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.

Prediction of Mean Overtopping Discharge at Vertical Seawalls Using MLR and GLM Statistical Approaches

International Journal of Maritime Technology, 2015
Wave overtopping at breakwaters is one of their essential hydraulic characteristics when determining the design crest level. This study concentrates on developing a new practical formula on predicting wave overtopping, by implementing two different ...

Single Slope Shore Protection as a Wave Energy Catcher

MATEC Web of Conferences, 2018
Wave energy is being increasingly regarded in many countries as a major, promising and renewable resource. This paper presents the development of slope coastal protection as a wave energy converter by capturing sea water into the reservoir through ...

The SSG Wave Energy Converter: Performance, Status and Recent Developments

Energies, 2012
The Sea-wave Slot-cone Generator (SSG) is a Wave Energy Converter based on the wave overtopping principle; it employs several reservoirs placed on top of each other, in which the energy of incoming waves is stored as potential energy.

Irregular Wave Overtopping Rates

Coastal Engineering 1984, 1984
Methods for estimating wave overtopping of coastal structures are reviewed and compared with the very limited available data and with each other. The different methods yield results which can vary more than an order-of-magnitude. For vertical seawalls, the U. S.

Modelling Spatial and Temporal Controls on Leaky Wooden Dam Effectiveness for Catchment‐Scale Flood Mitigation in an Upland Catchment

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Natural Flood Management (NFM) is increasingly adopted as a sustainable strategy for mitigating flood risk. Among these measures, the installation of leaky wooden dams (LWDs) at catchment scale is a widely used intervention aimed at slowing flow and desynchronising runoff peaks between sub‐catchments, thereby reducing flood magnitude.

Overtopping of Berm Breakwaters Extension of Overtopping Formula

, 2005
In this paper is presented an improved version of the overtopping formula by Lykke Andersen & Burcharth (2004)valid for berm breakwaters with initial slopes of 1:1.25. In the present paper guidelines is given on how to modify the formula to take into account the initial slope angle.

STATISTICAL PROPERTIES OF SHORT-TERM OVERTOPPING

Coastal Engineering Proceedings, 1984
It has been recognized recently that large waves tend to form a group in random sea waves. Overtopping tends to occur particularly when a group of high waves attacks a sea wall. If the capacity of a storage reservoir inside the sea wall is not sufficiently large enough to store a total amount of overtopping brought about by a single group of ...

Direct Policy Search for a Risk‐Based Levee Design Framework With Scenario Reduction

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Risk‐based management of coastal flood risk using realistic, process‐based models poses computational challenges, particularly when addressing uncertainties like sea‐level rise. This study explores the use of direct policy search (DPS) as a state‐dependent, adaptive decision‐making approach for upgrading levee systems.
