A Review of Historical Volcanic Tsunamis: A New Scheme for a Volcanic Tsunami Monitoring System

Journal of Marine Science and Engineering
Tsunami monitoring and early warning systems are mainly established to deal with seismogenic tsunamis generated by sudden seafloor fault displacement. However, a global tsunami triggered by the 2022 Tonga volcanic eruption promoted the need for tsunami ...

Tsunami generation by dynamic displacement of sea bed due to dip-slip faulting [PDF]

, 2008
In classical tsunami-generation techniques, one neglects the dynamic sea bed displacement resulting from fracturing of a seismic fault. The present study takes into account these dynamic effects.

Analytical and Numerical Soliton Solutions of the Shynaray II‐A Equation Using the G′G,1G$$ \left(\frac{G^{\prime }}{G},\frac{1}{G}\right) $$‐Expansion Method and Regularization‐Based Neural Networks

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Nonlinear differential equations play a fundamental role in modeling complex physical phenomena across solid‐state physics, hydrodynamics, plasma physics, nonlinear optics, and biological systems. This study focuses on the Shynaray II‐A equation, a relatively less‐explored parametric nonlinear partial differential equation that describes ...

A Lagrangian model for wave-induced harbour oscillations [PDF]

, 1990
A set of equations in the Lagrangian description are derived for the propagation of long gravity waves in two horizontal directions for the purpose of determining the response of harbours with sloping boundaries to long waves. The equations include terms

Crisis Preparation, Capacity Building, and Community Resilience: Lessons From Maui

Nonprofit Management and Leadership, EarlyView.
ABSTRACT The 2023 Maui wildfires provide a unique context to explore the impact of nonprofit crisis networks taking a proactive role in community crisis response, leveraging resources, expertise, and networks. The Hawaiʻi Community Foundation (HCF) has been a key player in Maui's local response, providing critical support, mobilizing volunteers, and ...

Tsunami generated by a granular collapse down a rough inclined plane

, 2014
In this Letter, we experimentally investigate the collapse of initially dry granular media into water and the subsequent impulse waves. We systematically characterize the influence of the slope angle and the granular material on the initial amplitude of ...

Fundraising as Contracting: Why Nonprofits Accept In‐Kind Donations

Nonprofit Management and Leadership, EarlyView.
ABSTRACT In‐kind (nonmonetary) donations are a popular form of philanthropy that have received much less scholarly attention than monetary gifts. This study documents the prevalence of types of in‐kind giving and associated organizational practices, then explores links between the perceptions of nonprofit managers, organizational practices, and ...

GOVERNING EQUATIONS FOR MULTI-LAYERED TSUNAMI WAVES [PDF]

Science of Tsunami Hazards, 2009
In order to develop generalized governing equations for multi-layered long wave system, a three layer system was considered. It was anticipated that equations for top layer and bottom layer will be independent on number of intermediate layer(s) and ...
