The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2837-2854, September 2026.
ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

Uneven Impacts of Seawall Heightening on Tsunami Risk Reduction under Rising Sea Levels: Probabilistic Scenarios from the Japan Trench

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2948-2965, September 2026.
ABSTRACT Disasters exacerbated by climate change have prompted adaptation measures, including seawall heightening, which is an effective approach to protecting coastal areas. However, the combined effect of rising sea levels and tsunamis can create a compound coastal hazard, in which long‐term sea level rise amplifies the impact of tsunamis.

Wave overtopping on a low-crested seawall under extreme waves [PDF]

Extreme waves in global nearshore regions, frequently accompanied by wave setup, can transform seawalls into low-crested structures. Such events pose threats to coastal infrastructure due to enhanced overtopping and intense hydrodynamic loads imposed on ...

The Fargo‐Moorhead Diversion: Flood Protection or Sprawl Promotion?

River Research and Applications, Volume 42, Issue 7, Page 1562-1572, September 2026.
ABSTRACT Urban growth and development opportunities are needed worldwide, but growth and development must be hazard‐aware and should follow smart‐growth principles. The $2.89 billion Fargo‐Moorhead Area Diversion Project was designed to provide flood protection following damaging floods on the Red River of the North.

Discrete Boltzmann Modeling of Two‐Layer Shallow Water Flows

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Within the framework of discrete Boltzmann modeling (DBM), a two‐layer discrete Boltzmann model (D2Q16‐2) is proposed for the simulation of shallow water flows, aiming to overcome the limitations of conventional depth‐averaged models in representing layered flow structures and the reduced numerical stability of classical lattice Boltzmann ...

Numerical Investigation of Wave Overtopping in Impermeable Seawalls Coated with Sand-Based Porous Media [PDF]

Numerical Methods in Civil Engineering
A seawall's structural integrity can be damaged by wave overtopping. To mitigate wave overtopping, this study investigates the effectiveness of incorporating a porous layer into impermeable seawalls.
