The NEAM Tsunami Hazard Model 2018 (NEAMTHM18) is a probabilistic hazard model for tsunamis generated by earthquakes. It covers the coastlines of North-eastern Atlantic, Mediterranean, and connected seas (NEAM). NEAMTHM18 was designed as three-phase project. first two phases were dedicated to development calculations, following formalized decision-making process based on multiple-expert protocol. third phase documentation dissemination. assessment workflow structured in Steps Levels. There...
Tsunami warning centres face the challenging task of rapidly forecasting tsunami threat immediately after an earthquake, when there is high uncertainty due to data deficiency. Here we introduce Probabilistic Forecasting (PTF) for early warning. PTF explicitly treats data- and forecast-uncertainties, enabling alert level definitions according any predefined conservatism, which connected average balance missed-vs-false-alarms. Impact forecasts resulting recommendations become progressively...

CAT-INGV is a service provider charge of Sea alerting Intergovernmental Oceanographic Commission (IOC)/UNESCO subscriber Member States Department Civil Protection potentially impending tsunami, framework Warning Mitigation System North-eastern...
Abstract. Site-specific seismic probabilistic tsunami hazard analysis (SPTHA) is a computationally demanding task, as it requires, in principle, huge number of high-resolution numerical simulations for producing inundation maps. We implemented an efficient and robust methodology using filtering procedure to reduce the needed while still allowing full treatment aleatory epistemic uncertainty. Moreover, avoid biases assessment, we developed strategy identify separately treat tsunamis generated...
Regional and global tsunami hazard analysis requires simplified efficient methods for estimating the inundation height its related uncertainty. One such approach is amplification factor (AF) method. Amplification factors describe relation between offshore wave maximum height, as predicted by linearized plane models employed incident waves with different characteristics. In this study, a new method developed that takes into account bathymetry proximal to coastal site. The present AFs cover...
The complexity of coseismic slip distributions influences the tsunami hazard posed by local and, to a certain extent, distant sources. Large concentrated in shallow patches was observed recent tsunamigenic earthquakes, possibly due dynamic amplification near free surface, variable frictional conditions or other factors. We propose method for incorporating enhanced subduction earthquakes while preventing systematic excess at depths over one more seismic cycles. uses classic k−2 stochastic...
Probabilistic Tsunami Hazard Analysis (PTHA) quantifies the probability of exceeding a specified inundation intensity at given location within time interval. PTHA provides scientific guidance for tsunami risk analysis and management, including coastal planning early warning. Explicit computation site-specific PTHA, with an adequate discretization source scenarios combined high-resolution numerical modelling, has been out reach existing models computing capabilities, tens to hundreds...

In seismically active regions with variable dominant focal mechanisms, there is considerable tsunami inundation height uncertainty. Basic earthquake source parameters such as dip, strike, and rake affect significantly the tsunamigenic potential directivity. Tsunami also sensitive to other properties bottom friction. Despite their importance, sensitivity these basic surprisingly sparsely studied in literature. We perform suites of systematic parameter searches investigate at towns Catania...

Inundation maps are a fundamental tool for coastal risk management and in particular designing evacuation planning. These turn necessary component of the tsunami warning systems’ last-mile. In Italy inundation informed by probabilistic hazard model. Based on given level acceptable risk, Italian authorities charge this task recommended to consider, as design intensity, average return period 2500 years 84th percentile model uncertainty. An available, regional-scale was used that covers entire...
Abstract Destructive tsunamis are most often generated by large earthquakes occurring at subduction interfaces, but also other “atypical” sources—defined as crustal and non-seismic sources altogether—may cause significant tsunami threats. Tsunamis may indeed be different sources, such earthquakes, submarine or coastal landslides, volcano-related phenomena, atmospheric perturbations. The consideration of atypical is important worldwide, it especially prominent in complex tectonic settings the...
SUMMARY We investigated the kinematic rupture model of 2018 Mw 6.8 Zakynthos, Ionian Sea (Greece), earthquake by using a non-linear joint inversion strong motion data, high-rate GPS time-series and static coseismic displacements. also tested results against tide-gauge recordings small tsunami generated in Sea. In order to constrain fault geometry, we performed several preliminary inversions assuming parameter values resulting from different published moment tensor solutions. The lowest cost...
SUMMARY Estimating coastal tsunami impact for early-warning or long-term hazard analysis requires the calculation of inundation metrics such as flow-depth momentum flux. Both applications require simulation large numbers scenarios to capture both aleatory variability and epistemic uncertainty. A computationally demanding step in simulating is solving non-linear shallow water (NLSW) equations on meshes with sufficiently high resolution represent local elevation accurately enough physics...
The complexity of coseismic slip distributions plays a pivotal role in shaping tsunami hazards from both near and distant sources. Recent research underscores the significance large shallow slips tsunamigenic earthquakes, driven by dynamic amplification free surface variable frictional conditions. Several novel methods are being proposed to incorporate depth-dependent features subduction earthquake models, possibly ensuring balanced long-term total across seismic cycles. This allows...
Tsunami preparedness strategies are essential in tsunami risk governance and management due to three main factors that characterize these phenomena: they may have great devastating potential, unpredictable until an earthquake occurs, move extremely fast. Preparedness prospective measures should be planned based on understanding a pre-event phase, best identify the emerging needs. Among them, evacuation planning is one of most relevant strategies, especially terms protecting lives.Tsunami...
Tsunami fragility curves for building classes are essential tools portfolio risk assessment of tsunami-prone regions. However, existing data comprises mainly empirical curves, which reflect the vulnerability local based on observed damage data. While useful, these have limited applicability in regions with no recorded tsunami events or insufficient This highlights need to expand database analytical particularly areas lacking records. To fill this gap, study proposes a comprehensive framework...
