Dimensionality Reduction Techniques for Analyzing Tsunami Simulations in Hazard Assessment and Forecasting Applications

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract A wide selection of linear and non‐linear dimensionality reduction techniques is evaluated on synthetic tsunami data that is the basis for tsunami hazard assessment and computational forecasting. The data were computed from earthquake rupture forecasts (ERFs) supplying initial generation conditions and a linear long‐wave Green's function ...

Consideration of rupture kinematics increases tsunami amplitudes in far-field hazards assessments

Seismica
Tsunami hazard assessments often assume that co-seismic crustal deformation occurs instantaneously, particularly in probabilistic tsunami hazard analyses (PTHA).

Disaster Relief Through a Complex Adaptive System Perspective: Firms' Motivations, Activities, and the Role of Operations Adaptability in Overlapping Landscapes

Journal of Business Logistics, Volume 47, Issue 4, October 2026.
ABSTRACT Natural disasters disrupt the normal functioning of both communities and businesses. However, past literature often segregates the disaster relief view from the business continuity perspective, leaving a gap in understanding how firms can proactively support relief efforts.

VALIDATION OF THE JRC TSUNAMI PROPAGATION AND INUNDATION CODES

Science of Tsunami Hazards, 2014
In the last years several numerical codes have been developed to analyse tsunami waves. Most of these codes use a finite difference numerical approach giving good results for tsunami wave propagation, but with limitations in modelling inundation processes.

Assessing the Lagged Regional Economic Output Gaps After the 2015 South India Flood

Risk Analysis, Volume 46, Issue 10, October 2026.
ABSTRACT Natural hazards can adversely impact society, environment, and human well‐being. The development of mitigation strategies is typically based on estimates of economic losses, but such estimates are difficult when high‐resolution post‐disaster data are scarce.

Three Dimensional Numerical Simulation of Tsunami Generation and Propagation Due to Makran Subduction and run-up on Chabahar Bay and Makran Coasts

نشریه مهندسی دریا, 2019
Makran subduction located at the northwest of the Indian Ocean nearby the southern coast of Iran and Pakistan. Makran subduction is the source of tsunamis that threaten southern coast of Iran. In this article, generation and propagation of 1945’s tsunami

MODELING THE ASIAN TSUNAMI EVOLUTION AND PROPAGATION WITH A NEW GENERATION MECHANISM AND A NON-LINEAR DISPERSIVE WAVE MODEL [PDF]

Science of Tsunami Hazards, 2006
A common approach in modeling the generation and propagation of tsunami is based on the assumption of a kinematic vertical displacement of ocean water that is analogous to the ocean bottom displacement during a submarine earthquake and the use of a non ...

Along‐Strike Coupling Heterogeneity in Cascadia's Slow‐Slip Zone Constrained by GNSS and Reduced‐Order Rate‐And‐State Friction Modeling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with Bayesian inference of a quasi‐dynamic rate‐and‐state friction SSE‐cycle ...

Listening to Tsunami Waves Induced by Glacier Calving

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Processes at the ice–ocean interface play a central role in regulating the stability of marine‐terminating glaciers and ice sheets and drive ocean freshening and mixing. Iceberg calving—a mechanical loss of ice—generates ocean waves and promotes water‐mass exchange in glacierized bays.

Near‐Field Acoustic and Gravity Wave Modes in the Ionosphere Triggered by Ground Motion and Tsunami During the 2024 Mw7.4 Hualien Earthquake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The interaction between the atmosphere and other components of the Earth system, such as the solid Earth and the oceans, remains an open and active area of research. In particular, the dynamic response of the ionosphere to forcing from below, such as earthquakes and tsunamis, is not yet fully understood.
