Cellular-Automata Models Applied to Natural Hazards
Found in: Computing in Science and Engineering
By Bruce D. Malamud, Donald L. Turcotte
Issue Date:May 2000
pp. 42-51
The concept of self-organized criticality evolved from studies of three simple cellular-automata models: the sand-pile, slider-block, and forest-fire models. In each case, there is a steady input and the loss is associated with a power-law distribution of
Forecasting Earthquakes: The RELM Test
Found in: Computing in Science & Engineering
By Michael Sachs,Donald L. Turcotte,James R. Holliday,John Rundle
Issue Date:September 2012
pp. 43-48
Earthquakes don't have precursors that can be reliably used for earthquake prediction. However, distributions of earthquakes (seismicity) can be used to forecast an earthquake hazard. These distributions in space, time, and magnitude can be studied in a va...
