Eera earthquake software

Modern seismograph networks can locate up to hundreds of thousands of earthquakes annually, providing a continuous and sometime overwhelming stream of data.

ZMAP is a set of tools driven by a graphical user interface GUI , designed to help seismologists analyse catalogue data. ZMAP is primarily a research tool suited to the evaluation of catalogue quality and to addressing specific hypotheses; however, it can also be useful in routine network operations. ZMAP was first published in , with the last major release, version 6. Or click here to download a. Geological Society of America Abstracts with Programs.

Ground response analysis is used to predict the movements of the ground and develop a design response spectrum in order to determine the dynamic stresses and strains and earthquake forces.

The profile was studied by using various methods of soil response analysis and finally, the results were examined. Hashash, Y. Park, and j. Biglari, M. Civil Eng 11, no. Idriss, I. Ince, G.
