Quantitative Prediction of Earthquake Occurrence as Stochastic Phemomena

The feasibility of using microstrip gas detector as radon detector for earthquake prediction

In the last decade, several studies have concluded that elevated concentrations of radon gas in soil or groundwater could be the sign of an imminent earthquake. It is believed that in case of sudden movement of rocks before earthquake, radon is released from the depth of ground and reached the surface. In this way, by measuring Radon concentration change, earthquake prediction is possible. In t...

Statistical Seismology: Physical and Stochastic Modelling of Earthquake Occurrence and Forecasting

Using earthquake intensities to forecast earthquake occurrence times

It is well known that earthquakes do not occur randomly in space and time. Foreshocks, aftershocks, precursory activation, and quiescence are just some of the patterns recognized by seismologists. Using the Pattern Informatics technique along with relative intensity analysis, we create a scoring method based on time dependent relative operating characteristic diagrams and show that the occurren...

The 1992 Landers Earthquake Sequence: Earthquake Occurrence and Structural Heterogeneities

The June 28, 1992, Mw 7.3 Landers earthquake occurred in the southeastern Mojave Desert, California. Over 10,000 aftershocks of the earthquake were recorded by the Caltech-USGS Southern California Seismic Network (SCSN) in 1992. To investigate the relationship between complexities in the crustal structure and variations in seismicity, we have used a tomographic method to invert 145,098 P wave a...

Stochastic Synthesis of Earthquake Catalogs

A model of earthquake occurrence is proposed that is based on results of statistical studies of earthquake catalogs. We assume that each earthquake g nerates additional shock• •h a probability that depends on time as t -'1 . This assumption together with one regarding the independence of branching events on adjacent branches of the event 'tree,' is sufficient to permit the generation of complet...
