A mystery eruption, solved?

Uncovering an eruption that caused global temperatures to drop took geologic detective work.

New research from @WillHutchGeo @univofstandrews, comments from Katharine Cashman @uoregon, story by @KatherineKornei.

The next massive volcano eruption will cause climate chaos — and we are unprepared https://t.co/OZoZykrHUM

Great @nzherald article highlighting the findings from our new research.

New eruption on Reykjanes, Iceland started around 2 pm local time. The fissure is in the same place as the previous eruption, a few km north of Grindavik. Currently ~2.5 km long and may be still lengthening

📣Many prolonged cold periods similar to the Little Ice Age occurred during the Holocene as a result of #volcanic activity through gradual ocean-sea ice feedbacks.

How can electrical conductivity help us locate magma? Or how do seabed sediments provide a window into past eruptions?🤔

Thanks to @cconcannonsci for putting together this fantastic piece on RNZ’s Our Changing World series that covers the wonderful PhD work of @GrechLicari and our current research around Tūhua and Whakaari volcanoes. @gnsscience @VicUniWgtn

New paper! How accurate are hindcasts of explosive eruptions? In this new work from Stix et al, these authors assess the use of tremor as an eruption forecasting tool. More here 👇

One of my paper figures made the cover of @WeAreVolcanica! 😁 https://t.co/gRcE0aWtfs

In the name of shameless self-promotion, the paper it’s from can be found here for those who may be interested 🙂 https://t.co/ggGRAWfQho

[Volcanica @WeAreVolcanica]

This cover design is thanks to Dr Hannah Elms who has beautifully imaged a ~100 micron diameter, quartz-hosted rhyolite melt inclusion from the 1314 CE Kaharoa eruption, from Mt. Tarawera, Ōkataina Caldera (in the Taupō Volcanic Zone of New Zealand). We love it!

🚨2 geochemistry positions 🚨
in beautiful @univofstandrews (1 postdoc, 1 lab tech) studying volcanic forcing of climate. FWIW I am definitely better at science & supervising than social media!👩🏻‍🔬 Deadline extended Jan 10. https://t.co/aIpgLRDX6h & https://t.co/XMiTLyVUTz

[Simon Barker @VolcanoSimon]

I am so stoked to have been awarded a Rutherford Discovery Fellowship. Looking forward to working with some amazing people over the next 5 years to understand the processes that drive New Zealand’s volcanoes. 🌋

[Royal Society Te Apārangi @royalsocietynz]

In its final year, the Rutherford Discovery Fellowship has awarded 12 outstanding recipients with $800,000 each over the next five years to carry out their specialist research programme.

Time's flown by on the #BeneaththeWaves #TAN2315 voyage. After several days of #core collection, cool #tephra sampling and beautiful views of #Tuhua & #Whakaari, we're stepping off the #RVTangaroa with 105m of cores! Thanks to all involved, it was a blast! #PhD #womeninSTEM

[Simon Barker @VolcanoSimon]

A game of cores. Plenty of cores + tephra = happy student ⁦@GrechLicari⁩ #whakaari #tuhua 🌋

[Jacqueline Grech Licari @GrechLicari]

Today was a big day for the #TAN2315 coring team. Despite difficult subsurface conditions around #Whakaari, we retrieved 6 usable cores! We also opened #Tuhua's 1st core & observed at least 6 #tephra layers, which were sampled for more onshore analyses. More to follow tomorrow ⚒️

[Jacqueline Grech Licari @GrechLicari]

Today we carried out the 1st coring of the #TAN2315 trip. We recovered 6 cores around #Tuhua (Mayor Island), with one reaching a whopping 5.4m in length! We even spotted tephra around a few of them. Super excited for tomorrow when we get our first sneak peak into the split cores!

[Jacqueline Grech Licari @GrechLicari]

Day 2 of the #TAN2315 trip saw us setting up labs and revising field plans. Today (Day 3), the real #science began with the deployment of #magnetotulleric (MT) stations around #Whakaari. We're now approaching #Tuhua, where piston #coring for my #PhD will replace MT around 3am 🌋

[Simon Barker @VolcanoSimon]

This is going to be an epic trip to the Bay of Plenty volcanoes. Can’t wait to see what we find for Jacquelines’s PhD project! @MBIEsci @VicUniWgtn @gnsscience

[Jacqueline Grech Licari @GrechLicari]

This morning, 12 scientists including myself, boarded the #RVTangaroa in #NZ for the #TAN2315 expedition funded by 'Beneath the Waves' to study the eruptive histories of #Whakaari & #Tuhua via marine coring & MT measurements. Excited for what lies ahead! 🌋 #PhD #volcanology
