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 go.nature.com/4hIZ8Ma

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?🤔

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! 😁 jvolcanica.org/ojs/index.php…
In the name of shameless self-promotion, the paper it’s from can be found here for those who may be interested 🙂 link.springer.com/article/10…

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!
Our new cover for Vol. 6 Issue 2 is live!

🚨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. tinyurl.com/29c6ebxc & tinyurl.com/mpd7tphh

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 – at Wellington Region, New Zealand
Simon Barker retweeted
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 ⚒️ – at White Island, Bay of Plenty Region
Simon Barker retweeted
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! – at Thames-Coromandel, New Zealand
Simon Barker retweeted
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 🌋 – at White Island, Bay of Plenty Region

Ash found buried deep in Antarctic ice has highlighted the massive eruptive power of our best-known super-volcano - while also helping scientists refine the date of Taupō's most recent big blow nzherald.co.nz/nz/ash-buried…

Some 1800 yrs ago, this little guy travelled 5000km from NZL #Aotearoa to Roosevelt Island #Antarctica. The age of the ice containing the Taupō #tephra is consistent with the age obtained from trees killed by the🌋. Paper led by Stephen Piva @VolcanoSimon
