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 🌋

Volcano thread! 🌋🧵
On the Drake Passage, between the tip of South America and the South Shetland Islands of Antarctica, there is a small island. The island is the caldera of an active volcano, eerily called Deception Island on account of its "outward deceptive appearance as a normal island" 🌋 1/6

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 🌋
