Hello 🌋! @iavcei.bsky.social #ECRNet posting about #Earlycareer #volcanology events and career support!

Colección del equipo necesario para el muestreo paleomagnético de un afloramiento de un depósito volcánico.

El equipo necesario para este tipo de muestreo generalmente no es técnico ni caro. Así, es muestreo se puede hacer en cualquier momento en que hay necesidad o interés, por ejemplo, de nuevos depósitos de un erupción muy reciente (ya cuando es seguro acercarse).

Diagrama que explica los pasos de muestreo para tomar muestras paleomagnéticos de un afloramiento de depósito piroclástico.

La guía se enfoca en el muestreo de depósitos piroclásticos para estudios paleomagnéticos: equipo básico necesario, pasos para seguir en el afloramiento, etc. Esperamos que sería útil para brindar colaboraciones entre laboratorios paleomagnéticos y observatorios volcanológicos.

Collection of equipment necessary to undertake paleomagnetic sampling of volcanic deposits.

The equipment necessary for this type of sampling is generally not especially technical or expensive. As such, it can be conducted any time there is need or interest, for example, from new deposits of a recent eruption (once it is safe to approach).

Flowchart of how to take paleomagnetic samples at an outcrop of a pyroclastic deposit.

The guide focuses on the practicalities of how to sample pyroclastic deposits for paleomagnetic studies: basic equipment necessary, steps to take at the outcrop, etc. We hope it will be useful for building collaborations between paleomagnetic laboratories and observatories.

Nueva preimpresión! Una guía para el muestreo paleomagnético en volcanes activos, para el uso por observatorios volcanológicos. Para publicación bilingüe español/inglés. Esperamos recibir buenas retroalimentanciones para hacerlo lo más util posible! Échalo un vistazo!

New preprint! A guide for paleomagnetic sampling at active volcanoes, for use by volcano observatories! Hoping for some good feedback to make it as useful as possible. This will be a fully bilingual Spanish/English publication to allow for broader use. Have a look!

Good news: a grant I submitted got selected for an interview out of ~150 apps. Only 2 others got interviews!

Bad news: @skypeascientist.bsky.social was not selected in the end 😞

I will keep trying.

In the meantime, consider supporting our work with $5-10/month?

Fieldwork on Volcán de Fuego - British Geological Survey Understanding how one of the world’s most active volcanoes builds up material, and how they collapse to feed hot flows

Cool blog post by @smakris.bsky.social on a super collaborative project to learn more about eruptions and pyroclastic density currents at Volcán de Fuego in Guatemala. Was great to join in the field--now looking forward to helping with paleomagnetic analyses soon!

Multilingual social media analysis reveals global patterns and language imbalances in volcanic eruption coverage - Communications Earth & Environment Social media discourse reflects public engagement with volcanic hazard, but English is the dominant language even in non-English speaking regions, according to a four-year-long longitudinal study across 18 languages on /Twitter.

Check out more insights in the paper ☛ doi.org/10.1038/s432...
Feel free to get in touch with any questions, or if you are interested in communicating volcanology across languages, or if you want to work with a mountain of social media data…

~fin~

Once upon a time, the platform formerly known as Twitter was a vibrant meeting-place where scientists, the public, official orgs and more besides could exchange knowledge. I set out to find out how effective it could be for disseminating geoscience info

The Alaska Division of Geological & Geophysical Surveys is hiring a volcanologist who would work with the Alaska Volcano Observatory. A fantastic opportunity to work with great people and study very active volcanoes. Details in link below. Applications close on Oct. 1. ⚒️🌋🧪 bit.ly/3IkqN9n

Geopeople (of any discipline)! What are your favorite or most useful phone/tablet apps to use in the field? I'm teaching about field tools and methods and want to present some modern alternatives/complements to traditional equipment! Or if anyone has ever seen a list of such apps, let me know!

Back from fieldwork in Guatemala looking at PDC deposits from Fuego for our @ukri.org project exploring generation mechanisms. We had a great time in the field as a team bringing together many skills and experiences. Excited to continue working on this also with those who weren’t in the field!

Aloha folks! I am on the IAVCEI advisory board and welcome comments you’d like me to anonymously pass along to the executive committee about your #IAVCEI2025 experience (both positive and negative). Having concrete feedback is one of the best ways to ensure each experience is better than the last.

Come check out my #IAVCEI2025 poster tomorrow afternoon (1.7.12; poster 25) to chat about complex supereruption plumbing systems and deep rhyolites!

A little bit of news, as of last week I started as an assistant professor at the IPICYT (Instituto Potosino de Investigación Científica y Tecnología) in San Luis Potosí. Looking forward to getting to work with new people here and keep working with all the awesome people who helped me get here!

I’ve worked in an all male science department for 10 years and in my experience, the men don’t even know they’re doing it. (This is not an excuse by the way, just an explanation of what I’ve observed.)

Here’s what I have experienced and witnessed:

This proposed budget is a policy statement, not an appropriation.
There are still a lot of steps and potential changes ahead before it becomes one. This is not a time to sit quietly, team. Let's go.
