| Zusammenfassung |
| In this paper we provide comments about the potential seismogenic origin of
magnetic disturbances that Di Lorenzo et al. (2011) observed from few minutes
before to about one hour after the 6 April 2009 L'Aquila earthquake. The
coincidence with the earthquake induced the authors to think that the
observed magnetic signals were linked to the main phase of the seismic event.
Here, we will discuss the unusual polarization in the X–Z plane of the
magnetic disturbances observed by Di Lorenzo et al. (2011), the model of
source that the authors have proposed for the generation of these signals,
and the time length of the magnetic data set shown in their paper. We will
also discuss some possible generation mechanisms for electromagnetic
seismogenic signals that could support the authors' findings. Finally, we
will consider seismic and geodetic data from L'Aquila area just before and
after the 6 April 2009 earthquake. We conclude that there is no evidence to
support the hypothesis that magnetic disturbances documented by Di Lorenzo et
al. (2011) had a seismogenic origin. |
