      Researchers have developed an algorithm that for the first time can describe a gravitational signal caused by earthquakes with high accuracy. Tests with data from the 2011 earthquake near Fukushima ...

      Upper-Plate Earthquakes Caused Uplift Along New Zealand's Northern Hikurangi Margin

      Earthquakes along a complex series of faults in the upper plate of New Zealand's northern Hikurangi Subduction Margin were responsible for coastal uplift in the region, according to a new ...

      Seismic Biomarkers in Japan Trench Fault Zone Reveal History of Large Earthquakes

      Researchers used a novel technique to study the faults in the Japan Trench, the subduction zone where the magnitude 9.1 Tohoku-Oki earthquake struck in 2011. Their findings reveal a long history of ...

      Slow-Motion Interplate Slip Detected in the Nankai Trough Near Japan

      Huge Tsunami Hit Oman 1,000 Years Ago

      15-meter high waves that pushed boulders the weight of a Leopard tank inland: This is more or less how one can imagine the tsunami that hit the coast of today's Sultanate of Oman about 1,000 ...

      Fault-Slip: AI to Simulate Tectonic Plate Deformation

      Scientists have transformed the UNICORN computing code into an AI-like algorithm to more quickly simulate tectonic plate deformation due to a phenomenon called a ''fault slip,'' a ...

      Ground Failure Study Shows Deep Landslides Not Reactivated by 2018 Anchorage Quake
