Based on the existing provisions/operations of tsunami warning in the Indian Ocean, authors observed that detection as well as arrival time estimations of regional tsunami service providers (RTSPs) could be improved. In particular, the detection mechanisms have been eccentrically focussed on Sunda and Makran tsunamis, although tsunamis from Carlsbe...

Mussanah fishery harbour is an ambitious port development project undertaken by the Sultanate of Oman. The harbour expects to attract small to mid range fishing crafts in the locale and beyond. As such, the development of port layout required a comprehensive numerical modelling campaign to ensure safe berthing conditions inside the port while takin...

This paper presents a detailed technical study carried out during the modeling phase of proposed fishery harbour in Duqm, Oman. The study aimed at establishing nearshore wave climate through transforming available offshore wave data, followed by an adequacy assessment of wave tranquillity inside the port basin. Wave data offshore Duqm, obtained fro...

For proper implementation of tsunami warning protocols, local authorities require conclusive and swift information from a variety of pre-identified, international tsunami warning channels. Thus, tsunami detection, decision making, communication, and dissemination prove to be extremely crucial for subsequent decision making for evacuation. As the te...

Purpose – The purpose of this paper is to propose a methodology for a priori classification of natural disasters that occur in Sri Lanka, through the development of a set of weighted parameters based on the product of the disaster impact and the affected area, in order to prepare mitigation plans. Design/methodology/approach – Experts' opinions w...

The massive devastation of the Indian Ocean mega tsunami in 2004, clearly calls for an efficient early warning system for the Indian Ocean countries. The ‘Regional Watch Provider’ system currently planned makes some countries entirely dependent on the watch providers. We discuss a feasible and reliable tsunami detection mechanism for Sri Lanka that...

Disaster preparedness, mitigation and management in all its facets are a global concern. Despite being a rare occurrence, a tsunami can cause massive damage to property and livelihood, and cause many deaths. Considering the fact that two-thirds of the globe is covered by oceans, where most subduction zones that cause earthquakes are located, all co...

The giant tsunami that occurred in 2004 opened the eyes of many nations adjacent to the Indian Ocean, who had thus far believed that no such calamities would befall them. The disastrous consequences of the tsunami shattered livelihoods, apart from the well-known statistics of deaths and financial losses. While acknowledging the inevitable occurrenc...

Popularity of the remotely accessed cameras in construction industry has increased significantly in the last few years in North America. Construction Monitoring and Visualization Centre (CMVC) is a novel concept developed and recently launched by the University of Calgary's productivity research team. The purpose of CMVC is to remotely monitor cons...
