| Zusammenfassung |
| The problem of earthquake prediction has stimulated the research for
correlation between seismic activity and ionospheric anomaly. Many
observations have shown the existence of anomaly of critical frequency of
ionospheric F-region, foF2, before earthquake onset. Ionospheric
sounding has been conducted routinely for more than 60 years in China by
the China Research Institute of Radiowave Propagation (CRIRP), and deveoloped a very
powerful ability to observe the ionosphere. In this paper, we briefly
describe the anomalous variation of the foF2 before Ms8.0
Wenchuan earthquake (occurred on 12 May 2008 at 14:28 LT; 31.00° N,
103.40° E), which is a sign of the great interest arising in the
seismo-ionospheric investigation of Chinese researchers. Furthermore, we
introduce the routine work on seismo-ionospheric anomaly by the ground based
high-resolution ionospheric observation (GBHIO) network comprising 5 vertical
and 20 oblique sounding stations. |
