AC/DC Melbourne Concert Tremors Rock the City: Seismologists Weigh In
Melbourne’s Night of Thunderous Riffs Fans flocked to Melbourne’s arena for a landmark return by AC/DC, the legendary rock icons. The show, held on a brisk Wednesday night, delivered the heavy grooves and thunderous energy fans have long associated with the band. But as the stadium roared, something unusual caught the attention of scientists and…

AC/DC Melbourne Concert Shakes City: Seismic Mystery
Melbourne Roars as AC/DC Returns to Australia When rock legends AC/DC returned to Australia for the first time in a decade, the energy in Melbourne was palpable. Fans packed into the venue, lights flickered, and guitars wailed. But as the opening riffs rolled, something unexpected appeared on a very different kind of meter: seismographs. Local…

Remote Iranian Volcano Awakens: 700,000-Year Silence Ends as Ground Rises
Rising Signals: A Quiet Giant Awakens A remote volcano in southeastern Iran has begun to visibly lift from its long rest, rising about 9 centimeters (roughly 3.5 inches) in just ten months. While this may sound modest, scientists say the movement could signal the early stages of magmatic pressure building beneath the surface. The discovery,…

Deep Earthquake Aftermath: Why Deeper Crust Changes Persist Long After Shaking
New Insights into Post-Seismic Deformation When an earthquake rattles the ground, it often leaves a visible legacy of cracked roads and toppled buildings. But beneath the surface, the story continues. Geologists are increasingly focused on post-seismic deformation—the way the Earth’s crust gradually adjusts to the sudden redistribution of stress after a quake. Recent work from…

Deeper Crust Takes Longer to Heal After an Earthquake, MIT Study Finds
Overview: What post-seismic deformation reveals about the crust Earthquakes are not a one-and-done event. The initial shaking is followed by a period of post-seismic deformation, a time when the surrounding rocks adjust to the sudden changes in stress caused by fault rupture. In this phase, areas that didn’t fracture still experience stress shifts and adapt,…

Deep Earth’s Quiet Aftermath: Why Seismic Healing Persists Longer at Mid- crust Depths
Introduction: The Hidden Timeline of Post-Seismic Deformation Earthquakes grab headlines with dramatic ruptures and surface destruction, but the story of how the Earth settles after a quake runs much deeper. Post-seismic deformation refers to the slow adjustment of rocks around an earthquake as new stresses redistribute after the initial rupture. While society tends to focus…

Like putting on glasses for the first time—how AI improves earthquake detection
Introduction: a quiet revolution in seismology On January 1, 2008, Calipatria, California, recorded a magnitude -0.53 earthquake that most people would never feel. Yet, this tiny event is emblematic of a broader shift: over the past seven years, AI-powered image-like analysis has automated one of seismology’s core tasks—detecting earthquakes. These machine learning tools can identify…

Like putting on glasses for the first time — how AI improves earthquake detection
Intro: A new lens on earthquakes On a quiet January night in 2008, Calipatria, California, registered a tiny earthquake with magnitude -0.53. It was so faint that it went largely unnoticed by residents and seismographs alike—yet its record matters. Over the last seven years, artificial intelligence, especially machine‑learning models trained on large seismogram datasets, has…
