The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Imagined Integration: The Logics of Japanese Immigrant Integration Policy

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT As governments develop immigrant integration policies, they draw on and express conceptions about what successful integration looks like—what we call “imagined integration.” Yet this imagination likely displays variation that matters for implementation: integration policymaking is increasingly multilevel as it involves subnational layers of ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, Volume 73, Issue 5, Page 1331-1351, August 2026.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, Volume 73, Issue 5, Page 1378-1402, August 2026.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...

Tsunami Traveling Ionospheric Disturbances Triggered by the 29 July 2025 Mw 8.8 Kamchatka Earthquake Observed in Japan and Taiwan

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated notable seismic and tsunami waves. The total electron content (TEC) derived by more than 1,400 ground‐based global navigation satellite system (GNSS) receiving stations in Japan and Taiwan is employed to examine the spatiotemporal evolution of seismic‐ and tsunami‐traveling ionospheric ...
