Fig. 5From: Earth’s free oscillations excited by the 2011 Tohoku earthquake recorded in multiple GPS networksThe same as Fig. 4, but for toroidal modes: a N/E-component for l = 2 (m = − 2, − 1,0,1,2); b N/E-component for l = 3 (m = − 3, − 2, − 1, 0, 1, 2, 3). The vertical solid/dashed lines indicate the PREM eigenfrequencies of the spheroidal/toroidal fundamental modesBack to article page
