  1. Shiprock from Gallup is a ~1.5-hour drive north on U.S. Highway 491, leading to a striking volcanic neck formation. You can get a closer view or the formation and the dike wall by taking the paved Indian Service Road 13. Access to the base of Shiprock is restricted, so please view from the road or with a permitted tour guide, like Navajo Tours USA.

    Quite pleased with how this one turned out.

    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.

  5. The study indicates that ash from the #Nishinoshima #eruptions was transported by wind and #ocean currents to the waters around #Mukojima, serving as a nutrient source for #phytoplankton growth in that area.
    The findings suggest that volcanic ash can enhance the productivity of #marine waters even at considerable distances from the #volcanic site.

  6. Scientist makes groundbreaking discovery while studying ancient Roman technique for concrete: 'We have a huge potential'

    "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."

    "For more than two decades, the #Shoshone and #Paiute peoples, scientists, #environmentalists, the federal government, Nevada citizens and politicians have wrestled over the fate of Yucca Mountain. The federal government had selected the mountain to become the nation’s primary dumping ground for deadly, high-level #NuclearWaste, but the long-contested project is at last on its way to being closed. Meanwhile, the #WesternShoshone fight off federal efforts to sell their land in order to give multinational #corporations access to its #mineral resources. But the Western Shoshone stand firm. Raymond Yowell, Chief of the Western Shoshone National Council, said, 'Western Shoshone title is still intact… We’ve never accepted their money and never will — our land, the earth mother is not for sale and we will protect her and continue our responsibilities as caretakers under the Creator’s law.'

    The Land and Its People

    "Yucca Mountain is located within the Western Shoshone Nation and has long been a place of powerful spiritual energy for the Shoshone and the Paiute. To the Western Shoshone it is #SnakeMountain, a place with rock rings that transmit prayers to the Great Spirit and messages back to the people. The late Shoshone spiritual leader Corbin Harney told a traditional story that Snake Mountain will one day be awakened and split open, spewing out poison. This prophecy may predict the potential disaster of #volcanic activity and nuclear waste leakage. Shoshone ancestors are buried in the mountain and the water in the area is sacred, as it is with many desert peoples.

    "The 60 million acres of Western Shoshone territory in Nevada, Idaho, Utah and California, which includes Yucca Mountain, was never deeded to the U.S. government. According to the 1863 #RubyValleyTreaty that the Shoshone signed with the government, most of the area now used by the U.S. military for #NuclearWeapons testing and the proposed waste storage site was explicitly recognized as Shoshone land. However, the U.S. government now claims 80 to 90 percent of it, meaning that the Shoshone are unable to control what happens on their ancestral land. Legislators continue to try to persuade the Shoshone to accept financial compensation for this land, which most view as a way to extinguish aboriginal title and preclude future land claims, easing the way for renewed nuclear weapons testing and waste storage, as well as resource #extraction.

    "In the late 1970s government scientists began to study Yucca Mountain as a possible repository for nuclear waste, and since 1987 it has been the only site considered for 77,000 metric tons of spent nuclear fuel and radioactive waste. While the Yucca Mountain Project has been debated, the amount of nuclear waste needing burial has already surpassed what the repository was designed to hold. In the meantime, nuclear waste continues to sit in steel-lined pools or casks near power plants throughout the country that produce 2,000 tons of high-level waste per year. The waste is lethal for 10,000 years and dangerous for 250,000 years."

    [...]

    "The Yucca Mountain Project calls for the highly radioactive nuclear waste to be encased in steel containers and buried deep in the mountain. Since the canisters will last for 1,000 years at most, the dryness of the mountain will have to guarantee against leakage and migration — an assumption that environmentalists and many scientists say is flawed and dangerous. Surface water percolating into the mountain will carry radioactive particles into the water table and render it toxic. This water table currently supplies water to local communities and farming regions that produce food products for the entire country.

    "In 2005, Energy Secretary Samuel Bodman confirmed that internal department e-mails allude to the #falsification of data on how quickly water flows through Yucca Mountain. This revelation caused a federal investigation, and condemnation from Congress triggered the Department of Energy to completely reorganize the project and lay off 500 employees. Robert Hager, attorney for the Western Shoshone, said that the Yucca site would have been disqualified years ago if the true nature of the subterranean water flow was known.

    "With several local #FaultLines and a #volcano nearby, earthquakes make it likely that the mountain will fracture the repository and send even more water to the waste. There are also grave concerns about the safety of transporting nuclear waste over long distances through several U.S. states, particularly in an era of terrorist threats. During the later Bush years, as environmental concerns mounted and citizens from other states grew more leery, the project began to look more and more unlikely."
