Fig. 7From: Possible correlation between the vertical component of lithospheric magnetic field and continental seismicityComparisons of Bz’s horizontal gradient with active tectonics and the 10-year (2000–2010) seismic catalog. Background colors are for the horizontal gradient of Bz at 200 km altitude. Focal mechanism with different color and size are for earthquakes of different magnitudes and focal depths. Lines with different colors mark boundaries of different tectonic units (see Figs. 1, 2)Back to article page
