Ashes in the archive.
Lake Chalco holds a 400,000-year record of 450+ explosive eruptions near Mexico City—some leaving >10 cm of ash. What does this mean for volcanic risk today?

Our new paper published in #MarineGeology contains new geophysical data and rock samples collected during the #M191 research cruise in the #Sicilian #Channel. New #submarine #volcanoes were also discovered!🌋You read all about it here:

Geophysical data and samples from the M191 cruise have reshaped our understanding of submarine volcanism in the Sicilian Channel, revealing new volcanoes. Read all about it here:

Our paper, showing how Icelandic granites are not a good analogue for formation of our first continents, but may be useful for silicic rocks on planets without plate tectonics is out today in @CommsEarth

@subglacial @HubGeology @HTuffen Just seen this after being in the Lake District teaching in the field! 🗺 Looks like better weather at Thórólfsfell than the Lakes at the moment 😉

@CharlotteMBird @unibirmingham @VirtualPalaeo @JamesWheeley @PalaeoStephan @LukeEMeade Congratulations, Dr Bird! Very well deserved!

📢🌋SO excited for the next Ashvances in Tephra Seminar (monday march 25, 1600UTC)! Lucky to have @Sole_Osores (@SMN_Argentina) & Federica Pardini (@INGVvulcani) 🤩 Two fantastic speakers leading tephra research & operational response. Registration👉 https://t.co/fS0Jtlh2Dw

Article: Early continental crust formed at depth, implying some type of plate tectonics operating as long as four billion years ago

@PaulSpeak4 Thanks, @PaulSpeak4 It was great to finally meet you and I am delighted you enjoyed my talk on Thorolfsfell. It was brilliant to hear your thoughts too 😊 I really enjoyed giving the @OpenUniGeolSoc Geoff Brown Lecture and many thanks to @subglacial for suggesting me for this!

[Dr Alastair Hodgetts @MagmaticAl]

Thanks to the @OpenUniGeolSoc for inviting me to give the Geoff Brown Lecture 🌋 at their annual #symposium this weekend! It was a fantastic few days of #geology and great fun to talk about my research to such an enthusiastic community of #earth #scientists! 🪨 🔨 🌎

Kalws hrthame in Greece 🇬🇷! Our 2.5 day transit was spent dismantling equipment, presenting preliminary results on #SUAVE to different groups onboard and working on leaving our mark in the #RVMeteor guestbook. Science team has only a few hours left together now! #M191 out!

[Jacqueline Grech Licari @GrechLicari]

And that’s a wrap! Final dredge of #M191 is on deck and processed, now to start our transit to Greece ⛴️🇬🇷

[Jacqueline Grech Licari @GrechLicari]

As the #M191 dredge team processes sampled rocks, shift leaders operate from the bridge alongside #RVMeteor's nautical crew, shown below selecting and directing dredge locations🌋⛴️ #SUAVE

[Jacqueline Grech Licari @GrechLicari]

On #RVMeteor we like to keep things interesting: if not dredging/mapping, you can find us doing #scicomm. Chief scientist Jörg Geldmacher introduced our work to the crew. Also, a blog post reviewing our discoveries from the first week at sea is now live: https://t.co/UpLun9Wwmb

[Dr Alastair Hodgetts @MagmaticAl]

Excited to be working with David Zhang (@jzhang_volc) et al on this exciting #Icelandic eruption 🌋 #Hrafntinnuhraun has produced some intriguing pyroclastics which I'm sure we will know much more about soon ⚒️🪨 Make sure to follow David, @subglacial, @HTuffen and @hollyeunwin

[Jacqueline Grech Licari @GrechLicari]

Yesterday, we discovered the coolest rock of the cruise so far! 🪨 Our igneous petrology teams immediately got working to figure out what processes could have led to its formation. Can you guess what it might be?

[Jacqueline Grech Licari @GrechLicari]

On #M191 #seafloor #mapping helps determine dredge locations. The MBES provides bathymetric data & the magnetometer identifies ferromagnetic features (intrusions, seamounts). New volcanic features were found (below) & some suspected volcanic edifices turned out not to be igneous.

[Jacqueline Grech Licari @GrechLicari]

Honoured to be working with such a passionate team of scientists, excited by our results and ready to help me with creating blog content! 🌋🐚 @MicallefAaron @kerysmeredew @MagmaticAl @jakob_lang @geologybham @ogs_it @UMmalta @GeosciencesEd @WellingtonUni @UniofOxford @GEOMAR_de
