A study published in Nature Geoscience on August 26, 2025 shows that major tropical volcanic eruptions alter global flood patterns, reducing floods in the hemisphere of eruption and increasing them across the equator, depending on stratospheric aerosol distribution.
New research published on August 6, 2025, in JAMA estimates that 440 excess deaths occurred in Los Angeles County, California, from January 5–February 1, 2025, due to the Palisades and Eaton wildfires, compared with 30 direct deaths officially reported.
A massive submarine landslide structure was discovered along the southern slope of the Aleutian Shelf, about 16 km (10 miles) northwest of the 1957 M8.6 Andreanof Islands earthquake epicenter.
NASA’s Juno spacecraft has detected a new plasma wave mode in Jupiter’s auroral magnetosphere, where electron plasma frequency is lower than the ion gyrofrequency, an unprecedented condition in space plasma physics. The discovery was made during recent polar passes by Juno and is described in a study published last month by a team led by R. L. Lysak. Researchers propose this wave type, now called the Alfvén0-Langmuir mode emerges in extremely low-density, highly magnetized plasma.
A large-scale space hurricane observed over the magnetic North Pole on August 20, 2014, produced strong GPS signal scintillation and localized geomagnetic disturbances under geomagnetically quiet conditions, new research shows.
A new study published on July 18, 2025, in Science Advances presents the first high-resolution seismic images of a nascent subduction zone off the coast of British Columbia’s Haida Gwaii archipelago, revealing a developing megathrust fault capable of producing powerful earthquakes and tsunamis.
Machine learning algorithms applied to waveform data from 2008 to 2022 have revealed 86 276 earthquakes beneath the Yellowstone caldera, U.S., approximately 10 times more than previously recorded. The revised catalogue, published in Science Advances on July 18, 2025, was created by researchers from Western University, Universidad Industrial de Santander, and the U.S. Geological Survey.
Could “comet”3I/ATLAS be a piece of alien technology? A question that might sound straight out of a sci-fi movie is now being brought to the front of the space table by Abraham (Avi) Loeb the Baird Professor of Science and Institute director at Harvard University.
For the first time, astronomers have observed the condensation of solid planet-forming material in the protoplanetary disc of the protostar HOPS-315, located in the Orion B molecular cloud, about 1 300 light-years away.
Creep measurements along the Concord Fault show consistent right-lateral motion of 2–3 mm/year (0.08–0.12 inches/year), prompting a shift in the official fault trace by up to 500 m (1 640 feet) and placing urban homes and infrastructure directly within a newly defined hazard zone.
