At 11,973 feet above sea level, Sierra Blanca is the tallest peak in the Sacramento Mountains, with spectacular views of the lower peaks and the Tularosa Basin. From the peak you can see where the black lava flows of Valley of Fire stops right before the dunes of White Sands begins. Stark contrast.
Most of the Sacramento Mountains are limestone. Sierra Blanca is the sole volcano.

@History_of_Geology very fascinating aspect of the #lunar #Apollo17 mission to have found indications of early #volcanic #activities in form of glass remnants.

The #Volcanic Isles . A brief history of volcanism across The British Isles.
Quite pleased with how this one turned out.
Location of volcanoes taken from wikipedia (spotted a mistake and got to make an edit to wikipedia in the process); fault lines from the #BGS 625k bedrock dataset and the IE GSI 500k Bedrock Geology for Ireland. Font: League-Spartan by the League of Moveable Type.
#requests, #pandas and #geopandas for scraping and wrangling.#scipy for making the proximity surface (that's the colour scheme), #matplotlib for plotting. With all labeling done manually in #inkscape.
EDIT: I've been kindly and helpfully informed that (a) Ben Nevis' age is closer to 399 Ma; (b) some are missing; (c) others perhaps shouldn't be there; (d) it's complicated. So, maybe don't use this map to make any strategic decisions.

Scientist makes groundbreaking discovery while studying ancient Roman technique for concrete: 'We have a huge potential'
by Calvin Coffee
Sun, August 31, 2025"Concrete has a massive carbon footprint. One researcher from the University of Auckland is working to reduce it by studying ancient #Roman techniques. Using natural volcanic materials and industrial byproducts, he's incorporating #pumice and #seashells to create an #EcoFriendly, traditional alternative.
"At the Structures Testing Laboratory in Newmarket, New Zealand, Enrique Del Rey Castillo blends volcanic ash and kaimoana shells as replacements in the cement-making process, leveraging their #SelfHealing properties, which can repair cracks over time through natural chemical reactions.
"This initiative is crucial, as concrete is one of the world's most polluting materials, with global cement production accounting for 8% of total carbon emissions, contributing to rising global temperatures and increasing health risks.
"Del Rey Castillo has spent years testing how local materials can serve as sustainable alternatives. After focusing on conventional substitutes such as fly ash, he shifted to natural materials available nearby.
" 'I realised we have a huge potential in New Zealand with the use of natural #volcanic materials and #byproducts of primary industries,' Del Rey Castillo said.
"Concrete is essential for constructing bridges, roads, dams, and buildings, but its production releases over 4 billion tons of carbon dioxide annually. Calcining cement-primary materials at 1,500 degrees Celsius in a kiln emits large amounts of carbon dioxide and produces chemical reactions. Each pound of concrete releases 0.93 pounds of carbon dioxide.
"Pumice, however, doesn't require the energy-intensive calcining process; it just needs to be dried at 100 degrees Celsius to remove moisture before being ground into a fine powder. 'The carbon footprint is about 8-10% of the carbon footprint of cement,' Del Rey Castillo explained."

Researchers Discover Five New #HydrothermalVents in Pacific Ocean https://www.sci.news/othersciences/geoscience/east-pacific-rise-hydrothermal-vents-12799.html
"#Hydrothermal vents are rich in chemicals that supply energy to #animal life, fueling rich and productive #ecosystems. The new sites... are located on the #EastPacificRise near 10°N latitude, a part of the globe-spanning mid-ocean ridge #volcanic mountain chain, where two #TectonicPlates are splitting apart at a rate of about 11 cm per year."
