The application of big data in early warning systems (EWS) for multi-hazard risk management is becoming increasingly popular due to its enormous potential. Nevertheless, despite noteworthy achievements, there are still several enduring obstacles. This study aims to evaluate the advantages and difficulties through a comprehensive SWOT (strengths, weaknesses, opportunities, threats) analysis and ...

A research model to simulate the propagation of tsunamis caused by different mechanisms was developed in this paper. These mechanisms are submarine earthquakes, landslides and collapse of volcano calderas. The model is based upon the non-linear shallow-water hydrodynamic equations with horizontal viscosity and friction with the seabed. It also includes a flooding/drying algorithm. This model was...

More than forty years after the 23 November 1980 earthquake, which devastated the Campania and Basilicata regions, causing the destruction of a large number of towns and the death of around three thousand people, we have tried, through a large survey, to understand how and to what extent the urban fabric and the most affected communities have been rebuilt. Our main objective was to show, on one...

Extreme weather (heat waves, floods, drought, tropical storms, and tornados) has intensified as a result of climate change. In particular, the effects of climatic hazards on remote communities are more severe due their limited access to resources (e.g., health, socio-economics, sewer, stormwater, and drinking water systems), causing a dichotomy between urban cities and remote regions. For examp...

Among the anomalous geophysical phenomena observed preceding earthquakes, specific attention has been given to VLF/LF, ULF (very low frequency/low frequency, ultra-low frequency) electromagnetic (EM) emissions, recorded before earthquakes, because of an interesting correlation between them and seismic activity. Numerous scientific papers have been published on this topic, providing convincing e...

Pillared on the hydrodynamic simulation of an extreme flooding scenario, we subsequently evaluated the physical vulnerability of residential buildings utilizing an ad hoc developed indicator-based methodology. This method aimed to quantify the expected loss for each affected residential structure. The outcome of this assessment facilitated the creation of a detailed risk map, allowing for the i...

The author presents convincing evidence of the cosmic (planetary and solar) energy gravitational origin (related to the maximal and minimal combined planetary and solar integral energy gravitational influences on the internal rigid core of the Earth) of the maximal temporal intensifications of the global magnetic processes of the Earth. In fairly good agreement with the calculated date 2007.416...

Part of a requisite for natural hazard awareness and damage prevention in Egypt is the detailed monitoring of surface fault zones. The inventory of active faults and their risk assessment is an essential contribution to the safety of settlements, land use and infrastructure (railroads, highways, pipelines) and to damage prevention. Thus, this study aims to contribute to the detection, inventory...

The consolidated paper presents work carried out in the sphere of earthquake problems. On the base of theoretical and experimental studies, it is shown earthquake prediction possibility. There are discussed earthquake indicators and triggering exogenous factors in the example of the Caucasus region. Because the earthquake preparation process causes anomalous changes with complex characteristics...
