Seismogenic Anomalies in Atmospheric Gravity Waves as Observed from SABER/TIMED Satellite during Large Earthquakes

Figure 2

The variation of geomagnetic indices during the period of earthquakes period. The left side panels present the geomagnetic , while the right side panels present the index. In (a) and (g), the geomagnetic indices and for the 2011 Tohoku earthquake are presented. The red vertical line indicates the earthquake day. Similarly, in (b)-(h), (c)-(i), (d)-(j), and (e)-(k) and (f)-(l), the same are presented for the Indian Ocean, first Nepal, second Nepal, Kumamoto, and Chiapas earthquakes, respectively, and the green and blue horizontal dashed are represented threshold value of an occurrence of a storm.
