Ground-penetrating radar (GPR) offers an efficient and non-invasive method of identifying characterising subsurface features. It has previously been used to investigate both tsunami deposits marine erosion surfaces from tsunamis as well the structure prograding beaches. The present study investigates beach at Meulaboh, western coast Aceh Province in Sumatra Island Indonesia, estimate volume sed...

Extreme coastal inundation associated with the 2004 Indian Ocean and 1945 Makran tsunamigenic-earthquakes highlight the risk of tsunamis to coastlines of the northern Oman Sea. Foraminifera have been used as indicators of paleotsunamis in the past where allochthonous tests, found in low-energy environments such as in coastal lagoons, ponds, and marshes, indicate marine overwash. In this study, ...

[1] The study describes the development, testing and applications of site-specific tsunami inundation models (forecast models) for use in NOAA’s tsunami forecast and warning system. The model development process includes sensitivity studies of tsunami wave characteristics in the nearshore and inundation, for a range of model grid setups, resolutions and parameters. To demonstrate the process, f...

This paper examines the relationships between social participation and disaster risk reduction actions. A survey of 557 households in tsunami prone areas in Phang Nga, Thailand was conducted following the 2012 Indian Ocean earthquakes. We use a multivariate probit model to jointly estimate the likelihood of undertaking three responses to earthquake and tsunami hazards (namely, (1) following dis...

A numerical model for the global tsunamis computation constructed by KOWALIK et al. (2005), is applied to the tsunami of 26 December, 2004 in the World Ocean from 80 S to 69 N with spatial resolution of one minute. Because the computational domain includes close to 200 million grid points, a parallel version of the code was developed and run on a Cray X1 supercomputer. An energy flux function i...

The invention as disclosed is a system for real time detection of tsunami waves. A tsunami is considered a "shallow water wave"; having a large wavelength compared to the ocean depth. A tsunami can have wavelengths ranging from 100 to 500 km, and amplitudes up to 60 cm (i.e., a pressure signal of up to 1 psi). At least one telecommunications grade optical fiber cable fitted with repeaters spann...

The 26th December 2004 Indian Ocean Tsunami (IOT) emanated from an Mw 9.2 earthquake that generated a 1600 km-long rupture along the Sumatran Megathrust and generated tsunami waves up to 30 m high. The IOT directly impacted the Bay of Bengal and east Africa, with over 283,000 people perishing. At the time, this catastrophic event was considered unprecedented and sparked intense investigations t...
