The Evolution of a Polar Cap Patch Into a Blob in the Nightside Ionosphere: Direct Observations of Multiple Blob Formation Mechanisms Acting Simultaneously on the Same Plasma

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract A polar cap patch was observed to exit the polar cap to become a blob as it entered the auroral oval on the nightside of the Earth under moderately quiet geomagnetic conditions (Kp = 3−). Auroral particle precipitation led to an increase in the electron density of the blob.

Quiet‐Time Equatorial Ionization Anomaly Reversal Observed by the Satellites of Defense Meteorological Satellite Program (DMSP) and Ionospheric Connection Explorer (ICON)

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We investigated the quiet‐time temporal variations of the Equatorial Ionization Anomaly (EIA) and underlying plasma fountain observed in the topside ionosphere during the various F‐region equatorial E × B drift events recorded by the Jicamarca Incoherent Scatter Radar and simulated by SAMI3.

Global GNSS Observation of Mesoscale Ionospheric Irregularities (2006–2024)

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Mesoscale ionospheric irregularities are statistically investigated using an unprecedented 19‐year long‐term global GNSS (Global Navigation Satellite System) TEC (total electron content) data set. These irregularities are represented by ionospheric fluctuations within a 5°× ${}^{\circ}\times $ 3.75° ${}^{\circ}$ (latitude by longitude) region ...

Contribution of the Rheologically Weak Lower Crust to Contemporary Crustal Motions in the Southeastern Tibetan Plateau, China

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The southeastern Tibetan Plateau (SETP) plays a pivotal role in accommodating intra‐continental deformation driven by the ongoing India‐Eurasia convergence. However, its contemporary surface vertical motions and the underlying geodynamic processes remain highly debated.

Fault Kinematics of the 2019–2026 Puerto Rico Earthquake Sequence: Conjugate Faulting Within a Zone of Oblique Subduction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...
