| Zusammenfassung |
| On 12 May 2008 at 14:28 LT great earthquake (M=8.0) occurred at Wenchuan
(31.00° N, 103.40° E), China. The hourly values of
foF2 are analyzed over ten ionospheric observatories: Haikou
(20.00° N, 110.33° E), Kunming (25.00° N, 102.70° E), Guangzhou (20.00° N,
113.70° E), Chongqing (29.50° N, 106.40° E), Lhasa (29.63° N, 91.17° E), Lanzhou
(36.07° N, 103.87° E), Beijing (40.00° N, 116.30° E), Urumqi (43.75° N, 87.63° E),
Chuangchun (43.83° N, 125.30° E) and Manzhouli
(49.60° N, 117.45° E). With a new factor, effective
sunspot number Reff, the results show that there were giant positive
disturbances of foF2 around the epicentral zone on 9 May, 3 days prior to
the earthquake. Our results indicate that the observed positive ionospheric
disturbances were most possibly associated with the imminent earthquake and
the new analytic method has good prospects in practice. |
