Analysing Lava Risk for the Etnean Area: Simulation by Cellular Automata Methods

Crisci, G.; Gregorio, S. Di; Rongo, R.; Spataro, W.; … - In: Natural Hazards 20 (1999) 2, pp. 215-229

The model SCIARA, based on the “Cellular Automata” paradigm, is a versatile instrument whose scope is to analyse volcanic risk from lava flows. The possible fields of intervention are: [(a)] Long term forecasting of the flow direction at various eruption rates and points of emission by...

On-chip earthquake simulation model using potentials

Georgoudas, I.; Sirakoulis, G.; Scordilis, E.; Andreadis, I. - In: Natural Hazards 50 (2009) 3, pp. 519-537

A two-dimensional (2-D) Cellular Automata (CA) dynamic system constituted of cells-charges has been proposed for the simulation of the earthquake process. The CA model has been calibrated with the use of real data. The calibration incorporates major seismic characteristics of the area under...

A dual effect of urban expansion on flood risk in the Pearl River Delta (China) revealed by land-use scenarios and direct runoff simulation

Du, Shiqiang; Rompaey, Anton Van; Shi, Peijun; … - In: Natural Hazards 77 (2015) 1, pp. 111-128

Since the late 1970s, the Pearl River Delta (PRD) in China has undergone a rapid transition from an agricultural landscape to a metropolitan area. The rapid urbanization has not only increased the area of impervious surfaces in the central plain; it has displaced farmland to the hilly peripheral...

Complexity Theory of Natural Disasters; Boundaries of Self-Structured Domains

Scheidegger, A. - In: Natural Hazards 16 (1997) 2, pp. 103-112

-organized ordered states 'at the edge of chaos', with a fractal attractor. Short of complete breakdown, such systems re-establish order … attractor, all subsets follow a power law which accounts for the distribution of the steps of recovery. As the domains of quasi …-stationarity at the edge of chaos are represented by finite windows, the power-law does not cover all magnitudes. The stationarity …
