1+ week, 5+ day ago   (403+ words) Chinese Academy of Sciences deep-learning classifier detected 174,929 faint signals across 35 years of archived seismic data The AI method is as significant as the discovery itself. The signals in question are called PKP precursors: faint echoes that scatter off irregularities where…...

2+ week, 4+ hour ago   (374+ words) Deep beneath Earth’s surface, at a depth of nearly 2,900 kilometers, the mantle gives way to the liquid outer core. The dynamics of these extreme depths influence tectonic plate movements and contribute to earthquakes and volcanic eruptions. Yet directly studying these…...

2+ week, 5+ hour ago   (473+ words) Accurate, comprehensive, and spatially continuous monitoring of mining-induced surface subsidence is essential for geohazard prevention, ecological restoration, and safe mining. Conventional approaches, however, are limited by the sparse spatial distribution of GNSS observations, the difficulty of InSAR in resolving large…...

2+ week, 2+ day ago   (332+ words) Researchers at the Institute of Geology and Geophysics, Chinese Academy of Sciences, created a new deep learning tool to spot PKP precursors—faint seismic waves that appear just before stronger ones as they bounce off irregularities near the core-mantle boundary....

3+ week, 4+ day ago   (621+ words) My job involves assessing what might result from geologic hazards on the ocean floor, including earthquakes, landslides, and volcanic activity. One of the biggest challenges is that we hardly ever see these things happen. There are, however, different ways to…...
