Potential reasons for ionospheric anomalies detected by nonlinear principal component analysis just before the China Wenchuan earthquake, and their relationship to source conditions
Nonlinear Principal Component Analysis (NLPCA) Principal Component Analysis (PCA) Total Electron Content (TEC),
2015/8/27
Nonlinear principal component analysis (NLPCA) was performed to examine the total electron content (TEC) anomalies for the China Wenchuan earthquake of May 12, 2008 (= 7.9). This was applied to global...
Global nonlinear optimization for the estimation of static shift and interpretation of 1-D magnetotelluric sounding data
Magnetotelluric sounding global nonlinear optimization static shift TE and TM mode apparent resistivity phase
2015/8/27
In the presence of conducting inhomogeneities in near-surface structures, apparent resistivity data in magnetotelluric sounding can be severely distorted. This is due to electric fields generated from...
