Facies analysis provides new insights into event bed deposition in a hadal trench environment
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

Abstract On March 9th $9\mathrm{th}$, 2023, three small earthquakes (3.8≤Mw≤4.5) $(3.8\le {M}_{w}\le 4.5)$ occurred near Umbertide (Central Italy), within 4 hours. Analyzing seismic ambient noise in the frequency band 0.1–1 Hz from six seismometers within 20 km of the Mw 4.5, we detect a significant drop in seismic velocity at the time of occurrence of

Plasma Conditions Govern the Reversible Transition Between STEVE and Picket Fence Emissions
Abstract On 6 May 2018, a remarkable subauroral optical event exhibiting three phases of evolution (Strong Thermal Emission Velocity Enhancement [STEVE] → Picket Fence → STEVE) and co‐occurrence with a stable auroral red arc was observed over Alberta, Canada.

On the Seeding of Equatorial Plasma Bubbles by Longitudinal Variations in the Meridional Wind
Abstract We report results from SAMI3/WACCM‐X simulations that small‐scale (∼ ${\sim} $few 100 km) longitudinal variations in the meridional wind provide seeds to initiate equatorial plasma bubbles (EPBs). The meridional wind variations generate variations in the ion density along the magnetic field via ion‐neutral collisions.

A Helicity‐Based Analysis of the Stratospheric Polar Vortex Evolution
Abstract The Arctic atmosphere in the winter months of the Northern Hemisphere is influenced by a stratospheric polar vortex, characterized by strong westerly circumpolar winds and extremely low temperatures. These vortices impact surface weather in various ways, and their dynamics may be affected by recent anthropogenic climate change.
