Coastal boulders as evidences of high-energy marine events from Diu Island, west coast of India: storm or palaeotsunami?

Testing the numerical models for boulder transport through high energy marine wave event: An example from southern Saurashtra, western India

“…The present study area is located in the southeastern part of Southern Saurashtra region ( Fig. 1), which falls under shadow zone for tsunami waves originating from the MSZ (Prizomwala et al, 2015). Similarly, Owen Fracture Zone (OFZ) lies southwest of the present study area which is strike slip in nature, hence can only lead to weak tsunamis (Jaiswal et al, 2008).…”

“…Limited attempts suggest this coastline being prone to extreme wave events in historical as well as geological past Meshram et al, 2011;Sangode and Meshram, 2013;Prizomwala et al, 2015). In limited instances, observed as well as modeled data is available pertaining to effect of storms on southern Saurashtra coastline (Dube et al, 1985;Shaji et al, 2014), which enables us to examine and test the mathematical equations used for deducing wave origin.…”

Enhanced Field Observation Based Physical and Numerical Modelling of Tsunami Induced Boulder Transport Phase 1: Physical Experiments

“…In most cases, the event itself is not known (e.g. Hisamatsu et al, 2014;Prizomwala, 2015). Therefore, none of the hydrodynamic variables such as wave length, wave height or amplitude is known; they need to be estimated from today's obtainable indicators, like boulder characteristics.…”

Paleoseismology: 2010-2016

“…In a study by Prizomwala et al (2015), the dimensions, morphology and other characteristics of the boulders on the coastal segment of Diu Island on west coast of India were used to understand the wave types that could have carried them to their present position. Although cyclonic storms could have been the carrying agents, the authors conclude that a 3.5-high tsunami wave is responsible for mobilizing these boulders to their final position.…”
