The current prototype of a fully automatic earthquake tsunami hazard assessment system, “Tsunami Observer”, is described. transition the system to active phase operation occurs when information about strong (Mw ≥ 6.0) received. In first stage, vector field coseismic displacements Earth’s crust calculated by using Okada formulas. calculations, use made data on coordinates, seismic moment, focal ...

Probabilistic Hazard Assessment (PHA) provides an appropriate methodology for assessing space weather hazards and their impact on technology. PHA is widely used in geosciences to determine the probability of exceedance critical thresholds, caused by one or more hazard sources. has proved useful with limited historical data estimate likelihood specific impacts. also driven development empirical ...

Rockfall hazard assessment is not simple to achieve in practice and sound, physically based assessment methodologies are still missing. The mobility of rockfalls implies a more difficult hazard definition with respect to other slope instabilities with minimal runout. Rockfall hazard assessment involves complex definitions for “occurrence probability” and “intensity”. This paper is an attempt to...

Fires are among the main drivers of forest degradation in Amazonia, causing multiple socioeconomic and environmental damages. Although human-ignited sources account for most fire events extended droughts may magnify their occurrence propagation. The southwestern a transnational region shared by Brazil, Peru, Bolivia known as MAP region, has been articulating coordinated actions to prevent disas...
