The study of Earth’s systems, including its physical structure, natural processes, and interactions between the lithosphere, hydrosphere, atmosphere, and biosphere. Earth sciences investigate phenomena such as weather, earthquakes, and volcanic eruptions to understand our planet’s past, present, and future.
A quiet revolution is unfolding in the deep, where NASA’s SWOT satellite is turning ripples on the ocean’s surface into a map of the hidden world below—revealing lost mountain ranges, tracing ancient tectonic scars, and illuminating the secret pathways of heat and life undersea.
China has launched a new deep-Earth drilling project aiming to reach 15 km (9 miles), which would make it the deepest borehole ever drilled in the world. The initiative seeks to explore geological structures, tap into potential energy reserves, and enhance scientific understanding of the Earth’s interior.
A fleet of rapid response ocean bottom seismographs was deployed to monitor aftershocks and gather critical data on seismic activity following the M7.0 earthquake that struck offshore Northern California on December 5, 2024.
An analysis of Earth’s lower mantle showed the presence of previously undetected positive wave speed anomalies.
Researchers pinpointed the Zavaritsky volcano as the source of the massive 1831 eruption that caused global cooling and turned the sun blue. The discovery connects sulfur deposits in polar ice cores to a previously overlooked volcanic event in the remote Pacific.
Electromagnetic signals lasting up to 70 seconds were detected before an M6.4 earthquake struck western Nepal on November 3, 2023. Researchers operating magnetotelluric stations in the Ganga Basin have described this as an important observation in earthquake precursor studies.
The World Magnetic Model (WMM) 2025 was released by the NCEI and the BGS on Tuesday, December 17, 2024. The release forecasts changes in Earth’s magnetic field for the next 5 years as the magnetic north pole keeps moving faster leading to important improvements in global navigation systems.
The world’s largest iceberg A23a resumed its movement on December 13, 2024, after decades of being lodged on the seafloor.
Movements within Earth’s molten outer core are causing millisecond-scale changes in the length of a day (LOD), according to researchers from the Swiss Federal Institute of Technology Zurich (ETH Zurich). Their findings, reported on November 26, 2024, are based on historical eclipse data analyzed using advanced machine learning (ML) and it traces rotational speed variations over the past 3 000 years.
