Tsunami: Ocean dynamo generator [PDF]
Scientific Reports, 2014 AbstractSecondary magnetic fields are induced by the flow of electrically conducting seawater through the Earth's primary magnetic field (‘ocean dynamo effect’) and hence it has long been speculated that tsunami flows should produce measurable magnetic field perturbations, although the signal-to-noise ratio would be small because of the influence of ...

An Earthquake Source Sensitivity Analysis for Tsunami Propagation in the Eastern Mediterranean [PDF]
Oceanography, 2014 Accurate earthquake source parameters are essential input to tsunami hazard assessment and mitigation, including early warning systems. It is difficult to make accurate assumptions of earthquake source parameters where the tectonic setting is complex. To

Landslide‐generated tsunamis at Réunion Island [PDF]
Journal of Geophysical Research: Earth Surface, 2010 Landslides that occur on oceanic volcanoes can reach the sea and trigger catastrophic tsunamis. Réunion Island has been the location of numerous huge landslides involving tens to hundreds of cubic kilometers of material. We use a new two‐fluid (seawater and landslide) numerical model to estimate the wave amplitudes and the propagation of tsunamis ...

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Effect of tsunami load induced by earthquake at Manila Trench on transmission tower
Ain Shams Engineering Journal, 2021 The Manila Trench subduction zone is an active convergent plate margin between the South China Sea and northern Philippines. This strongly indicates a high probability for larger earthquakes that could potentially trigger a tsunami in the future and ...

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.

On the contribution of the horizontal sea-bed displacements into the tsunami generation process [PDF]
, 2012 The main reason for the generation of tsunamis is the deformation of the bottom of the ocean caused by an underwater earthquake. Usually, only the vertical bottom motion is taken into account while the horizontal co-seismic displacements are neglected in

Concept study of radar sensors for near-field tsunami early warning [PDF]
Natural Hazards and Earth System Sciences, 2010 Off-shore detection of tsunami waves is a critical component of an effective tsunami early warning system (TEWS). Even more critical is the off-shore detection of local tsunamis, namely tsunamis that strike coastal areas within minutes after generation ...
