Al2O3 in Anorthositic Slabs: A New Perspective on LLSVPs and Seismic Velocity Variations

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aluminum is a key component of crustal and mantle minerals, influencing melting and geochemical evolution within the Earth. Al2O3 exists as corundum at the surface and in upper mantle conditions, but transforms into high‐pressure phases like Rh2O3(II) at lower mantle depths, enabling stability over a wide pressure range.

Mechanisms for Decadal Variability of Ocean Heat Uptake Inferred From Adjoint Sensitivities

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The occurrence of a period of slowdown in surface air temperature increase from 1998 to 2013 despite continued greenhouse gas emissions (the warming hiatus) has suggested that ocean heat uptake (OHU) is susceptible to decadal variability. Here, we identify mechanisms that lead to decadal changes in OHU to revisit the origin of the warming ...

Characteristics of Seismic Energy Rate Functions of Shallow Tremors

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (<104 J) shallow tremors. As the seismic radiated energy increases, the energy rate functions become more complex and are better ...

Layered Seismic Anisotropy and Tectonics of the Anatolian Plate

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Anatolian tectonics are associated with slab retreat in the west and gravitational potential energy and continental collision in the east, leading to westward motion of Anatolia relative to Eurasia, partially accommodated on the North and East Anatolian transform faults.

19 Clustered Foreshock Sequences Along the San Jacinto Fault Zone: Possible Role of Frictional Heterogeneity in Extended Earthquake Nucleation

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Laboratory experiments and theoretical models suggest that earthquakes are preceded by extended nucleation phases, perhaps by slow but accelerating slip. However, such nucleation phases are hard to observe before natural earthquakes. Here we identify clustered foreshock sequences that could be nucleation signatures.
