🧪🌋🌊 Deep-sea volcanic pyroclast formation decoded. Most submarine eruptions don't break the sea surface & are rarely observed. We're uncovering how energetic underwater eruptions produce distinctive fragmental deposits unlike subaerial plumes. 2 modes shown here presented at #AGU25. More in ALT text

Glowing molten ejecta and freshly formed pyroclasts from a submarine volcanic eruption. Two distinct , mildly energetic eruption styles are shown at nearby vents during the 2009 West Mata eruption in northern Tonga. These common but rarely observed fully underwater eruptions produce thick, coarse pyroclastic deposits close to the vent. The deposits are unlike less frequent, but dramatic, very energetic, and more often observed eruptions that break the sea surface, such as Hunga Tonga–Hunga Haʻapai in 2022 or Havre in 2012, with eruption plumes and deposits influenced by distribution all or partly in air. Such eruptions that occur entirely beneath the sea surface produced landforms with low sea bed volcanic terrain stability, impacting the geology, hydrothermal activity, and ecosystem development.

🧪🌋⚒️ This never gets boring. A pulse of hot lava meanders down the vent proximal surface flow this morning at Kilauea volcano #Hawaii. More than just pretty, Volcanologists study time variations of lava, tephra & gas distribution, movement, & composition to understand volcanic processes and hazards

🧪🌋 What does one of the Kilauea #Volcano active vents look like between dramatic high fountaining eruption episodes happening roughly weekly in 2025? At night, you can see the conduit is a fuming, glowing-orange hole in the ground with magma 100s of m beneath the surface, waiting to repressurize.

West Mata 🌋 shots 4 #FieldPhotoFriday, described in ALT text. AI calls me an “Oceanographer 🌊 passionate about volcanoes, deep-sea science 🧪, community engagement & inclusivity,” then asks: “Are volcanoes just angry mountains? Is the government hiding underwater volcanic alien civilizations?” Hmm 😜!

Annotated views from my research on submarine volcanic eruption and eruption products at West Mata volcano, Tonga, showing a few of the many styles of activity we see at this small yet very active volcano, and a current image of me :) Sources for all images: Kenna Harmony Rubin

🧪🌋⚒️Hawai‘i’s Pele is at it again! #Kilauea #Volcano Episode 33 began on Sep 17 & overnight brought low fountaining & lava overtopping the vent. Live frame grabs from USGS webcams 3 AM HST 18 Sep 25. Ongoing eruption started Dec 2024 & has periodic day-long pulses. Cam locations & link in ALT text.

🧪🌊 Last week's joyous pre-semester selfies + some science 😉 40 yrs of university teaching, leadership & peer-reviewed research in topics like volcanology, deep-sea, coral reef, & environmental chemistry, taught me that girly scientists can be trusted academicians 🏳️‍⚧️, even in a world of so much hate.

A fun post with some of Kenna Rubin's recent outfits and research: A. on the sides: 2 pictures of the girl scientist from 28 Aug & 29 Aug 2025, trying to decide if it is still summer, or early autumn in New England. B. In the center (1) Tall, thin, spindly black smoker chimneys emit unusual fluids at Earth’s deepest known hydrothermal vent field, 5000m below sea level (2) Alvin samples a hydrothermal vent site 2500m deep on the East Pacific Rise; (3) Hawaii's Kilauea volcano erupting at night, as seen from the USGS V2cam, at 5:29 AM HST 22 April 2025; (4) ROV Subastian sampling arm taking specimen of a large Ice Age coral head at 150m depth in Hawaii. on Schmidt Ocean Institute #SeaLevelSecrets Expedition.
