Fig. 2.From: Modeling of local disturbance formation in the ionosphere electron concentration before strong earthquakesDaily TEC variations above stations ORID, TUBI, MATE, and NOT1 for the period 3–9 January 2006 (1 TECU = 1016 el m−2). Thin lines are current variations of TEC, and thick lines are median values. The arrows note the moment of the earthquake.Back to article page
