🚨🌋 New paper on hydrothermal alteration & permeability at La Soufrière de Guadeloupe!
🔗 doi.org/10.1016/j.jv...
📊 More altered rocks show higher average permeability
🔬 But microstructures reveal alteration reduces permeability
⚠️ Small datasets can be misleading

Phreatic eruptions at Whakaari Volcano driven by hydrothermal mineralisation and magmatic gas input - Communications Earth & Environment Phreatic eruptions at Whakaari volcano are influenced by subsurface pressurisation magnitudes and timescales, which are significantly influenced by hydrothermal mineralisation and magmatic gas input rates, according to 3-dimensional numerical modelling of volcanic hydrothermal systems.

🌋Phreatic eruptions at Whakaari volcano are influenced by subsurface pressurisation magnitudes and timescales, which in turn are significantly influenced by hydrothermal mineralisation and magmatic gas input rates.

Samples of hyaloclastite from Krafla in Iceland 🇮🇸 🌋 These samples are from different depths within the shallow reservoir, and they’re now ready for some physical and mechanical probing in the laboratory!

Come join us!

Part of our international team of volcanologists working with @rottnrock.bsky.social! From England, Indonesia, and Chile! 🇬🇧 🇮🇩 🇨🇱
Interesting fact: we all like cats! 🐈

Early morning start for our @rottnrock.bsky.social trip to Anak Krakatau from Anyer 🌋 Our luxury speed boats await! 🛥️ 1/9

At Galunggung in Indonesia 🇮🇩 🌋 the @rottnrock.bsky.social team were investigating the impressive recent collapse within the crater - we found plenty of altered rocks in the blocky deposit!

The @rottnrock.bsky.social team were at Galunggung today, a volcano famous after a British Airways flight accidentally flew through the huge eruption plume of the 1982 eruption! We’ll go back tomorrow to investigate, collect rocks, and drone the volcano 🌋

A two part feature!
Lectures and scientific discussions today at the Fakultas Teknik Geologi at Universitas Padjadjaran and the Politeknik Geologi & Pertambangan AGP! 🌋

The @rottnrock.bsky.social team are in Indonesia! 🇮🇩 🌋 we’re here, obviously, to look at the altered volcanoes! 👀 first stop, Tangkuban Perahu in Bandung!

Plenty of altered lapilli tuffs on Cracked Mountain! 🌋🇨🇦

Cristobalite and diktytaxitic textures are common in lavas. Do they influence rock properties? We try to answer this question by measuring rocks from submarine volcano Havre 🌋
