| Zusammenfassung |
| Results of the ULF geomagnetic monitoring of the volcano Popocatepetl
(Mexico) and their analysis are summarized and presented for the period
2003–2006. Our analysis reveals some anomalies which are considered to be
of local volcanic origin: the EM background in the vicinity of the volcano
was found to be significantly noisier than at other reference stations;
sporadic strong noise-like geomagnetic activity was observed in the
H-component; some geomagnetic pulsations were observed only at the Tlamacas
station (located at 4 km near the volcano). The results are discussed in
terms of a physical mechanism involving the presence of a second magmatic
chamber within the volcano and, finally, further perspective directions to
study volcanic geodynamical processes besides the traditional ones are
given. |
