When waves propagate through weakly scattering but correlated, disordered environments they are randomly focused into pronounced branchlike structures, a phenomenon referred to as branched flow, which has been studied in a wide range of isotropic random media. In many natural environments, however, the fluctuations of the random medium typically show pronounced anisotropies. A prominent example...

We provide preliminary calculations of wave generation, propagation and inundation for the December 26, 2004 Indian Ocean tsunami. Calculations are based on Boussinesq model FUNWAVE and are carried out on a Cartesian grid with spatial resolution comparable to 2 minutes in latitude and longitude. Initial conditions are provided by the TOPICS model and are based on estimates of ground motion in f...

The 1896 Sanriku earthquake was a typical ‘tsunami earthquake’ which caused large tsunami despite its weak ground shaking. It occurred along the Japan Trench in the northern tsunami source area of the 2011 Tohoku earthquake where a delayed tsunami generation has been proposed. Hence the relation between the 1896 and 2011 tsunami sources is an important scientific as well as societal issue. The ...

We describe our knowledge-based service architecture for multi-risk environmental decision-support, capable of handling geo-distributed heterogeneous real-time data sources. Data sources include tide gauges, buoys, seismic sensors, satellites, earthquake alerts, Web 2.0 feeds to crowd source 'unconventional' measurements and simulations of Tsunami wave propagation. Our system of systems multi-b...

Massive landslides can generate large tsunamis and endanger human lives properties. While a number of laboratory experiments on either subaerial or submarine landslide-tsunamis have been conducted, few studies focused partially submerged events. The present study aimed to investigate the characteristics develop predictive equation that estimate their heights through three-dimensional used 114 d...

The June 15, 1896 Sanriku earthquake generated devastating tsunamis with the maximum run-up of 25 m and caused the worst tsunami disaster in the history of Japan, despite its moderate surface wave magnitude (Ms=7.2) and weak seismic intensity. This is a typical tsunami earthquake, which generates anomalously larger tsunamis than expected from its seismic waves. Previously proposed mechanisms of...

To assist the analysis of tsunami hazards for Qatar coastal areas were using numerical model. By Tsunamis waves created from submarine earthquakes magnitude (Mw) 8.6 and 9.0 in Richard scale along Makran Subduction Zone (MSZ) as well landslides with soil volume 1.25 to 2.0 km3 Iranian coast inside Arabian Gulf is considered. TUNAMI-N2KISR model (Al-Salem) was applied this study predict propagat...

Abstract: The Korteweg-deVries equation, used to describe long and solitary wave propagation on shallow water, later called soliton, besides describing phenomena ranging from the dynamics of plasmas to tsunami can be implemented into Cellular Neural Networks (CNNs), analog circuit which processes signals in real time with the aim to create a completely innovative generation of trasmission lines...

The Makassar Strait region has had the highest frequency of historical tsunami events for Indonesia. The strait has a seismic activity due to the convergence of four tectonic plates that produces a complex mixture of structures. The main tsunamigenic features in the Makassar Strait are the Palu-Koro and Pasternoster transform fault zones, which form the boundaries of the Makassar trough. Analys...
