| Zusammenfassung |
| Pulinets et al. (2007) document anomalous changes in the ionospheric total
electron content (TEC) starting one week before the 16 October 1999 Hector
Mine earthquake. The authors maintain that this TEC anomalous change is a
precursor of the subsequent earthquake. In a previous paper, Afraimovich et
al. (2004) excluded that TEC variations, which occurred before the Hector
Mine earthquake, were induced by the preparation process of the seismic
event. Thomas et al. (2012) reach similar conclusions by performing new
analyses of the same TEC data which were investigated by Pulinets et al. (2007). They show that the TEC changes documented by Pulinets et al. (2007)
are not anomalous but normal variations on global scale, and, therefore,
these changes are not related to the localised seismic activity of the
Hector Mine area. This paper confirms the results of Afraimovich et al. (2004) and Thomas et al. (2012). Through the use of geomagnetic indices
time series it is shown that the presumed precursor of Pulinets et al. (2007) was a normal TEC variation induced by solar-terrestrial interaction. |
