| Zusammenfassung |
| On 6 April 2009 at 01:32:39 UT a strong earthquake occurred west of L'Aquila
at the very shallow depth of 9 km. The main shock local magnitude was Ml = 5.8
(Mw = 6.3). Several powerful aftershocks occurred the following days.
The epicentre of the main shock occurred 6 km away from the Geomagnetic
Observatory of L'Aquila, on a fault 15 km long having a NW-SE strike, about
140°, and a SW dip of about 42°. For this reason, L'Aquila seismic
events offered very favourable conditions to detect possible electromagnetic
emissions related to the earthquake. The data used in this work come from the
permanent geomagnetic Observatories of L'Aquila and Duronia. Here the
results concerning the analysis of the residual magnetic field estimated by
means of the inter-station impulse response functions in the frequency band
from 0.3 Hz to 3 Hz are shown. |
