| Zusammenfassung |
| Fractal analysis of the total magnetic field (TMF) time series from 1997 to
2003 at Popocatépetl Volcano is performed and compared with the TMF-series
of the Teoloyucan Magnetic Observatory, 100 km away. Using Higuchi's fractal
dimension method (D). The D changes over time for both series were computed.
It was observed, when the time windows used to compute D increase in length,
both series show nearly the same behavior. Some criteria of comparison were
employed to discriminate the local effects inherent to volcano-magnetism.
The simultaneous maximum in D (1.8) of the TMF series at Popocatépetl
Volcano and the recovered volcanic activity indicates a scaling relation of
the TMF at Popocatépetl Volcano and demonstrates a link between the magnetic
field and volcanic activity. |
