Webb20 mars 2024 · Probabilistic Tsunami Hazard Assessment (PTHA) is a method that has been developed to predict tsunami hazards with a return period of hundreds to thousands of years, beyond the limited availability of historical data. The PTHA method can provide important information that supports tsunami risk management measures. WebbThe study of tsunami hazards in Thailand has been an ongoing topic of research. However, the hazards from tsunami sources based on probabilistic study and population risk are still unclear. In this study, potential tsunami sources along rupture zones were selected.
WebbA probabilistic hazard analysis of a tsunami generated by a subaqueous volcanic explosion was performed for Taal Lake in the Philippines. The Taal volcano at Taal Lake is an active volcano on Luzon Island in the Philippines, and its eruption would potentially generate tsunamis in the lake. Webbför 2 dagar sedan · Given that there are various sources of uncertainties associated with the modelling of hazards and damage of assets/structures, a method is proposed in which the uncertainties are propagated systematically to arrive at the damage realization of road network (Fig. 1).The uncertainties are characterised for: (i) the primary and cascading …
