Submarine landslides: processes, triggers and hazard prediction.
Huge landslides, mobilizing hundreds to thousands of km(3) of sediment and rock are ubiquitous in submarine settings ranging from the steepest volcanic island slopes to the gentlest muddy slopes of submarine deltas. Here, we summarize current knowledge of such landslides and the problems of assessing their hazard potential. The major hazards related to submarine landslides include destruction o...
متن کاملMechanisms of tsunami generation by submarine landslides: a short review
Wave formation and propagation due to submarine landslides are complex phenomena that may be divided into four parts: Landslide dynamics, energy transfer from landslide motion to water motion, wave propagation in open water, and wave run-up along the shores. This paper focuses on the energy transfer from landslide motion to water motion, i.e. the generation of tsunamis by submarine landslides.
متن کاملHydroacoustic investigationof submarine landslides at West Mata volcano, Lau Basin
Submarine landslides are an important process in volcano growth yet are rarely observed and poorly understood. We show that landslides occur frequently in association with the eruption of West Mata volcano in the NE Lau Basin. These events are identifiable in hydroacoustic data recorded between ~5 and 20 km from the volcano and may be recognized in spectrograms by the weak and strong powers at ...
متن کاملPhonological Awareness and its implications for Reading Acquisition
Researches of more than two decades has affirmed the importance of phonological awareness and its relation to reading acquisition. Chard & Dickson (1999) consider phonological awareness as a "cognitive substrate to reading acquisition" (p.1). This article explains Phonological awareness and its relation to reading acquisition.
متن کاملCentral-Upwind Scheme for Savage-Hutter Type Model of Submarine Landslides and Generated Tsunami Waves
We develop a new central-upwind scheme for a one-dimensional Savage-Hutter type model of submarine landslides and generated tsunami waves. Our scheme exactly preserves physically relevant steady-states, preserves positivity of water depth, is insensitive to choice of discretization of nonconservative products, and properly incorporates friction inherent in the model. We apply our scheme to a va...
