Earthquakes, such as the Tohokuthe Christchurch and the Maule earthquakes, or the Afghanistan and Turkey earthquakes, are often devastating, resulting in wide-spread infrastructural damage and high number of fatalities. The public and decision makers are, therefore, interested in information about the time and location of future events. However, despite considerable research effort, scientists are only capable of making estimates about where big quakes are most likely to happen in the long term years to decades. There is yet no reliable way of predicting in the short term days to weeks or months when an earthquake of a given size will occur in a specific location.
See online documentation Coulomb 3 is designed to investigate Coulomb stress changes on mapped faults and earthquake nodal planes, and is intended both for publication-directed research and for university teaching and instruction.
One can calculate static displacements on any surface or at GPS stationsstrains, and stresses caused by fault slip, magmatic intrusion or dike expansion.
Problems such as how an earthquake promotes or inhibits failure on nearby faults, or how fault slip or dike expansion will compress a nearby magma chamber, are germane to Coulomb.
Geologic deformation associated with strike-slip faults, normal faults, or fault-bend folds is also a useful application. Calculations are made in an elastic halfspace with uniform isotropic elastic properties following Okada .
We believe that one learns best when one can see the most and can explore alternatives quickly. So the principal feature of Coulomb is ease of input, rapid interactive modification, and intuitive visualization of the results.
The program has menus, sub-menus, check-items, and dialogue boxes to ease operation. The internal graphics are suitable for publication, and can be easily imported into illustration or animation programs for further enhancements.3D Focal Mechanisms is a tool for viewing earthquake focal mechanism symbols three dimensionally.
This tool operates within the Environmental Systems Research Institute (ESRI®) GIS software ArcScene® 9.x. The earthquake was followed by many powerful aftershocks and a new earthquake () hit Nepal on Tuesday May Earthquake Forecasting and .

Chapters of this book focus on several aspect of seismology ranging from historical earthquake analysis, seismotectonics, and damage estimation of critical facilities.
The Earthquake Analysis section covers the analysis and interpretation of recorded wave forms and seisms. Data recorded by the Swiss Seismological Service (SED) and its counterparts elsewhere form the basis for numerous research and service projects.
techniques are most suitable for earthquake prediction. KEYWORDS: Earthquake, Data mining, Machine learning, Seismic data analysis, Prediction 1.
Introduction Earthquake prediction is an important topic. Extensive research is being done on it such as papers written by Asencio-Cortés et al. (), Aqdas et al. (), Uyeda (), Florido et al.
