New study confirms AMOC is on tipping course

New study confirms AMOC is on tipping course

A new study published in Science Advances by René M. Van Westen, Michael Kliphuis, and Henk A. Dijkstra on February 9, 2024, unveils a physics-based early warning signal indicating the Atlantic Meridional Overturning Circulation (AMOC) is on a tipping course towards collapse.

Study unlocks clues to tectonic plate behavior between major quakes

Study unlocks clues to tectonic plate behavior between major quakes

Researchers from Penn State and Brown University have uncovered how rocks from ancient subduction zones can forecast tectonic behaviors between significant earthquakes, enhancing our ability to predict such natural disasters.

Research points to strong moonquakes from lunar faults, impacting future missions

Research points to strong moonquakes from lunar faults, impacting future missions

A recent study published in the Planetary Science Journal by T. R. Watters and colleagues in 2024 highlights the contractional deformation and associated seismicity at the lunar south pole, particularly within the de Gerlache Rim 2 Artemis III candidate landing region, raising concerns for future robotic and human exploration.

New study revises the origin of continents without the need for plate tectonics

New study revises the origin of continents without the need for plate tectonics

A group of geoscientists have recently challenged the conventional understanding of continental formation by presenting evidence that the origins of continents can be explained by internal geological forces alone, without initiating plate tectonics. The study highlights the role of oceanic plateaus in the early Earth’s crustal development.

Introduction of Oceanic Mid-plate Superstructures (OMS) in volcanic studies

Introduction of Oceanic Mid-plate Superstructures (OMS) in volcanic studies

New research introduces the concept of Oceanic Mid-plate Superstructures (OMS) to describe large volcanic structures formed from various volcanic sources over time. The study focuses on the Melanesian Border Plateau (MBP), an example of an OMS, revealing its formation through four distinct volcanic episodes, combining hotspot activity and lithospheric movements, contributing to around 222 000 km² of intraplate volcanism.

New insights reveal Earth’s inner core exhibits 8.5-year wobble

New insights reveal Earth’s inner core exhibits 8.5-year wobble

Researchers from China have confirmed an 8.5-year Inner Core Wobble (ICW) in Earth’s polar motion and length-of-day variations, revealing a static tilt of about 0.17 degrees between the inner core and mantle, challenging long-standing assumptions about Earth’s internal dynamics.

Research reveals Hunga Tonga’s eruption caused an unexpectedly large loss of ozone

Research reveals Hunga Tonga’s eruption caused an unexpectedly large loss of ozone

The January 15, 2022, eruption of the Hunga Tonga-Hunga Ha’apai volcano produced the largest underwater explosion ever recorded, injecting an unprecedented amount of water vapor into the stratosphere, causing significant ozone loss and rapid aerosol formation, according to recent studies.

InSight mission confirms eight meteoroid impact events on Mars

InSight mission confirms eight meteoroid impact events on Mars

A team of researchers utilizing data provided by NASA’s InSight mission has confirmed two new seismic events caused by meteoroid impacts on Mars, bringing the total number to 8. The study, employing a combination of seismic data and orbital imagery, has successfully pinpointed fresh impact craters, enhancing our understanding of Martian surface and atmospheric interactions.

Study of Iceland volcano eruption reveals new insights into volcanic fountaining

Study of Iceland volcano eruption reveals new insights into volcanic fountaining

A team of Earth scientists, meteorologists, geologists, and volcanologists has formulated a new theory explaining the phenomenon of volcanic fountaining. This breakthrough is based on the analysis of the 2021 Fagradalsfjall eruption in Iceland, as reported in the journal Nature Communications.
