In this paper, we first introduce data collection and data conversion methods in N-MT electromagnetic observation system, so that they can be easier written into the oracle precursor database. Second, we research application methods of these data in earthquake prediction, and compute the second value of the N-MT electromagnetic field observation system and FHDZ-M15 geomagnetic field integrative observation...
A method of two-threshold expectation maximum and Markov random field is presented to automatic detection of terrain surface changes after the Wenchuan earthquake, on May 12, 2008, using multitemporal ALOS PALSAR images. As an example in the Beichuan area, three kinds of terrain surface changes, i.e., scattering enhanced, reduced, and no-changed, are automatically detected and classified. By using...
