| Zusammenfassung |
| In this paper the first results of ULF (Ultra Low Frequency) geomagnetic
anomalies observed at Tlamacas station (Long. 261.37, Lat. 19.07) located at
4 km near the volcano Popocatepetl (active volcano, Long. 261.37, Lat. 19.02)
for the period March–July, 2005 and their analysis are presented.
The geomagnetic data were collected with a 3-axial fluxgate magnetometer
designed at UCLA (University of California, Los Angeles, 1 Hz sampling rate
frequency, GPS). Our analysis reveals some anomalies which are suspected to
be generated by local volcanic origin: the EM background in the vicinity of
the volcano is significantly noisier than in other reference stations; the
sporadic strong noise-like geomagnetic activity observed in the H-component;
locally generated geomagnetic pulsations (without preferred polarization)
are detected only at Tlamacas station. |
