Spatial Interactions Govern Tectonic Tremor Activities in the Nankai Trough: A Statistical Approach for Spatiotemporal Pattern Modeling and Anomaly Detection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Establishing a quantitative framework to evaluate the spatiotemporal patterns of slow earthquakes and to detect their anomalous activities is essential for understanding diverse slip behaviors on plate boundaries and seismic hazard assessment. In this study, we focus on deep tectonic tremors, which are one manifestation of slow earthquakes and

Seismological Characterization of Northern Hikurangi Margin Slow Slip Regions Associated With Normal Faults, Seamounts, and Seeps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract At the northern Hikurangi margin, Aotearoa New Zealand, slow slip events (SSEs) recur every 6–24 months to ∼ ${\sim} $30 km depth. Although shallow SSEs (0–10 km) are well‐studied offshore, the deeper portion (10–30 km) remains poorly understood, limiting insight into SSE initiation.

Geomagnetic Variability in a Post‐Superchron Geodynamo: Insights From the Deccan Traps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Studying long‐term geomagnetic field behavior is crucial for understanding Earth's evolution, as field variability reflects processes in the planet's deep interior. One key question concerns the relationship between field strength and polarity reversal frequency, particularly during the Cretaceous Normal Superchron (CNS), a prolonged interval ...

Electrical Conductivity of Carbonatite Melts to 20 GPa: Constraints on Partial Melting Atop the 410‐km Discontinuity and in the Lower Mantle Transition Zone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Deep‐origin carbonatite melts are considered to be the products of partial‐melting of the oceanic crust in the subduction zones. In this study, we conducted electrical conductivity (EC) measurements on two samples, the composition of which resemble the partial‐melting products atop the 410‐km discontinuity and in the lower part of the ...

Sea Surface Temperature and Salinity Changes in the Easternmost Mediterranean During the Pre‐Evaporitic Messinian Controlled by the Restriction at Gibraltar

Paleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract During the latest Miocene, the Mediterranean Basin was affected by extreme paleoceanographic and paleoenvironmental changes culminating with evaporite (gypsum and halite) formation during the Messinian Salinity Crisis (MSC: 5.97–5.33 Ma).
