  1. Mirabilite Mounds at Great Salt Lake

    In cold weather, a new geological feature has shown up at Utah’s Great Salt Lake in the last decade. These salty mirabilite mounds form terraced crystals that resemble Yellowstone’s Mammoth Hot Springs.

    Diagram showing how a salt-laden spring pushing upward through the mirabilite layer can then form mounds at the surface when the dissolved mirabilite recrystallizes after the water evaporates.

    Mirabilite is hydrated sodium sulfate (as opposed to the sodium chloride of table salt). The structures form when upwelling spring water partially dissolves the layer of mirabilite found beneath the lake bed. That sulfate-laden water rises to the surface, where it freezes into the crystals seen here.

    A timelapse showing the formation of mirabilite mounds.

    When temperatures rise above freezing, the water in the mirabilite evaporates, leaving behind white, powdery thenardite. (Video credit: Great Salt Lake Institute; image credit: Utah Geological Survey)

  5. The Disappearing Great Salt Lake

    Since 1989, Utah’s Great Salt Lake has lost some 70% of its surface area. The exposed lakebed left behind is a source of toxic dust that gets lifted into the air. Researchers are trying to understand what water sources exist beneath the lake and whether they might save the saline lake and its ecosystem from disappearing entirely.

    A recent study pinpoints underground water by measuring the electrical resistance between electrodes placed meters apart in the ground (photo above). Because salty water is more electrically conductive than fresh water, the researchers can distinguish between them. So far, they’ve found quite a lot of fresh water, sometimes only a couple meters below the surface. But those patches are often quite close to saline water, too.

    The group also described to Eos that they found mounds of invasive reeds lying atop concentrations of fresh water. The invasive species seems to be sucking up water that would otherwise feed back into the lake or support native plants that provide habitat to native birds. (Image credit: M. Thorne; research credit: M. Jacketta et al.; via Eos)

    The Irish National Seismic Network

    The Geophysics Section of DIAS operates the Irish National Seismic Network (INSN). Established in 1980, the network monitors seismic activity across Ireland - through a series of stations. Seismic data is transmitted in real time to the INSN data centre at 5 Merrion Square and shared internationally.

  19. Earth, Sweet Earth ( Science For Everyone) by Ekaterina Radkevich

    The book is based on the author’s impressions of her numerous expeditions in the many countries. It is a fascinating narrative rather than a mere record of facts irrespective of how scientifically valid they can be. The book is bound to be appreciated as a piece of absorbing reading by anyone who cares to increase the scope of his or her competence about our sweet home of a planet that must be saved from destruction at all costs.

    Ekaterina Radkevich, Corresponding Member of the USSR Academy of Sciences, is one of the most distinguished geologists whose works are well known in her own country and in many other parts of the world. The overwhelming success of her publications is chiefly due to her indefatigable practical activity in the USSR and elsewhere and her unflagging interest in theoretical research which she has been conducting for quite some time at the Institute of Geological Studies in the Far East (Viadivostok).

    Note: This book was the last remaining volume in the Science for Everyone Series! This completes volume the SFE series in English.

    Many, many thanks to Hassaan Ali who purchased and posted this book to us to complete  this series. Much appreciated help!

  24. The rate-mismatch hypothesis posits that global mass extinctions occur when the pace of environmental change outstrips the rate at which biological life can undergo evolutionary adaptation. It provides a mathematical model linking Earth's historic extinction events to the critical disparities between environmental shifts and species' adaptive capabilities.

  33. Retreating Glaciers Risk Tsunamis

    On 10 August 2025, the slopes of Alaska’s Tracy Arm Fjord gave way, sliding into the water. The resulting tsunami was the second-largest ever recorded, with a 481-meter runup after a 100-meter initial wave that moved at more than 70 meters per second. The fjord was fortunately empty at the time, though it is regularly visited by cruise ships. After the landslide, a seiche ricocheted through the fjord for 36 hours.

    With no earthquake to trigger the tsunami, researchers had to piece together the accident through forensics. Their study concluded that the glacier’s retreat had left unstable slopes exposed, likening it to a child’s closet overstuffed with hastily gathered toys. The moment the door is no longer held closed, everything comes crashing out.

    Ultimately, the landslide-induced tsunami is, therefore, a result of climate change. That result is disconcerting, given the increasing frequency of cruise ships visiting glacial fjords. Unlike earthquake-induced tsunamis, landslide-induced ones like the Tracy Arm event don’t come with a seismic warning. With rapid climate change and frequent tourism, risk management is critical.

  39. Asteroid bombardment during the Earth's formative eons fractured the upper crust, generating extensive, high-permeability hydrothermal systems that established the geochemical environments necessary for the emergence of life.

    On the other side, geologists point directly to the infallible record in the rock strata. They argue that the planet's thermostat is moving too fast, waking sleeping geophysical giants—from ocean conveyor collapse to magnitude-eight post-glacial megaquakes.

    Because when the velocity of change pushes a system past its breaking point, the support stones are washed away. And as the rock record shows us... the Earth does not negotiate.

    In today’s episode, we are diving into a fierce academic debate that completely strips away our human hubris: Can modern civilization survive the sheer velocity of current climate change? On one side, historians argue that human ingenuity is an unmatchable force—that we are evolutionary bottleneck survivors who can engineer our way out of any corner.

    Our entire modern world—our mega-cities, our massive global supply chains, our rigidly optimized agricultural zones feeding eight billion people—is that colossal boulder. It seems permanent. It feels immovable.

    But it is balancing on an incredibly narrow, highly specific set of environmental conditions.

    And right now, the system is sliding into deep, systemic instability.
