Extreme and catastrophic events pose challenges for normative models of risk management
decision making. They invite development of new methods and principles to complement …

We review work on extreme events, their causes and consequences, by a group of
European and American researchers involved in a three-year project on these topics. The …

Fire frequency in 21 forest planning regions of Portugal during the period 1975–2005 was
estimated from historical burnt area maps generated with semi-automatic classification of …

On the basis of detrended fluctuation analysis (DFA), a new method, moving cut data-DFA
(MC-DFA), was presented to detect abrupt dynamic change in correlated time series. The …

Wildfire is the primary cause of deforestation in fire-prone environments, disrupting the forest
transition process generated by multiple social-ecological drivers of modernization. Given …

The initial footprint of an earthquake can be extended considerably by triggering of clustered
aftershocks. Such earthquake–earthquake interactions have been studied extensively for …

The distribution of extreme event return times and their correlations are analyzed in
observed and simulated long-term memory (LTM) time series with 1/f power spectra. The …

By analyzing the Japan Meteorological Agency (JMA) seismic catalog for different tectonic
settings, we have found that the probability distributions of time intervals between …

The climate system is a classical spatiotemporal evolutionary dynamic system with
spatiotemporal correlation characteristics. Based on this, two-dimensional detrended …

Pre-failure damage accumulation in deformed rock as well as crack propagation in fracturing
geomaterials is accompanied with the generation of elastic (acoustic) waves. These …
