Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan
Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2284-2302, September 2026.Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main eruptive phase, and secondary events hours later.

Tides of the Midland: From Groundwater Into the River
Hydrological Processes, Volume 40, Issue 8, August 2026.Tides in a river that is NOT influenced by the ocean, is not in the coastal area and is more than 300 m above sea level are caused by groundwater tides. As the phases of the Moon change, the amplitudes of the streamwater oscillations vary synchronously with those of gravitational acceleration.

Current Sheet Statistics in the Magnetosheath
Frontiers in Astronomy and Space Sciences, 2020 The magnetosheath (MSH) plasma turbulence depends on the structure and properties of the bow shock (BS). Under quasi-parallel (Q||) and quasi-perpendicular (Q⊥) BS configurations the electromagnetic field and plasma quantities possess quite distinct ...
