicic dike propagation at the eroded Summer Coon volcano in Colorado. She studies the physical properties preserved in chilled dike margins
