Available in PDF, EPUB and Kindle. Book excerpt: Global Tectonics and Earthquake Risk discusses the geostatistical treatment of earthquake probabilities. The book reviews global tectonics and geologic history, including evidence of change, Pangaea, geochronology, tectonic revolutions, and the breakup of Pangaea. The book discusses the formation of Pangaea which later broke down into the present continental cores of Asia, Europe, Africa, Australian, Antarctica, and the Americas. The book describes the separation of North and South America from Europe, how Africa became established during the Cretaceous time, and how India split off from Africa to became welded to Asia at the Himalayas. The text also explains earthquake risk in terms of stochastic processes, point processes, and illustrates modeling of the earthquake process. The "Large-Earthquake Model" is based on a list of the largest earthquakes in the region, while a more sophisticated model requires the incorporation of non-Markovian effects (aftershock sequences). The book cites an application of investigations done on California where an earthquake of magnitude 5 is expected to occur every three months. An earthquake of magnitude 8 or greater is predicted to happen every 100 years but the book notes that the return period exceeds the range of the period of recorded data (which is only 31 years). Presented in another way, the text concludes that the probability of occurrence of an event of magnitude 8 earthquake or over in any given year is about one percent. The book can prove helpful for geologists, seismologists, meteorologists, or practitioners in the field of civil and structural engineering.
